目的通过对内江市2011-2013年蜚蠊密度进行分析,掌握其种群结构、季节消长和不同场所密度情况,为蜚蠊防治提供科学依据。方法在市区选择3个监测点,于2011-2013年每月中旬监测1次,采用粘捕法分别在农贸市场、餐饮、宾馆、医院和居民区不同环境进行密度、种群、季节消长和场所情况调查。结果 2011-2013年内江市共布放粘蟑纸6480张,回收6480张,捕获蜚蠊22 478只,平均密度为3.47只/张;优势种为德国小蠊,占捕获总数的98.09%;蜚蠊密度的季节消长呈双峰型,4月和7月各出现一个高峰;农贸市场平均密度最高为9.68只/张。结论内江市的优势种为德国小蠊,蜚蠊孳生地广泛,农贸市场是重要生境,应加大对农贸市场环境综合治理,有效控制蜚蠊密度。
Objective To analyze cockroach density in Neijiang City from 2011 to 2013, and to understand its population structure, seasonal fluctuation and density of different places so as to provide a scientific basis for cockroach prevention and control. Methods Three monitoring points were selected in the urban area and monitored once every month in the middle of 2011-2013. Density, population, seasonal growth and location were measured in different markets of farmers’ markets, restaurants, hotels, hospitals and residential areas Situation investigation. Results In 2011-2013, a total of 6480 sheets of sticky cockroach paper were collected in Neijiang city, 6480 sheets were recovered and 22 478 cockroaches were captured with an average density of 3.47 pieces per sheet. The dominant species was German cockroach, accounting for 98.09% of the total catch. Cockroach The seasonal fluctuation of density showed a bimodal pattern, with a peak in April and July respectively; the highest average density of farmers’ markets was 9.68 / piece. Conclusion The dominant species of Neijiang City is Blattella germanica. Breeding of cockroaches is widespread. Farmers ’market is an important habitat. Comprehensive management of farmers’ market environment should be stepped up to effectively control cockroach density.
