  • Descrição: Females of many animal species emit chemical signals that attract and arouse males for mating. For example, the major aphrodisiac pheromone of Drosophila melanogaster females, 7,11-heptacosadiene (7,11-HD), is a potent inducer of male-specific courtship and copulatory behaviors. Here, we demonstrate that a set of gustatory sensory neurons on the male foreleg, defined by expression of the ppk23 marker, respond to 7,11-HD. Activity of these neurons is required for males to robustly court females or to court males perfumed with 7,11-HD. Artificial activation of these ppk23+ neurons stimulates male-male courtship even without 7,11-HD perfuming. These data identify the ppk23+ sensory neurons as the primary targets for female sex pheromones in Drosophila. [Display omitted] ► Foreleg gustatory neurons that express ppk23 function in male courtship behavior ► ppk23+ neurons respond to the female aphrodisiac pheromone 7,11-heptacosadiene (7,11-HD) ► Thermogenetic activation of ppk23+ neurons induces male courtship without 7,11-HD Females of many animal species emit chemical signals that attract and arouse males for mating. In Drosophila melanogaster, the major female aphrodisiac pheromone is 7,11-heptacosadiene (7,11-HD). Toda, Zhao, and Dickson identify the sensory neurons on the male foreleg that detect 7,11-HD. Activity of these neurons is required for males to robustly court females or to court males that have been perfumed with 7,11-HD. Conversely, artificially activating these sensory neurons induces males to court other males, even in the absence of the female pheromone.
