Potential host ranges of three Asian larval parasitoids of Drosophila suzukii

摘要: Asobara japonica (Hymenoptera: Braconidae), Ganaspis brasiliensis and Leptopilina Figitidae) are Asian larval parasitoids of spotted wing drosophila, Drosophila suzukii (Diptera: Drosophilidae). This study evaluated these parasitoids’ capacity to attack develop from 24 non-target drosophilid species. Results showed that all three were able parasitize host larvae multiple species in artificial diet; A. developed 19 tested species, regardless the phylogenetic position L. 11 species; G. only four exposed Success rate parasitism (i.e., probability an adult wasp successfully emerged a parasitized host) by two figitid was low hosts other than melanogaster group (D. melanogaster, D. simulans, suzukii). The failure figitids most appears correspond with more frequent encapsulation hosts. results indicate is specific suzukii, attacks mainly generalist, at least physiologically. Overall, developmental time increased host’s time. body size female (as model species) positively related size, mature egg load wasps size. We discuss use for classical biological control suzukii.
