## Plants for Planting Quarantine Pest Evaluation Data S heet

May 11, 2011

In order to prevent the introduction of quarantine pests into the United States, § 319.37

- 2a allows the APHIS Administrator to designate the importation of certain taxa of plants for planting as not authorized pending pest risk analysis (NAPPRA). APHIS has determined that the following taxa should be added to the NAPPRA category. In accordance with paragraph (b)(1) of that section,

this data sheet details the scientific evidence APHIS evaluated in making the determination that the taxa are hosts of a quarantine pest.

Quarantine Pest: Anoplophora chinensis

Hosts: See Host List below

Status: This pest and most of these hosts were regulated under a Federal Order dated April 1,

2011.

__________________________________________________________________________

Taxonomy and description of the pest:

Anoplophora chinensis (Forster) (Coleoptera: Cerambycidae)

Common name

– C itrus longhorned beetle (CLB)

Known d istribution :

Afghanistan 21 , China 1,4 , Croatia 14 , European Union 1,3,4,8

- 18 , Japan 1, , Indonesia 1,4, , Republic

of Korea 1,4 , Korea Democratic People's Republic 1,4 , Madagascar 3 , Malaysia 4

, Myanmar 3, 4 , Philippines 1,4 , Taiwan 1, , and Vietnam 1,4

.

This pest is not known to occur in the U nited States.

Biology of the pest:

A. chinensis adults lay eggs in the trunk and exposed roots of live woody trees and

shrubs 2,3 . The life cycle of A. chinensis is one to two years, but may be as long as three years, depending on the climate and feeding environment 2,4,11 . The larva e feed on the pith and vascular tissue of the trunk and roots. In addition, adults feed on leaves, petioles and bark. Pupation occurs within the larval tunn els . A dults emerge from April to August with peak emergence from May to July depending on environmental conditions 3

.A

. chinensis can infest trees with a trunk diameter as small as 12.7 millimeter (0.5 inch).

Infested trees are difficult to detect dur ing inspection because larval development occurs

inside the tree

, frequently at the root collar. Infested plants for planting that have cleared port of entry inspection have been found at the importing nursery 1 . Sap and frass may be

visible for a short time after the larvae bore into the trunk 6 . Adults emerge in one to two

or more years 6 depending on host and environment 11

.

Damage p otential of pest:

A

. chinensis is a destructive wood boring pest attacking over 75 h ost genera, including

many economically important fruit, forest, and ornamental plant species 3 . The larval feeding tunnels increase the plant's susceptibility to disease and wind damage and reduce efficient water and nutrient transportation, which may result in reduced fruit produ ction and/or premature tree death 5 . In addition, adults feed on leaves, petioles and bark.

The most likely pathway for introduction and establishment of A. chinensis is in woody plants for planting, including dwarfed plants and in wood packing material via

international trade 3

.

Control:

Foliar insecticides are effective at controlling adult A. chinensis

, but have little effect on the wood boring larvae and pupae 4,6 . Eradication measures for A. chinensis are similar to

those used for Asian l onghor ned beetle and emerald ash borer. The only effective means of controlling the larval and pupal stages are to chip or burn potentially infested trees and

to use foliar insecticides for adults 4 . Systemic insecticides (soil drench or injected) may

be used as an eradication tool for larvae and pupae , however additional research is necessary to determine the effectiveness

.

## Plants for Planting Quarantine Pest Evaluation Data S heet

June 23, 2011

In order to prevent the introduction of quarantine pests into the United States, § 319.37

- 2a allows the APHIS Administrator to designate the importation of certain taxa of plants for planting as not

aut horized pending pest risk analysis (NAPPRA). APHIS has determined that the following taxa should be added to the NAPPRA category. In accordance with paragraph (b)(1) of that section,

this data sheet details the scientific evidence APHIS evaluated in maki ng the determination that the taxa are hosts of a quarantine pest.

Quarantine Pest: Bursaphelenchus cocophilus

Hosts: See Host List below

Status: This pest and most of these hosts were originally regulated under a Federal Order dated January 25, 2010.

__________________________________________________________________________

Taxonomy and description of the pest:

Bursaphelenchus cocophilus (Cobb, Goodey) Baujard (Aphelenchida: Aphelenchoididae) Synonym: Rhadinaphelenchus cocophilus Common name: Red Ring Nematode

Known d istribution :

Bursaphelenchus cocophilus is widespread in tropical America, from Mexico through

Central America and into South America 1

.

This nematode is not known to occur in the United States.

