摘要/Abstract

摘要： 目的调查广东省英德市2019年钉螺分布现状，为制定科学的控螺措施提供依据。方法通过查阅和整理有关历史资料，在现场采用单纯环境抽查或系统+环境抽查方法开展钉螺孳生情况调查，对调查结果采用Excel 2007软件进行录入，用SPSS 20.0软件进行统计分析，率的比较采用χ²检验。结果共调查英德市历史有螺村5个，钉螺可疑孳生环境808个，发现有螺环境23个，有螺面积为105 648.94 m²；活螺平均密度为2.09只/0.1 m²，平均活螺框出现率为18.50%，解剖钉螺5 413只，未发现感染性钉螺。结论英德市现有适宜钉螺孳生环境较多，需加强对可疑孳生环境的查螺建档及环境整治工作。

Abstract: Objective To investigate the distribution of Oncomelania hupensis snails in Yingde, Guangdong province, China in 2019, and to provide a basis for the formulation of scientific O. hupensis snail control measures. Methods By consulting and sorting out relevant historical data, and conducting on-site environment-based sampling or system sampling combined with environment-based sampling surveys, the breeding of O. hupensis snails was investigated. Excel 2007 software was used to enter the results of investigation. SPSS 20.0 software was used to perform the statistical analysis. The Chi-square test was used to compare the rate. Results Five villages where snails had bred in Yingde were investigated, including 808 suspected breeding habitats, among which 23 habitats were found with snails, with an area of 105 648.94 m². The mean density of living snails was 2.09 snails/0.1 m², and the mean occurrence rate of living snails was 18.50%. A total of 5 413 O. hupensis snails were dissected, and no schistosome-infected snails were found. Conclusion There are many suitable habitats for the breeding of O. hupensis snails in Yingde. It is necessary to strengthen snail investigation, filing, and environmental improvement for the suspected breeding habitats.
