A laboratory experiment was conducted at ICAR-National Bureau of Agricultural Insect Resources, Bengaluru to study the behavioural response of Trichogramma achaea towards healthy, conspecifics (Tuta absoluta oviposited on Tuta absoluta infested plants) and heterospecifics (Tuta absoluta oviposited on Liriomyza trifolii infested plants) tomato plants by choice and no-choice parasitization assays and olfactometer studies. Headspace volatiles were collected from tomato plants oviposited by conspecifics, heterospecifics and healthy plants, analysed using gas chromatography-mass spectrometry (GC-MS) where 14, 17 and 8 volatile organic compounds were detected respectively. Electrophysiological compounds and antennal response of T. achaea were identified using gas chromatography-electro-antennographic detector (GC-EAD). EAD active compounds of T. achaea were 3-Hexanol, α-phellandrene, trans-β-ocimene, pentacosane and γ-terpinene.
