    Investigation on Species Composition andSeasonal Growth and Decline of Flies and Mosquitoes at ShenyangTaoxian International Airport     Zhang Bo,Zhao Jian. Shenyang Entry-exit Inspection and Quarantine Bureau,Shenyang 110016,China.

    [Abstract]   Objective  To investigate the population, density and seasonal growth anddecline of flies and mosquitoes at Shenyang Airport, and to findout methods to monitor and control medical vectors and infectiousdiseases.  Method   The curtain ensnarement and cageensnarement were used to catch mosquitoes and fliesrespectively.  Result   A total of 614 mosquitoeswere found which identified as 7 species of 3 genera in 2subfamilies. A total 1 188 flies were collected, they wereindetified as 15 species of 10 genera in 7 subfamilies. Culexpipiens palles and Aedes vexans were the dominant species ofmosquitoes, accounting for 31.92% and 29.15%, respectively. Muscinastabulans and Bellieria melanura were the dominant species offlies, accounting for 33.50% and 30.56%, respectively.  Conclusion   We found out the natural baseline backgroundand seasonal growth and decline of medical vectors at ShenyangAirport through this investigation. It is very necessary for us tomonitor and control medical vectors and infectious disease atShenyang Airport.
