Research on the application of the population strategy of brown planthopper Nilaparvata lugens Stal. (Homoptera: Delphacidae) carried out in an integrated with the aim to determine the effect of the application of integrated pest management ( IPM) to control brown planthoppers and the growth of rice plants. The experiment was conducted in the village of Kerumut, Pringgabaya District, East Lombok, West Nusa Tenggara and in pest Laboratory, Department of Plant Pests and Diseases, Faculty of Agriculture, Brawijaya University in January 2013 until July 2013. The research method used was experimental method. Observation variables include brown stem planthopper populations, natural enemies of brown planthopper, the intensity of the attacks, and the growth of rice plants. In this research, data were analyzed using t-test by comparing the observations between IPM treatment with conventional treatment. Observations and discussions indicate that 1) brown planthopper populations on IPM treatment was lower than the conventional treatment, 2) population of brown planthopper natural enemies higher and significantly different in the IPM treatment than conventional treatment, 3) the intensity of the attacks on IPM treatment lower and significantly different than conventional treatment, and 4) the growth of rice plants with IPM treatment lower than conventional treatments. The results concluded that the population of brown planthopper lower on IPM treatment than conventional treatment, population of brown planthopper natural enemies higher in IPM treatment than conventional treatment, the low population of brown planthopper on IPM treatment effect on the damage to rice crops, the IPM treatment attack intensity is lower than conventional treatment. Growth and production on the IPM treatment was lower than conventional treatment.
