Tentative Biological Control Resource in Genus Asobara (Braconidae: Alysiinae) Identified from Morphological and Molecular Methods
Drosophila suzukii (Matsumura), commonly called the Spotted Wing Drosophila (SWD), originally from South Asia, is a major pest in orchards. Recently, chemical control was applied to prevent the SWD in cultivated fields, but it was not much effective because D. suzukii tended to avoid place where insecticide was treated, to reproduce in wild field, and then to recolonize neighboring cultivated fields. In contrast to chemical control, biological control can reduce these problems by using natural enemies who attack the D. suzukii. Some species of genus Asobara (Hymenoptera; Braconidae; Alysiinae) are parasitoids of Drosophila, and, In South Korea, there are 3 species recorded parasitizing in D. suzukii. In this study, we used morphological characters and mitochondrial COI gene to identify Asobara species. As a result, one species was found as a possible parasitoid of D. suzukii.
