Abstract： [Objectives] To verify the effects of the host plant volatiles on the behavior of adult Batocera lineolata Chevrolat. [Methods] The electroantennogram and behavioral responses of the B. lineolata adults (unmated females, unmated males and mated females) to 10 kinds of plant volatiles were tested with EAG and a Y-tube olfactometer. [Results] The ten test chemicals induced clear EAG responses. B. lineolata adults had the strongest EAG responses to the tested plant volatiles when the concentration was 100 μg/μL. The EAG responses values of unmated female and male and mated female B. lineolata adults to (Z)-3-Hexen-1-ol were the highest, being 2.35, 2.31 and 2.22, respectively. As for behavioral responses, unmated female and male B. lineolata adults were strongly attracted to (Z)-3-Hexen-1-ol, whereas Linalool had an obvious repellent effect on unmated female and male B. lineolata adults. None of the compounds tested were attractive to mated female B. lineolata adults. [Conclusion] The results provide some theoretical basis for the development of effective attractants for B. lineolata.
