摘要/Abstract

摘要： 目的了解银川市2016－2019年蜚蠊侵害率及季节消长动态，为制定蜚蠊防制策略提供依据。方法在银川市辖的6个县（市、区）各设置1个监测点，于每年的单月中旬采用粘捕法对农贸市场、超市、宾馆、医院和居民区等环境场所开展蜚蠊密度和侵害率监测。结果 2016－2019年共捕获蜚蠊12 690只，均为德国小蠊，4年平均密度为0.82只/张、密度指数为9.66只/张、侵害率为8.41%。不同年度蜚蠊密度及侵害率以2018年最高，分别为0.95只/张和10.20%，2019年最低，分别为0.67只/张和7.21%。不同县（市、区）蜚蠊密度、侵害率均以金凤区最高，分别为1.49只/张和15.80%，其次是兴庆区，分别为1.47只/张和10.15%，贺兰县密度最低为0.11只/张，永宁县侵害率最低为4.33%。蜚蠊密度季节消长变化趋势接近双峰曲线，侵害率消长变化趋势接近单峰曲线，最高峰均分布在9月。不同环境场所蜚蠊密度、侵害率排序均以农贸市场最高，分别为2.86只/张和18.06%，居民区次之，分别为1.16只/张和17.68%，宾馆最低，为0.07只/张和2.51%。结论加强各类环境场所蜚蠊监测和防制工作，结合蜚蠊季节消长趋势，在密度高峰期前采取综合措施，以达到降低蜚蠊密度和控制疾病的目的。

Abstract: Objective To investigate the cockroach infestation rate and its seasonal variation in Yinchuan, China, from 2016 to 2019, and to provide a basis for formulating cockroach control strategies. Methods One surveillance site was set up in each of the six counties (cities) under the jurisdiction of Yinchuan. In the middle of each odd month of each year, sticks and traps were used to monitor the cockroach density and infestation rate in farmers' markets, supermarkets, hotels, hospitals, residential areas, and other environmental places. Results From 2016 to 2019, a total of 12 690 cockroaches were captured, all of which were Blattella germanjca, with a mean density of 0.82 cockroach/sheet, a density index of 9.66 cockroaches/sheet, and an infestation rate of 8.41%. The cockroach density and infestation rate were highest in 2018, being 0.95 cockroach/sheet and 10.20%, respectively, and lowest in 2019, being 0.67 cockroach/sheet and 7.21%, respectively. The highest cockroach density and infestation rate were found in Jinfeng district, being 1.49 cockroaches/sheet and 15.80%, respectively, followed by Xingqing district (1.47 cockroaches/sheet and 10.15%, respectively); Helan county had the lowest cockroach density (0.11 cockroach/sheet), and Yongning county had the lowest infestation rate (4.33%). The seasonal variation of cockroach density was close to a double-peak curve, and the variation of infestation rate was close to a single-peak curve; their highest peaks were both in September. The cockroach density and infestation rate were highest in farmers' market, being 2.86 cockroaches/sheet and 18.06%, respectively, followed by residential areas (1.16 cockroaches/sheet and 17.68%, respectively), and lowest in hotels, being 0.07 cockroach/sheet and 2.51%, respectively. Conclusion In order to reduce cockroach density and control disease, the surveillance and control of cockroaches should be strengthened in various environmental places, and comprehensive measures should be taken before the peak density period according to the seasonal variation of cockroaches.
