Reliance on adult external morphological characters for identification can be problematic because of wide within-species variability and the need for good-quality specimens. The inability to identify developmental stages can also hamper early-detection programs. Using two character identification systems, genitalic (aedeagus) morphology, and DNA markers (random amplified polymorphic DNA polymerase chain reaction (RAPD-PCR)) to distinguish S. schevyrewi from S. multistriatus, we examined specimens from geographically distinct populations of both species collected from infested host trees or semiochemical-baited funnel traps. We found that aedeagus morphology can be used to identify the two species. The use of two oligonucleotide primers in the RAPD-PCR analysis yielded distinct DNA banding patterns for the two species. Species identification using RAPD-PCR analysis was validated by a blind test and used to make species identifications of larval specimens. These tools improve the ability to differentiate between S. schevyrewi and S. multistriatus at immature and adult stages, and could be developed and used for other scolytines as well.10aScolytus multistriatus10aScolytus schevyrewi1 aJohnson, Patricia, L.1 aHayes, Jane, L.1 aRinehart, John1 aSheppard, Walter, S.1 aSmith, Steven, E.  uhttps://weevil.myspecies.info/characterization-two-non-native-invasive-bark-beetles-scolytus-schevyrewi-and-scolytus-multistriatus02092nas a2200193   4500008004100000020001400041245009100055210006900146260000800215300001200223490000800235520144900243653002801692100001301720700001701733700001901750700001901769856011001788       2012                        eng d  a0008-347X00aAssociation of tree diameter with body size and lipid content of mountain pine beetles0 aAssociation of tree diameter with body size and lipid content of  cJun  a467-4770 v1443 aHost tree diameter is considered an important predictor of the population dynamics of the mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae: Scolytinae), but the relationship between host tree diameter and beetle traits is unclear. The primary objective of this study was to determine how the quality of individual mountain pine beetles, measured as body size (pronotum width) and lipid content, varied with the diameter of lodgepole pine trees, Pinus contorta var. latifolia Engelmann (Pinaceae). Naturally attacked trees, ranging in diameter from 10 to 35 cm, were selected from stands near Prince George, British Columbia, Canada. Colonisation density and pupal density generally increased with tree diameter, but the number of pupal chambers per gallery start remained constant. Tree diameter positively affected beetle body size, which in turn was positively correlated with absolute lipid content in both sexes and relative lipid content in males. However, tree diameter did not directly predict absolute lipid content, and relative lipid content decreased with tree diameter in males. Larger beetles emerged earlier in the emergence period with relative lipid content remaining constant throughout emergence. All relationships had considerable unexplained variation. Thus, the use of tree diameter or emergence time as predictors of population dynamics of mountain pine beetles should be done with caution.10aDendroctonus ponderosae1 aGraf, M.1 aReid, M., L.1 aAukema, B., H.1 aLindgren, B.S.  uhttps://weevil.myspecies.info/association-tree-diameter-body-size-and-lipid-content-mountain-pine-beetles01362nas a2200181   4500008004100000020001400041245004700055210004700102260002100149300001200170490000800182520081900190653002501009100002601034700001901060700002801079856007301107       2007                        eng d  a0008-347X00aNew trap for emergent Megaplatypus mutatus0 aNew trap for emergent Megaplatypus mutatus  cNovember-Decembe  a894-8960 v1393 aMegaplatypus mutatus (= Platypus mutatus) (Chapuis), an ambrosia beetle (Coleoptera: Platypodidae) native to South America, is a forest pest that attacks live standing trees, affecting commercial poplar and other broadleaf plantations. Traditionally, single-chambered emergence traps have been used to collect live beetles for field and laboratory studies. However, the lack of separation in these chambers results in antagonistic interactions between individuals. Wounded M. inutatus are incapable of successful reproduction and are of little value in physiological and behavioral experiments. We introduce a new, multiple-chambered trap that isolates individual insects until collection, thus increasing the number of uninjured and fully functional insects available for physiological and behavioral experiments.10aMegaplatypus mutatus1 aLiguori, Pablo, Gatti1 aZerba, Eduardo1 aAudino, Paola, Gonzalez  uhttps://weevil.myspecies.info/new-trap-emergent-megaplatypus-mutatus02547nas a2200193   4500008004100000020001400041245012000055210006900175260002100244300001200265490000800277520180400285653002402089100002802113700002602141700002802167700002302195856013502218       2007                        eng d  a0008-347X00aThe response of Dendroctonus valens and Temnochila chlorodia to Ips paraconfusus pheromone components and verbenone0 aresponse of Dendroctonus valens and Temnochila chlorodia to Ips   cJanuary-February  a141-1450 v1393 aThe 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 (-)-[beta]-pinene, (+)-3-carene, and (+)-[alpha]-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.