Biology of the pes t:

Bursaphelenchus cocophilus is a plant

- parasitic nematode that Rhynchophorus palmarum L. (Giant Palm Weevil) ingests as a larva while feeding on nematode

- infested palms, and transmits as an adult weevil during oviposition 2

. The most characteristic sympt om of infection is a reddish, concentric band of discolored tissue in the stem . External symptoms include a drop in fruit production, yellowing and senescence of fronds and“little leaf syndrome” where fronds are stunted in growth though they vary widely depending on host species, age, cultivar and environmental conditions 1 . This variability in symptoms and the inability to detect the “red ring” without destroying the plant make identification of early infection difficult. Local movement of the nematode occurs by its weevil vector but wider dissemination can only occur by the transport of infested palms.

Damage Potential of Pest:

Bursaphelenchus cocophilus is a serious pest of palms, causing up to 10

- 15% annual

losses 3 . Infected palms usually die within a few months. Most palm species appear to be susceptible to infection by the nematode and there is no known treatment for this disease..

Control:

Controlling the vector R. palmarum can help reduce nematodeinfestation but the most recommended method of control is the early removal and destruction of affected palms 4

.

Known host range:

Acrocomia spp

. 1,5

, Astrocaryum spp

. 5 Attalea spp. 1,5

, Bactris spp.( = Guilielma spp.) 5

, Cocos spp

. 1,5

, Elaeis spp.1,5, Euterpe spp

. 5

, Mauritia spp

. 1,5

, Oenocarpus spp. ( = Jessenia spp.) 5

, Phoenix spp. 1,5 , and Roystonea spp 1

.

Action under NAPPRA:

This quarantine pest was first regulated under a Federal Order issued on January 25, 2010

and is now being proposed for action under NAPPRA.

The importation of the following plants for planting, except seed, of all host genera are not authorized entry pending a pest risk analysis (NAPPRA) from the all countries

.

Acrocomia

, Astrocaryum

, Attalea, Bactris, Euterpe, Mauritia, Oenocarpus, Roystonea (=Oreodoxa)

The importation of the following plants for planting genera that are hosts of Bursaphelenchus cocophilus are currently regulated under either 7 CFR 319.15 or 7CFR 319.37 and these gen era are therefore not included, at this time, as potential candidates for listing on NAPPRA:

Quarantine Pest: Ceratocystis manginecans

Hosts: Mangifera 1 spp.

Status: This host genus was regulated under postentry quarantine (7 CFR 319.37

- 7)

.

________________________________________________________________________

Taxonomy and description of the pest:

Ceratocystis manginecans M. van Wyk, A. Adawi & M.J. Wingf. 2007 (Microascal es
, Ceratocystidaceae )

Common name

– mango killer or sudden wilt of mango

Known distribution:

Oman and Pakistan 2

Biology of the Pest:

The fungus, commonly known as mango killer or sudden wilt of mango, prevents the movement of water and nutrients from the roots to the branches and twigs. S ymptoms include dark staining of wood

, exudation of gum

, and leaf wilting 3

. As the disease

progresse s , branches gradually dry out until the whole plant dies 2

. This pathogen is not

known to be seed transmitted.

In Oman and Pakistan, the bark beetle Hypocryphalus mangiferae Stebbing (Coleoptera: Scolytidae) appears to play an important role in the spread and development of mango

wilt disease 2

. While it has not been proven to be a vector of C. manginecans , t he barkbeetle and its exit holes have been consistently found in infected mango trees 5,6

. H. mangifearae is widely distributed in India 2

, Samoa, Manga reva Island, Brazil and

Hawaii 4

.

The fungus can be transported in soil in the form of chlamydospores 3

Damage Potential of Pest:

Mango is an important fruit crop worldwide. M ango wilt disease has devastated the mango industry in Oman since its first oc currence. Since 1998, over 60,000 trees have

been killed or removed in Oman and m ango production has decreased by 43% since

1997 2

. Thousands of mango trees were affected by the disease and killed within six months after the appearance of the first symptoms

.

Known host range :

Mangifera spp

. 1

Action under NAPPRA:

Mangifera spp. was regulated under postentry quarantine (7 CFR 319.37

- 7) and is now being proposed for action under NAPPRA.

The importation of Mangifera spp. plants for planting

, except seed but including cut flowers and greenery , a host of Ceratocystis manginecans

, is not authorized pending a pest risk analysis (NAPPRA) from all countries

, golden bands appear on previously infected

needles

. These needles remain on the tree during the winter and early spring, and are cast shortly there after. The flush of new needles in spring occurs during the same time when basidiospores are being produced and released from teliospores on the previous year’s

infected needles 3

. Basidiospores are disseminated by wind

.

