Behavioral response of the borer beetle Hoplocerambyx spinicornis to volatile compounds of the tree Shorea robusta.
Essential oils isolated from leaves (LO), bast (BO), heartwood (HO), and ethereal extract of resin (EER) of Shorea robusta were bioassayed with electroantennograph (EAG) and wind tunnel to study the behavioral response of male and female beetles, Hoplocerambyx spinicornis Newm., the most injurious heartwood borer of the tree. LO, BO, HO, and EER were shown to exhibit the electrophysiological activity in the female beetle, while LO and BO in the male beetle. In wind-tunnel studies, only BO elicited the attractant activity to both the sexes. A possible correlation of the constituents of the BO identified by GC/MS with the bioactivity is also presented.
