目的通过监测了解黄冈市“四害”种群、密度分布及季节消长规律,为制定防制措施提供科学依据。方法鼠密度监测采用夜夹法;蚊类监测采用人工小时法;蝇类监测采用粘蝇带粘捕法;蟑螂监测采用蟑螂屋诱捕法。结果鼠密度为4%,小家鼠为优势鼠种;蚊密度为12.8,致倦库蚊和三带喙库蚊为优势蚊种;蝇密度为0.98,以家蝇为优势蝇种;蟑螂密度为0.1,主要为德国小蠊。结论为创建国家卫生城市搞好除“四害”工作提供依据。对鼠、蟑螂的防制应采取加强卫生宣传以及治理环境和化学药物并重的综合治理方针;对蚊、蝇的防制应主要采取搞好环境卫生、清除孳生地的综合治理措施。 Objective To provide a scientific basis for the development of control measures by monitoring and understanding of the population, density distribution and seasonal fluctuation pattern of Huangsi City. Methods Rat night clip method was used to monitor the density of the rats; Artificial hours method was used to monitor the mosquitoes; Sticky method to catch the flies was used to monitor flies; Cockroach house was used to monitor the cockroaches. Results Rat density was 4%, Mus musculus was the predominant species, mosquito density was 12.8, Culex quinquefasciatus and Culex tritaeniorhynchus were the dominant mosquito species, the density of flies was 0.98, Musca domestica was the predominant species, and the density of cockroaches Is 0.1, mainly for German cockroach. Conclusions provide the basis for the establishment of a national health city to do a good job of removing “four pests”. For rats and cockroaches, prevention and control measures should be taken to strengthen the health promotion and management of the environment and chemical drugs should be taken in an integrated way; prevention and control of mosquitoes and flies should be mainly taken to improve sanitation and breeding sites comprehensive control measures.
