The author discusses various aspects of the control of bilharziasis by the application of molluscicides, including the chemicals to be used, the preparation of molluscicidal suspensions or emulsions, the rate, season, frequency and methods of application, tests for evaluating the results of treatment, factors affecting the efficacy of molluscicides and the repopulation of snails after treatment, and the cost of molluscicidal operations. In addition, he reviews briefly some of the encouraging results obtained in the field with three of the most effective molluscicides-sodium pentachlorophenate, dinitro-cyclohexylphenol and copper sulfate-and puts forward a number of suggestions as to future research on this method of snail control.
作者讨论了通过使用杀螺剂控制血吸虫病的各个方面,包括所用化学药剂、杀螺悬浮液或乳剂的配制、施用率、季节、频率和方法、评估治疗效果的测试、影响杀螺剂效力的因素以及治疗后螺蛳的重新繁殖,还有杀螺作业的成本。此外,他简要回顾了在实地使用三种最有效的杀螺剂——五氯酚钠、二硝基环己基酚和硫酸铜——所取得的一些令人鼓舞的成果,并就这种螺蛳控制方法的未来研究提出了一些建议。