Damage potential of the pest:

C. abietis is thought to weaken its host and make it more susceptible to other pathogens, like the ascomycete Lophodermium picea

. L. picea was isolated slightly more often from chlorotic needle parts where C. abietis was already present. Other endophytic f ungi were also isolated more frequently from areas already infected by C. abietis

. This suggests that

the introduction of C. abietis to an area where L. picea is already an established pathogen could pose a very serious problem to Picea abies 3

. A similar synergistic effect may occur

on North American confirmed hosts such as P. engelmannii, P. rubens, P. sitchensis if this pathogen is introduced 4

.

Known host range:

Picea spp. 1

Action under NAPPRA:

The importation of Picea spp. plants for plant ing

, excluding seed but including cut flowers and greenery, a host of Chrysomyxa abietis

, is not authorized pending a pest risk analysis (NAPPRA) from all countries except Canada.

In order to prevent the introduction of quarantine pests into the United States, § 319.37

- 2a allows the APHIS Administrator to designate the importation of certain taxa of plants for planting as not authorized pending pest risk analysis (NAPPRA). APHIS has determined that the following taxa

sho uld be added to the NAPPRA category. In accordance with paragraph (b)(1) of that section, this data sheet details the scientific evidence APHIS evaluated in making the determination that the taxa are hosts of a quarantine pest.

Quarantine Pest: Lachnell ula willkommii

Hosts: Larix spp

. , Pseudolarix spp.

__________________________________________________________________________

Taxonomy and description of the pest:

Lachnellula willkommii (Hartig) Dennis 1

Common name

– European Larch Canker 2

Known distribution:

Belgium, Byelorussia, China, Czechoslovakia, Denmark, Estonia, Finland, France, Germany, Hungary, Ireland, Italy, Japan, Netherlands, Norway, Portugal, Romania, Sweden, Russia, United Kingdom, Canada ( Nova Scotia ) , and Maine (United St ates). 3

This pest is under official control in the United States.

Biology of the pest:

L. willkommii is most commonly found in coastal areas with oceanic climate, abundant moisture, and moderate winter temperatures 2

. L. willkommii most likely overwinte rs on dead twigs and fallen branches of Lari x 1 . Ascospores, which are produced year round, cause infections in autumn where insect feeding sites or dwarf shoots exist 2,4 . The infection process is slow, the first symptoms take 1

- 4 years after inoculation t o appear. Apothecia appear on lesions one or more years after infection and complete the life cycle. Apothecia are visible in cankers year round 2

.Damage potential of the pest:

Perennial cankers form on branches and main stems and expand during host dormancy. These cankers begin as circular depressions in the bark of small stems and almost always are found surrounding a dead dwarf shoot or twig. The stem appears swollen at the canker site, and can cause girdling as well as dead bark to fall off. Pr emature needle yellowing can occur in summer 2 . Incidence of infection on a natural stand of

Larix laricina in New Brunswick averaged 59% in the 1990’s. The high infection rates, as well as the lengthy amount of time it takes for symptoms to appear are ma in concerns regarding L. willkommii 2

.

Known host range:

Larix spp. and Pseudolarix spp. 2

.

Action under NAPPRA:

The importation of Larix spp. and Pseudolarix spp. plants for planting, except seed but including cut flowers and greenery

, that are hosts o f Lachnellula willkommii

, are not
authorized pending a pest risk analysis (NAPPRA) from all countries except the areas of Canada not regulated for Lachnellula willkommii

Quarantine Pest: Phytophthora alni subsp. aln i

Hosts: Alnus spp.

Status: This pest and host were regulated under a Federal Order dated June 22, 2009

__________________________________________________________________________

Taxonomy and description of the p est:

Phytophthora alni Brasier & S.A. Kirk 1

.

P. alni is a hybrid of two different Phytophthora parents. These parents are likely

P. cambivora and a Phytophthora species similar to P. fragariae 2

. There are three subspecies of P. alni , the P. alni subsp. alni being the most prevalent 1

.

Phytophthora alni is commonly known as both Alder Dieback and Alder Phytophthora.

Known distribution:

Austria, Belgium, Czech Republic, France, Germany, Hungary, Ireland, Italy, Lithuania, Netherlands, Poland, Slovakia, Slovenia, Sweden, UK, England, Wales, and Scotland 3

.

