Abstract
The controlling effect of parasitoids on vegetable leaf miner, Liriomyza sativae Blanchard, was evaluated by using act
ing factor life tables and exclusion inex of population control(EPIC). The results showed that Chrysocharis pentheus,
Neuchrysocharis formosa, Chrysonotomyia okazakii, Hemniptarsenus varicornis, Chrysocharis sp., Opius dimidiatus and Opius dissitus played an important role in controlling the population of vegetable leaf miner. The EIPCs of parasitoids were 1.23, 2.73, 5.98, 5.92 and 5.71, respectively for the five generations of L. sativae on kidney bean planted in spring, from the 1st to the 5th generation and, for the 2nd generation in particular, they were 2.73, 2.87, 2.24and 1.89, respectively on kidney bean, cowpea, luffa and cucumber, indicating that if the parasitoids were excluded, the population of the next generation of L. sativae would increase by times accordingly. The EIPC of parasitoids for the 3rd instar larvae was usually the largest among different instar larvae and pupae, and the EIPCs for the 3rd to 5th generation of L. sativae on spring kidney bean were higher than those for the 1st and the 2nd. The EIPCs of parasitoids for L. sativae on kidney bean and cowpes were larger than those on luffa and cucumber.
