OBJECTIVE: To evaluate the effect and cost-benefit of Oncomelania snail control by plowing and planting in Jiaobei Beach of Zhenjiang City.
METHODS: In 2009, the measures of building low dike and plowing and planting were implemented in the experimental area of the east part of Jiaobei Beach, while in the control area of the west part of the beach, the molluscacide (niclosamide) was used to control snails. Then, the snail control effects and the cost-benefits of the two groups were compared.
RESULTS: In the experimental area, the density of living snails decreased by 99.75% in the year when the measures were implemented, and no living snails were found from the second year. Though that the density of living snails in the control area decreased by 70% around, it aroused again in the second year. The net cost-benefit ratios of the experimental area and the control area were 2.18 and -0.92, respectively.
CONCLUSION: Building low dike and plowing and planting in the beaches along the middle and lower reaches of the Yangtze River can effectively control snails, meanwhile, it is economic.