P. alni subsp. alni is not known to occur in the United States

Biology of the pest:

P. alni has been isolated from infected roots

, stems of alder trees, and from stream baiting 4,5,6 . The infectious part of the pathogen is mainly its zoospores 3 . It is homothallic(self fertile) and produces ornamented and semi

- ornamented oospores in cu lture as well

as in infected tissue. 3,7 . The viability of oospores appears to be low. Ideal temperatures for growth in culture are between 22.5

- 25.0° C, with the upper temperature limit about 30° C. Infection of a plant seems to occur usually at the coll ar level or, during flooding,

on the stem 3 . Trees suffer from root and collar rot, as well as disrupted vascular systems, resulting in death 1,3

.

The disease is most commonly associated with alder stands along riparian ecosystems as

well as in nurseries a ssociated with alder seedlings 8,9 . Studies in France showed that water flow played a role in disease development. Fewer diseased alders were found in sites where water flow was rapid compared to sites with slower water flow. In Germany,

alders that were planted on high hills or banks were less likely to show disease

symptons 11 . Higher summer temperatures and clay soils also increased prevalence of the pathogen 10 . In some cases tree decline took more than four years and some trees actually

overcame infec tion through inherent resistance mechanisms 8

.

Damage potential of the pest:

P. alni was first discovered in the UK in 1993 2 . Since then it has spread to over 18 countries in Europe 4

. While the origin of P. alni is unknown, information from Poland suggested that introduction of the pathogen to natural ecosystems may have occurred via

nursery

- infested seedlings planted throughout the country for reforestation 9 . The pathogen further established in the field via zo ospores in streams, particularly greater infection rates were found during the growing season when flooding occurred 11

.

In Europe this disease has already done extensive damage to Alder populations 3 . In inoculation tests, the North American Red Alder ha s shown to be susceptible to this pathogen 3

.

Known host range:

Alnus spp. 3,12

.

Action under NAPPRA:

This quarantine pest was last regulated under a Federal Order issued on June 22, 2009 and is now being proposed for action under NAPPRA.

The importation of Alnus spp. plants for planting, excluding seed but including cut flowers and greenery, a host of P. alni subsp. alni , is not authorized pending a pest risk analysis (NAPPRA) from all countries except Canada :Literature cited:

Quarantine Pest: Pseudomonas syringae pv. actinidiae

Hosts: Actinidia spp.

Status: This pest and host were originally regulated under a Federal Order dated November 10,

2010.

__________________________________________________________________________

Taxonomy and description of the pest:

Pseudomonas syringae pv. actinidiae Takikawa, Serizawa, Ichikawa, Tsuyumu and Goto is the causal organism of b acterial canker disease of kiwi fruit. This pathogen is a pathovar within the diverse bacterial species Pseudomonas syringae and is only known to

infect Actinidia spp . in the environment.

Known d istribution :

China 4

, Italy 4 , Japan 1 , 2 , Korea 1

, 3 , and New Zealand 5

.

Biology of the Pest:

Leaves, canes, pollen and stems are affected by Pseudomonas syringae pv. actinidiae . It

is not known to be seed transmitted. The pathogen may exist as a resident on the surface of mature fruit, but it is improbable that it would survive to infe ct seed or seedlings. Symptoms appear on trunks, leaders and overwintering canes from late winter to early spring as cankers or a ngular necrotic leaf spot s , longitudinal cracks along the petiole, oozing and wilting of branches

.Rusty

- brown bacterial ooze exudes from lesions and from apparently healthy buds, leaf scars, lenticels and joints of trunks, leaders and canes. Brown water

- soaked lesions with halos appear on leaves, and wilt or blight of vigorous canes and flower buds appear in late spring. L eaves of the kiwi plant are most susceptible to the pathogen just before maturity. Relatively low temperatures (50°

– 68 °F; optimum 59 °± 37.4 ° F), strong winds and heavy rainfall appear to promote the disease

.

Damage Potential of Pest:

P. syringae pv

. actinidiae is present in infected plant material and is thought to be introduced into new regions in nursery material. The pathogen can be dispersed in aerosols and can be carried between trees and adjacent orchards in wind

- driven rain. As a

wound

- infectin g pathogen, it can also be transmitted on orchard equipment such as pruning tools.