Currently, British Columbia, Canada, is experiencing the largest recorded outbreak of this insect, including areas that historically have had low climatic suitability for it. We analyzed 26 constitutive resin terpenes in phloem samples from British Columbia lodgepole pine (Pinus contorta) populations to test for differential resistance to mountain pine beetle attack, based upon the likelihood of previous exposure to mountain pine beetle. We assessed sampled trees for number of mountain pine beetle attacks, number of pupal chambers, and tree survival the following spring. Significant differences were found when levels of certain terpenes in lodgepole pine populations that had likely experienced substantial mountain pine beetle infestations in the past were compared with those in populations that likely had not experienced large outbreaks of mountain pine beetle. Although we expected southern pine populations to contain more total terpenes than northern populations, owing to higher historical exposure to the beetle, the converse was found. Northern populations generally had higher levels of constitutive terpenes and beetle attack than southern populations. Because several terpenes are kairomones to the mountain pine beetle and also serve as precursors for the synthesis of pheromones, the lower levels of terpenes expressed by lodgepole pines from the historical range of the mountain pine beetle may render them less chemically perceptible to foraging beetles.10aDendroctonus ponderosae1 aClark, Erin, L.1 aCarroll, Allan, L.1 aHuber, Dezene, P.

(Pinaceae)) in the Qin ling Mountains of Shaanxi Province, People's Republic of China. Populations can reach epidemic levels and cause widespread mortality of trees in forest ecosystems. We studied the flight behaviour of D. armandi collected under controlled conditions using a flight-mill system to gather information to aid in its management. Our results indicate that D. armandi has three distinct flight patterns (intermittent flight, short-burst flight, and sustained uninterrupted flight). There were no significant differences in flight performance between males and females. Median daily values for total distance traveled, total flight time, and maximum uninterrupted flight time were 275.1 m day-1, 815 s day-1, 40 s day-1, (n = 148). Individuals displayed positive phototactic behaviour: total flight distance and total flight time were greater under artificial illumination than in natural light or darkness. The level of flight activity increased throughout the morning, remained high during the afternoon (1400-1600), dropped considerably at 1800, and was lowest at midnight. There was no significant difference in flight distance or flight time between the first and second generations. From the data collected, it is clear that the phototactic response is an important factor in the flight behaviour of D. armandi and may influence its spatial dispersal.10aDendroctonus armandi1 aChen, Hui1 aLi, Zhen1 aTang, Ming  uhttps://weevil.myspecies.info/laboratory-evaluation-flight-activity-dendroctonus-armandi-coleoptera-curculionidae-scolytinae00760nas a2200169   4500008004100000020001400041245019900055210006900254260002100323300001200344490000800356653002700364100002500391700002100416700001800437856013500455       2005                        eng d  a0008-347X00aAntennae of Cryptorhynchus lapathi (Coleoptera: Curculionidae) detect two pheromone components of coniferophagous bark beetles in the stems of Salix sitchensis and Salix scouleriana (Salicaceae)0 aAntennae of Cryptorhynchus lapathi Coleoptera Curculionidae dete  cNovember-Decembe  a716-7180 v13710aCryptorhynchus lapathi1 aBroberg, Cynthia, L.1 aBorden, John, H.1 aGries, Regine  uhttps://weevil.myspecies.info/antennae-cryptorhynchus-lapathi-coleoptera-curculionidae-detect-two-pheromone-components-coniferopha01296nas a2200157   4500008004100000020001400041245010700055210006900162260002100231300001200252490000800264520069900272100002000971700002000991856012701011       2007                        eng d  a0008-347X00aResponse of Pityophthorus puberulus (Coleoptera: Curculionidae: Scolytinae) to pheromones and terpenes0 aResponse of Pityophthorus puberulus Coleoptera Curculionidae Sco  cSeptember-Octobe  a742-7470 v1393 aIn field studies conducted to improve trapping programs for the white pine cone beetle, Conophthorus coniperda (Schwarz), a twig beetle, Pityophthorus puberedus (LeConte), a common associate of eastern white pine, Pinus strobus L.

