摘要： In China, the genus Adelphocoris (Hemiptera: Miridae) includes three dominant pest species (A. suturalis, A. lineolatus and A. fasciaticollis), which cause great damage to cotton, alfalfa and other crops. In this study, we examined the role of the major volatile organic compounds from plants in host location by these three insects. Gas chromatography-electroantennography and gas chromatography/mass spectrometry analyses identified seven electroantennogram (EAG)-active compounds from 11 host plants. Although the insects responded to all of these compounds in EAG trials, some compounds did not elicit behavioral responses in Y-tube olfactometer bioassays. Adelphocoris suturalis adults showed behavioral responses to four EAG-active compounds, n-butyl ether, butyl acrylate, butyl propionate and butyl butyrate. These four compounds, in addition to p-xylene, were also attractive to A. lineolatus adults. However, A. fasciaticollis adults were attracted only by butyl acrylate, butyl propionate and butyl butyrate. In field trials, A. suturalis and A. fasciaticollis were each attracted to five individual compounds (m-xylene, n-butyl ether, butyl acrylate, butyl butyrate and butyl propionate for A. suturalis and m-xylene, butyl acrylate, butyl butyrate, butyl propionate, and 1,8-cineole for A. fasciaticollis). By contrast, A. lineolatus aduts were attracted to six individual compounds, m-xylene, p-xylene, n-butyl ether, butyl acrylate, butyl butyrate, and butyl propionate. These compounds may be important in host plant location by the Adelphocoris species, and may be useful for developing attractants for adults of these species.
