ABSTRACT
Oil palm (Elaeis guineensis. Jacq) is a leading plantation commodity in Indonesia. The main problem in palm oil cultivation is the attack of the nettle caterpillar (Setora nitens. Walker). S. nitens attack can of producing plants and can reduce production by about 69%. The use of entomopathogenic bacteria Streptomyces sp. can be alternative to controlling nettle caterpillar S. nitens in a safe way. This research aims to find out the effectiveness to controlling S. nitens. The research was conducted at the Laboratory of Plant Pest and Experimental Garden at the Faculty of Agriculture, University of Riau, in Desember 2021 untill Februari 2022. This research used a completely randomized design (CRD) with four treatments of entomopathogenic bacteria Streptomyces sp. consist of 4 treatments 5 replications. The treatments given were entomopathogenic bacteria Streptomyces sp. with different concentrations, including 0%, 25%, 50% and 75%. The results showed the application of entomopathogenic bacteria Streptomyces sp. had a significant effect on the death S. nitens. The application of bacteria at a concentration of 50% was an effective concentration on the death S. nitens larvae which was able to cause a total mortality of 85% with a first time death of 7.20 hours after application and a lethal time of 50 at 16.60 hours after application. The right concentration to on the death 50% of S. nitens larvae was 18.3% and the right concentration to on the death 95% of S. nitens larvae was 75% concentration.
