Published: April 2009

AbstractEight additional adventive aleocharine beetles, native to the Palaearctic region, are reported from Canada, five of them for the first time. They belong to three tribes:Crataraea suturalis(Mannerheim) (Nova Scotia, Saskatchewan, British Columbia) and “Meotica pallens(Redtenbacher)” (Ontario, British Columbia) belong to Oxypodini;Atheta(Chaetida)longicornis(Gravenhorst) (Nova Scotia, Quebec),Atheta(Thinobaena)vestita(Gravenhorst) (New Brunswick),Dalotia coriaria(Kraatz) (Alberta),Dinaraea angustula(Gyllenhal) (Nova Scotia, Prince Edward Island, Quebec, Alberta), andNehemitropia lividipennis(Mannerheim) (New Brunswick, Nova Scotia, Prince Edward Island, Quebec, Ontario) belong to Athetini; andHomalota plana(Gyllenhal) (Nova Scotia, New Brunswick) belongs to Homalotini. These species have likely been introduced into Canada from Europe by various anthropogenic activities, and their bionomics and possible modes of introduction are discussed. For each species, a short diagnosis and habitus and genital images are provided to assist with identification. The habitus and genital images are presented here for the first time for these species in North America. New United States records are not included in the abstract.
Compatibility of Atheta coriaria with other biological control agents and reduced-risk insecticides used in greenhouse floriculture integrated pest management programs for fungus gnats
Authors: Jandricic S. , Scott-Dupree C.D. , Broadbent A.B. , Harris C.R. , Murphy G. 
Published: April 2009

AbstractFungus gnats (FG) (Diptera: Sciaridae: Bradysia spp.) are economically important pests of greenhouse flowers. Larvae feed on root tissue and transmit a variety of phytopathogens. Atheta coriaria (Kraatz) (Coleoptera: Staphylinidae) is a new biological control agent (BCA) for FG. To support its successful use by the greenhouse industry, its compatibility with current integrated pest management (IPM) programs used in floriculture was assessed. This included investigations of prey preference, possible detrimental interactions with other soil-dwelling BCAs, and the toxicity to A. coriaria of registered and novel insecticides. Atheta coriaria showed little preference among eggs of different pest species or between pest eggs and eggs of the intraguild predator Hypoaspis aculeifer (Canestrini) (Acari: Mesostigmata: Laelapidae). It preferred FG 1st-instar larvae to larvae and pupae of other soil-dwelling pests. The entomopathogenic nematode Steinernema feltiae (Filipjev) (Rhabditida: Steinernematidae) was compatible with A. coriaria, but H. aculeifer mites fed on A. coriaria larvae. Insect growth regulators with limited contact activity (e.g., diflubenzuron) were compatible with adult A. coriaria and had minimal effects on larvae compared with other insecticides. Atheta coriaria can be incorporated into an IPM program for FG if harsh insecticides are avoided, but interactions with predatory mites, as well as its effectiveness against other greenhouse pests when FG are present, require further investigation.
The species of Chalcidoidea (Hymenoptera) introduced to North America for biological control of the cabbage seedpod weevil, and the first recovery ofStenomalina gracilis(Chalcidoidea: Pteromalidae)
Authors: Gibson Gary A.P. , Gillespie David R. , Dosdall Lloyd

AbstractThe species of Pteromalidae (Chalcidoidea) introduced to British Columbia, Canada, from Europe in 1949 asTrichomalus fasciatus(Thomson, 1878),Xenocrepis puraMayr, 1904, andHabrocytussp. for classical biological control ofCeutorhynchus obstrictus(Marsham, 1802) (Coleoptera: Curculionidae) are shown to be misidentifications ofTrichomalus perfectus(Walker, 1835),Mesopolobus morys(Walker, 1848), andStenomalina gracilis(Walker, 1834), respectively. Species reared subsequently from seedpods ofBrassicaspp. (Brassicaceae) in British Columbia and reported in the literature under the first three names are shown to be misidentifications of, respectively,Trichomalus lucidus(Walker, 1835),Mesopolobus moryoidesGibson, 2005, and one or both ofPteromalus puparum(L., 1758) andT. lucidus. There is no evidence that eitherT. perfectusorM. morysestablished in North America, butS. gracilisis newly recorded from southern British Columbia based on specimens reared from Brassicaceae seedpods in 2004 and 2005.
Alien true bugs (Hemiptera: Heteroptera) in Canada: composition and adaptations
Authors: Scudder Geoffrey G.E. , Foottit Robert G. 
Published: April 2009

