摘要:在 7 月上旬 ,将 80% 敌敌畏稀释成 4 种浓度，对野外馒头柳上的柳蓝叶甲进行田间对比试验，结果表明：不同浓度配比其虫口减退率有显著差异，随着浓度增加，防治效果也逐渐提高；但从保护天敌和避免害虫产生抗药性等综合因素考虑,采用1:500倍的80%敌敌畏防治柳蓝叶甲较适宜。

By 80% dichlorvos emulsifiable concentrates on controlling plagiodera testZhao Zemin(Academy of Forestry of Jilin city, Jilin city, Jilin 132013)Summary: in July early, will 80% dichlorvos diluted into 4 species concentration, on field buns Willow shàng of plagiodera versicolora Hieroglyphica for field compared test, results showed that: different concentration ratio its insect mouth decrease rate has significantly differences, with concentration increased, control effect also gradually improve; but from protection predators and avoid pest produced resistance, integrated factors considered, used 1: 500 times times of 80% dichlorvos control plagiodera versicolora Hieroglyphica more suitable.Key words: Dichlorvos; Plagiodera; insect population decline rate

The use of 80% dichlorvos EC against Plagiodera versicolora test

Zhao Zemin (Jilin Academy of forestry Jilin Jilin 132013) Abstract:

in early July, 80% dichlorvos diluted to 4 concentration, in the field of Plagiodera versicolora were steamed Liu field contrast test, results showed that: different concentration ratio of the population decline rate there is a significant difference, with the increase of concentration, the control effect is gradually increased; but in the protection of natural enemies and avoid pest resistance and other factors, the 1:500 times 80% dichlorvos prevention of Plagiodera versicolora suitable.
