AbstractThe angiosperm bark volatile, conophthorin, was tested at release rates of 3.0 and 0.3 mg/24 h against the Douglas-fir beetle, Dendroctonus pseudotsugae Hopkins, the spruce beetle, Dendroctonus rufipennis (Kirby), the pine engraver, Ips pint (Say), and the western balsam bark beetle, Dryocoetes confusus Swaine (all Coleoptera: Scolytidae). The responses of D. pseudotsugae, I. pini, and (in one of two experiments) female D. confusus to attractant-baited traps were disrupted by conophthorin in a dose-dependent manner. Dendroctonus rufipennis was not disrupted by conophthorin. Our results extend the repellent bioactivity of conophthorin to Ips DeGeer spp. and confirm earlier experiments with D. pseudotsugae. Conophthorin may have some utility in protecting susceptible timber from bark beetle attack.

Temnochila Chlorodia

Bark beetles (Coleoptera: Scolytidae) are commonly recognized as the most important mortality agent in western coniferous forests. In this study, we describe the abundance of bark beetle predators collected in multiple-funnel traps baited with exo-brevicomin, frontalin and myrcene in northern California during 2003 and 2004. A total of 32,903 Temnochila chlorodia (Mannerheim), 79 Enoclerus lecontei (Wolcott), and 12 E. sphegeus (F.) were collected. The seasonal abundance of E. lecontei and E. sphegeus was not analyzed because too few individuals were collected. In general, T. chlorodia was most abundant in late spring, but a second smaller peak in activity was observed in late summmer. Overall, the ratio of males to females was 0.82. A significant temporal effect was observed in regard to sex ratios with more males collected during later sample periods. Temnochila chlorodia flight activity patterns were similar between years, but activity was generally delayed several weeks in 2003.

Pheromone-baited traps are frequently used for research or in monitoring populations of bark beetles such as the southern pine beetle, Dendroctonus frontalis Zimmermann, and Ips spp. which are important pests of southern pines. We compared the effectiveness of two commercially available trap designs, the multiple-funnel trap and the slot trap, for collection of D. frontalis, three species of Ips, and two of their common predators. Slot traps captured greater numbers of bark beetles while multiple-funnel traps captured more predators. Multiple-funnel traps were judged to be easier to transport and check in the field. This study indicates that slot traps are preferable for monitoring southern bark beetles with the least disruption to natural enemy populations, while multiple-funnel traps are better for monitoring bark beetle/predator ratios. Due to ease of checking and handling, multiple-funnel traps are preferable for uses that involve large numbers of traps, long-distance manual hauling, or frequent relocation of traps.