AbstractThe distribution, spread, and adaptations of the 81 alien heteropterous species recorded in Canada are summarized. Sixty-nine species had eastern introductions and 47 had western introductions; 35 were introduced separately on both coasts. Most of the alien species are mirids of European origin. Several of these alien mirids have adapted and become pests of fruit and other agricultural crops, and some have become useful predators. Only 3 have adapted and spread across the whole country.
Ancient temperate rain forest research in British Columbia
Authors: Winchester Neville N. 
Published: April 2009

AbstractThis paper is a tribute to Dr. R.A. Ring upon his retirement. During the past 12 years (1993–2005), an emerging canopy research program has established a wealth of baseline information on the structure and functioning of temperate rain forest canopy arthropod communities. Studies from research sites on Vancouver Island, British Columbia, have shown that ancient temperate rain forest canopy ecosystems contain a largely undescribed fauna that is specific to habitat features found only in these canopies. In particular, diverse assemblages of free-living mites have been shown to dominate conifer species and canopy microhabitats. For example, oribatid mites are the dominant arthropod fauna on branches, branches with attached lichens, and suspended soil accumulations. Species composition differs significantly between the ground and the canopy at both the family and the species level. Arboreal specificity may be due to intrinsic variation in habitat quality, habitat architecture, patchiness, and (or) resource availability. The prevalent patterns of habitat specialization, low vagility, and restricted distribution displayed by a large percentage of the resident canopy microarthropods are features often associated with forest ecoregions that have enjoyed relatively stable conditions for long periods of time, as have the ancient forests on Vancouver Island. Investigators in the “one-Ring lab” continue to document the diversity and abundance of canopy arthropods of temperate forests in British Columbia. In particular, studies are concerned with defining the organizing principles that elicit community patterns associated with the various levels of complexity in arboreal communities. Our long-term goal is to provide a greater degree of predictability when addressing temperate forest diversity issues. To meet the stated goals of sustainable forest management and retention of biodiversity, an extensive plan of ecological research that features arthropods is needed. This plan, fostered by Dr. Ring, should have as a priority the inventory and cataloguing of species assemblages and should address dynamic processes such as organismal dispersal and the effects of habitat loss and fragmentation on arthropods in ancient forests.
Overwintering adaptations in Arctic sawflies (Hymenoptera: Tenthredinidae) and their parasitoids: cold tolerance
Authors: Humble Leland M. 
Published: April 2009

AbstractAlthough the extreme winter conditions of Arctic habitats are considered to be important determinants of the faunal composition of Arctic regions, the overwintering biology of most Arctic insects is unknown. A significant proportion of the insect fauna at high latitudes are hymenopterans, yet little information is available on their overwintering strategies. In this study I examined the overwintering strategies of willow gall-forming and catkin-feeding nematine sawflies and their parasitoids. All sawfly species overwintered as prepupae, were freezing-tolerant, and survived exposure to −50 °C. Freezing at high subzero temperatures was initiated by ice nucleators associated with the posterior hind gut wall. Heterogeneity of overwintering habitats with respect to temperature was not a determinant of the overwintering success of these Arctic sawflies. Divergent overwintering mechanisms were evident in the sawfly parasitoid taxa. Endoparasitoid larvae, like their sawfly hosts, were freezing-tolerant. Freezing of immature, feeding endoparasitoid larvae occurred at the freezing point of the host prepupa and was a consequence of the inoculation of the endoparasitoids' fluid compartments by ice crystals growing in the host hemolymph. Peculiarities in the structure of the endoparasitoid larval gut suggest that the site of nucleation is across the gut wall. Outside their hosts, however, endoparasitoid larvae can supercool extensively, and their tolerance of extremely low temperatures is similar to that of their hosts. Overwintering strategies adopted by the ectoparasitoids were also diverse, with both freezing-tolerant and freezing-intolerant species present in the parasitoid community. Freezing-intolerant species could not survive winter temperatures in the field in the absence of an insulating layer of snow.

