- Until now, the control of Heliothis armigera depend on using of chemical element. Negatif effect from using of synthetic chemical element is the appearance of secondary pest, the death of useful insect and there is high pesticide residue in biotic also abiotic component in agroecosystem. The residue of pesticide will disturb of human health and environment balance. Because of that, so be done developing of control method with use biological agents which have pathogenicity to host. One of biological agents is entomopathogenic nematodes. Entomopathogenic nematodes have wide host range are Lepidoptera, Coleoptera, Diptera and Hymenoptera order, it hasn't negatif effect to environment. The aim of the research are using mass production technology of entomopathogenic nematodes as a biological control agents to pest (Heliothis armigera), get the optimal dose of Steinernema spp. (Local Isolate) for pest control in the field, giving to farmer an alternative controle of Heliothis armigera which save to environment, increasing corn product, make good quality ofliving people. The research do in laboratory ofHPT UPN "Veteran" Jawa Timur and in the field. In Laboratory is done mass production ofNEP and in the field is done effication test ofNEP to Heliothis armigera. The result of the research is get 300.000- 400.000 IJ/spon size 2 cm3 • The nematodes have maximal effect at 7 days after application; the effective dose for pest control of Heliothis armigera in Jember is 12.500 IJ/plant (Infective Juvenile/plant). Key word: Heliothis armigera, entomopathogenic nematodes, mass production, effication, infective Juvenile.
