目的了解昆山市蜚蠊种群密度、分布及季节消长情况,为防控提供科学依据。方法采用粘捕法,以鲜甜面包为诱饵(2 g/片),在城区设置相对固定的监测点,每月中旬用17 cm×10 cm的粘蟑纸调查。结果 2012年4~12月共回收粘蟑纸3 820张,阳性370张,平均侵害率为9.69%;捕获蜚蠊5 046只,平均密度为1.32只/张;德国小蠊为优势种,占捕获总数的98.77%。农贸市场的平均侵害率和平均密度均为最高,分别为30.91%和5.09只/张。蜚蠊的活动高峰期为7~10月。结论昆山市蜚蠊分布广泛,尤以农贸市场的侵害率和密度最高,应加强防控措施的落实。
Objective To understand the population density, distribution and seasonal fluctuation of cockroaches in Kunshan City, and to provide a scientific basis for prevention and control. Methods Adopt sticky catching method, take sweet bread as bait (2 g / tablet), set up a relatively fixed monitoring point in the urban area, mid-month with a sticky cockroach paper 17 cm × 10 cm investigation. Results A total of 3 820 sticky cockroach papers were collected from April to December 2012, with a positive rate of 9.69%. 5 046 cockroaches were captured with an average density of 1.32 per locus. Blattella germanica was the dominant species accounting for Capture 98.77% of the total. The average rate of violation and average density of farmers’ markets are the highest, respectively 30.91% and 5.09 / Zhang. Cockroach peak activity of 7 to 10 months.
