背景：在伊朗东南部疫区，室内滞留喷洒(IRS)被用作国家防治疟疾的干预措施，而溴氰菊酯可湿性粉剂是近十年来一直使用的杀虫剂之一。本研究以伊朗东南部伊兰沙尔地区斯氏按蚊为实验对象，研究了可湿性颗粒物(WG)在不同表面的残留活性。方法：采用Hudson®X-pert压缩喷雾机，将25%溴氰菊酯WG WG25 mg/m2、40 mg/m2和50 mg/m2三个剂量分别涂抹在石膏、水泥、泥浆和木质表面上，喷雾容量为10窝。结果：25%溴氰菊酯WG可湿性粉剂在不同表面的残留效果以死亡率和死亡率为依据进行评价。Stepehnsi从100%增加到70%左右。溴氰菊酯WG制剂在25、40和50mga.i./m2的剂量下，其生物药效分别为2、3和4个月。结论：AN的死亡率有一个可预期的波动。不同喷雾表面和不同剂量下的斯氏剂。在伊朗西南部的气候条件下，拟议的50毫克/平方米湿润喷雾剂是最长的4个月的喷洒活动，每年需要喷洒两次。
Background: Indoor residual spraying (IRS) is functioned as national interventions against malaria in southeastern foci of Iran and deltamethrin WP one of the insecticides have been used since past decade. In this study, the residual activity of the wettable granule (WG) was studied on different surfaces in hut scale trial against Anopheles stephensi in Iranshahr District, southeastern Iran. Methods: Three dosages of 25, 40 and 50 mg a.i./m2 of deltamethrin WG 25% formulation were applied on plaster, cement, mud, and wooden surfaces using Hudson® X-pert compression sprayer having 10 litters capacity. Results: The residual effects of deltamethrin WG 25% on different surfaces was assessed based on reduction of mortality An. stepehnsi from 100% to about 70%. At 25, 40 and 50 mg a.i./m2 the WG formulation of deltamethrin had a bioefficacy for about 2, 3 and 4 months respectively. Conclusion: There was an expectable fluctuation in mortality of An. stephensi at different sprayed surfaces as well as dosages. The proposed 50 mg/m2 WG is the longest activity for up to 4 months which needs to be applied for two spraying cycles per year at the climatically condition of southwestern Iran.
