Abstract
According to a field experiment at Research Farm of Tabriz University, Tabriz, Iran, during 2010-2011, four cropping system and two types of fertilizer were used to determine the effects of wheat-oilseed rape intercropping on the population density of wheat aphid, Sitobion aveana (Fabricius, 1775) and its natural enemies. The results showed that the decreasing of wheat aphid population density was in agreement with increasing of its natural enemies particularly ladybird, Coccinella septempunctata L., 1758 and common lacewing, Chrysopa carnea (Stephens, 1838). It was concluded that wheat-oilseed rape intercropping could control S. avenae especially under narrow wheat strips and high ratio of oilseed rape to wheat strips. Fertilizer treatments and their interaction with cropping systems had no significant effect on population density of wheat aphid and common lacewing, but the interaction of fertilizer with cropping system treatments was significant for population density of ladybird at the anthesis complete stage as 8:3 treatment (wheat: oilseed rape) under 50% chemical plus biological fertilizer had the highest mean number of ladybird. published by the International Journal of Biosciences | IJB
