    Proposal abstract:

    Halyomorpha halys is an invasive stink bug that causes damage to multiple commodities including peaches. Currently, there are few integrated pest management tactics available for H. halys, and research on natural enemies in the United States is skewed towards parasitoids and predators of eggs. In Chinese peach production, ground cover manipulation is a successful integrated pest management strategy for controlling arthropod pests. We propose using data from pitfall traps and molecular gut content analysis to identify ground-dwelling predators of H. halys and determine how ground cover management practices used in the Southeastern United States enhance biological control of H. halys nymphs.

    Project objectives from proposal:

    1. To identify the predators of BMSB that are present in Georgia peach orchards.
    2. To understand how existing ground cover management practices in Southeastern peach production impact communities of predators and their predation of BMSB.
