【Abstract】 Objective To understand the growth and decline of mosquito density,population structure and seasonal variation in Lanzhou city,and provide scientific basis for mosquito control.Methods Mosquito lure lamp method was used.Results The average mosquito density was 3.99/(lamp·h).The mosquito densities were 3.39,1.48,6.95 and 4.74/(lamp · h) respectively in neighborhoods,hospitals,parks and livestocks.Culex accounted for96.18% of the total.The density peak appeared in August with the density of 14.27/(lamp·h).Conclusion Mosquito population structure,density fluctuation in Lanzhou city are well understood.更多还原
