Interpretive Summary: The brown marmorated stink bug, Halyomorpha halys (Stal), is an invasive species that has become a serious pest of tree fruit crops. Growers require trapping tools that allow them to monitor the presence, abundance, and seasonal activity of this destructive species. Through a series of trials, we found that commercially available lures used in association with black pyramid traps appeared to rapidly decline in attractiveness after just a few days. We also found that kill strips used to retain bugs in collection jars were effective at over a four-week period. However, questions regarding efficacy of collection jars remain, particularly with regard to overall jar design, best location of lure, and need for ventilation of jar to distribute plumes released by lures to attract bugs. We will be conducting more experiments to establish the best location for lure deployments associated with traps and effective capture and retention mechanisms for collection jars for brown marmorated stink bug.

Technical Abstract: Trapping experiments targeting brown marmorated stink bug, Halyomorpha halys (Stal,) addressed the effects of; 1) a modification to the trap container of a commercial trap, 2) the age of methyl (2E,4E,6Z)-decatrienoate lures, and 3) the age of dichlorvos-impregnated kill strips on bug captures. In the trap modification study, ventilation holes in the containers atop standard, commercial AgBio traps were modified to resemble a USDA prototype trap, and captures were compared among the standard and modified commercial traps, and prototype traps. H. halys captures were significantly greater in the prototype trap than in standard commercial traps, while captures in modified commercial traps were intermediate between but not significantly different from AgBio or prototype traps. Traps baited with kill strips that were fresh or that had been field-aged for 1, 2, 3 or 4 weeks showed no significant differences in the total number of H. halys captured over a 15 day trapping interval, although the percentage of dead bugs was significantly greater in traps containing fresh lures than in those with 3- or 4-week-old lures. In the aged lure experiment, captures were not significantly different among traps baited with fresh, 1- and 2-week-old lures or among those baited with 2-, 3- or 4-week old lures or unbaited. Most (64.8 percent) bugs were caught during the first 3 day sample interval, during which traps with fresh lures captured more H. halys than those with each aged lure treatment. Weekly gravimetric measurements to determine the release of methyl (2E,4E,6Z)-decatrienoate from lures over 4 wk showed a sharp decrease in lure weight during the first 3 day interval at 20 and 25 degrees C.
