2012—2014年成都双流国际机场口岸病媒生物调查

Investigation on medical vectors at Chengdu Shuangliu International Airport,2012-2014

目的了解双流国际机场病媒生物(鼠、蚊、蝇、蜚蠊)的种群组成、季节消长等情况,为病媒生物的防控提供科学依据。方法鼠类监测采用夹夜法,蚊类成蚊监测采用人工小时法、幼蚊监测采用集卵器法,蝇类监测采用笼诱法,蜚蠊监测采用粘板法。结果 2012—2014年,共捕获鼠形动物2目2科2属2种,四川短尾鼩为优势种,数量为34只(69.39%);蚊类1科4属5种,致倦库蚊为优势种,数量为961只(88.33%);蝇类4科19属31种,大头金蝇为优势种,数量为2144只(36.79%);1种蜚蠊为德国小蠊,共捕获1577只。结论应依据病媒生物的季节消长规律,加强病媒生物的防控工作。

Objective To understand the population composition,seasonal fluctuation of medical vectors（rats,mosquitoes,flies,cockroaches） at Shuangliu International Airport,and to provide the basis for the prevention and control of medical vectors. Methods The night trapping,the labor hour method,collecting eggs,cage-trapping and sticky trapping were used to collect the rat,mosquito,larviciding fly and cockroach. Results The rats captured was identified as 2 orders 2 families 2 genera 2 species,mosquitoes as 1 family 4 genera 5 species,flies as 4 families 19 genera 31species,cockroaches as 1 family 1 genus 1 species. Anourosorex squamipes,Culex pipiens quinquefasciatus,Chrysomyia megacephala and Blattella germanica were dominant species,the number was 34（69.39%）,961（88.33%）,2144（36.79%）and 1577（100.00%）,respectively. Conclusion Based on the seasonal fluctuation of medical vectors,the prevention and control of vectors should be strengthened to reduce disease transmission.
