Twenty-seven volatile compounds from the intact and tea geometrid larvae-damaged tea shoots, dissolved liquid paraffin at three dosages of 10-2 g/ml, 10-4g/ml and 10-6 g/ml, served as the tested odors, which were used in the detection of antennal-electrophysiological responses of Apanteles sp.

Electroantennogram responses of female cotton bollworm (Helicoverpa armigera ) to several plant volatiles were tested.

The result showed a regularity that the EAG responses follow the regularity: the virgin females>mated females>males no mated to 0.

【Objective】 This paper studied on the living habits and EAG Responses of Vespa nigrithorax in Xianyang area,which aimed to help the research of other species in other places of Shaanxi.

The antennae response of female adults of Spodoptera exigua to the crude extract and 4 fractions in different solvents (benzene, ethyl acetate, acetone and ethanol) from Artemisia argyi was investigated by using Syntech electroantenogram apparatus, and the repellent and deterrent characteristics of the crude extract and 4 fractions to S.
