    Abstract

    Slug caterpillars Setora nitens have been appearing to be more serious pest of oil palm as it might cause frond damages up to 90%. Many effort has been made to control the caterpillars using insecticides but the insects still existing and causing significant damages to the palm. Microbial insecticides especially the one developed from indigenous entomopathogenic virus, is a promising method of controlling the insect since its toxicity to non target animals and humans is extremely low. A conventional way of controlling S. nitens using crude sap of infected larvae had been applied in several oil palm plantation in Sumatera island as biological control agent of slug caterpillar was conducted to comprehend the pathogenicity and virulence of entomopathogenic virus and to reveal the morphological identify of its particle. The results showed that the use of virus infecting caterpillars to control the insect was quite successful in term of increasing the number of infected caterpillar and reducing the rate of population developments. Some caterpillar could spine cocoons but failed to release adult moth. Purification of the virus particles from infected caterpillars resulted in the appearance of white band in the sucrose gradient contained spherical shape of virus particles justifying that the agent infecting S. nitens caterpillar is a virus which still need further analysis for its complete identification