We speculate that limonene may play an important role in host recognition and suitability, by indicating a resource suitable for C. couiperda but unsuitable for P. puberulus.1 aBrauner, A., M.1 ade Groot, Peter  uhttps://weevil.myspecies.info/response-pityophthorus-puberulus-coleoptera-curculionidae-scolytinae-pheromones-and-terpenes02987nas a2200193   4500008004100000020001400041245015600055210006900211260001600280300001200296490000800308520224400316653001302560100002102573700001902594700002302613700002302636856013402659       2009                        eng d  a0008-347X00aAssemblage of Hymenoptera arriving at logs colonized by Ips pini (Coleoptera: Curculionidae: Scolytinae) and its microbial symbionts in western Montana0 aAssemblage of Hymenoptera arriving at logs colonized by Ips pini  cMarch-April  a172-1990 v1413 aColonization of a tree by bark beetles and their symbionts creates a new habitat for a diverse assemblage of arthropods, including competing herbivores, xylophages, fungivores, saprophages, predators, and parasitoids. Understanding these assemblages is important for evaluating, nontarget effects of various management tactics and for subsequently evaluating how changes in climate, the presence of invasive species. and altered forestry practices and land-use tenure may affect biodiversity. We characterized the assemblage of hymenopterans attracted to logs of ponderosa pine (Pinus ponderosa C. Lawson (Pinaceae)) colonized by the bark beetle Ips pini (Say) and its microbial symbionts. In one experiment, the composition and relative abundances, of species arriving at hosts colonized by I. pini, and possible sources of attraction, were determined. Treatments consisted of a loo containing I. pini with its natural complement of microorganisms, a log alone, and a blank control. A second experiment was carried out to determine whether or not Hymenoptera were attracted to microbial symbionts of I. pini. Treatments consisted of a blank control, a to, alone, a lop containing L pini with its natural complement of microrganisms, either Ophiostoma ips, Burk-holderia sp., or Pichia scolyti. and a log inoculated with a combination of these three microorganisms. Over 2 years, 5163 Hymenoptera were captured, of which over 98% were parasitoids. Braconidae, Platygastridae, Encyrtidae. Pteromalidae, and Ichneumonidae were the most abundant. Seven known species of bark beetle parasitoids (all Pteromalidae) were captured. However. parasitoids of Diptera, Lepidoptera, Hymenoptera. and non-wood-boring Coleoptera were also common. Nineteen species showed preferential attraction to host plants infested with I. pini and its complement of microorganisms, host plants inoculated with I. pini microbial symbionts, or host plants alone. Interestingly, many of these species were parasitoids of phytophagous, fungivorous, and saprophytic insects rather than of bark beetles themselves. These results Suggest that a diverse assemblage of natural enemies that attack various feeding guilds within a common habitat exploit common olfactory cues.10aIps pini1 aBoone, Celia, K.1 aSix, Diana, L.1 aKrauth, Steven, J.1 aRaffa, Kenneth, F.  uhttps://weevil.myspecies.info/assemblage-hymenoptera-arriving-logs-colonized-ips-pini-coleoptera-curculionidae-scolytinae-and-its02011nas a2200193   4500008004100000020001400041245005900055210005900114260002100173300001200194490000800206520142000214653002801634100002001662700001901682700001901701700001401720856008301734       2009                        eng d  a0008-347X00aTransport of fungal symbionts by mountain pine beetles0 aTransport of fungal symbionts by mountain pine beetles  cSeptember-Octobe  a503-5140 v1413 aThe perpetuation of symbiotic associations between bark beetles (Coleoptera: Curculionidae: Scolytinae) and ophiostomatoid fungi requires the consistent transport of fungi by successive beetle generations to new host trees. We used scanning electron microscopy and