目的在以面粉和玉米渣为基饵的基础上,筛选出能够增强基饵适口性和引诱性的物质。方法试验以面粉和玉米渣为基饵,分别添加15种具有引诱性和增加适口性的物质,将其制作成蜡块,然后在1.5 m×0.7 m×0.7 m大小的鼠笼中放置,记录褐家鼠对不同蜡块的喜好程度。结果经过初筛和复筛实验,筛选出褐家鼠比较偏爱有引诱剂A、引诱剂B、小米的基饵蜡块。结论由于小米的价格较高,限制了它的使用,但是在蜡块中添加自制的引诱剂A和引诱剂B将能够增加褐家鼠的取食机率。
Objective Based on the basis of flour and corn residue, select the substances that can enhance the palatability and attractability of baits. Methods Based on flour and corn dregs, 15 kinds of materials with attractive and palatability were added respectively, which were made into wax blocks, then placed in a squirrel cage of 1.5 m × 0.7 m × 0.7 m, and recorded Rattus norvegicus on the degree of preference for different wax blocks. Results After preliminary screening and re-screening experiments, we found that Rattus norvegicus prefer the bait wax block with attractant A, attractant B and millet. Conclusion Due to the higher price of millet, which limits its use, the addition of home-made attractant A and attractant B to the block will increase the chances of feeding.