Life history of Lygus keltoni (Hemiptera: Miridae) in the laboratory
Authors: Cárcamo H.A. , Larson T.R. , Herle C.E. , Otani J.K. 
Published: April 2009

AbstractLygus keltoni Schwartz and Foottit is a species of plant bugs recently recognized as distinct from L. shulli Knight and an important component of the pest complex that attacks a number of field crops such as canola (Brassica napus) and alfalfa (Medicago sativa) in western Canada. The current laboratory study was undertaken to determine basic life-history parameters, such as instar duration, adult longevity, and reproductive potential, required to develop biologically based pest management strategies. At 25–27 °C, males lived around 34 days and females lived around 48 days. Females produced an average of 133 nymphs but up to 306 nymphs during their reproductive life, which averaged around 4 weeks (7-day preoviposition period). Egg incubation lasted around 10 days, instars 1–4 lasted 2–3 days each, and the 5th instar lasted 4 days. The reproductive potential of L. keltoni seems to be lower than that of L. hesperus Knight and L. lineolaris (Palisot de Beauvois), but other life-history parameters of the adults and development times of the nymphs are comparable.

Published: April 2009

AbstractWe analyzed the phylogenetic relationships between eight Aphidius Nees and six Lysaphidus Smith species on the basis of 12 morphological characters by parsimony analysis. The consensus tree does not support the generic status of Lysaphidus. Aphidius iranicus, sp. nov., associated with Titanosiphon bellicosum Nevsky on Artemisia absinthium L. from Iran, is described. The new parasitoid species is described and illustrated by line drawings, and its diagnostic characters are discussed. The taxonomic position of the subgenus Tremblayia Tizado and Núñez-Pérez is also considered. Tremblayia and Lysaphidus are newly classified as synonyms of Aphidius. The following new or revised combinations are proposed: Aphidius adelocarinus Smith, comb. rev., A. ramythirus Smith, comb. rev., A. rosaphidis Smith, comb. rev., A. viaticus (Sedlag), comb. nov., A. arvensis (Starý), comb. nov., and A. erysimi (Starý), comb. nov.

Introduced Carabidae (Coleoptera) from Nova Scotia and Prince Edward Island: new records and ecological perspectives
Authors: Majka Christopher G. , Cook Joyce , Westby Susan 
Published: April 2009

AbstractSeven species of introduced Carabidae are newly reported in Nova Scotia and Prince Edward Island. Trechus quadristriatus (Schrank), Amara ovata (Fabricius), and Harpalus rubripes (Duftschmid) are newly recorded in Atlantic Canada as a whole. Possible modes of introduction of these species to the region are discussed. Several may have been introduced in association with dry ballast shipments. Some may have arrived via natural dispersion from neighbouring areas; others appear to have been present and undetected for a considerable time. The possible impact of such introductions is also discussed. Synanthropic environments have higher proportions of introduced species than relatively undisturbed, native habitats. Some adventive species do become widespread in native environments; however, negative impacts on native species may not be readily apparent.
Revised higher classification of the Noctuoidea (Lepidoptera)
Authors: Lafontaine J. Donald , Fibiger Michael 
Published: April 2009

AbstractThe higher classification of the families of the Noctuoidea with a quadrifid forewing (Nolidae, Strepsimanidae, Arctiidae, Lymantriidae, Erebidae, and Noctuidae) is reviewed from the perspective of recent classifications and the distribution of derived character states. On the basis of recent morphological and molecular studies, we propose a more inclusive definition of the family Noctuidae that adds the subfamilies Nolinae, Strepsimaninae, Arctiinae, Lymantriinae, and Erebinae to the subfamilies more traditionally included in the Noctuidae. Consequently, the superfamily Noctuoidea comprises the families Oenosandridae, Doidae, Notodontidae, Micronoctuidae, and Noctuidae. The tribe Cosmiini, currently in the subfamily Xyleninae, is downgraded to the status of subtribe Cosmiina and placed in the tribe Xylenini. The tribe Balsini, currently in the subfamily Xyleninae, is elevated to the status of subfamily Balsinae. The tribe Phosphilini is transferred from the subfamily Psaphidinae to the Xyleninae.
The response of Dendroctonus valens and Temnochila chlorodia to Ips paraconfusus pheromone components and verbenone

