【摘要】 为筛选出防治美洲斑潜蝇的高效药剂,以60%灭蝇胺水分散粒剂、25%噻虫嗪水分散粒剂为对照,比较了不同用量灭蝇胺·噻虫嗪水分散粒剂对美洲斑潜蝇的防治效果。试验结果表明,60%灭蝇胺·噻虫嗪水分散粒剂3个处理(26.6、20.0、13.3 g/667 m~2)对美洲斑潜蝇均具有良好的防治效果,药后7 d防效最好,防治效果分别为88.50%、82.31%和71.37%,且持效期为10 d以内。60%灭蝇胺·噻虫嗪水分散粒剂是防治美洲斑潜蝇较为理想的药剂,建议与其他农药轮用。更多还原

【Abstract】 In order to screen out efficient insecticides to control Liriomyza sativae, the control efficacy of different dosages of 60% cyromazine-thiamethoxam water dispersible granule(WDG) to L. sativae were compared, taking 60% cyromazine WDG and 25% thiamethoxam WDG as the control treatments. The results showed that the three treatments(the dosages of60% cyromazine-thiamethoxam WDG was 26.6, 20.0 and 13.3 g/667 m~2, respectively) had good control efficiencies on L. sativae. The best control effect was on 7 days after applying insecticides, with the control efficeicies of 88.50%, 82.31%and 71.37%, respectively. And the lasting period was within 10 days. Therefore, 60% cyromazine-thiamethoxam WDG was an ideal insecticide for preventing and controlling L. sativa, and it should be rotated used with other insecticides.更多还原
