Abstract: Objective To rapidly evaluate the palatability of poison baits to domestic rodents, and to provide basic evidence for procuring typical poison baits for autumn rodent control in urban areas. Methods In the middle of August, the domestic rats in dominant habitats were identified as experimental subjects who were captured from places such as livestock farms, supermarkets, department of stores, restaurants and residential areas, then rats were used to rapidly determine the feeding situation for further evaluating palatability of poison baits through a stimulated field in laboratory. Results Poisonous baits consumption from experimental group No. 1 to No. 6 were at 112.81, 113.40, 116.72,101.76, 126.89, and 130.99 g in sequence, at the meantime, non-poisonous baits consumptions were at 120.24, 104.94, 117.19, 136.40, 125.14, and 128.96 g. Besides, feeding coefficients were at 0.94, 1.08, 1.00, 0.75, 1.01, and 1.02 respectively with all palatability in A level. Conclusion All 6 poison baits have a good palatability, and a combination of indexes like price, toxicity and safety should be considered to select one or several poison baits for urban rodent control in autumn. Thus, this application research can quickly evaluate the palatability of poison baits, and is suitable for promoting the development of rodent control to centers for disease control and prevention in levels of counties or cities.

摘要： 目的 快速评价家栖鼠毒饵适口性，为城区秋季灭鼠采购毒饵提供依据。方法 2016年8月中旬以在养殖场、商场、超市、餐饮店和居民区等生境捕获的优势家栖鼠作为试验鼠。通过实验室模拟现场快速测定毒饵摄食系数以评价毒饵适口性。结果 1~6号试验组毒饵消耗量分别为112.81、113.40、116.72、101.76、126.89和130.99 g，无毒基饵的消耗量分别为120.24、104.94、117.19、136.40、125.14和128.96 g，摄食系数分别为0.94、1.08、1.00、0.75、1.01和1.02，适口性全部达到A级。结论 6份毒饵适口性全部良好，可结合价格、毒力、安全性等综合指标择优选择1种或几种毒饵用于城区秋季灭鼠行动，该研究可以快速评价毒饵适口性，适宜在市（县）级疾病预防控制机构推广应用。
