【Abstract】 Objective Study the attractant activity of faeces from different stage of Periplaneta americana and provide clues for the effective prevention of cockroach. Methods The extracts with attractant activity were extracted from female adult faeces， male adult faeces and larva faeces of P. americana by ethanol and acetone. The data was analyzed by software SAS 8.0. Results All the extracts attracted P. americana significantly. The attractant activity of extracts from high-instar nymphs faeces was the best, and the attractant rate reached 59%. The extracts from male faeces had strong attractant to high-instar nymphs with the attractant rate of 41%, and that from female faeces attracted more male adults than other development stages with the attractant rate  of  42%. Three  extracts  had  higher  attractant  to  the  larvae.  Conclusion The  faeces of P. americanav  have  aggregation pheromone which activity are different, and can do more research to control cockroach.
