新型软体动物毒饵研制初探

目的]研制新型有效的软体动物毒饵。方法]以同型巴蜗牛为试验对象,以玉米粉和豆粉为饵料,以淀粉为粘合剂,分别以白砂糖、酵母、巧克力作为引诱剂,制成诱饵,对同型巴蜗牛进行趋性试验。同时以巧克力为引诱剂,以金属络合物为有效成分,加入有玉米粉、豆粉、适量淀粉和水,制得不同有效浓度的毒饵,对同型巴蜗牛进行室内诱杀试验。结果]对同型巴蜗牛的趋性试验表明,在3种引诱剂中,巧克力对同型巴蜗牛有较强的引诱作用 以巧克力为引诱剂制得的毒饵对蜗牛具有明显的诱杀效果,3种浓度的毒饵（3%、6%和8%）施药3 d后,同型巴蜗牛的死亡率分别达86.11%、91.67%和94.44%。结论]用金属络合物有效成分制成的毒饵对同型巴蜗牛的毒力较高,安全性好。

Preliminary Study on Development of New Poison Baits for Mollusca

Objective] The purpose was to develop a new effective poison bait for mollusca.Method] With Bradybaena similaris as the experiment subject,cornmeal and soybean powder were selected as food,starch as binder,sugar,yeast and chocolate as attractants resp.to make the bait and the test of taxis of B.similaris to bait was carried out.At the same time,the indoor trapping and killing experiment was carried out on B.similaris with different effective concn.of poison baits which was made by using chocolate as attractants,metal complex as effective components and adding cornmeal,soybean powder,adequate starch and water.Result] The result of taxis of B.similaris to bait showed that the chocolate had strong attracting action to B.similaris.The poison bait made with chocolate as the attractant had obvious trapping effect on B.similaris.The mortality of B.similaris were 86.11%,91.67% and 94.44%,resp.after it was treated with 3 kinds of concn.of poison baits(3%,6% and 8%) for 3 d.Conclusion] The poison baits made with metal complex as effective components had higher toxicity to B.similaris and was safety.