culture methods to investigate fungal transport by the mountain pine beetle (MPB), Dendroctonus ponderosae Hopkins. MPB transports its two main fungal associates, Grosmannia clavigera (Robinson-Jeffrey and Davidson) Zipfel, de Beer and Wingfield and Ophiostoma montium (Rumbold) von Arx, in sac-like mycangia on the maxillary cardines as well as on the exoskeleton. Although spores of both species of fungi were observed oil MPB exoskeletons, often in pits, O. montium spores were generally more abundant than G. clavigera spores. However, a general scarcity of spores of either species on MPB exoskeletons compared with numbers on scolytines that lack sac-like mycangia indicates that fungal transport exteriorly on MPBs is incidental rather than adaptive. Conidia were the dominant spore type transported regardless of location or species; however, Our results Suggest that once acquired in mycangia, conidia may reproduce in a yeast-like form and even produce hypha-like strands and compact conidiophore-like structures. Fungi that propagate in mycangia may provide beetles with a continual source of inocula during the extended egg-laying period.10aDendroctonus ponderosae1 aBleiker, K., P.1 aPotter, S., E.1 aLauzon, C., R.1 aSix, D.L.  uhttps://weevil.myspecies.info/transport-fungal-symbionts-mountain-pine-beetles01024nas a2200157   4500008004100000020001400041245012700055210006900182260001600251300001200267490000800279520040100287653002100688100002200709856013500731       2009                        eng d  a0008-347X00aNon-destructive tree-trunk funnel trap for capturing Hylobius warreni (Coleoptera: Curculionidae) ascending stems of trees0 aNondestructive treetrunk funnel trap for capturing Hylobius warr  cJuly-August  a422-4240 v1413 aA simple and inexpensive non-destructive trap to catch insects as they ascend tree boles is described.

There was no effect of cypress taxon or log category on host selection or attack parameters (attack density, density of systems, density of galleries, rate of successful attacks), although values for C. sempervirens tended to be higher than those for C. arizonica. Reproductive performance (gallery length and fecundity) was highest in C arizonica and lowest in C. sempervirens var. atlantica, with C sempervirens in an intermediate position; egg densities did not differ. Gallery length and fecundity showed a significant linear correlation but were lower in C. sempervirens var. atlantica than in the other two taxa.

More than 18 species of Chalcidoidea (Hymenoptera) were associated with this pest through mass rearings from canola siliques. In southwestern Ontario, the most abundant species were a species of Chlorocytus Graham (23.6%-48.6%), Lyrcus perdubius (Girault) (0%-53%), L. maculatus (Gahan) (2.8%-14.7%), and species of Pteromalus Swederus (0.6%-23.1%) (Pteromalidae). In contrast, the most abundant species in Quebec were Trichomalus lucidus (Walker) (Pteromalidae) (33.3%-56.4%), unidentified Eulophidae (2.1%-39.1%), Mesopolobus gemellus Baur and Muller (Pteromalidae) (1.3%-21.4%), and Necremnus tidius (Walker) (Eulophidae) (11.5%-19.3%). In the Ottawa, Ontario, area, parasitoids were first recovered in 2008, and Trichomalus perfectus (Walker) (Pteromalidae), M. gemellus, and species of Pteromalus were most prevalent. Mesopolobus gemellus and T perfectus are reported in North America for the first time. Although existing communities appear to provide substantial parasitism (e.g., 6.3%-26.3% in 2006), species composition varies among years and differs from that in other regions in North America. Thus, parasitism levels and parasitoid communities of the cabbage seedpod weevil should be monitored to assess whether these will increase or there is a need to introduce more host-specific species from Europe that could provide greater mortality.10aCeutorhynchus obstrictus1 aMason, P., G.1 aMiall, J., H.1 aBouchard, P.1 aGillespie, D., R.1 aBroadbent, A., B.1 aGibson, G., A.

