PARASITOIDS OF INSECTS ASSOCIATED WITH SOYBEAN AND VEGETABLE CROPS ININDONESIA

Field surveys were carried out in Indonesia on the islands of Java, Su matra, Sulawesi, and Bah from November 1994 to October 1997 to determi ne the parasitoid species associated with vegetable crops and soybean. Lepidopteran larvae were placed on artificial diet and brought to the laboratory for parasitoid emergence. Egg masses of sucking bugs also were collected or eggs from colony-reared bugs were placed in the fiel d and collected later. Leafminer-infested leaves were held in containe rs until emergence of parasitoids or adult flies. Eighty-five species of parastoids from 62 genera emerged from the collections. Most (92%) of the species were from four superfamilies: Ichneumonoidea (37 specie s or 44%), Chalcidoidea (31 species or 37%), Proctotrupoidea (9 specie s or 11%), and Bethoidea (I species). There were seven species of para sitic Diptera. Many of the parasitoid species, such as Diadegma semicl ausum Hellen (Hymenoptera: Ichneumonidae) on Plutella xylostella (L.) (Lepidoptera: Yponomeutidae), were clearly controlling host larvae. Om iodes indicata (F.) (Lepidoptera: Pyralidae) and Spodoptera litura (F. ) (Lepidoptera: Noctuidae) yielded 15 and II species of parasitoids, r espectively. Several undescribed species of parasitoids were found fro m a range of hosts. Several of the parasitoids are illustrated.
