Characterizing Trichogramma (Hymenoptera: Trichogrammatidae) species for biocontrol of light brown apple moth (Lepidoptera: Tortricidae) in grapevines in Australia
Annals of the Entomological Society of America 90 (2), 128-137
Abstract: Our objective was to characterize endemic strains of Trichogramma for further assessment of their potential commercial use for biocontrol of light brown apple moth, Epiphyas postvittana (Walker), in vineyards. There has been very little work on the endemic Trichogramma fauna in Australia and its potential for commercial use. We collected Trichogramma spp. from E. postvittana eggs at vineyards throughout southeastern Australia and separated species using morphological, electrophoretic, biological, and geographical criteria. The development times of the 4 most commonly collected species were useful in separating an undescribed Trichogramma (Trichogrammanza) species which had not been clearly identified morphologically. This new species may be adapted to lower temperatures than the other species collected, but its commercial potential is currently limited by its rejection of Sitotroga cerealella (Olivier) as a rearing host. An all-female thelytokous strain of this species was isolated. Another endemic species, Trichogramma (Trichogrammanza) carverae (Oatman and Pinto) has been mass reared successfully on S. cerealella and is being evaluated in field trials for control of E. postvittana.