(Coleoptera: Curculionidae). Red alder (Alnus rubra Bong.) (Betulaceae), trembling aspen (Populus tremuloides Michx.), and bigleaf maple (Acer macrophyllum Pursh) (Aceraceae) are not attacked. We studied olfaction and feeding preferences in the laboratory and feeding, oviposition, and emergence in the field. Female C. lapathi preferred Scouler's willow (Salix scouleriana Barratt ex Hook.) over all other species by olfaction, but males did not discriminate between Scouler's willow and black cottonwood or trembling aspen. All species elicited at least some attraction in no-choice situations. Willow was generally preferred for feeding, but black cottonwood and red alder were also acceptable, unlike trembling aspen or bigleaf maple. In field caging experiments, adult weevils emerged from willow, black cottonwood, and red alder. We conclude that olfaction and feeding preferences are sufficiently powerful to mediate the frequent attack observed on native willows, the intermediate levels of attack on cottonwood, and the absence of attack on red alder. Successful development on red alder suggests that C. lapathi could expand its host range to include this species.10aCryptorhynchus lapathi1 aBroberg, Cynthia, L.1 aBorden, John, H.1 aGries, Regine  uhttps://weevil.myspecies.info/olfactory-and-feeding-preferences-cryptorhynchus-lapathi-among-hosts-and-nonhosts02081nas a2200181   4500008004500000020001400045245012400059210006900183260002100252300001200273490000800285520137500293653002701668100002501695700002101720700002301741856013501764       2001                        Engldsh    a0008-347X00aHost range, attack dynamics, and impact of Cryptorhynchus lapathi (Coleoptera: Curculionidae) on Salix (Salicaceae) spp0 aHost range attack dynamics and impact of Cryptorhynchus lapathi   cJanuary-February  a119-1300 v1333 aThe poplar and willow borer, Cryptorhynchus lapathi (L.), known to be present in British Columbia since 1923, primarily attacks species of Salix L. (Salicaceae) and Populus L. (Salicaceae). Larvae bore into stems, causing them to break easily. The impact of the weevil has been rising in recent years because of the increasing importance of poplar and willow from both economic and ecological perspectives. We conducted a study at 45 locations in British Columbia to determine host use among native Salix spp. and the between- and within-tree dynamics of C. lapathi. There were 11 new host records, but the incidence of attack was similar among species. Attacked trees were larger in general and had more dead wood and stems, more adventitious branches per stem, more total breaks per stem, and more naturally caused breaks per stem than their attack-free neighbours. Breaks caused by C. lapathi tended to be slightly larger in diameter and lower on the stem than naturally caused breaks. Bases of stems were preferentially attacked, and C. lapathi selected large stems in which to oviposit. As large attack-free trees become less abundant, weevils apparently start to attack small-diameter stems. Although C. lapathi is adversely affecting the health of willows in British Columbia, there is no evidence that any Salix species is threatened by weevil-caused extinction.10aCryptorhynchus lapathi1 aBroberg, Cynthia, L.1 aBorden, John, H.1 aHumble, Leland, M.  uhttps://weevil.myspecies.info/host-range-attack-dynamics-and-impact-cryptorhynchus-lapathi-coleoptera-curculionidae-salix-salicace00764nas a2200169   4500008004500000020001400045245019900059210006900258260002100327300001200348490000800360653002700368100002500395700002100420700001800441856013500459       2005                        Engldsh    a0008-347X00aAntennae of Cryptorhynchus lapathi (Coleoptera: Curculionidae) detect two pheromone components of coniferophagous bark beetles in the stems of Salix sitchensis and Salix scouleriana (Salicaceae)0 aAntennae of Cryptorhynchus lapathi Coleoptera Curculionidae dete  cNovember-Decembe  a716-7180 v13710aCryptorhynchus lapathi1 aBroberg, Cynthia, L.1 aBorden, John, H.1 aGries, Regine  uhttps://weevil.myspecies.info/antennae-cryptorhynchus-lapathi-coleoptera-curculionidae-detect-two-pheromone-components-coniferopha00498nas a2200109   4500008004100000245011700041210006900158300001200227490000700239100001900246856012300265       1967                        eng d00aA review of the genus Cactopinus, with descriptions of two new species and a new genus (Coleoptera: Scolytidae).0 areview of the genus Cactopinus with descriptions of two new spec  a917-9250 v991 aBright, D., E.  uhttps://weevil.myspecies.info/review-genus-cactopinus-descriptions-two-new-species-and-new-genus-coleoptera-scolytidae00525nas a2200109   4500008004100000245012900041210006900170300001400239490000800253100001900261856013500280       1972                        eng d00aNew species of Scolytidae (Coleoptera) from Mexico, with additional notes: III, Tribe Pityophthorini (except Pityophthorus).0 aNew species of Scolytidae Coleoptera from Mexico with additional  a1665-16790 v1041 aBright, D., E.  uhttps://weevil.myspecies.info/new-species-scolytidae-coleoptera-mexico-additional-notes-iii-tribe-pityophthorini-except-pityophtho
