目的了解龙海市家栖鼠及其寄生蚤的数量分布和种群构成情况,为鼠疫防治提供科学依据。方法采取笼日法,对捕获鼠类及检获蚤类进行鉴定并计算各类指数。结果 2012-2014年总共捕获鼠类689只,其中褐家鼠282只、黄胸鼠260只、臭鼩鼱87只、小家鼠35只、黄毛鼠25只。家栖鼠密度为7.85%。染蚤鼠数141只,检获蚤类425匹,染蚤率为20.46%,总蚤指数0.62。结论龙海市的家栖鼠种主要为褐家鼠和黄胸鼠,主要蚤种为印鼠客蚤,未发现鼠间鼠疫流行迹象,但黄胸鼠密度超出鼠疫控制指标,需引起高度重视。
Objective To understand the population distribution and population composition of domestic rats and their parasitic fleas in Longhai and provide a scientific basis for the prevention and control of plague. Methods Cage method was adopted to identify and capture various types of traps and seizures of fleas. Results A total of 689 rodents were captured in 2012-2014, of which 282 were Rattus norvegicus, 260 Rattus flavipectus, 87 stinkbugs, 35 Mus musculus and 25 rodents. Domestic rat density was 7.85%. 141 fleas were seized, 425 fleas were seized, the flea flea rate was 20.46%, and the total flea index was 0.62. Conclusion The main species of domesticated rats in Longhai are Rattus norvegicus and Rattus flavipectus, and the main flea species are Indian fleas, but no epidemic signs of plague are found, but the density of Rattus flavipectus exceeds the control index of plague, which needs great attention. .
