小黄家蚁工蚁对褐稻虱的捕食作用

Predation of Monomorium pharaonis on Nilaparvata lugens.

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．

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 II reaction, and the predation was significantly promoted by the resistance of the host rice varieties.
