OBJECTIVE: To evaluate the molluscicidal effect of the buried niclosamide sustained-release method in Oncomelania snail-infested terraced environments of mountainous areas in Yunnan Province.
METHODS: A piece of relatively isolated snail-infested terraced environment was selected as experimental plot and randomly divided into four groups. The buried niclosamide sustained-release methods were performed in Group A, B, C with the doses of 6 g/m2, 12 g/m2, 24 g/m2 respectively, and Group D was sprayed with 50% niclosamide ethanolamine salt wettable powder (2 g/m2) as the control.
RESULTS: In Group C (with the buried niclosamide sustained-release method of 24 g/m2), the half-year reduction of living snail density was 89.90%, and one-year reduction of living snail density was 96.80%, which were significantly higher than those of Group D (40.35% and 59.11%) (Both P < 0.01) CONCLUSION: The buried niclosamide sustained-release method is effective and suitable for snail control in mountainous terrace areas.
