目的了解和掌握东营市蟑螂种群构成及密度、季节消长变化及侵害现状,为制定科学合理的蟑螂防控策略提供科学依据。方法采用粘捕法进行监测。结果 2016年全市共捕获蟑螂4 641只,德国小蠊4 585只,占98.79%;日本大蠊11只,占0.24%;蔗蠊45只,占0.97%。蟑螂密度为3.97只/张,侵害率为23.69%。东营市优势种群为德国小廉,5月份出现小高峰,为3.42只/张;8月份达到最高峰,为5.60只/张。结论蟑螂密度及侵害率以农贸市场和小餐饮为最高。建议以环境治理为基础,应用物理、化学相结合的综合防治方法,降低蟑螂密度,控制蟑螂的侵害,减少病媒生物性传染病的传播和发生。
Objective To understand and master the population structure and density of cockroaches in Dongying City, the changes of seasons and the current situation of invasion, so as to provide a scientific basis for formulating a scientific and rational cockroach prevention and control strategy.

Conclusion Cockroach density and infringement rates are the highest in the markets of farmers and small meals. Proposed to environmental governance as the basis, the use of physical and chemical combination of integrated prevention and control methods to reduce the density of cockroaches, cockroaches control the infection and reduce vector transmission of infectious diseases and occurrence.
