Objective To master the cockroach density, infestation rate, seasonal variation, and species composition in Anhui province, China, and to provide a scientific basis for the implementation of cockroach prevention and control. Methods The sticky trap method was used for surveillance. The surveillance data of cockroaches in Anhui province from 2017 to 2019 were collected and collated, and the composition ratio of cockroaches and the density changes of cockroaches between different years and habitats were compared and analyzed. Excel 2007 and SPSS 17.0 softwares were employed to analyze the surveillance data. The F test was used to analyze the difference in cockroach density between different habitats. Results A total of 11 378 cockroaches were captured from 2017 to 2019. The dominant species was Blattella germanica (89.77%). The overall density was 0.87 cockroaches/sheet. The overall infestation rate was 10.84%. The highest cockroach density and infestation rate occurred in farmers’ markets, and the lowest occurred in hospitals. The seasonal fluctuation of cockroach density showed a double-peak curve in 2017, and showed a single-peak curve from 2018 to 2019. The highest cockroach density occurred in farmers’ markets, followed by supermarkets, catering industry, residential areas, hotels, and hospitals. There was a statistically significant difference in cockroach density between different habitats (F=3.463, P<0.05). Conclusion B. germanica is the dominant species of cockroaches in Anhui province. Farmers’ markets are the key places for cockroach prevention and control. According to the seasonal fluctuation trends in cockroach density and infestation rate in different habitats, comprehensive prevention and control measures should be taken before the peak periods to reduce cockroach density and control diseases.
