ABSTRACT
OBJECTIVE:
To study the attraction effect of the food attractants on Oncomelania hupensis.METHODS:
Oncomelania snail food was prepared with the fermented kelp (Laminaria japonica) mixed with corn starch. Snails were fed with the food and kept for 12, 24, 36, and 48 h at 15, 25, 35 degrees C respectively. Meanwhile, snail-killing effect was tested by granules containing jack-in-the-pulpit (Arisama heterophyllum) with or without the fermented kelp under the condition of 25 degrees C, 30% or 60% soil humidity.RESULTS:
The snail-attracting rate of the fermented kelp was affected by the temperature, highest under 25 degrees C and lowest under 35 degrees C at any time point, with a rate of 80.3% in 48 h at 25 degrees C which was higher than that of the control (17.0%) (P<0.01). The snail mortality rate in the group using jack-in-the-pulpit with fermented kelp (85.3%) was higher than that of the group without fermented kelp (26.8%) (P<0.05). The mortality under 60% of soil humidity was higher than that under 30% humidity (P<0.01).CONCLUSION:
The fermented kelp shows a strong luring effect to the Oncomelania snails.
