Abstract: "Data and observations on wild tachinid flies that were attracted to traps baited with known or suspected pheromones for the following stink bugs (Hemiptera: Heteroptera: Pentatomidae) are reported: Podisus maculiventris (SAY), Euschistus tristigmus (SAY), Thyanta custator accerra MCATEE, Acrosternum hilare (SAY), and Halyomorpha halys (STÅL). Halyomorpha halys, called the brown marmorated stink bug, is a newly invasive species in the eastern U. S., while the other stink bugs listed are native North American species. The following known tachinid parasitoids of stink bugs were captured: Euclytia flava (TOWNSEND) (Phasiinae), Gymnosoma par (WALKER) (Phasiinae), Euthera tentatrix LOEW (Dexiinae), Hemyda aurata ROBINEAU-DESVOIDY (Phasiinae), Cylindromyia fumipennis (BIGOT) (Phasiinae), and Trichopoda pennipes (F.) (Phasiinae). Tachinids in the subfamily Phasiinae commonly exploit pheromones to guide their search for potential hosts. The findings of the current study bolster this conclusion, and provide clues to pheromones and host/parasitoid relationships yet to be discovered".
