摘要
根据闽北小流域双季稻田害虫及天敌种群动态调查结果，分析和比较了稻田蜘蛛等天敌对稻飞虱的控制作用，及使用化学农药对天敌种群数量的影响，为拓宽防治指标、减少用药量，提供科学依据。
In double cropping rice fields of small watersheds in north Fujian, the effect of natural enemies,such as field spiders etc, on controlling planthopper has been analysed and compared based on the survey results of population dynamics of pests and their natural enemies, and the effect of chemical control on the natural enemy quantity It provided a scientific basis for enlarging the controlling index,decreasing chemical dosage in field practice
