摘要: 目的:研制DDVP微胶囊制剂,观察其持效性。方法:(1)以DDVP原油、阿拉伯胶、明胶、聚乙烯醇5000为主要材料,采用复凝聚法制备微胶囊制剂;(2)以淡色库蚊Ⅳ龄初幼虫为试虫,采用浸液法进行微胶囊制剂持效性观察。结果:1ppm高剂量组从第10d、0.1ppm低剂量组从第5d起,微胶囊制剂的杀虫效果明显高于乳剂。结论:微胶囊制剂杀虫持效明显高于普通乳剂,药物稳定性增强。

Abstract: This paper reported the manufacture of DDVP microencapsulation preparation and continuing effect of killing insect. Four DDVP crude oil、acacia、gelatia and polyviny alcohol was used to synthetise the preparation by using compound coacervation method in laboratory. The preparation was composed of microencapsulation、suspending agents and water. The larva of Culex pipines pallens was used in the experiment of the microencapsulation preparation and emulsion's killing insect effect. Finally result, the residual effect of the microencapsulation preparation was longer than the emulsion.
