Moths trapped in Alaska with feeding attractant lures and the seasonal flight patterns of potential agricultural pests
Authors: Landolt Peter J. , Pantoja Alberto , Hagerty Aaron , Crabo Lars , Green Daryl 
Published: April 2009

AbstractTraps baited with two types of chemical feeding attractants yielded 97 species of macrolepidoptera at three areas in Alaska (Fairbanks, Delta Junction, and Palmer). These were 16 geometrid, 1 thyatirid, and 76 noctuid moth species and 4 species of nymphalid butterflies. Potential crop pests trapped included Apamea devastator (Brace) (glassy cutworm), Xestia c-nigrum L. (spotted cutworm), Xestia smithii (Snellen) (Smith's dart), Euxoa ochrogaster (Guenée) (redbacked cutworm), and Discestra trifolii (Hufnagel) (clover cutworm). The clover cutworm was captured early in the season (May into June), while Smith's dart, glassy cutworm, spotted cutworm, and redbacked cutworm were captured in traps in mid to late summer. Many more species and greater numbers of moths were captured in traps baited with acetic acid and 3-methyl-1-butanol than in traps baited with a multicomponent floral lure (phenylacetaldehyde, methyl salicylate, methyl-2-methoxy benzoate, and β-myrcene). However, most of the geometrid moths captured (12 of 16 species) were in floral lure traps, while one species of Hadeninae (Noctuidae) and both species of Plusiinae (Noctuidae) were trapped exclusively in floral lure traps. The one thyatirid, both Catocalinae noctuid species, and most Amphipyrinae, Cuculliinae, Hadeninae, and Noctuinae noctuid species were captured in traps baited with acetic acid and 3-methyl-1-butanol. In addition, large numbers of bumblebees were captured in traps baited with the floral lure, while large numbers of yellowjackets were captured in traps baited with acetic acid and 3-methyl-1-butanol.
Attraction of male Mayetiola thujae (Diptera: Cecidomyiidae) to the sex-pheromone blend of (2S,12S)-, (2S,13S)-, and (2S,14S)-diacetoxyheptadecane is reduced in the presence of the SR- or RR-stereoisomers

AbstractIn a field trapping experiment in an abandoned seed orchard of western red-cedar, Thuja plicata Donn × D. Don, in British Columbia, we show that attraction of male red-cedar cone midges, Mayetiola thujae (Hedlin), to the pheromone blend (2S,12S)-, (2S,13S)-, and (2S,14S)-diacetoxyheptadecane is reduced in the presence of a blend of all other stereoisomers, or of the three SR- or RR-stereoisomers. The three RS-stereoisomers, in contrast, had no significant effect. Thus, synthetic pheromone for monitoring M. thujae populations must not contain the SR- or RR-stereoisomers of 2,12-, 2,13-, and 2,14-diacetoxyheptadecane. This result will allow development of a less expensive design for synthesizing the pheromone.

AbstractThe acute toxicities of an extract obtained from a plant within the Piperaceae family and related synthetic analogues were tested against four common Canadian forest pest insects. The acute toxicity of the extract from black pepper, Piper nigrum L., was assessed after 1, 24, and 72 h by the percent larval mortality. The 24 h LC50 estimates for the P. nigrum extract were (in order of decreasing sensitivity) 0.012% for the introduced pine sawfly, Diprion similis (Hartig) (Hymenoptera: Diprionidae), 0.053% for the forest tent caterpillar, Malacosoma disstria Hubner (Lepidoptera: Lasiocampidae), 0.282% for the gypsy moth, Lymantria dispar (L.) (Lepidoptera: Lymantriidae), and 0.998% for the spruce budworm, Choristoneura fumiferana (Clemens) (Lepidoptera: Torticidae). There was no significant increase in mortality after 72 h. Seventy percent of L. dispar larvae dropped off or moved from branches within 1 h of application of 0.2% P. nigrum extract, indicating that these compounds have a repellent effect. Pipercide and nor-pipercide were more toxic to L. dispar and M. disstria larvae than piperolein A and a P. sarmentosum Roxb. amide 72 h after either oral or topical administration of these compounds. Toxic effects of piperamides were more pronounced by oral ingestion. Ninety percent mortality of L. dispar larvae occurred following an oral dose of 5 µg pipercide in diet, whereas mortality was only 40% following topical treatment at 5 µg pipercide/insect. Whole Piper extracts might be useful for the control of sawflies and tent caterpillars in small-scale applications, based on the demonstrated efficacy and reduced risk potential.

