Host-plant mediated influences on population development of Sitobion avenae (Stenorrhyncha: Aphididae)

Original language description

We investigated the effects of genetic differences and host plant density on population development of Sitobion avenae in winter wheat stands. Aphid numbers on ears were recorded on 11 cultivars and on plots were crop density was varied by thinning. Crop density significantly affected whole plant, tiller and ear mass, number of tillers, and leaf area and chlorophyll content. The duration and rate of aphid population growth, and the maximum numbers of aphids were ascertained by weekly counts. Maximum abundances increased with the length of time available for the growth of aphid populations while the rate of population growth was less important. Variation of maximum numbers on different cultivars was not significant. By contrast, there was a significant variation in aphid performance associated with host plant density. Aphid populations on solitary plants persisted longer and became more abundant than in dense stands.
