摘　　要：农田鼠害生物防治的可行性是人们非常关心的问题,也是鼠害综合防治的一个重要环节。本文着重从食性入手,观察研究了珠江三角洲黄毛鼠天敌滑鼠蛇的食性,以及其摄食量与温度、湿度的关系;并且还对黄毛鼠的另一类天敌(号鸟)类的食量情况作了初步观察。提出了对天敌在黄毛鼠生物防治的作用应采取一分为二的态度,一方面不宜过高估计其灭鼠作用,另一方面也应禁止捕捉鼠类天敌,保护其生活环境,维持生态平衡。Snakes and eagles are natural enemies of mice. It were reported in this paper that the food habit of Ptyas mucosus, one kind of snakes which is called a major natural enemy of Rattus rattoides exiguus in the Zhujtang River Delta, and the relationship between its food quantity and the temperature, humidity of the surroundings. So was the primary observation about the food eaten by Glaucidium casuloides and Tytonidae capensis, two kinds of fierce birds, also the natural enemies of mice. The result of the observation indicated that the ability of the natural enemtes＇killing mice should not be evaruated highly, on the other hand, it must be forbidden to catch the natural enemies so as to keep ecological. balance.