Authors: Handfield Daniel , Handfield Louis 
Published: April 2009

AbstractA new species of the genus Plusia Ochsenheimer is described from North America on the basis of differences in wing colour, markings, and genital structure. The new species, typically found in bogs, was first recognized through molecular sampling for the Barcode of Life Initiative and differs significantly from other species of Plusia in the cytochrome c oxydase I (COI) mitochondrial gene sequence.

Published: April 2009

AbstractThe bark weevil,Pissodes yunnanensisLangor and Zhang, is an important pest of young Yunnan pine,Pinus yunnanensisFranchet (Pinaceae), in southwestern China. Populations of the host and weevil are disjunct, especially in the northwestern part of the range in Yunnan province. To estimate maternal gene flow and examine the genetic structure ofPissodes yunnanensis, we sequenced an 840-bp fragment of the mitochondrial cytochromecoxidase I (COI) gene in 60 individuals from 7 populations in Yunnan and Guizhou provinces. Percent divergence among populations ranged from 0.001% to 2.1%. Nested clade analysis of 21 haplo types showed evidence of genetic structuring that is inferred to be primarily due to allopatric fragmentation and a low level of gene flow. Analysis of molecular variance also showed significant genetic structuring and restricted gene flow among weevil populations, especially between northwestern and eastern regions of the range. Such genetic structuring may be important for pest management programs. Phylogenetic analyses comparing the same 761-bp sequence amongP. yunnanensis, Pissodes punctatusLangor and Zhang from southwestern China, and five Nearctic species ofPissodesshowed that (i) the two Chinese species were most closely related to each other, (ii) the four species in theP. strobi(Peck) species group formed a distinct clade, and (iii) these two clades were more similar to each other than to the Nearctic speciesP. affinisRandall.
A revision of the North American species of Brachylomia (Lepidoptera: Noctuidae: Xyleninae) with descriptions of four new species
Authors: Troubridge James T. , Lafontaine J. Donald 
Published: April 2009

AbstractThe North American species of Brachylomia Hampson, 1906 are revised and four new species (B. cascadiasp. nov., B. obscurifasciasp. nov., B. pallidasp. nov., and B. sierrasp. nov.) are described. The monotypic genus Lomilysis Franclemont, 1937 is synonymized with Brachylomia. Epunda onychina Guenée, 1852, which is currently placed in Brachylomia, is reclassified as a senior synonym of Egira alternans (Walker, [1857]), but Epunda onychina, not being associated with any known species in more than 150 years, is treated as a nomen oblitum, so Egira alternans is a nomen protectum under provisions of Article 23.9.2 of the International Code of Zoological Nomenclature. Adults and genitalia of Nearctic species of Brachylomia are figured.

