Research was conducted by considering about the performance of natural enemy of rice pest in the rice field of alumni and non-alumni Farmers Field School of Integrated Pest Control (SLPHT ? Sekolah Lapangan Pengendalian Hama Terpadu) in South Borneo. It starts from January to September 2013. Some research locations are included such as Pasar Kamis Village in Banjar District, Guntung Payung Village in Banjarbaru District, and Sungai Rangas in Banjar District. The performance of natural enemy of rice pest is understood using four kinds of trap, such as insect net (sweep net), light trap, yellow trap and pitfall trap. The examined parasitoid includes Telenomus rowani and Rogas narangae, which both are the parasitoid against rice stalk borer egg. The predator observed includes Agriope bruennnichi, Conocephalus longipennis, Clubiona sp, Verania discolor, Ophionea indica, Oxyopes spp, Paederus spp and Tetragnatha maxillosa. The pest used as prey is brown rice pest (Nilaparvata lugens Stall.) in either nymph or adult stadia.Result of research indicates that the parasitoid which parasite the egg of rice stalk borer is compared between PHT and non-PHT fields. The ability of parasitoid is more extensive in PHT field. The ability of predator to consume the prey is also compared between PHT and non-PHT fields and the result is varied. Only Conocephalus longipennis, Clubiona sp, and Tetragnatha maxillosa have higher ability of predating in PHT field.
