本文研究了24%帕力特悬浮剂晚秋防治越冬代桑尺蠖幼虫的药效，试验结果显示：在20℃相对低温气候条件下，农药的触杀作用，喷药后3 d初步显效，喷药后10 d完全显效，药效维持20 d以上；500~1500倍药液浓度范围内，使用剂量变化对防治效果影响不明显，提高喷雾质量有助于提升除虫效果；24%帕力特悬浮剂用于越冬防治桑尺蠖的推荐使用浓度宜为1000倍左右，具体使用浓度可根据蚕期安排和用药时的天气状况及防治害虫要求的持效时间长短进行适当调整。

This paper researched the effects of 24% Palit suspension on mulberry looper lava of overwinter generation. The results showed that in 20 ℃ low temperature condition, contact toxicity of pesticides, the preliminary effect was ob-served after spraying 3 d, and completely cured after spraying 10 d, and efficacy maintained above 20 d. Between the range of 500~1500 times of the concentration, the effect of dose variation on the control effect is not obvious, and im-proving the spray quality helped to improve the pest control effect. So the recommended concentration of 24% palit sus-pension should be 1000 times for the prevention and cure of overwintering mulberry looper. And the use of specific con-centration can be adjusted according to the period arrangement, the weather condition and pest control medication re-quirements.
