本研究采用持效期达 3 0天以上的复合橡胶载体的新型诱芯诱捕器对马尾松毛虫进行林间监测 ,发现诱蛾数量与田间调查的幼虫数量有很大的关联性 ,各乡镇每诱捕点平均诱蛾数与 1代、2代幼虫虫株率、平均虫口的变化趋势基本相同
In this study, a new type of entrapment trap with a composite rubber carrier with a holding time of more than 30 days was used to monitor the mass of Dendrolimus punctatus. It was found that there was a significant correlation between the number of lures and the number of larvae in the field. The average number of trapping moths was similar to that of the first generation and second generation larvae, and the trend of the average population was the same
