Dali Bai Autonomous Prefecture Institute of Schistosomiasis Control, Dali, Yunnan 671000, China.
Objective: To evaluate the potential risk of transmission of angiostrongyliasis by common freshwater snails in Dali Bai Autonomous Prefecture, Yunnan Province, so as to provide insights into local surveillance of angiostrongyliasis.
Methods: Common freshwater snails were collected from Dali Bai Autonomous Prefecture, Yunnan Province from March to April, 2020, and identified and bred in laboratory. SD rats were infected with third-stage larvae of that were isolated from commercially available snails in Dali Bai Autonomous Prefecture, and freshwater snails were infected with the first-stage larvae of that were isolated from the feces of SD rats 39 days post-infection at room temperature.

Objective: To evaluate the molluscicidal effect of 25% wettable powder of pyriclobenzuron sulphate (WPPS) against snails in hilly schistosomiasis-endemic regions and test its toxicity to fish.
Methods: In October 2020, a snail-infested setting which had been cleared was selected in Nanjian County, Yunnan Province and divided into several blocks, and the natural snail mortality was estimated. 25% WPPS was prepared into solutions at concentrations of 1 and 2 g/L, and 25% wettable powder of niclosamide ethanolamine salt (WPNES) was prepared into solutions at a concentration of 2 g/L.

Dali Bai Autonomous Prefecture Institute of Schistosomiasis Control, Dali, Yunnan 671000, China.
Objective: To compare the effectiveness of loop-mediated isothermal amplification (LAMP) assay and microscopic examinations for detection of infections in in transmission-interrupted regions, so as to provide insights into the optimization of snail surveillance tools in these regions.
Methods: Four hilly schistosomiasis-endemic villages where transmission interruption was achieved were selected in Heqing County of Yunnan Province as the study villages, including Xinzhuang and Gule villages in hilly regions and Lianyi and Yitou villages in dam regions. Snail survey was performed by means of systematic sampling combined with environmental sampling in July 2018.
