摘要: Abstract We determined feeding preferences of invertebrate seed predators and the effect predation on weed emergence. Feeding choice studies were completed with three species common ground beetles: (Amara aenea DeGeer, Anisodactylus sanctaecrucis F., Harpalus pensylvanicus DeGeer) (Coleoptera: Carabidae) northern field cricket (Gryllus pennsylvanicus (Orthoptera: Gryllidae). sanctaecrucis, H. pensylvanicus, female male G. consumed more redroot pigweed seeds compared giant foxtail seeds; A. consumption did not differ between these two species. All invertebrates fewer velvetleaf however, when biomass was compared, similar velvetleaf, foxtail, pigweed, whereas greater seed. Seed burial depths 0.5 or...
