Toxicology of Nuclear Polyhedrosis Virus, Botanical and Synthetic Pesticides on Mortality Rate of Crocidolomia binotalis (Zeller)

Crocidolomia binotalis (Cb) (Zeller) is one of the main pests cabbage which difficult for farmers to control in Ijen Crater Indonesia. The demand Indonesia increasing every year, so intensification efforts are continuously being made. Farmers intensively use synthetic pesticides as primary Cb. purpose this study examine several agents that can be used an alternative pesticides. Then, it provides recommendations adapt reducing biopesticide was based on Nuclear Polyhedrosis Virus strains Spodoptera litura (SlNPV) and Helicoverpa armigera (HaNPV), botanical pesticides, a comparison treatment. SlNPv HaNPV isolates were obtained from Indonesian Sweetener Fiber Crops Research Institute. pesticide formulas come combination Azadiracta indica, Aglaia odorata, Ageratum conyzoides dried week proposed form flour. extracted using 96% ethanol solvent, 0.5% tween 90 rotary evaporator at temperature 40oC. For pesticide, treatment active ingredient Permethrin 20 mgL-1. cb collected field re-filtered Petri dish by providing artificial feed soaked with material 5 minutes. highest mortality test results found formula value 100% 72 hours. Mortality SlNPV tended stable maximum 72.02%. testing laboratory recommendation Cb plants field. In case, effort reduce farmers' dependence