Published: April 2009

AbstractThe red turpentine beetle, Dendroctonus valens LeConte, 1860 (Coleoptera: Curculionidae, Scolytinae), is a common bark beetle found throughout much of North America and China. In 2004, we observed that attack densities of the California fivespined ips, Ips paraconfusus Lanier, 1970 (Coleoptera: Curculionidae, Scolytinae), in logging debris were inversely related to D. valens attacks on freshly cut stumps, which led to the demonstration that components of the aggregation pheromone of I. paraconfusus inhibited the response of D. valens to attractant-baited traps. In this study, we test the response of D. valens and Temnochila chlorodia (Mannerheim, 1843) (Coleoptera: Trogositidae), a common bark beetle predator, to racemic ipsenol, racemic ipsdienol, and (−)-cis-verbenol (IPSR) in the presence and absence of two release rates of (−)-verbenone. The addition of a relatively low release rate of (−)-verbenone (4 mg/24 h) to attractant-baited traps did not affect catch and had no significant effect on the response of D. valens to IPSR. IPSR significantly reduced D. valens attraction to baited traps. The addition of high release rates of (−)-verbenone (50 mg/24 h) to IPSR significantly increased inhibition; however, the effect was not significantly different from that observed with (−)-verbenone alone (50 mg/24 h). Temnochila chlorodia was attracted to traps baited with (−)-β-pinene, (+)-3-carene, and (+)-α-pinene. The addition of (−)-verbenone (50 mg/24 h) significantly increased attraction. Traps baited with IPSR caught significantly more T. chlorodia than those baited with (−)-verbenone. Few other beetles were collected. We are hopeful that these results will help facilitate the development of an effective tool for protecting Pinus spp. from D. valens infestations.
The weevils (Coleoptera: Curculionoidea) of the Maritime Provinces of Canada, II: New records from Nova Scotia and Prince Edward Island and regional zoogeography

Published: April 2009

AbstractSeventy-nine species of weevils are newly reported in Nova Scotia and 66 species are newly reported on Prince Edward Island, increasing the known provincial weevil faunas to 244 and 92 species, respectively. Thirty-six species are recorded for the first time in the Maritime Provinces; of these,Ceutorhynchus pallidactylus(Marsham),Listronotus dietziO'Brien,Corthylus columbianusHopkins, andOrchidophilus aterrimus(Waterhouse) are recorded for the first time in Canada.Orchidophilus aterrimushas been collected only in exotic domesticated orchids and is not established in the wild. Fourteen species previously recorded on Cape Breton Island, Nova Scotia, are reported from the provincial mainland. Four species —Curculio sulcatulus(Casey),Ceutorhynchus squamatusLeConte,Tachyerges niger(Horn), andIps calligraphus(Germar) — are removed from the faunal list of Nova Scotia, and three species —Temnocerus cyanellus(LeConte),Curculio nasicus(Say), andCryphalus ruficollis ruficollisHopkins — are removed from the faunal list of Prince Edward Island. The combined known weevil fauna of the Maritime Provinces now totals 290 species. The adequacy of collection effort is discussed and in Nova Scotia, where collection effort has been greatest, distribution patterns of selected groups of species are examined. Island faunas are discussed with respect to those of Prince Edward Island and Cape Breton Island. Regional biogeographic patterns of species are also discussed, including possible disjunct populations in Nova Scotia and species that may not have crossed the isthmus of Chignecto to colonize Nova Scotia. Attention is drawn to the long history of introduced species in the region and to ongoing introductions through an examination of the earliest records for the 60 introduced species found in the region.

Biology of the spiny ash sawfly, Eupareophora parca (Hymenoptera: Tenthredinidae: Blennocampinae), in Edmonton, Alberta
Authors: Williams Daryl J. 
Published: April 2009

AbstractThe spiny ash sawfly, Eupareophora parca (Cresson, 1880), was discovered in Edmonton in 2003 at the Northern Forestry Centre defoliating planted ash trees (Fraxinus spp.). This represents the first record of this species from Alberta. Observations of adult and larval behaviour and life-history variables such as adult flight, number and duration of larval instars, and overwintering were made. The nature and severity of defoliation was monitored in 2003 and 2004, and large increases were detected in the amount of defoliation per site and the number of sites defoliated between years. The precipitous increase in severity and extent of defoliation indicates the possibility that this species could become a significant urban pest in the province.
