在松褐天牛成虫补充营养期间,采用18 % 灭幼脲3 号微胶囊80 % 与其它农药微胶囊20 % 的混合剂,在松林喷雾防治松褐天牛成虫是有效的。以灭幼脲3 号微胶囊加安高杀4 号微胶囊( 杂环类) 防治效果最佳,无论是当时药效,还是10 天、20 天、30 天后的持续药效均达100 % 。灭幼脲3 号微胶囊加安高杀1 号微胶囊( 拟除虫菊酯类) ,灭幼脲3 号微胶囊加安高杀3 号微胶囊( 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2 号微胶囊( 有机磷类) 的防治效果稍差,单纯使用灭幼脲3 号微胶囊防治松褐天牛成虫无论是药效、持效都比不上混合使用的效果。
It is effective to control the adults of Monochamus alternatus by spray in the pine forest with 18% of the mixture of 80% diflubenzuron microcapsules 80% and 20% of other pesticide microcapsules during the nutritional supplementation of Monochamus alternatus adult. In order to MBH microcapsules plus microcosmic antimicrobial microcrystalline No. 4 (Heterocyclic) best control effect, either at the time of efficacy, or 10 days, 20 days, 30 days after the sustained efficacy of up to 100%. The effect of the prevention and cure of microcapsule No. 3 microcapsules plus Anxushang No. 1 microcapsules (pyrethroids), microcapsule No. 3 Microcapsules plus Anxusan No. 3 microcapsules (pyrethrin and organophosphorus compound) Better, but less effective after 30 days. The results showed that the control effect of microcapsule microcapsules No. 3 and Anzhang 2 microcapsules (organophosphorus) was slightly worse. The use of microcapsule No. 3 microcapsules to prevent and control Monochamus alternatus adults was not only effective but also effective Not mixed effect.
