  • Abstract Pheromones are important chemical substances for social insects. They could be used for individual recognition, group aggregation, dispersion or path direction. In this study, I used American cockroaches, of which social behavior has been documented, to test whether they could distinguish the pheromone odor of their own group. I manipulated the group composition of cockroaches by adding various number of individuals hatched from the same or different ootheca into the host group. By using the feces as the pheromone source, path and habitat selection experiments were performed to examine whether the selection was influenced by the manipulated group composition. Adding individuals hatched from different oothecae significantly reduced the correct selection rates in both experiments, and it also increased the time for decision-making in path selection experiment. The results suggest that groups containing members from multi-ootheca would lower its members’ judgment on own pheromone recognition.
