UNTUK MENGENDALIKAN ULAT Helicoverpa armigeraBiological control for pest and Agriculture plant disease is more effective and benefit if compared with
using p(!Sticide and chemistry insecticide. Using pesticide and chemistry insecticide was found to give negative
effect for environment. HaNPV ;s natural enemies for Hclicoverpa armigera larvae that attack agriculture plant
like corn, soybean and legumes. Helicoverpa armigera larvae also attack industrial plants such as cotton and
tobacco. Variety of HaNPV has been produced / isolated as Asembagus. Bogor and Yogyakarta isolat. The
effectiveness of HaNPV to control HaNPV depends on various factors. for example HaNPV isolat, concentration oJ
virus, and radiation. This research examines about minimal concentration of HaNPV Yogyakarta isolates ana
effectiveness of HaNPV to control H. amligera. Concentration of HaNPV 2 x ](1 PIBs/ml wasfound to be effectiw.
to control H. armigera larvae. By this concentration. lethal percentage of larvae was 85 % (Biological contrOl
