摘要
目的了解西安市蟑螂的种群构成、生境分布、季节消长情况,为防治工作提供科学依据。方法采用粘捕法。结果共捕获蟑螂135只,德国小蠊130只,其余5只为褐斑大蠊。蟑螂平均密度为0.032只/张,平均粘捕率为1.51%。农贸市场和餐饮行业中蟑螂密度和粘捕率均较高;不同季节蟑螂密度和粘捕率分布呈单峰曲线,且峰值均在9月。城区年平均蟑螂密度低于郊区。结论农贸市场和餐饮行业仍是蟑螂侵害较高的场所,需要重点关注。
Objective To understand the population composition,seasonal dynamics and infestation of cockroaches in Xi’an,so as to provide the scientific basis for cockroach control.Methods The sticky trap method was performed for the investigation.Results A total of 135 cockroaches were captured,including 130 Blattella germanica and 5 Periplaneta brunnea.The average density of cockroaches was 0.032 cockroaches per piece,and the average adhesion rate was 1.51%.Cockroach density and adhesion rate were high in farmer’s market and catering industry.The distribution of cockroach density and adhesion rate in different seasons showed a unimodal curve,with a peak in September.The annual average cockroach density in urban areas was lower than that in suburban areas.Conclusion Farmers’markets and catering industries were still the places highly infested by cockroaches,which needed more attention.
