Natural enemy impact on eggs of the invasive brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), in organic agroecosystems: A regional assessment

摘要: Understanding native natural enemy impacts on the invasive brown marmorated stink bug, Halyomorpha halys (Stal), offers insight into population dynamics of this pest and potential for biological control. This two-year study a broad-scale assessment mortality factors affecting sentinel naturally laid H. eggs in agroecosystems pest’s invaded range eastern North America. Predation parasitism rates varied among states crops, but overall were low. Average maximum levels control estimated to be about 19% 20% 2013 2014, respectively. Of destroyed by enemies, chewing predation was most prevalent. Parasitism parasitoids very low, with adult emerging from 1 individual parasitoid emerge egg mass. complex is an important regulation factor its Asian range, found that US do not provide service introduced region. The greatest may via classical Trissolcus japonicus (Ashmead), which has recently been detected both western US.
