The Efficacy of Wood Vinegar Against Oncomelania hupensis lindoensis Snails Vector of Schistosomiasis

摘要

The eradication of Oncomelania hupensis lindoensis snail as the vector of schistosomiasis disease in its endemic areas is essential. The snail eradication is performed mechanically and chemically. Chemical eradication is conducted by using molluscicide, but the use of synthetic molluscicide is toxic to the environment. As an alternative solution, the eradication of infectious snail vector requires eco-friendly technology using wood vinegar. Wood vinegar is poisonous for infectious snails but, on the other hand, is advantageous for soil and plants around the habitats of the infectious snails. The objective of this study is to determine the lethal concentration of the wood vinegar against Oh. lindoensis. The type of research was true experimental. The amount of sample was determined based on Federer formula to generate 6 treatment concentrations with 4 repetitions. There were 2 control groups namely positive control and negative control in which positive control used Baylucide and negative control did not get any treatment. The concentrations of wood vinegar being used were 300 mg L~(-1), 900 mg L~(-1), 1800 mg L~(-1), 3600 mg L~(-1), 7200 mg L~(-1), and 21600 mg L~(-1). The result showed that the final test generated an LC_(50) value of 9696.2 mg L~(-1) and LC_(90) value of 210087.4 mg L-~1. It can be concluded from this study that wood vinegar is effective in killing Oh. lindoensis snail and it can be used as an alternative molluscicide against Oh. lindoensis snail.
