“…(Heteroptera: Anthocoridae), Anthocoris nemoralis Fabricius (Heteroptera: Anthocoridae), Dalotia coriaria Kraatz (Coleoptera: Staphylinidae) and Labidura riparia Pallas (Dermaptera: Labiduridae) confirmed that these predators can feed on D. suzukii larval, pupal or adult life stages [22,23,24,25]. However, predator efficacy for D. suzukii control has been highly variable in these studies, and few have investigated egg predation [26,27].…”

“…Larval C. carnea , which is highly voracious, can consume 50 prey per day [34] and was selected for its wide host range, hunting capacity and resistance to certain pesticides [35]. None of these species have been evaluated against D. suzukii [26,27]. For comparison purposes, Orius insidiosus Say (Heteroptera: Anthocoridae) was included because it successfully caused 12–50% larval D. suzukii mortality in the laboratory [25].…”

Drosophila suzukii is an invasive pest and economic threat to berry crops in Europe and the Americas. Current methods of control of this pest rely primarily on frequent applications of insecticides; therefore, there is a need for alternative control methods to reduce insecticide reliance. In this study, we evaluated the biological control potential of three parasitoid wasps: Diglyphus isaea, Muscidifurax raptorellus and Pachycrepoideus vindemmiae, and four predators: Chrysoperla carnea, Dicyphus hesperus, Orius insidiosus and Podisus maculiventris. Experiments were conducted for 15 days under controlled conditions in experimental arenas with D. suzukii females and raspberries, allowing for all life stages of D. suzukii to be available to natural enemies. Results showed the first evidence of M. raptorellus’s ability to parasitize D. suzukii, resulting in a 40% reduction. Orius insidiosus, P. vindemmiae and C. carnea were also efficient, reducing D. suzukii numbers by 49%, 43% and 32%, respectively. Predator preferences for each D. suzukii life stage were assessed. The clutch size, sex ratio and adult size variability of D. suzukii pupal parasitoids were also evaluated. This study expands the list of species that can effectively parasitize D. suzukii and provides new insights into the biological responses of M. raptorellus to D. suzukii pupae.
