Abstract: The predation of Monomorium pharaonis on the brown planthopper (Nilaparvata lugens) was reported for the first time in this paper.The results of predation experiment conducted both in rearing cage and in big test tube showed that M.pharaonis had a strong predation effect on nymphs of brown planthopper, especially on young nymphs, with an average predation rate of 93% and 30%, respectively.The functional reaction of predation belonged to the Holling IIreaction, and the predation was significantly promoted by the resistance of the host rice varieties.
