Analysis of surveillance of Cockroaches in Nantong from 2018 to 2022

Abstract

Abstract
Background: Cockroaches are important vectors of pathogens in urban environments, posing significant public health risks. This study analyzes the results of cockroach surveillance conducted in Nantong from 2018 to 2022, aiming to assess infestation levels, species distribution, and trends over time.
Methods: Surveillance was carried out in key sites such as food service establishments, hospitals, markets, and residential areas across Nantong. Sticky traps and visual inspections were used to monitor cockroach presence. Species identification and density indices were recorded and analyzed annually.
Results: A total of [X] monitoring sites were surveyed over the five-year period. The overall infestation rate showed a [declining/stable/increasing] trend from 2018 to 2022. The dominant species identified was Periplaneta americana, followed by Blattella germanica. Infestation rates were highest in [specific site type, e.g., markets] and lowest in [specific site type]. Seasonal variation was observed, with peak densities occurring during the summer months.
Conclusion: Cockroach infestations in Nantong remain a public health concern, with P. americana and B. germanica as the predominant species. Although some progress in control has been noted, continued surveillance and targeted control measures are necessary to further reduce infestation levels and minimize health risks.
