农药微胶囊剂防治松材线虫传播媒介——松褐天牛成虫的研究初报

The First Report of the Study on the Use of Pesticide Microcapsules to Control Monochamus Alternatus

在松褐天牛成虫补充营养期间 ,采用灭幼脲 3号微胶囊与其它农药微胶囊的混合制剂防治松褐天牛成虫具有很好的防治效果。以灭幼脲 3号微胶囊加安高杀Ⅳ号微胶囊(杂环类 )防治效果最佳 ,无论是速效 ,还是 1 0天、2 0天 ,30天后的持续药效均达 1 0 0 %。灭幼脲 3号微胶囊加安高杀Ⅰ号微胶囊 (拟除虫菊酯类 ) ,灭幼脲 3号微胶囊加安高杀Ⅲ号微胶囊(拟除虫菊酯和有机磷复配 )防治的效果也较好 ,但 30天后的持效有所降低。灭幼脲 3号微胶囊加安高杀Ⅱ号微胶囊 (有机磷类 )的防治效果稍差。而单纯使用灭幼脲

Absrtact:During the adult Monochamus alternatus taking food for supplementary nutrition, the mixture of dimilin 3 micro-capsule and other kinds of pesticide micro-capsul was sprayed to control them. The results showed that the controlling effect is significant,with the mixture of micro-capsuls of dimilin 3 and of Angosha IV showing the best effect. The direct effect and the persistent effect of 10, 20,30 days after spraying reached 100%. The mixture of micro-capsuls of dimilin 3 and of Angaosha I ,and that of dimilin 3 and Anaosha Ⅲ aslo showed better effect, but their persistent effect of 30 days after spraying decrease by some extent, and that of dimilin 3 and Angaosha Ⅱ behave relatively poor. However pure dimilin 3 micro-capsule showed poorer effect than all its mixture.
