摘要
杨干象(Cryptorrhynchus lapathi L.)是一种世界性的危险性杨树检疫害虫。分布在我国东北、华北、西北等地区,是一种毁灭性的蛀干害虫,对杨树威胁极大。当前国内外对该虫的控制仍然普遍使用常规农药,不仅对环境易造成污染,而且残效短、成本高。本项研究是将氧乐果加工成微胶囊缓释剂,应用更有效、经济、安全、合理。这种新技术的应用为杨干象等害虫的综合防治开辟了一条新途径。
Osier weevil (Cryptorrhynchus lapathi L.) is a world wild dangerous quarantine pest of poplar. It distributes in northeast and northwest in our country and it is a ruinous borer. It jeopardizes the high-yield poplar forests, poplar shelter belt and the afforestation of city and country side. The pest is mainly controlled by using conventional pesticides in the world at present. Those kinds of expensive pesticides not only pollute environment, but also have a very shot residual activity. This experiment aims at making omethoate into encapsulated control release formulation so that it is possible for us to use this kind of pesticide reasonably, effectively, safety and economically. The success of this formulation lays a new way for the entegrated control of osier weevil.
