To study the attraction effect of the food attractants on Oncomelania hupensis.
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.
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).
The fermented kelp shows a strong luring effect to the Oncomelania snails.
研究食物引诱剂对钉螺的引诱作用。
用发酵海带（海带）与玉米淀粉混合制备钉螺食物。将钉螺投喂该食物，分别在15、25、35℃下饲养12、24、36和48小时。同时，在25℃、土壤湿度30%或60%的条件下，用含独角莲（异叶天南星）的颗粒剂加或不加发酵海带进行灭螺效果试验。
发酵海带对钉螺的引诱率受温度影响，在任何时间点25℃时最高，35℃时最低，25℃下48小时引诱率为80.3%，高于对照组（17.0%）（P<0.01）。使用含发酵海带的独角莲组钉螺死亡率（85.3%）高于不含发酵海带组（26.8%）（P<0.05）。土壤湿度60%时的死亡率高于30%湿度时（P<0.01）。
发酵海带对钉螺有较强的引诱作用。
