In each plot insects were collected by using a sweep net, pitfall and yellow traps. Insect observations performed at once a week, overall was 3 weeks. The result showed that diversity of insect is significantly higher in the farm without insecticide than the insecticide application, namely 1535 and 1177 insects, respectively. The non insecticide farm resulted to 19 Families from 8 Ordo and the insecticide' farm have only 17 families and also 8 Ordo. Therefore, the diversity index (H') is higher in non- insecticide than the insecticide application.
