Abstract

Rice is the staple food crops in Indonesian people, which is in production is always having problems of rice pests. Fitofag insects is one of the obstacles often faced by rice farmers in an effort to increase rice production. This research was to determine the effect of bioinsecticide application on Fitofag Insects Population and Predatory Arthropods in rice. The method used in this study is a randomized block design method with six treatments and five replications. The treatments consisted of a control (water), Ma 100mL + EKKU 600mL, Ma 600mL + EKKU 100mL, Bt + AK, Bt commercial, and EKKU. Dominant fotifag insects found in rice fields was Cofana spectra and Valanga nigricornis on 29-44 days after planting (dap), Leptocorisa acuta on >57 dap. While in ratoon was Cofana spectra and Scotinophora lurida on 21-28 dap, Valanga nigricornis on 14-49 dap. Arthropod predators most commonly found in rice fields were of Families Libellulidae, Staphylinidae, Coccinelidae, Tetragnathidae, Carabidae and Oxyopidae. While on ratoon were of families Coccinelidae, Lycosidae, Tetragnathidae, Oxyopidae, Carabidae and Staphylinidae. Rice plant sprayed by using insecticide active ingredient Bacillus thuringiensis and Metarhizium anisolpiae in dose 2L.ha-1 could not suppress fitofag insects populations of rice plants. The treatment could to increase abundance and diversity of arthropod predators and indicated the relative abundance and diversity index. Production of rice plants that applied biopesticide active ingredient Bt and Ma had no significant effect to increase the component of the production of rice plants.
