Ground and Rove Beetles (Coleoptera: Carabidae and Staphylinidae) are Affected by Mulches and Weeds in Highbush Blueberries

摘要: ASTRACT Biological control of insects by predators may be indirectly influenced management practices that change the invertebrate community in agroecosystems. In this study we examined effects mulching and weeding have on predatory beetles (Carabidae Staphylinidae) their potential prey a highbush blueberry field. We compared beetle communities unweeded plots to those were weeded / or received single application compost pine needle mulch. Compost mulch significantly affected carabid while staphylinid responded mulches. Effects because tended intensify year after for both families. Estimates species richness diversity Carabidae Staphylinidae similar all plot types, but rarefaction curves suggested higher unmulched despite fewer individuals captured. Carnivorous Carabidae, dominated Pterostichus melanarius,...
