应用昆虫性信息素<反—3、顺—13,十八碳二烯醇>防治白杨透翅蛾,做为一种新手段,于一九八二年在省内鉴定通过了。但是,这项新成果在生产实践中应用效果如何,还有必要继续加以研究。为此,一九八三年,我们又分别于梨树、怀德及双辽三县,在二万九千四百三十三亩林地内,进行了大面积应用试验,现将应用效果报告如下。一、材料与方法 (一) 材料来源 <反—3、顺—13,十八碳二烯醇>由江苏省昆虫激素研究所提供,剂量15克,纯度89
The application of insect sex pheromone (trans-3, cis-13, octadecadienol) as a new means of prevention and control of poplar moth, was appraised and passed in the province in 1982.