Bacterial canker of kiwifruit was first observed in Japan 1 , 2 and Korea 2 causing damage in

Actinidia spp. orchards. In 1992 the disease was first notice d in n orthern Italy 4 where it remained sporadic for 15 years ( until 2007/2008 ) whe n it began caus ing economic

losses 4 ; it is estimated that the economic losses (including impact on trade) due to P. syringae pv. actinidiae have reached 2 million Euros 4

.

Known host range:

Actinidia spp.

Action under NAPPRA:

This quarantine pest and its host were last regulated under a Federal Order issued on November 10, 2010 and is now being proposed for action under NAPPRA.

The importation of Actinidia spp. plants for planting

, except seed but including cut flowers and greenery

, a host of the Pseudomonas syringae pv. actinidiae , is not authorized pending a pest risk analysis (NAPPRA) from the all countries :

Quarantine Pest: Pseudomonas syringae pv. aesculi

Hosts: Aesculus spp

.

Status: This pest and host were regulated under a Federal Order dated January 7, 2010.

__________________________________________________________________________

Taxonomy and description of the pest:

Pseudomonas syringae pv. aesculi (PSA) is the causal organism of the disease bleeding canker of horse chestnut. PSA is a pathovar within the diverse bacterial species Pseudomonas syringae and is only known to infec t Aesculus spp. in the environment.

The symptoms greatly resemble Phytophthora infection, leading to the misidentification of the causal organism of this disease until recent research positively identified it as P. syringae pv. aesculi. 2

Known d istributi on :

The Netherlands, United Kingdom, Belgium, France, Germany, and India 1

This pathogen is not known to occur in the United States.Biology of the pest:

The earliest symptoms of infection are bleeding lesions that can range from red to yellow

or black. The lesions are usually located at the base of the tree expanding upward to branches and stems as the infection spreads. In dry conditions there may be a crust present near the exit wound. The tree crown may show leaf yellowing and early leaf drop. Girdling of the trunk or branch is possible within a few years. If bark is removed an

orange

- brown mottling may be present 1 . Bark may be cracked or missing 2

.

PSA has been successfully isolated from the surfaces of horse chestnut leaves, branches,

flow ers, and parts of the fruit 1 . Like other bacterial plant pathogens, spread of the organism is likely to be by rain and wind as well as insects visiting the bleeding cankers and human activity such as pruning.

Seed transmission is not known for this pat hogen.

Damage Potential of Pest:

Recent surveys have estimated that in the United Kingdom 35

- 50,000 horse chestnut trees (approximately 49 percent of the trees surveyed in 2007) are infected with this pathogen 3 and in the Netherlands 30 percent of horse chestnut trees are infected 1 . In Europe this disease is extremely damaging to the commonly planted A. hippocastanum

and A . x carnea 4 , although apparently the disease is found on all species of Aesculus in the Netherlands. Trees of all sizes and ages are affected. Young trees (10

- 30 years old) are apparently more susceptible with some dying within 3

- 5 years after symptom development 4 . Research is underway on the susceptibility of other Aesculus species, with the ultimate aim of finding possible sources of resistance 1 . Several species of Aesculus

are native to the United States 5 and A. hippocastanum is a widely planted ornamental tree. If these species prove to be susceptible, then the potential environmental and economic damage due to this pest would be significant.

Known host range:

Aesculus spp. 1

Action under NAPPRA:

This quarantine pest and its host were last regulated under a Federal Order issued on January 7, 2010 and is now being proposed for action under NAPPRA.

The importation of Aesculus spp. plants for planting , excluding seed but including cut flowers and greenery, a host of Pseudomonas syringae pv. aesculi, is not authorized pending a pest risk analysis (NAPPRA) from all countries except Canada.Literature cited:

Quarantine Pest: Rhynchophorus ferrugineus

Hosts: See Host List below

Status: This pest and these hosts were regulated under a Federal Order dated January 25,

2010.

__________________________________________________________________________

Taxonomy and description of the pest:

Rhynchophorus ferrugineus Olivier (Coleoptera: Curculionidae) Common names: Red palm weevil, Asian palm weevil

Known d istribution :

Rhynchophorus ferrugineus is native to tropical Asia, ranging from Pakistan through

Southeast Asia to Melanesia 1

. R

. ferrugineus has also been reported from Algeria 1

, C yprus 2

, Egypt 1

, France 3

, Greece 4

, Italy 5 , Iraq, Iran 1 , Morocco 6

, Portugal 7

, Spain 1

, Syria 8

, Turkey 9

, United Arab Emirates 1

.

