摘　　要：Plutella xylostella is the main pest of cruciferae plants in the worldwide fields.The volatiles released from host plants serve vital roles in host-finding and oviposition behavior.Electroantennograms were recorded from male and female Plutella xylostella to 9 different plant volatiles(cabbage Brassica oleracea L.var.capitata,baby bokchoi Brassica chinensis L.,broccoli Brassica oleracea L.var.botrytis L.,Chinese cabbage Brassica pekinensis Rupr.,Radish Raphanus sativus L.,towel gourd Luffa Cylindrica Roem.,eggplant Solanum melongena L.,tomato Solanum lycopersicum,pepper Capsicum annuum L.) in healthy/injured status.The statistic analysis show there is a significant difference of EAG relative values between cruciferae and non-cruciferae volatiles.The EAG relative values of injured plant volatiles to both male and female changed a lot during the tests.Multiple-ANOVA analysis represents cross factors(sex,host-plant,plant status) showed a great interactive impacts to the EAG-RV.Plutella xylostella is the main pest of cruciferae plants in the worldwide fields.

Electroantennograms were recorded from male and female Plutella xylostella to 9 different plant volatiles ( cabbage Brassica ol- eracea L. var. capitata, baby bokehoi Brassica chinensis L. , broccoli Brassica oleracea L. var. botrytis L. , Chinese cabbage Brassica pekinensis Rupr. , Radish Raphanus sativus L. , towel gourd Luffa Cylin- drica Roem. , eggplant Solanum melongena L. , tomato Solanum lycopersicum, pepper Capsicum annuum L. ) in healthy/injured status. The statistic analysis show there is a significant difference of EAG relative values between cruciferae and non - cruciferae volatiles. The EAG relative values of injured plant vola- tiles to both male and female changed a lot during the tests. Multiple -ANOVA analysis represents cross factors (sex, host-plant, plant status) showed a great interactive impacts to the EAG- RV.
