目的掌握营口市区蝇类种群构成、季节消长和不同生境蝇密度情况,为制定蝇类防控方案提供科学依据。方法诱蝇笼法。结果 2012年共捕蝇2 931只,平均密度为52.34只/笼。其中最多的3种蝇类为丝光绿蝇(1 365只,46.57%)、厩腐蝇(490只,16.72%)、亮绿蝇(284只,9.69%)。丝光绿蝇为主要优势种。7、8月为密度高峰期,密度分别为:85.13、113.50只/笼。结论在成蝇活动期间,重点防治月份为7、8月,重点防治区域为露天农贸市场,相关部门在这些区域要增加灭蝇器械,并保持环境卫生,以减少或者避免由蝇类引起的肠道传染病发生。
Objective To understand the composition, seasonal fluctuation and flies density of flies in Yingkou urban area, and to provide a scientific basis for formulating flies prevention and control programs. Method lure fly cage method. Results A total of 2 931 flies were collected in 2012, with an average density of 52.34 cages per cage. The most three species of flies were Lucilia sericata (1 365, 46.57%), Stomping flies (490, 16.72%) and bright green flies (284, 9.69%). Lime green flies as the main dominant species. July and August as the peak density, the density were: 85.13,113.50 / cage. Conclusion During the period of adult fly formation, the key prevention and control months are July and August. The key areas for prevention and control are open-air farmers’ markets. Relevant departments should increase fly-killing equipment in these areas and maintain environmental hygiene so as to reduce or avoid the intestinal Road infectious disease occurred.
