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.},

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.},

	abstract = {The 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.},

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.},

	abstract = {Colonization 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.},

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.},

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.},

	abstract = {In British Columbia, native willows (Salix spp.) (Salicaceae) and, to a lesser extent, black cottonwood (Populus trichocarpa Torr. \& Gray) (Salicaceae) are frequently attacked by the poplar and willow borer, Cryptorhynchus lapathi (L.) (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{\textquoteright}s willow (Salix scouleriana Barratt ex Hook.) over all other species by olfaction, but males did not discriminate between Scouler{\textquoteright}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.},

	abstract = {The 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.},
