Abstract
The paper reports attractant (kairomonal) property of some compounds isolated from the bark of Sal (Shorea robusta) against its dreaded pest Sal borer, Hoplocerambyx spinicornis, in laboratory. Extract of the bark and its various isolates were prepared by the standard procedure and subjected to bioassay. Phase-wise bioassays of the bark extract and its further isolated compounds were carried out against the beetles in choice conditions in laboratory. Behaviour exhibited by the beetles, viz., orientations, walking movement, antennal activity, visits to the test compound treated surface, biting and feeding attempts to the particular compound and number of beetles attracted has been recorded. They showed positive behaviour with regard to the parameters discussed above against the bark extract as well as other isolated compounds. The chemical analysis of the compounds exhibiting the kairomonal property has also been performed.
