Abstract

Objective To learn and master the mosquitoes and the flies density and seasonal fluctuation in Shenyang and to provide a technical support for arbo-infectious diseases prevention and control. Methods Light traps and fly cage were used for mosquitoes and flies respectively. Results From 2011 to 2014, a total of 8572 mosquitoes were collected, with a mean density of 4.46 mosquitoes/(lamp·hour). Culex pipiens pallens was predominant species, accounting for 73.74%. The mosquito density was the highest in barns, followed by in farmers'houses, residential areas, hospitals and in parks. The mosquito density showed a marked seasonal fluctuation in Shenyang, with peak activity between July to September; from 2011 to 2014, a total of 16 119 flies were collected, with a mean density of 6.40 flies/(trap·hour), falling into 5 families, 13 genera and 14 species. Lucila sericata was predominant species, followed by Muscina stabulans, Musca domestica, Bellieria melanura, Calliphora vicina, Bercaea haemorrhoidalis, Boettcherisca peregrina; with a rising trend year by year, fly density of 2014 was 6.4 times that of 2011; fly density had peak times from June to August; the fly density was the highest in green belts, followed by in farm product markets, residential areas and in restaurants. Conclusion Data were obtained for the basic information on mosquitoes and flies density, species composition and seasonal fluctuation in Shenyang. The long term and systematic monitoring on mosquitoes and flies density should be conducted to provide a scientific basis for reasonable formulation of comprehensive prevention and control strategy.
