摘要
目的了解南京市大型超市蜚蠊侵害及种群分布等情况,探讨其防治措施,为超市蜚蠊防治提供科学依据。方法选择南京市不同方位4家大型超市,采用粘捕法调查侵害率和密度,现场鉴定蜚蠊种类并计数,了解超市不同区域的蜚蠊分布情况,并分析其原因。结果共捕获蜚蠊8894只,均为德国小蠊;超市蜚蠊侵害严重,侵害率达72.64%,密度为16.78只/张,主要分布在食源和水源丰富的库房、生鲜区、熟食区、蔬果区、食品区和面包房,百货区蜚蠊侵害程度相对较轻。结论德国小蠊已成为超市侵害的优势种,以食源和水源丰富的区域侵害最为严重;应采取综合防治措施,有效降低蜚蠊侵害率,控制其密度。
Objective To understand the infestation and population distribution of cockroaches in supermarkets in Nanjing city,providing scientific basis for the control of cockroaches in supermarkets. Methods Four large supermarkets located in different positions in Nanjing city were selected and sticky trap method was applied to determine the encroachment rate and the density of cockroaches. The cockroach species were identified with the number counted and the encroachment rate and the density of cockroaches calculated. Results A total of 8894 cockroaches, all of which were Blattella germanica, were captured. It was found that the infestation of cockroaches in the supermarkets was serious with the encroachment rate amounting to 72.64% and the density being 16.78 per piece. Cockroaches were mainly distributed in storehouse, fresh section,deli section, produce section, food section and bakery of the supermarkets, where there were food and water. But relatively light infestation was seen in the department sections.
