10%氯虫苯甲酰胺微囊悬浮剂防治美国白蛾试验

本文研究了在鱼虾养殖等水域采取无人机和喷雾机喷施不同浓度的10%氯虫苯甲酰胺微囊悬浮剂防治美国白蛾幼虫的效果。结果表明：无人机每亩喷施10ml、15ml、20ml防治美国白蛾2-3龄幼虫,施药15d后防治效果后分别达到57.43%、73.15%、88.28%；喷雾机喷施1500、2000和2500倍液防治美国白蛾1-3龄幼虫,施药15d后分别达到94.82%/88.51%、87.63%。在防治生产上,防治时期以美国白蛾幼虫1-2龄为佳,选择喷雾机喷施10%氯虫苯甲酰胺微囊悬浮剂1500倍液防治效果显著；在树木高大、交通不便的林分,可采用无人机每亩喷施20ml药剂,防治效果良好。该药剂对鱼虾安全,可在鱼虾养殖等水域大面积推广,能有效降低美国白蛾虫口基数。

Control experiment against Hyphantria cunea ( Drury) with Chlorantraniliprole 10% CS

The control effect of different concentrations of Chlorantraniliprole 10% CS with drones and spray machine was studied in the waters of fish and shrimp aquaculture.The results showed that 10ml, 15ml and 20ml per mu were applied to control the 2nd - 3rd instar larvae of Hyphantria cunea ( Drury), and the control effects after 15 days of application reached 57.43%, 73.15% and 88.28% respectively. Chlorantraniliprole 10% CS were dilute by 1500, 2000 and 2500 times to control 1nd - 3rd instar larvae by spray machine. The control effects after 15 days of application reached 94.82%, 88.51% and 87.63% respectively. In terms of control production, 1nd - 2rd instars of the larvae of Hyphantria cunea were the best control period, and the spray machine was used to spray Chlorantraniliprole 10% CS with 1500 times solution. In the area with tall trees and inconvenient traffic, the drones can be used to spray 20ml agents per mu, and the control effect is good. The drug is safe for fish and shrimp, and can be widely used in the waters of fish and shrimp aquaculture, and can effectively reduce the insect populationSbase of Hyphantria cunea.
