This paper reports on the EAG and behavioral responses of unmated females, unmated males, and mated females of Batocera horsfieldi (Hope) (Coleoptera: Cerambycidae) to ten plant volatiles. Seven volatiles tested from the host species Viburnum awabuki K., Betula luminifera H. Winkl, Juglans regia L., and Populus tomentosa Carr. were β-myrcene, (Z)-3-hexen-1-ol, nonanal, dichloromethyl ether, salicyaldehyde, 3-methylbutyric acid, and trichloroethylene. Three volatiles tested from non-host conifers were (1S)-(−)-β-pinene, (1R)-( )-α-pinene, and (1S)-(−)-α-pinene. The EAG responses of unmated B. horsfieldi females to these ten volatiles were tested at five concentrations (0.0001, 0.001, 0.01, 0.1, and 0.2 µL/µL). For eight of the volatiles, the EAG responses did not change significantly after their concentration was increased to 0.1 µL/µL. However, the maximum EAG response to 3-methylbutyric acid was at 0.0001 µL/µL and it decreased at higher concentrations. The EAG response to salicyaldehyde increased throughout the range of concentrations. The EAG response of mated females to salicyaldehyde at 0.1 µL/µL was significantly stronger than for unmated females or unmated males. EAG data showed that (1S)-(−)-β-pinene at 0.2 µL/µL had a strong repellent affect on unmated female and unmated male B. horsfieldi adults (P < 0.01). At 0.2 µL/µL, (Z)-3-hexen-1-ol had an attractive effect on unmated females (P < 0.05) and salicyaldehyde had an attractive effect on mated female B. horsfieldi adults (P < 0.05) in a Y-tube olfactometer. There was no significant difference in the repellent or attractive effects of dichloromethyl ether, 3-methylbutyric acid, or (1R)-( )-α-pinene at five concentrations to unmated female or male B. horsfieldi adults.
