摘要

我们报告了杀虫剂spinosad商用制剂对埃塞俄比亚东部索马里地区吉吉加市发现的按蚊幼虫的药效。按照世界卫生组织的指导原则，在实验室条件下，对从与建筑工地（旱季主要的按蚊幼虫产地）相关的大型蓄水池中采集的 25 批幼虫（三龄末至四龄初）进行了测试，每批幼虫都使用了生产商推荐的杀虫剂剂量（Natular® G30，0.02 克/5 升）。接触后 24-48 小时的死亡率为 100%。结果表明，菠乐杀对疟原虫幼虫有效，这表明菠乐杀可能是一种有用的工具，可作为旨在控制埃塞俄比亚这种入侵性疟疾病媒的幼虫源管理计划的一部分。

Laboratory Evaluation of Efficacy of the Larvicide Spinosad Against AnophelesStephensi in Jigjiga, Ethiopia.

We report the efficacy of a commercial formulation of the insecticide spinosad against larvae of Anopheles stephensi populations found in the city of Jigjiga, Somali Region, eastern Ethiopia. Batches of 25 larvae (late III to early IV instars) collected from large water storage reservoirs associated with construction sites (the primary An. stephensi larval site in the dry season) were tested under laboratory conditions against each insecticide at a dose recommended by the manufacturer (Natular® G30, 0.02 g/5 liter), following World Health Organization guidelines. Mortality at 24-48 h postexposure was 100%. Results show that spinosad is effective against An. stephensi larvae and suggest that it may be a useful tool as part of larval source management plans aimed at controlling this invasive malaria vector in Ethiopia.
