The responses of Batocera horsfieldi adults to plant volatiles were tested with Y-tube olfactometer. The results showed that the volatiles from the rose had a higher attractive ability to both of unmated and mated male and female adults of Batocera horsfieldi compared with ambient air, and had a higher attractive ability to the unmated and mated female adults compared with poplar(P<0.05), while the volatiles had insignificant effect on the unmated and mated males(P>0.05). There were insignificant differences in the responses of unmated and mated males and mated females to the volatiles between the rose and poplar,and in the responses of the unmated %Batocera horsfieldi% to the volatiles between the poplar and osier(P>0.05).
