摘要: 报道了小黄家蚁对褐稻虱的捕食作用。养虫笼及大试管捕食试验结果表明,小黄家蚁对褐稻虱若虫尤其是低龄若虫具有良好的捕食效果,捕食率分别为93%和30%, 捕食的功能反应为HolingⅡ型反应,水稻品种抗性与捕食反应之间存在协同作用。

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.
