毒环法防治杨尺蠖试验研究

Experimental Study on Prevention and Control of Apocheima cinerarius with Insecticidal Ring on the Trunk

为了防治杨树上树害虫杨尺蠖的危害,对该虫进行了多种防治方法的对比研究。结果表明:树干涂毒环防治杨尺蠖效果优于粘虫胶、透明胶带、废机油等方法。将毒环涂于透明胶带下缘2cm处理优于上缘防治效果。毒环防治害虫不杀伤天敌和鸟类、污染小、对人畜毒害低、生态效益显著,且方法简便、易于操作、省时省工、易于推广。

For the purpose of controlling the harm of Apocheima cinerarius on poplar, several kinds of experimental method were studied to prevent and control thepest. The results showed that the prevention and control effect with insecticidal ring on the trunk was better than sticky insect glue,transparent tape,waste engine oil, etc. The effect with insecticidal ring coated on the transparent tape bottom edge 2 cm was better than that of coated on the upper edge. The prevention and control method with insecticidal ring on the trunk could＇t kill natural enemies and birds,had low pollution and low toxicity for human,its ecological benefit was remarkable. Moreover, the method was simple, easy to operate,timesaving and easy to generalization.
