摘要: The response of adult flower thrips Frankliniella intonsa (Trybom) (Thysanoptera: Thripidae) to conspecifics is investigated in Y-tube olfactometer bioassays. The results show that both males and females are attracted to the odours of adult males, which indicates a male-produced aggregation pheromone in this species. Gas chromatography-mass spectroscopy analyses of headspace volatiles collected on solid-phase microextraction fibres show that two major components and six minor components are present in volatiles from males but not in females. Further gas chromatography-mass spectroscopy analyses reveal that the two major components in head-space volatiles produced by F. intonsa males are the same compounds that are reported in volatiles of Frankliniella occidentalis males: (R)-lavandulyl acetate and neryl (S)-2-methylbutanoate. However, the quantity of these two compounds in the volatiles differs between the species.