Within the United States it is known only to occur in Orange County, California where it is currently under official control.Biology of the pest:

The life cycle of Rhynchophorus ferrugineus ranges from 45

- 139 da ys, depending on the climate, which allows for several generations in a year 9 . The female lays eggs in wounds or soft tissue of the plant and after hatching the larvae burrow into the stem creating large galleries that eventually weaken and destabilize th e tree. The damage caused by the larvae is only visible long after infestation, and by the time the first symptoms of the attack appear, they are so serious that they generally result in the death of the tree. The rapid spread of this insect is attributed to the nursery trade, specifically that of mature palms and offshoots

. Infestation by this stem borer is difficult to detect in the early stages and damage only becomes visible long after infestation 10

. There is no indication

thus far that seeds are a pa thway for infestation.

Damage Potential of Pest:

Rhynchophorus ferrugineus is a polyphagous weevil with the potential to be a serious pest in any area where palms are widely grown. Date palm populations have been particularly hard hit by this pest, with some considering it to be the most important pest of date palms in the world 11

.

Control:

The most

- widely used and effective means of reducing infestation is the chemical or mechanical killing of affected trees coupled with the trapping of adults using pheromone and/or appropriate plant material. Other control measures include treatments to save infested palms through the use of systemic insecticides injected into and around trees 11

. However, additional research is necessary to determine their effecti veness.

Known host range:

Areca spp , Arenga spp , Borassus spp 1 , Brahea spp 5

, Butia spp. , Calamus 12 , Caryota

spp., Chamaerops (synonym Trachycarpus ), Cocos spp , Corypha spp , Corypha spp.

, Elaeis spp. 1 , Livistona spp. 13 , Metroxylon spp. 1 , Oncosperma spp. 11 , Roystonia spp. (synonym Oreodoxa spp. ), Phoenix spp. , Chamaerops spp

. 1

Action under NAPPRA:

This quarantine pest and these hosts were first regulated under a Federal Order issued on January 25, 2010 and are now being proposed for action under NA PPRA.The importation of the following plants for planting, except seed but including cut flowers and greenery, that are hosts of R

. ferrugineus

, are not authorized pending a pest risk analysis (NAPPRA) from all countries :

Brahea, Butia, Calamus, Euterpe, Manicaria, Metroxylon, Oncosperma, Roystonea ( synonym Oreodoxa )

The importation of the following plants for planting genera that are hosts of R

. ferrugineus is currently regulated under either 7 CFR 319.15 or 7CFR 319.37 and these genera are there fore not included, at this time, as potential candidates for listing on

NAPPRA:

## Plants for Planting Quarantine Pest Evaluation Data S heet

June 22, 2011

In order to prevent the introduction of quarantine pests into the United States, § 319.37

- 2a allows the APHIS Administrator to designate the importation of certain taxa of plants for planting as not authorized pending pest risk analysis (NAPPRA). APHIS has determined that the following taxa should be added to the NAPPRA category. In accordance with paragraph (b)(1) of that section,

this data sheet details the scientific evidence APHIS evaluated in making the determination that the taxa are hosts of a quarantine pest.

Quarantine Pest: Rhynchophorus palmarum

Hosts: See Host List below

Status: This pest and most of these hosts were ori ginally regulated under a Federal Order dated January 25, 2010.

__________________________________________________________________________

Taxonomy and description of the pest:

Rhynchophorus palmarum (Linnaeus, 1758) (Coleoptera: Curculionidae)

Synonyms: Rhynchoporus .cycadia, R. depressus, R. longuinossis, Calandra palmarum Common names: Giant palm weevil, South American palm weevil

Known d istribution :

Rhynchophorus palmarum is widespread in tropical America, from Mexico through

Central America and into South America 1

.

This weevil has been intercepted in the United States in San Diego County, California where emergency action was taken and this pest is now under consideration for official

control.

Biology of the pest:The complete life cycle of Rhynchophorus palmarum ranges from 4 to 6 months

, depending on the climate, which allows for more than one generation in a year 2 . The female lays eggs in wounds or soft tissue of the plant and after hatching the larvae burrow

into the stem creating large galleries that eventually weaken and destabilize the tree. The damage caused by the larvae is usually only visible long after infestation, and by the time the first symptoms appear, they are so serious that they generally result in the death of the

tree 3

. R

. palmarum is also the main vector of the plant

- parasitic nematode Bursaphelenchus cocophilus 4,5

. The rapid spread of this insect is attributed to the nursery trade, specifically that of mature palms and offshoots

. Infestation by this stem borer is difficult to detect in the early stages and damage only becomes visible long after

infestation 3

.

