Infection experiments of Oncomelania nosophora with Rhabditis oncomelaniae were carried out both in the laboratry and the field. In the laboratry experiments, 20, 40, 80, 330, and 100 Rhabditis were infected per one snail. The infection rate of the snails with the nematodes was very high (80 to 100%), when the small sized petri dishes with filter papers and tap water were used. But the mortality of the snail was very low. In the field experiments, 15, 000 and 450, 000 nematodes were sprayed with one liter of water by the use of watering can in one square meter of the habitat of Oncomelania snails. Surveys were carried out 7, 15, and 21 days after spraying.The infection rate of the snails with this kind of Rhabditis was not so high, and decreased with time. But the mortality increased with time, though this rate was not high. The authors think that it may be possible to get desirable result by improvement of the spraying method.
