| Abstract: | Summary Both geranyl hexanoate and geranyl octanoate were identified by GC/MS as the major volatiles in a hitherto uncharacterized abdominal gland in females inAgriotes obscurus. Only geranyl octanoate was found inA. lineatus. In EAG tests performed onA. obscurus males, geranyl butanoate and geranyl hexanoate elicited the strongest antennal responses.Financial assistance was donated by The Bank of Sweden Tercentenary Foundation and the Axel and Margaret Ax: son Johnson Foundation.