Damage Potential of Pest:

Rhynchophorus palmarum is considered to be one of the most important pests on commercial palm plantations. Native to Neotropical forests this weevil is a serious pest affecting palm plantations and ornamental palms throughout Central and South

America 1, 3 . Aside from the direct damage that this pest poses to palms it is also the main

vector of Bursaphelenchus cocophil us
, commonly known as the red ring nematode 4,5

.

Control:

The most

- widely used and effective means of reducing infestation is the chemical or mechanical killing of affected trees coupled with the trapping of adults using pheromone and/or appropriate plant material. Other control measures include treatments to save infested palms through the use of systemic insecticides injected into and around trees 11

. However, additional research is necessary to determine their effectiveness.

Known host range:

Ac rocomia spp

. 1

, Attalea spp. 1

, Bactris spp. 1

, Dypsis spp

. 1 ( synonym Chrysalidocarpus

lutescens ), Cocos spp

. 1 , Desmoncus spp. 1 , Elaeis spp. 1 , Euterpe spp. 1 , Manicaria spp. 1

, Metroxylon spp. 1

, Phoenix spp

. 1

, Roystonea spp. (synonym Oreodoxa ) 1 , Sabal spp

. 1

, Syagrus spp

. 1

, Washingtonia spp. 1 and the only non

- palm main host, Saccharum spp. 1,2

.

Action under NAPPRA:

This quarantine pest was first regulated under a Federal Order issued on January 25, 2010 and is now being proposed for action under NAPPRA.

The importation of the following plants for planting, except seed but including cut flowers and greenery, that are hosts of R

. palmarum

, are not authorized pending a pest risk analysis (NAPPRA) from all countries :Acrocomia

, Attalea

, Bactris

, Desmoncus, Euterpe, Manicaria, Metroxylon, Roystonea ( synonym Oreodoxa ), Sabal , Syagrus, Washingtonia

The importation of the following plants for planting genera that are hosts of R. palmarum is currently regu lated under either 7 CFR 319.15 or 7CFR 319.37 and these genera are therefore not included, at this time, for listing on NAPPRA:

Dypsis ( synonym Chrysalidocarpus ), Cocos, Elaeis, Phoenix, Saccharum

- 2a allows the APHIS Administrator to designate the importation of certain taxa of plants for planting as not authorized pend ing pest risk analysis (NAPPRA). APHIS has determined that the following taxa should be added to the NAPPRA category. In accordance with paragraph (b)(1) of that section, this data sheet details the scientific evidence APHIS evaluated in making the deter mination that the taxa are hosts of a quarantine pest.

Quarantine Pest: Tomato severe leaf curl virus (ToSLCV)

Hosts: Solanum spp. (including syn. Lycopersicon spp.)

, Capsicum spp.

Status: This pest and these hosts were originally regulated under a Federal Order dated May 5,

2009.

__________________________________________________________________________

Taxonomy and description of the pest:

T omato

, Solanum lycopersicum (syn. Lycopersicon esculentum )

, and pepper, Capsicum

spp., are prone to a large number of begomoviruses (Geminiviridae) and other virus and

virus

- like diseases , many of which are quarantine pests

. The begomoviruses, the group to which Tomato severe leaf curl virus (ToSLCV) belongs, are major constraints to vegetable produ ction 1

.

Known d istribution :

ToSLCV has been reported from Guatemala, Nicaragua, Honduras 2 , and Mexico 3

.

ToSLCV i s not known to occur in the United States

Biology of the Pest:

Symptoms of ToSLCV include stunting, severe mosaic, yellowing, curling , distortion and

deformation of leaves. ToSLCV and the other begomoviruses are transmitted between plants by whiteflies. After acquisition by the whitefly vector, the begomoviruses are persistent in the whitefly and retained for anywhere from a few week s through the life of

the vector 6 . The virus can therefore be transmitted to a large number of hosts.Plant pathogens, including viruses and viroids are extremely difficult to detect during a port of entry inspection of the host plants, particularly in the absence of symptoms.

ToSLCV infects the entire plant, but is not known to be seed transmitted.

Damage Potential of Pest:

In Nicaragua, all tomato plants sampled in a field survey were infected with begomoviruses with ToSLCV present in most of the samples 1 . A similar begomovirus, tomato mottle virus, introduced into Florida caused an epidemic of severe proportions 4

. The threat of introduction of one or more of these viruses lead APHIS to develop the New Pest Response Guideline: Whitefly

- borne Gemi niviruses (Family Geminiviridae) 5

.

