Abstract: “ZA-type” cages were used to capture cockroaches in 267 sites of 5 cities in Hainan. Species were identified and bacteria were isolated by routine method. 441 cockroaches were collected and identified as five species belonging to two genera, 75.3% being Periplaneta americana. More cockroaches were found in sewerage. Bacteria were detected from 82.4% of cockroaches, including Escherichia coli, Pseudomonas aeruginosa, Salmonella sp, Staphylococcus aureus, Shigella sp, Bacillus proteus and sort of mycetes. Therefore, the dominant species is Periplaneta americana in Hainan, and the high bacteria-carrying behavior of cockroaches indicates its importance in disease transmission.
