Results revealed that, ovipositing females are significantly attracted for oviposition to coconut leaf and larval frass volatiles than control. The chemicals present in leaf and frass viz., linalool (91.54%), acetophenone (87.58%) and limonene (80.65%) were more attractive among six electrophysiologically active volatiles. These three volatiles can be used to develop a semiochemical based pest management method.enPestsOpisina aranasollaCoconut black headed caterpillarHost finding behaviorPlant semiochemicalsOviposition preferenceFrass kairomonArticle
