舞毒蛾(Porthetria dispar L.)是世界有名的森林和果树的大害虫,分布极广,食性很杂。为了避免长期使用化学农药带来的缺点,人们早就探索用昆虫性信息素作为防治手段。经过三十多年的努力,Jacobsobn于1960年从十万只舞毒蛾雌蛾腹部末端的两节提取分离得到12毫克活性物质,命名为Gypol,化学结构为顺—7—十六碳烯—1—羟基—10—醋酸酯,又有其类似物命名为Gyplure,结构式为顺—9—十八碳烯—1—羟基—12—醋酸酯。并于1961年在一个400平方哩的岛上用飞机喷洒Gyplure的液剂和颗粒剂。这些液剂在室内试验时虽有一定的引诱作用,但野外试验未获成
Gypsy moth (Porthetria dispar L.) is a large pest of the world’s famous forests and fruit trees, a very wide distribution, diet is very mixed. In order to avoid long-term use of chemical pesticides brought shortcomings, people have long been exploring the use of insect sex pheromone as a means of prevention and control. After more than 30 years of hard work, Jacobsobn isolated and isolated 12 milligrams of active substance from two abdomen ends of one hundred thousand Gypsy moths in 1960 and named Gypol. The chemical structure is cis-7-hexadecene-1 -hydroxy-10-acetate, and its analogue named Gyplure, structural cis-9-octadecene-1-hydroxy-12-acetate. And in 1961 on a 400 square mile island by plane spraying Gyplure liquid and granule. Although these liquids have a certain inducing effect in laboratory tests, the field tests have not been completed
