摘要
本文对淮北地区飞机施药防治美国白蛾的效果进行了研究。结果表明,飞机喷施灭幼脲Ⅲ能有效控制第1代幼虫数量,持效期超过一个月,防治效果好,飞防区内第2、3代幼虫虫株率维持在较低水平,有效控制了全年的疫情。飞机施药防治与传统地面防治技术相比有着较大的优势,值得大面积推广。
In this paper a study was made on aerial-spray control effects of Hyphantria cunea in Huaibei region. The results showed that the effects of aerial-spray control with Chlorbenzuron Ⅲ were good in effectively controlling the number of the 1st-generation larvae and the validity period is over 1 month. The rate of plants infested with the 2nd and 3rd generations of Hyphantria cunea in the aerial-spray control area remained low and the bear-round pest situation was under effective control. Compared with the traditional ground control techniques, aerial-spray control has big advantages and is worth of being promoted on a large scale.
