The oviposition behaviour of female Trichogramma australicum on host eggs and glass beads was tested. No washing by organic solvent or water could effectively remove recognition cues from Helicoverpa armigera eggs. Possible recognition kairomonal materials (accessory gland secretion and lateral oviduct liquid contents of H. armigera) did not have a pronounced effect on stimulating ovipositor probing and drilling by T. australicum.