Authors: Castro Dolores del Carmen , Cicchino Armando 
Published: April 2009

AbstractThis study deals with two species of the genus Phtheiropoios, redescribing P. tucumanus Cicchino, 1990, previously known from five specimens collected on Ctenomys tucumanus Thomas, 1900, and describing P. inaequalissp. nov. from C. tuconax Thomas, 1925, both from different localities in Tucumán Province, Argentina. Diagnostic features for the new species include proportion of the male forficula, male external genitalia, and counts of setae and body measurements in both sexes. Brief comments on the morphological affinities of these species with other species of Phtheiropoios, and a key to males of all species of the genus Phtheiropoios known to parasitize rodents of the genus Ctenomys, are included.
The elements of seasonal adaptations in insects
Authors: Danks H.V. 
Published: April 2009

AbstractThe many components of seasonal adaptations in insects are reviewed, especially from the viewpoint of aspects that must be studied in order to understand the structure and purposes of the adaptations. Component responses include dispersal, habitat selection, habitat modification, resistance to cold, dryness, and food limitation, trade-offs, diapause, modifications of developmental rate, sensitivity to environmental signals, life-cycle patterns including multiple alternatives in one species, and types of variation in phenology and development. Spatial, temporal, and resource elements of the environment are also reviewed, as are environmental signals, supporting the conclusion that further understanding of all of these seasonal responses requires detailed simultaneous study of the natural environments that drive the patterns of response.

Authors: Majka Christopher G. , McCorquodale David B. , Smith Mary E. 
Published: April 2009

AbstractThe long-horned beetles (Cerambycidae) of Prince Edward Island are surveyed. Records of 28 species of cerambycids new to the province are provided, increasing the known fauna of this family on the island to 38 species. One species,Pogonocherus penicillatusLeConte, is removed from the list of the province's fauna. Additionally, one exotic species,Rhopalophora tenuis(Chevrolat), is reported as intercepted from merchandise imported from Mexico. This fauna is examined in relation to its distribution within the province, biogeographical components, island biogeography, the composition of the regional fauna, the impact of anthropogenic activities, and adventive species. All these provide lessons to improve our understanding of the biodiversity of the province.
Effects of an azinphos-methyl runoff event on macroinvertebrates in the Wilmot River, Prince Edward Island, Canada
Authors: Purcell Lisa A. , Giberson Donna J. 
Published: April 2009

AbstractHigh levels of azinphos-methyl (0.4–0.8 µg/L) were detected in the Wilmot River, Prince Edward Island, Canada, following runoff from an agricultural field after a heavy rainfall on 19 July 2002. Benthic macroinvertebrate abundance and diversity were sharply lower in samples collected 1 d after the event compared with samples collected in the same manner in July or October 2001. The greatest effects were noticed on the aquatic insects, whose abundance declined from >10 000 individuals per 3-min kick sample in July 2001 to <900 individuals per 3-min kick sample in July 2002. One family of Diptera, one family of Plecoptera, and three families of Trichoptera disappeared entirely from the study reach after the runoff event, and several other families were severely depleted in number. This led to low taxonomic similarity values between the communities before and after the runoff event and a change relative to reference streams on PEI. Examination of biological metrics (including indices such as % EPT (Ephemeroptera, Plecoptera, or Trichoptera), % chironomids, % burrowers, etc.) confirmed that aquatic insects were more heavily targeted by the insecticide than non-insect invertebrates. This resulted in a shift in the community towards non-insect taxa that were better able to avoid or tolerate this type of pollution.

