通化市2010年病媒生物监测情况分析

Surveillance of vectors in Tonghua in 2010

目的为了解通化市蚊、蝇、蟑螂、鼠种群分布特点和季节消长。方法蚊监测:采用诱蚊灯法;蝇监测:采用诱蝇笼法;蟑螂监测:采用粘捕法;鼠监测:采用鼠夹法。结果蚊监测:共捕获成蚊2 309只,隶属3属5种,优势种刺扰伊蚊。蝇监测:全年共捕获成蝇1 373只,隶属5科17属27种,优势种家蝇、厩腐蝇、丝光绿蝇。蟑螂监测:共捕蟑螂5 850只,密度指数为2.73只/张,侵害率为17.77%。鼠监测:共捕获鼠370只,隶属1科3属3种,优势种群为褐家鼠。结论控制通化市区蚊虫孳生地,下管道将成为不容忽视的场所。应定期采取药物防治,控制其孳生繁殖。控制蝇类优势种的孳生,是控制蝇类密度重要手段和措施。各行业蟑螂侵害的防治,突出防治重点区域;并积极开展以环境治理为主的综合防治措施。开展大面积灭鼠活动的最佳时机是春季。

Objective To learn species distribution and seasonal fluctuation of mosquitoes ,flies, cockroaches and rats in Tonghua. Methods Survey mosquito density with the trap-mosquito lamp method,fly density with the trap-fly cage method,rat density with the trap method,cockroach density with the stick cockroach piate method. Results 2 309 mosquitoes were captured, which belonged to 5 species and 3 genera. The dominant species was Aedes vexans. 1 373 flies were captured, which belonged to 27species, 17genera and 5 families. The dominant species are Musca domestica, Muscina stabulans and Lucilia sericata. 370 rats were captured, which belonged to 3 species, 3 genera and 1 family. The dominant species was Rattus norvegicus. 5 850 cockroaches were captured, which were Blattella germanica in all the habitats, the cockroach density was 2.73 pieces per sticky sheet, the encroachment rate was 17.77%. Conclusion The sewer will not be ignored to control the mosquito larva breeding area. The regular drug prevention will be taken to control its breeding. It is the important means and measures to control the dominant fly species breeding. Cockroaches are controlled by the method of integrated management that mainly take environment management and control the key area in all the trade. It is the best time to carry out large area deratization in the spring.
