Plants release green leaf volatiles as constitutive or induced defense and that parasitoids might use these chemicals as cues for searching their herbivorous host has become a subject of intense research in the recent years. In addition to its contribution to enhance knowledge regarding tritrophic interactions, identification of the chemical cues are likely to give leads in development of chemical traps for management of parasitoids. Antheraea assama, the producer of golden yellow muga silk is parasitized by a dipteran fly, Exorista sorbillans and the seed broods of the silk worm suffer a great loss due to the parasitization. This work was carried out to study the response of the endoparasitoid E. sorbillans (Diptera: Tachinidae) to fed sualo (Litsea polyantha) leaves and certain pure green leaf volatile compounds. The study was done by subjecting adult female flies to different odour sources using olfactometer. Parameters considered were latency, rest, walking, grooming and proboscis extension period. Sualo leaves fed for different period of time, C6 aldehydes, monoterpene hydrocarbons, oxygenated monoterpenes and certain sesquiterpenes enhanced fly activity significantly. Certain compounds showed increased activity of the flies with increase in concentration of the compounds. The potential candidate compounds for E. sorbillans management are highlighted.
