目的:观察三氟氯氰菊酯微胶囊悬浮剂在不同载体表面杀虫活性持续时间。方法:在4种载体表面,按不同剂量(mgai/m~2)喷涂一定药液,采用强迫接触法观察其持续效果。结果:1.在玻璃板面按20mgai/m~2给药,对家蝇持续效果为90天;淡色库蚊及德国小蠊为100天。2.在油漆板面剂量同上对家蝇、淡色库蚊及德国小蠊的持续效果均有90天。3.在水泥板面按25mgai/m~2,对家蝇和淡色库蚊的持续效果为90天,对德国小蠊为80天。4.在石灰墙面按25mgai/m~2,对家蝇持续效果为50天,淡色库蚊和德国小蠊均为60天。
Objective: To observe the duration of insecticidal activity of cyhalothrin microcapsule suspension on different carriers. Methods: Four kinds of carriers were sprayed with different dosage (mg / m ~ 2) of medicinal solution on the surface of the four kinds of carriers, and the sustained effect was observed by forced contact method. The results showed that: 1. The sustained-release effect on houseflies was 90 days when treated with 20 mg ai / m 2 on glass plates; and Culex pipiens pallens and German cockroaches were 100 days. 2. In the paint plate above the same dose of housefly, Culex pipiens pallets and German cockroach sustained effects have 90 days. 3. On the cement board by 25mgai / m ~ 2, the sustained effect on housefly and Culex pipiens pallens for 90 days, for German cockroaches for 80 days. 4. In the lime wall by 25mgai / m ~ 2, the sustained effect of house flies for 50 days, Culex pipiens pallens and German cockroaches are 60 days.
