Developmental time of four parasitoids species on two leafminer species, Chromatomiya horticola (Goureau) and Liriomyza sativae (Blanchard) (Diptera: Agromyzidae)

Abstract

The time of development from egg to pupal stage of four native parasitoid species, Neochrysocharis formosa, Hemiptarsenus varicornis, Diglyphus isaea and Chrysocharis pentheus, on a native leafminer species, Chromatomyia horticola, and an exotic leafminer species, Liriomyza sativae, was examined in a laboratory. The developmental time of N. formosa and H. varicornis did not differ significantly between the two host leafminer species, but that of D. isaea differed slightly. The developmental time of C. pentheus on L. sativae was significantly longer than that of C. horticola. The present findings suggest that L. sativae and C. horticola may have similar suitability as a host for N. formosa, H. varicornis and D. isaea, but not for C. pentheus.
