Social communication activates the circadian gene Tctimeless in Tribolium castaneum

Abstract Chemical communication via pheromones is an integral component in insect behavior, particularly for mate searching and reproduction. Aggregation pheromones, that attract conspecifics of both sexes, are particularly common and have been identified for hundreds of species. These pheromones ar...
