摘要： Three winged morphs (parthenogenetic winged female, PWF; gynopara; and male) of the cotton-melon aphid Aphis gossypii Glover (Hemiptera: Aphididae) facilitate the migration and host transfer of this pest. However, host plants preferred by these three winged morphs and their released volatiles remain largely unclear. Herein, the summer host plants (Gossypium hirsutum and Brassica pekinensis) preferred by PWFs and the winter host plant (Prunella vulgaris) preferred by gynoparae and males were screened from 17 tested host plants. In addition, active components that elicited the electrophysiological responses of the antennae of three winged morphs were identified. Y-tube olfactometer bioassays showed that active volatile compounds such as dibutyl phthalate, cis-3-hexen-1-ol and alpha-pinene were significant attractants for three winged morphs. The identified olfactory active volatile compounds (OAVCs) were formulated at different ratios into 18 attractant formulae, of which 4 formulae exhibited desirable luring-enhancing effect on PWFs, gynoparae, and males. Styrene, cis-3-hexen-1-ol, a-pinene, and others were dominant ingredients. These four effective formulae were expected to develop environmentally friendly pesticides to control pests by blocking the migration of winged cotton aphids. Taken together, our findings provide research models for the development of new plant-derived green aphid control technologies based on the interactions between cotton aphid and host plants.
