Abstract

The management system of soybean agroecosystem with an intensive use of synthetic insecticides will reduce the diversity of parasitoid Hymenoptera species. The study aimed to compare the diversity of the parasitoids in soybean agroecosystem with and without insecticide application. The collection of the parasitoid used insect net and yellow tray. The results showed that the diversity index of the parasitoids during vegetative and generative growth of the soybean with the insecticide application was lower than the one without the insecticide application, which both were classified as moderate. The evenness indices during vegetative and generative growth were high. The richness index in vegetative phase with insecticide application was classified as low (0<2.3955≤2.5), while in the generative phase was classified as moderate (0<3.6118≤4). The richness index on the vegetative (0<2.6229≤4) and generative (0<3.8287≤4) from the agroecosystem soybean without insecticide application were classified as moderate. The similarity without insecticide application was lower than the one with insecticide application. The application of insecticide affects the species richness index (in the generative phase) and the similarity, that the value is lower than the one without insecticide.
