目的通过鼠密度监测,掌握镇江市鼠类的种群分布和季节消长情况,为科学防治鼠的危害和灭鼠提供依据。方法依据卫生部《全国病媒生物监测方案(试行)》,设城镇居民区、特殊行业和农村自然村3个类型的监测点各1个,采用中号钢板鼠夹,以生花生米为诱饵,每次布放200有效夹夜,晚放晨收。结果 5年平均鼠密度为0.56%,捕鼠6种,褐家鼠为镇江市优势鼠种,2007年鼠密度最高1.26%;2008年最低0.28%。结论镇江市口岸每年停泊上万艘船舶,监测到新的鼠种-黄毛鼠;农村因没有开展灭鼠活动,造成鼠密度很高,容易引发鼠类传染病流行性出血热发生;5年一次的“灭鼠先进城市”的复查,能控制鼠密度在一个相对低的水平。
Objective To monitor the population distribution and seasonal fluctuation of rodents in Zhenjiang by means of mouse density monitoring and provide scientific basis for prevention and control of rodent infestation. Methods According to the “National vector bio-monitoring program (for trial implementation)” of the Ministry of Health, one monitoring point was set up in each of urban residential areas, special industries and rural natural villages. The medium-sized steel rattrap was used as the bait, 200 effective layout of each clip night, morning release morning. Results The average rodent density at 5 years was 0.56%. There were 6 catches of rodents. Rattus norvegicus was the dominant species in Zhenjiang City. The highest rodent density was 1.26% in 2007 and the lowest was 0.28% in 2008. Conclusions Zhenjiang Port anchors thousands of ships each year and monitors a new rat species - Rattus rat; Rodent infestation is not carried out in rural areas, resulting in a high density of mice, which can easily lead to epidemic hemorrhagic fever with rodent disease. Five years A review of “Rodent-Advanced City” can control rat density at a relatively low level.
