Abstract:
Laboratory experiments were performed to determine the potential of dominant spider species in winter wheat in Germany, Erigone atra (Blackwall), Lepthyphantes tenuis (Blackwall) and Pardosa agrestis (Westring) adults and youngs, in suppressing the population of Rhopalosiphum padi (L.) on wheat plants and their functional response to different aphid densities. The presence of spiders significantly caused between 34 and 58% reduction in aphid population development on wheat plants compared to the aphid population in the absence of spiders. The functional response curves for these spiders as predators of R. padi seem to descrive a typical type II functional response with the prey consumed increasing to a plateau as aphid densities increased. Prey killed without eating was linear on prey density. © 1993 Lavoisier Abonnements.
