摘　　要：目的了解鞍山市蟑螂种群分布及季节消长规律,掌握不同生境蟑螂侵害情况,为科学防治提供依据。方法采用粘捕法进行监测,分别在农贸市场、中小餐饮单位、宾馆、医院和居民居室内设置监测点,对粘捕到的蟑螂鉴定种类,计算蟑螂密度和侵害率。结果鞍山市蟑螂平均密度为9.04只/张,平均侵害率为23.5%。德国小蠊为绝对优势种群,占99.6%,蟑螂全年均有活动,9—11月为活动频繁期。不同生境中餐饮的蟑螂密度最高(11.24只/张),宾馆最低(2.50只/张)。侵害率农贸市场最高(64.58%),宾馆最低(1.67%)。结论鞍山市蟑螂的优势种群是德国小蠊,餐饮和农贸市场的德国小蠊密度和侵害率较高,应加强对餐饮行业和农贸市场蟑螂的监测和防治。Objective To understand the cockroach population distribution and its seasonal dynamics in Anshan City,and provide basis for scientific cockroach control. Methods Sticky trap method was adopted. Monitoring points were set in open fairs,medium and small catering units,hotels,hospitals and bedrooms of residents. The collected cockroaches were identified,and the cockroach density and infest rate were calculated. Results The average cockroach density in Anshan City was 9. 04 insects per sticky paper,and the average invasion rate was 23. 5%.Blattella germanica was the dominant population,and occupied 99. 6% of the total. Cockroach kept active around the whole year,and the frequent period was from September to November. Among different kinds of environment,the highest cockroach density was in catering units( 11. 24 insects per sticky paper),and the lowest density was in hotels( 2. 5 insects per sticky paper). The highest invasion rate was in open fairs( 64. 58%),and the lowest was in hotels( 1. 67%). Conclusion Blattella germanica was the dominant population in Anshan City,and its density and invasion rate were both high in catering units and open fairs.
