The occurrence of parasitoids of Liriomyza trifolii (Burgess) in Taiwan
Chinese Journal of Entomology 12 (4), 247-257
Abstract: Seven species of hymenopterous wasps that are parasites on the American serpentine leafminer, Liriomyza trifolii (Burgess) were found during a survey conducted in central Taiwan from May 1988 to March 1990. They were Hemiptarsenus varicornis (Girault), Chrysocharis pentheus (Walker), Chrysonotomyia okazakii (Kamijo), Chrysonotomyia sp., 1, Halticoptera sp.2, and Opius sp.. Over 51% of the parasitoid wasps collected in the field were H. varicornis; hence this species was considered the most important natural enemy of L. trifolii in Taiwan. C. okazakii (Kamijo) and undetermined Opius sp. were for the first time recored as parasitoids of L. trifolii. We present a taxonomic key of these seven species. The host range, world distribution and the parasitic potential of each species are given and discussed.
