【Abstract】 The olfactory responses of the Coccinella septempunctata Lewis, Prophlaea japonica Lewis and Harmonia axyridis (Pallas) to Macrosiphum avenae (Fabricius). Aphis sophoricola Zhong, Chaito phoruspopuleti (Pznzer), A. citricola van der Goot, A. gossypii Glover and their host plants were examined using a four arm olfactometer. The results showed that the C. septempunctata Lewis was strongly attracted towards the combination of the aphid infested leaves of the poplar tree and C. populeti (Pznzer) odors, P. japonica Lewis was strongly attracted towards the combination of the aphid: A. citricola van der Goot and the aphid infested leaves of the apple tree and H. aryridis (Pallas) was strongly attracted towards the combination of A. gossypii Glover and the aphid infested leaves of the rose mallow.更多还原
