Objective To analyze the infestation and insecticide resistance of cockroaches in Xi'an city, 2012-2015. Methods The sticky trap method was used to investigate the infestation of cockroaches, and pesticide membrane method was used to determine resistance. Results The population of cockroaches in Xi'an city was relatively steady, and consisted mainly of Blattella germanica, Periplaneta americana and P. japonica. Blattella germanica were the predominant species. The density of cockroach peaked from July to August. The resistant coefficient of B. germanica to deltamethrin, beta-cypermethrin, acephate and propoxur was 8.01, 3.18, 2.72, and 3.99 fold, respectively. Conclusion Blattella germanica was the predominant species, which developed moderate resistance to deltamethrin.
