目的了解昌平区2007-2011年蝇密度动态变化情况,为科学防治提供决策依据。方法采用天幕式捕蝇笼捕蝇,以市售腐乳为诱饵诱捕6h,将捕获蝇类统一带回实验室计数,鉴定种类。结果 2007-2011年昌平区共捕蝇7623只,其中2007年蝇密度为13.03只/(笼·d),之后蝇密度逐年下降,2011年降至最低为4.56只/(笼·d);昌平区蝇密度不同年份间差异有统计学意义(F(4,100)=3.07,P=0.020);蝇种构成居前3位的优势种群依次为黑尾黑麻蝇、家蝇、厩腐蝇。结论昌平区的蝇类防制工作仍应采取以环境治理为主、化学防治为辅的综合防制措施。
Objective To understand the dynamic changes of fly density in Changping District from 2007 to 2011, and provide the basis for decision-making on scientific prevention and treatment. Methods The fly-trap catching fly was used in the method. The commercially-available fermented beancurd was used as a bait to entrap for 6 hours. The collected flies were brought back to the laboratory for counting uniformly to identify the species. Results From 2007 to 2011, there were altogether 7623 flies in Changping District, of which flies density was 13.03 / (cage · d) in 2007, and the density of flies declined year by year in 2011 and dropped to 4.56 / (cage · d) in 2011; Changping The density of flies in different years was significantly different (F (4,100) = 3.07, P = 0.020). The predominant populations of flies were black-tailed black flies, house flies and stable flies. Conclusion The prevention and control of flies in Changping District should still take the comprehensive prevention and control measures which are mainly based on environmental management and supplemented by chemical control.
