Volatile chemical components of Dendranthema morifolium cv.Gongju in fields were successfully collected and analyzed by dynamic headspace bagging collection method combined with GC-MS analysis technology.59 volatile chemical components were identi-fied,including 30 alkanes,5 esters,4 alcohols,3 aldehydes,4 olefins,1 aether and 3 ketones.Test results of indoor Y-shaped tube selection behavior indicated that,when α-Pinene≥600 ng/μL,it has a significant repellent effect on 3rd instar aphids(P<0.05).It provided a theoretical basis for integrated management of tribute chrysanthemum aphid in Dendranthema morifolium cv.Gongju based on phytochemicals.
