OBJECTIVE: To evaluate the molluscicidal effects of 10% salt of quinoid-2', 5-dichloro-4'-nitrosalicylanilide (LDS) on Oncomelania hupensis in the fields, so as to provide the evidence for the application of LDS in the fields.
METHODS: The fields where O. hupensis density was relative high were selected as the experimental area and the different concentrations of LDS were used for molluscicidal effects with the immersion, insufflation and powdering methods, and 50% wettable powder of niclosamide ethanolamine salt (WPN) was used as the control.
RESULTS: With the immersion method for 3 days, the snail death rates of LDS (0.1, 0.2 g/m3) were lower than those of WPN (2 g/m3, P < 0.01), but the snail death rates of LDS (0.4, 0.6, 0.8 g/m3) were similar with those of WPN (2 g/m3, P > 0.05). With the insufflation and powdering methods for 7 days, the snail death rates of LDS (0.2, 0.4 g/m2) were lower than those of WPN (2 g/m2, P < 0.01), but the snail death rates of LDS (0.6, 0.8, 1.0 g/m2) were similar with those of WPN (2 g/mI2, P > 0.05).
CONCLUSION: LDS has some molluscicidal effect.
