Efficiency of parasitoids and predators of Halyomorpha halys and other Pentatomidae in Bavaria.
Damage due to Pentatomidae has increased in the last years in European fruit production. Next to indigenous stink bugs the invasive species Halyomorpha halys (Stål) is the main reason for this, a species that caused damage in fruit production only a few years after it was first detected in Europe. Since hope lies on parasitoids for a sustainable control of these pests it was evaluated how these pests are controlled in South-East Germany by antagonists. Antagonists had little impact on egg masses of H. halys and other Pentatomidae, although the impact was higher in hotspots of H. halys. These findings are in line with findings in previous studies, showing that control of H. halys by indigenous antagonists in Europe is little. The two Asian parasitoids Trissolcus japonicus (Ashmead) and Trissolcus mitsukurii (Ashmead) were not found in these investigations.
