    Cockroach surveys were carried out in three provinces of the Northern region of Thailand: Chiang Mai, Chiang Rai, and Mae Hong Son, and three cities of Guangxi Province of the People's Republic of China: Nanning, Huangjiang, and Hechi. Sticky traps were used for cockroach sampling in these surveys. At least 30 houses in each province or city were randomly sampled. Traps were placed in kitchen areas for 2 nights. In Thailand, a total of 214 cockroaches was caught in 65 of 112 houses (59.4%) with an average of 1.9 cockroaches/ house. There were 5 species of cockroach caught: Periplaneta americana (32.7%), Pycnoscelis surinamensis (29%), Periplaneta australasiae (18.2%), Periplaneta brunnea (17.3%), and Periplaneta fuliginosa (2.8%). In China, a total of 198 cockroaches was caught in 67 of 99 houses (67.5%) with an average of 2 cockroaches/ house. There were 6 species of cockroaches caught: P. americana (53%), Py. surinamensis (12.6%), P. brunnea (12.1%), P. australasiae (12.1%), P. fuliginosa (9.6%), and Neostylopyga rhombifolia (0.6%). According to the surveys in this study, there were no significant differences among the number of cockroaches caught in the six locations of the two countries (p > 0.05). P. americana was the most abundant cockroach species in both countries.
