A field trial was conducted to test the insecticidal action of the monolayer surface film 'Arosurf MSF' applied by knapsack sprayers, against larvae and pupae of Anopheles arabiensis Patton in a rice irrigation scheme in Western Kenya. Larval and pupal densities and the number of emerging adults were determined by dipping and emergence cages respectively. Application of the monolayer by knapsack sprayers provided good coverage. There were high daily mortalities of the fourth instar larvae, with no adult emergence from 'Arosurf MSF' treated plots compared to lower fourth instar mortalities and continuous adult emergence from untreated control plots, indicating the potential of the monolayer for control of An. arabiensis mosquitoes in rice fields.
在肯尼亚西部的一个水稻灌溉区，进行了一项田间试验，以测试用背负式喷雾器施用的单层表面膜“Arosurf MSF”对阿拉伯按蚊幼虫和蛹的杀虫作用。分别通过浸蘸法和羽化笼测定幼虫和蛹的密度以及羽化出的成虫数量。用背负式喷雾器施用单层表面膜能实现良好的覆盖。四龄幼虫的每日死亡率很高，与未处理的对照地块相比，经“Arosurf MSF”处理的地块没有成虫羽化，而对照地块四龄幼虫死亡率较低且有成虫持续羽化，这表明该单层表面膜有控制稻田中阿拉伯按蚊的潜力。
