THE BIOLOGICALTEST OF FORMULATION OF SUBCULTURE <i>Helicoverpa armigera</i> Nuclear PolyhedrosisVirus(<i>Ha</i>NPV) against <i>Crocidolomia pavonana</i> Fab. LARVAE POPULATIONTHAT EXPOSED TO CABBAGE (<i>Brassica oleracea</i> var. capitata L.)
Abstract
The biologicaltest of formulation of subculture Helicoverpa armigera Nuclear Polyhedrosis Virus(HaNPV) against Crocidolomia pavonana Fab.larvae population that exposed to cabbage (Brassica oleracea var. capitata L.) has been done. The subculture HaNPV was formulated in liquid preparations, powders, cornstarch and talc carrier materials, sprayed to C. pavonana larvae population that exposed at cabbage as a pilot project. The method of research used an experimental method, with randomized block design consists of single factor HaNPV and five level formulation there were (p) (liquid dosage forms (p1), powder (p2), and mixed with a carrier such as cornstarch (p3) and talc powder (p4) as well as the provision of water control without virus (p0)) with 8 replications. The density of virus 4x107 polyhedral/ml. The results was statistically analyzed with ANOVA (p<0,05), showed that all formulation HaNPV subculture have equal ability to caused high mortality of C. pavonana larvae population.
