    Abstract

    Parasitoids that associate with L. sativae found on lowland vegetables ecosystem in Indonesia have very sparse information. The objective of this research was to identify species of L. sativae parasitoids and to analyze their species diversity on various cultivated and non-cultivated plants (weeds). Survey of L. sativae parasitoids was conducted on lowland vegetable centers on South Sumatra, such as Gelumbang, Tanjung Raja, Inderalaya, and Talang Kelapa. The adult parasitoids and the apparent parasitism of L. sativae were obtained by rearing from infested leaves in the laboratory. Fourteen species of the hymenopterous parasitoids found in the vegetable crops and weeds were Opius dissitus, Hemiptarsenus varicornis, Asecodes sp., Diglyphus albiscapus, Diglyphus sp., Neochrysocharis okazakii, Neochrysocharis sp., Quadrasticus liriomyzae, Quadrasticus sp. Gronotoma micromorpha, Diphoropria kushell, Diphoropria sp., Chrysonotomyia sp., and a mymarid wasp, unidentified species (Mymaridae). The highest apparent parasitism of L. sativae was found on cucumber (18.75%), whereas it could achieve up to 100% on weeds. However, L. sativae parasitoid abundance was significantly higher for vegetables than that of weeds. N. okazakii was parasitoid species that always found at various host plants on South Sumatra. Species diversity index of L. sativae parasitoid on cucumber, squash, cowpea, and tomato was higher than that of weeds.
