摘要
Abstract
It was tested that predatory quantity of the ladybird,Harmonia axyridis(Pallas) Var.Spectabilis,to the two aphid,Macrosiphum avenae and Rhopalosiphum padi at different densities in the certain space in the laboratory.The results showed that the selective coefficient of the ladybird varied with these two aphid populations.When the two pest population numbers increased synchronously,the ladybird preferred M.avenae. But when only R.padi increased,H.axyridis would obviously like to predate it.On the contrary,when only M. avenae increased,the ladybird would like to predate it.The result of the predatory quantity of the ladybird was similar to the selective coefficient.关键词
