Abstract: Objective To investigate the infestation of bed bugs in China, and to provide a scientific basis for risk assessment and effective prevention and control of bed bugs. Methods The bed bug surveillance data were collected from the National vectors Surveillance in China in 2018. The occurrence of bed bug infestation was compared between different provinces or habitats. Results Bed bug surveillance was carried out in 13 provinces (autonomous regions, centrally administered municipalities) via field investigation and telephone survey. A total of 1 537 units were investigated on site, of which 11 had bed bug, infestation giving a positive infestation rate of 0.72%. A total of 17 332 standard rooms were investigated; among them, 31 (0.18%) had bed bugs. The habitats with the highest positive rates, in sequence, were dormitories in construction site, student dormitories, residential areas, nursing homes, and hotels. Conclusion Bed bugs are widely distributed in China, and the density of bed bugs in most areas was still at a relatively low level. The results of investigation indicated that construction site dormitories, residential areas, and student dormitories are the foci of bed bug infestation surveillance in the future.

摘要： 目的 了解我国臭虫的发生情况，为臭虫的风险评估和科学有效防控提供依据。方法 收集整理2018年我国病媒生物监测体系中臭虫监测数据，比较不同省份、不同生境类型中臭虫的发生情况。结果 共13个省（自治区、直辖市）开展了现场及电话调查臭虫监测工作，现场调查1 537个单位，有臭虫的单位11个，阳性率为0.72%；共调查17 332间标准间，监测到臭虫阳性房间31间，房间总阳性率为0.18%。臭虫房间阳性率最高的生境依次为工地宿舍、学生宿舍、居民区、养老院和旅馆。结论 臭虫在我国分布十分广泛，大部分地区臭虫密度还处于较低水平。调查结果提示，工地宿舍、居民区、学生宿舍是今后臭虫监控的重点。