Authors: Moya-Raygoza Gustavo 
Published: April 2009

AbstractNative parasitoids of the adult Mexican corn leafhopper,Dalbulus elimatus(Ball), and corn leafhopper,Dalbulus maidis(Delong and Wolcott), are described and their rates of parasitism on maize,Zea maysL., common barley,Hordeum vulgareL., and sorghum,Sorghumbicolor(L.) Moench (Poaceae) in central Mexico are determined. The survey was conducted throughout an annual cycle, with sampling of the previous season's crops when they were available. Leafhoppers showing evidence of parasitism were reared individually in the laboratory to obtain adult parasitoids. AdultD. elimatuswere parasitized on winter maize, barley, and sorghum by the flyEudorylas subopacus(Loew) (Diptera: Pipunculidae) and the waspGonatopus bartlettiOlmi (Hymenoptera: Dryinidae), whereas adultD. maidiswere parasitized by these fly and wasp parasitoids on winter maize only. The highest rates of parasitism ofD. elimatusbyE. subopacuswere 57.4% on maize, 39.6% on barley, and 48.8% on sorghum. The highest rate of parasitism ofD. maidisbyE. subopacuswas 20.4% on maize. In contrast, the highest rates of parasitism ofD. elimatusbyG. bartlettiwere 9.4% on maize, 2.7% on barley, and 25.8% on sorghum. The highest rate of parasitism ofD. maidisbyG. bartlettiwas 7.1% on maize. These results indicate that winter crops are habitats ofE. subopacusandG. bartlettiduring the winter season. This is the first report ofD. elimatusandD. maidisbeing parasitized byE. subopacusand ofD. elimatusbeing parasitized byG. bartletti.
Predicting the seasonal development of the yellowheaded spruce sawfly (Hymenoptera: Tenthredinidae) in eastern Canada
Authors: Régnière Jacques , Lavigne Dan , Dupont Alain , Carter Nelson 
Published: April 2009

AbstractDegree-day phenology models for the yellowheaded spruce sawfly,Pikonema alaskensis(Rohwer), were developed from data sets collected in infested plantations of black spruce,Picea mariana(Mill.), and white spruce,P. glauca(Moench) Voss, in New Brunswick and Quebec, Canada, between 1995 and 1999. The models describe the relationships between degree-day accumulation (above −1 °C, from 1 April) and cumulative adult emergence, capture in pheromone traps, the dates of appearance of first adult, egg, and larva, and the relative frequency of successive larval stages. The models predict adult emergence with a precision of ±2 days and male catch in pheromone traps with a precision of ±1.6 days. The first adult, first egg, and first larva occurred after 527 ± 42, 660 ± 52, and 725 ± 18 degree-days above –1 °C, respectively, and the dates of these events are predicted within ±1.8 days. The dates of 50% occurrence of the successive instars are predicted within 4.5 days of observed dates, and the date of peak 2nd instar is predicted within ±3.6 days.

Published: April 2009

AbstractRove beetle assemblages from forest dominated by yellow birch (Betula alleghaniensis Britt. (Betulaceae)) at two sites in southeastern Quebec were characterized in terms of composition, diversity, and relative abundance. In total, 143 species were collected over two seasons (June–August of 1999 and 2000). In the pretreatment year (1999), 88 species were found in uncut stands. In the post-treatment year, 116 species were found in treated (by patch harvesting and ground scarification) and control plots combined. Sixty-one species were common to the two sites, 27 species captured in the 1999 season were not recaptured in the 2000 season, and 55 additional species were captured in 2000. There are 23 new distribution records for Quebec, and one species, Atheta (Dimetrota) pseudomodesta Klimaszewski, sp. nov., is described. New bionomics data on relative abundance, seasonality, and the utility of different trapping methods are presented. Assemblage composition is compared with that of a red spruce (Picea rubens Sarg. (Pinaceae)) forest in New Brunswick.
Review of the species of Trichomalus (Chalcidoidea: Pteromalidae) associated with Ceutorhynchus (Coleoptera: Curculionidae) host species of European origin

Published: April 2009

AbstractSix species of Trichomalus Thomson were reared as parasitoids of Ceutorhynchinae hosts in Europe during surveys in 2000–2004. Trichomalus rusticus (Walker) is treated as a valid species, resurrected from synonymy under T. lucidus (Walker), and T. lyttus (Walker) is transferred from synonymy under T. lucidus and newly placed in synonymy with T. rusticus. Illustrated keys to females and males are given to differentiate the six species (T. bracteatus (Walker), T. campestris (Walker), T. gynetelus (Walker), T. lucidus, T. perfectus (Walker), and T. rusticus) except for males of T. bracteatus and T. gynetelus. A lectotype female is designated for T. rusticus. Trichomalus campestris is newly recorded as a parasitoid of Ceutorhynchus cardariae Korotyaev. Implications of the host-parasitoid associations recovered by the surveys are discussed relative to introduction of species to North America for classical biological control.

