目的了解内江市蟑螂密度及侵害现状,为开展蟑螂综合防治提供科学依据。方法按照《全国病媒生物监测方案》和《内江市2014年病媒生物监测方案》选取监测点,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、侵害现状和季节消长调查。结果 2014年内江市共布放粘蟑纸4 320张,回收4 300张,捕获蟑螂8 032只,平均密度为1.87只/张;优势种为德国小蠊,占捕获总数的95.14%;农贸市场的蟑螂密度和侵害率均最高;蟑螂密度季节消长呈双峰型,侵害率季节消长呈单峰型,8月达到高峰。结论内江市的优势种为德国小蠊,农贸市场是蟑螂的重要生境,应加大对农贸市场环境综合治理,有效控制蟑螂密度。
Objective To understand the density and invasion status of cockroaches in Neijiang and to provide a scientific basis for the comprehensive prevention and control of cockroaches.

The dominant species was German cockroach, accounting for 95.14% of the total catches. Farmers’ market The density and infestation rate of cockroaches were the highest. The cockroach density showed a bimodal pattern in seasonal fluctuation, and the rate of encroachment rate was unimodal in August and peaked in August.
