【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 Holling Ⅱ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 ef
fect 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.
Key words Monomorium pharaonis , Nilaparvata lugens , Predation , Insect resistance ,
Natural enemy.
