| Abstrak ABSTRACT This study aims to determine the abundance of insects pest of rice on the treatment of several refugia plants.The study was conducted in July to August 2019 in a rice field in Mpenau village, Sigi Biromaru District, Sigi Regency. The research was continued at the Plant Pest and Disease Laboratory, Faculty of Agriculture, Tadulako University. Research in the field there are 3 plots taking samples, namely control, kenikir and marigold. The sampling method uses the yellow pan trap, sweep net and physically. Insect pests are identified to species level. The results showed that the total number of insects caught was 206 individuals from 6 Orders, 31 Families and 44 Species. The highest absolute abundance value in the vegetative phase is 18 individuals of the lowest lepidoptera order, namely 1 individual order of trichoptera and hemiptera, the highest relative abundance value is 45.16%, the lowest diptera order is 2.27% trichoptera order, the highest absolute frequency value of the 6 lowest diptera orders is 1 hemiptera order, trichoptera, coleoptera and orthoptera, the highest relative frequency values of 60% are listed and the lowest 6.25% are orthopterous orders. In the generative phase the highest absolute abundance is 20 lowest hemiptera orders, 2 coleoptera and orthoptera, the highest relative abundance was 46.53%, the lowest hemiptera order was 4.65%, the orthoptera order, the highest absolute frequency value of 7 orders is listed and the lowest is 1 order hemiptera and orthoptera the highest relative frequency value is 58.31%, the lowest order is 6.25%, the orthoptera order.