It is distinguished from its congeners by its granular integument, body mostly lacking hairlike setae, cerci with a row of spiniform setae along the lateroexternal margins, and dorsomedial margin of female epiproct with a row of spiniform setae. It does not particularly resemble any other larva ofAeshnaor related genera described to date. The larval habitat is described for the first time.
Global review of some Anthroleucosomatidae (Diplopoda: Chordeumatida) with description of a new millipede genus from the Balkan Peninsula
Authors: Ćurčić B.P.M. , Makarov S.E. , Tomić V.T. , Mitić B.M. 
Published: April 2009

AbstractThe millipede Perunosoma trojanicagen. nov., sp. nov. is described on the basis of specimens from the Prekonoška Pećina Cave in southeast Serbia. Scanning electron micrographs of the gonopods and legs are presented. Comparative photomicrographs of the closely related genus Serbosoma Ćurčić and Makarov, 2000 are also presented. The central part of the anterior gonopods in these genera can be species-specific and provide grounds for initial recognition of species. The Anthroleucosomatidae occupy three disjunct areas globally: one on the west coast of North America, the second in Asia, and the third in Europe. The North American anthroleucosomatid fauna is composed of one monotypic genus, while the Asian one includes six genera with seven species and the much more diverse European anthroleucosomatids include 14 genera with 39 species.
Repeatability of sperm size in outbred and inbred Scathophaga stercoraria (Diptera: Scathophagidae)
Authors: Bernasconi G. , Ward P.I. , Hellriegel B. 
Published: April 2009

AbstractVariability in male gametic traits can depend on several genetic and environmental factors such as developmental instability as a consequence of inbreeding, developmental noise during spermatogenesis, or age- or condition-dependent changes in allocation to sperm cells. Variation in sperm size is particularly evident in species that produce more than one sperm morph but also occurs among males in sperm-monomorphic species. Both discrete and continuous sperm size variation have been implicated in male fertilization success when the sperm of several males directly compete for fertilization of the same set of ova. In this study, we investigated among-male variation in sperm length in field-collected, outbred male Scathophaga stercoraria (L.) flies, as well as in flies from the same natural population that had been subjected to 15 and 16 generations of inbreeding under laboratory conditions. Among-male variation in sperm length was significant and repeatable over subsequent matings in both inbred and outbred flies. We conclude that sperm length can be used as an individual male marker in sperm competition studies and that significant repeatability of sperm length supports heritability for this trait.

Published: April 2009

AbstractBrassicaceae germplasm (Brassica napusL.,Brassica rapaL.,Brassica juncea(L.) Czern.,Brassica carinataA. Braun,Sinapis albaL.,Camelina sativa(L.) Crantz,Crambespecies) with cultivar development potential for the prairies was evaluated for resistance to cabbage seedpod weevil (Ceutorhynchus obstrictus(Marsham) (Coleoptera: Curculionidae)) infestation under field conditions in southern Alberta from 2001 to 2005. Relative susceptibilities were as follows:B. rapaandB. napus>B. juncea=B. carinata>S. alba. Although some of the germplasm evaluated varied within species in terms of glucosinolate profile, erucic acid level, oil content, and plant height, none of these factors appeared to influence the degree ofC. obstrictusdamage. A subset of this germplasm was also evaluated in the greenhouse. Although the canola speciesB. rapasustained the highest level of damage in the field tests, it was similar to otherBrassicagenotypes in the greenhouse. All lines ofS. albawere virtually immune to weevil attack in both field and greenhouse tests, regardless of glucosinolate profile, suggesting that other factors confer resistance in this species. Synchrony of crop development with weevil activity in the field explains some of the variability in damage observed among genotypes and illustrates the importance of combining field and greenhouse studies when assessing resistance.
