Response of the brown stink bug (Hemiptera: Pentatomidae) to the aggregation pheromone, methyl (2E,4Z)-decadienoate.

摘要

Field-based experiments were conducted to evaluate the response of the abundant brown stink bug, Euschistus servus (Say), to commercially available pheromone lures containing methyl (2E,4Z)-decadienoate deployed in association with yellow pyramid traps. Euschistus servus aggregated over a zone of at least 3.14 m2 based on significantly greater numbers located on mullein plants located 1 m from baited traps compared with plants at 5 and 10 m. At this distance, ~96% of all adults located on mullein plants were not subsequently captured by baited traps. However, the presence of mullein plants near baited traps did not significantly reduce baited trap captures. Even if mullein plants were not present, baited trap captures remained statistically identical. Based on all adults captured in baited traps and located on surrounding mullein plants, 50% of all individuals that entered plots were captured in traps.
