Biological control of sentinel egg masses of the exotic invasive stink bug Halyomorpha halys (Stål) in Mid-Atlantic USA ornamental landscapes

摘要: Abstract Biological invasions have far reaching effects on native plant and arthropod communities. This study evaluated the effect of natural enemies eggs exotic invasive brown marmorated stink bug Halyomorpha halys (Stal) in experimental plots comprising species pairs 16 ornamental trees shrub genera from either Eurasia or North America wooded areas adjacent to plots. Sentinel egg masses were placed leaves Acer, Cercis, Hydrangea, Prunus seven shrubs woods. Overall, rates parasitism predation low, accounting for only 3.8% 4.4% mortality, respectively. There no significant differences between plants different genera. In 2015, was significantly higher than sites, but sites. plots, one parasitoid attacked sentinel masses. Six Parasitoids genus Trissolcus more likely attack is evidence that attacking BMSB prevalent landscapes with those shrubs.
