Methods The sticky trap method was used to investigate the cockroach disoperation with the sweet bread bait, the sensitive layer was applied to examine its resistance. Results All captured cockroaches were Blat- tella germanica, they could live all year round in Lianyungang, and the peak of activity period was from April to Octo- ber,the highest peak in April for 8.6 pieces per one paste-paper. The density of the cockroach in catering and hospi- tals was higher than other areas, with 6.6 pieces and 4.1 pieces per one paste-paper respectively. The resistance coef- ficient to propoxur, beta-cypermethrin and acephate was 1.8,38.2 and 6.0 respectively. Conclusion The Blattella gerrnanica are the priority species groups with high proportion nymphs in Lianyungang. The Blattella germanica can live all year round with high peaks between April to October. The catering and hospitals are the key areas for preven- tion and treatment. The Blattella germanica is middle resistance to propoxur, beta-cypermethrin and acephate, and they are quite sensitive to propoxur.
