2014年广西桂林市主要病媒生物监测分析

Investigation on main medical vectors in Guilin City in 2014

目的调查广西壮族自治区桂林市蚊、蝇、鼠、蟑螂4类病媒生物的种类、数量、分布及季节消长,为防治工作提供参考。方法依据2009年国家病媒生物密度监测方法,成蚊密度调查采用灯诱法,蝇类密度调查采用笼诱法,鼠密度调查采用夹夜法,蟑螂密度调查采用粘捕法。结果蚊类有4种,平均密度为1.76只/(灯·h),淡色库蚊为优势种,占捕获总数的83.2%;蝇类有5种,平均密度为5.6只/笼,家蝇为优势种,占捕获总数的37.0%;平均鼠密度为0.1%,捕获的鼠类均为褐家鼠;蟑螂有2种,平均蟑密度为0.9只/张,仅有1只为黑胸大蠊,其余均为德国小蠊。结论广西桂林市蚊虫控制的重点在牲畜棚和农户家,主要以淡色库蚊为主。蝇类的控制重点为农贸市场和餐饮场所的家蝇,鼠类为餐饮业的褐家鼠,蟑螂为农贸市场和餐饮场所的德国小蠊。

Objective To investigate the species, quantity, distribution and seasonal dynamics of mosquitoes, flies, mice and cockroaches in Guilin City. Methods Light trapping; cage trapping, night mouse trapping and sticky trapping were used to catch adult mosquitoes, flies, rodents and cockroaches based on the ＂Surveillance methods for vector density＂. Results The captured mosquitoes consisted of 4 species, and the average density was 1.76 pieces/（ lamp · h）. Culex pipiens pallens was the dominant species accounting for 83.2%. The caught flies consisted of 5 species with the average density of 5.6 pieces/cage, and Musca domestica was the dominant species accounting for 37.0%. All of the caught rodents were Rattus norvegicus with the average density of 0. 1%. The caught cockroaches included 2 species with the average density of 0. 9 pieces/sheet, all of cockroaches caught were the Blattella germanica except one Periplaneta fuliginosa. Conclusion Prevention and control measures should be focus on Culex pipiens pallens at livestock barns and homes of peasants,Musca domestica at seafood and meat market or small catering company,Rattus norvegicus at meat processing place and Blattella germanica at terminal market or small catering company.