Known host range:

Lycopersicon 1,2,3 

### and Capsicum 1

.

Action under NAPPRA:

This quarantine pest was first regulated under a Federal Order issued on May 5, 2009 and is now being proposed for action under NAPPRA.

The importation of the following plants for planting genera, except seed, but including cut flowers and greenery, that are hosts of ToSLCV, are not authorized pending a pest risk analysis (NAPPRA) from all countries except Canada :

Solanum spp. ( including Lycopersicon), Capsicum spp.

Quarantine Pest: Tomato torrado virus (ToTV)

Hosts: Solanum (including Lycopersicon), Amaranthus, Atriplex

, Chenopodium

, Haloget on , Lepidium ( synonyms Senebiera, Coronopus), Malva, Polygonum

, Nicotiana and Spergularia

Status: This pest and these hosts were originally regulated under a Federal Order dated May 5,

2009.

__________________________________________________________________________

Taxonom y and description of the pest:

Tomato, Solanum lycopersicum , is prone to a large number of potential quarantine virus pathogens, including the many forms of Tomato yellow leaf curl virus, Tomato zonate spot virus, Tomato fruit yellow ring virus, Tomato curly stunt virus, and Tomato Marchitez virus. ToTV belongs a new picorna

- like group of plant viruses.

Known distribution:

Canary Islands, Spain 1 and Poland 4 . Tomato marchitez virus (ToMarV), a closely related viral pathogen of tomato, occurs in Mexico 5

.

This virus is not known to occur in the United States.Biology of the pest:

Tomato torrado virus was observed since 2001 in the region of Murcia, Spain, although not identified and reported until 2007 1,3 . A similar disease was observed in Poland in 2003 and identified and reported as ToTV in 2007 4 . ToTV was also reported from the Canary Islands in 2007 1 . ToTV is not known to occur in the United States. A closely related viral pathogen of tomato, Tomato marchitez virus (ToMarV), occurs in Mexic o 5

.

The host plants listed include environmental and greenhouse weeds that serve as alternate

hosts for ToTV and act as virus reservoirs 2

. Preliminary experiments indicate the

involvement of whiteflies as a vector of ToTV 3,6

.

Virus diseases and their c ausal agents are extremely difficult to detect during a port of entry inspection of the host plants especially in the absence of symptoms.

ToTV infects the entire plant but is not known to be seed transmitted.

Damage potential of the pest:

Infected pl ants exhibit very distinct necrotic, almost burn

- like symptoms on leaves and

stems and necrotic blotches or patterns on fruit which become deformed and unmarketable. Plant growth and yields are seriously reduced 2

Quarantine Pest: Xanthomonas axonopodis pv. punicae

Hosts: Punica spp. 1

__________________________________________________________________________

Taxonomy and description of the pest:

Xanthomonas axonopodis pv. punic a (Hingorani & Singh 1959) 1

Common name

– bacterial blight of pomegranate 1

.

Known distribution:

India, Pakistan, South Africa 1

.

This bacterial pathogen is not known to occur in the United States.

Biology of the pest:

Certain environmental factors such as increased temperature, rain, and low humidity facilitate the spread of the disease. Insects, rain splash, and the use of contaminated pruning tools ar e additional ways that the bacteria can be spread 2

. Early signs of

infection are water

- soaked translucent irregular to circu lar minute spots on the leaves of the plant. The spots then become necrotic, turning dark brown, and in some cases

coalesce and form large patches that cause the leaves to shed 2 . The bacterium causes branch, stem, and nodal cankers as well as fruit blemishes. Immature fruit burst as a result of bacterial infection, because the pericarp tissues cannot expand during fruitexpansion 1

.

Damage potential of the pest:

Xanthomonas axonopodis pv. p unicae is the causal agent of serious blight disease of

pomegranate 2 . This bacterial pathogen has been recorded as attacking the above ground parts of the plant, including branches, fruits, leaves, nodes, pericarps, and stems, entering the plant via wounds 1,2 . Production losses of 50 to 100% can occur as a result of the blight, depending on the severity of the disease 2 . In India, pomegranate production is described as being seriously hamper ed by the bacterium 1

.

Known host range:

Punica spp. 1

Action under NAPPRA:

The importation of Punica spp. plants for planting , except seed but including cut flowers and greenery , a host of Xanthomonas axonopodis pv. p unicae

, is not authorized pending a pest risk analysis (NAPPRA) from all countries :
