通过大田药效试验，采用基于经济阈值的建议判别规则和天敌影响模型，分析目前主推的杀虫剂对稻纵卷叶螟和天敌的影响。结果表明，从各药剂对稻纵卷叶螟的防治效果来看，每667 m2用20%氯虫苯甲酰胺SC 10 ml对稻纵卷叶螟防效好，50%丙溴磷EC 100 ml次之，这2个药剂可单独使用；毒死蜱和阿维菌素单用效果不够理想，需与其他药剂搭配使用。从各处理对稻田稻叶的保叶效果来看，氯虫苯甲酰胺处理最佳，其次为丙溴磷，阿维菌素与毒死蜱效果相近。在该试验条件和用量范围内，阿维菌素、丙溴磷、氯虫苯甲酰胺对稻田天敌黑肩绿盲蝽和蜘蛛有一定的负面影响，其中以阿维菌素影响最大。

The effects of main pesti-cides on Cnaphalocrocis medinalis Gue-nee and its natural enemy were analyzed though field efficacy trials by adopting suggest discriminant rule based on the economic threshold and predators influ-ence model. The results showed that the control effect of 20% chlorantraniliprole SC 10 ml per 667 m2 on Cnaphalocrocis medinalis Guenee was the best, and that of 50% profenofos EC was the second. Those two pesticides could be used alone. Single use effect of chlorpyrifos or avermectin is not ideal, they need to be used combination with other pesticides. The leaf protection effect of chlo-rantraniliprole was the best, and that of profenofos was the second. The leaf pro-tection effect of abamectin and chlor-pyrifos were similar. In this test condi-tion and the dosage range, avermectin, profenofos, chlorantraniliprole had cer-tain negative effects on natural enemy Cyrtorhinus livldipennis and spiders, and the effect of avermectin was the biggest.
