Abstract
The chafer beetle, Holotrichia serrata F. (Coleoptera: Scarabaeidae) in its larval stage is a serious pest on sugarcane, vegetables, groundnut and coconut in many parts of India. The antennal response of adults to host volatiles and pheromone gland extracts was assessed by electroantennography. Among the preferred host of H. serrata, the volatiles from neem, Azadirachta indica A. Juss leaf extract elicited higher antennal response than gulmohar Delonix regia L. flowers and Ailanthus excelsa (Roxb) leaf extracts. The order of response was the same irrespective of the sex. In general the antennal response to pheromone gland and host extracts was higher in males than in females.
