Abstract:

The EAG responses of male Holcocerus insuleris Staudinger to standard compounds Z3-14:Ac,Z3E5-14:Ac,E3-14:Ac and Z9-14:Ac were strong,but only Z3-14:Ac showed an obvious attraction and specificity in trapping tests.On an average,2.66 male moths were caught by a trap baited with 500μg of Z3-14:Ac per day,which was 1.8 time as many as the moths caught by a trap baited with one virgin female.The attractant-baited trap can be used to detect both the presence and density of the moths in the field.The sex attractant Z3-14:Ac discovered will provide a new way for integrated prevention and control of Holcocerus insuleris Staudinger.

Key words: Holcocerus insuleris Staudinger, Sex attractant, Z3-14:Ac, Field tests
