Seasonal occurence and host spectrum of egg parasitoids associated with soybean stink bug. Control of the brown stink bug in the early s was difficult due to the n0n-existence of effective insecticides.

The population from Londrina at the Embrapa Soybean Research Station, northern Parana state was among the most susceptible, whereas the population from Pedrinhas Paulista southwestern Sao Paulo state was among the least susceptible. During autumn, individuals seek for shelters under leaves and cultural remains and undergo a diapause, a period where no feeding activity is observed and that may last up to seven months.
