- Recently, ~ of soybean is decrease because of the pest (Spodoptera sp.). Until now, the control of Spodoptera sp. depend on using of chemical element. N~ effect from using of synthetic chemical element is the appearance of secmdarypest, the death of useful insect and there is high pesticide residue in biotic also abiotic component in agroecosystem. The residue ofpesticide will disturb ofhuman health and environment balance. Because of that, so be done developing of control method with use biological agents which have pa1hogenicity to host. One of biological agents is entomopathogeuic nematodes. The aim of the research are using in vitro technology of entomopathogenic nematodes mass production as a biological control agents to pest (Spodtptera sp.). The research do in laboratory ofHPT UPN "Veteran" East Java, also a location of field. The result of the research is get 300.000-350.000 IJIspon size ยท1,5 cm3. There is increase preference of mortaJity persentage of the pest at the high sooner of dosage 1reat.ttlent. Maximal mOOality at 4 days after application. Lethal Dosage Value (LOso) is 1926,862 Ulplant. Conclussion, the entomopalhogenic nematodes (Steinernema spp. Tulungagung isolate) is effective to control Lepidoptera larvae until 4 days after application and the optimal dosage for control of Spodoptera sp. is IDso 1926,862 Ulplant (Infective Juvenilelplant).
