Helicoverpa armigera Nuclear Polyhedrosis Virus (HaNPV) is one of the biological agents that could be used for the development of organic farming in Indonesia. One of the organic agricultural food products which have high economic value is cabbage, HaNPV effectif to control the population of several species of insect pests, can be used instead of synthetic insecticides in agricultural development efforts of organic cabbage. HaNPV formulation can be used as a way to maintain the virulence properties of the virus and facilitate the storage and application. The preparation of subculture HaNPV formulations was in liquid, powders, cornstarch and talk carrier material. The design experimental was used randomized block design consists single factor (type HaNPV formulation consisting of powder formulations, liquid formulation, formulation in cornstarch, and talc formulation including water formulation without virus as a control), with eight replications. The results showed that all of the formulations of subculture HaNPV causing larvae mortality at range 97.4% -100%. The highest mortality of larvae occurred in cabbage plants are protected by HaNPV carrier liquid and talk preparations by 100% each. Keywords: Formulations Helicoverpa armigera Nuclear Polyhedrosis Virus (HaNPV), subculture, Spodoptera litura, Brassica oleracea Var. capitata Linn.
