Faculty of Agriculture, Udayana University, Denpasar,Bali 2.The Research Institute for Spices and Medicinal Plants, Bogor,West Java,Indonesia Abstract The research objective was to determine the population abundance and the level of parasitation of parasitoid of Neochrysocharis formosa and Neochrysocharis okazakii against Liriomyza spp on some vegetable crops in Bali (Indonesia) from March 2014 to December 2014. The method used is a survey method; the sampling of Liriomyza spp infected plants was conducted by purposive sampling on the low, medium and high land in Bali.The results showed that the population abundance of N.formosa on planting vegetables in Bali with the highest population respectively in the low, medium and high lands at 642, 409 and 162 populations. N.okazakii in the low, medium and high lands is 243, 99 and 10 populations. N.formosa parasitation highest level was found in the low, medium and highlands respectively on tomatoes, chicories, tomatoes, while N.okazakii on tomato plants. Both parasitoids associated with L.sativae in the lowlands, medium and highlands, with L.huidobrensis only in the medium and highlands.
