Methods A total of 70 sites suitable for cockroach breeding and resting in 14 cities and towns of Liaoning province from January to December 2012 were selected for surveillance by stick-capture method. Descriptive analysis was performed on all data using Excel 2010 software. Results A total of 47 647 cockroaches were captured from 2012 to 2016. The predominant species was Blattella germanica (97.28%). The total density was 0.48 insects per sheet. The total infestation was 12.75%. The highest cockroach density and infestation appeared in farm produce market, the lowest appeared in hotels. Seasonal variations of cockroach density from 2013 to 2015 showed a single peak curve, but the trend in 2012 showed a double peak curve. Seasonal variations of farm produce markets showed a single peak curve, but the trend of restaurants and hospitals showed a double peak curve. The cockroach infestation showed a single curve over the years. The highest peaks of density and infestation occurred between July and August. Conclusion The density of cockroach showed a slight rise from 2012 to 2016, but the infestation showed a slight downward. The farm produce market should be the focus of the cockroach prevention and control. Combined with the seasonal fluctuation trend of cockroach density and infestation in different habitats, comprehensive prevention should be taken during the peak time to reduce cockroach density and control diseases they transmit. %U http://www.bmsw.net.cn/EN/10.11853/j.issn.1003.8280.2019.05.016
