Parasitism of the Invasive Brown Marmorated Stink Bug, <i>Halyomorpha halys</i> (Hemiptera: Pentatomidae), by the Native Parasitoid, <i>Trichopoda pennipes</i> (Diptera: Tachinidae)

The invasive brown marmorated stink bug, <i>Halyomorpha halys</i> (Hemiptera: Pentatomidae), has been an important agricultural pest in the Mid-Atlantic United States since its introduction in 1996. Biological control by native species may play an important role in suppressing <i>H...

The overall parasitism rate (in terms of <i>T. pennipes</i> egg deposition) was 2.38 percent. Rates differed among counties and seasons, but not between years.
