title: Maternal and paternal pheromones in gerbils.
abstract: Mongolian gerbil pups are attracted to maternal and parental nest odors. They approach these odors in preference to the odors of either virgin females or clean bedding. The pups do not distinguish between maternal or parental odors and odors of unfamiliar lactating females. Thus lactating female gerbils produce a maternal pheromone similar to that of rats and other rodents. Attraction to the pheromone develops by two weeks of age and persists for at least three weeks. The primary source of the pheromone is the mother's enlarged ventral scent gland. Removing this gland eliminates maternal attractiveness. Development of attraction to maternal scent gland odors depends on prior exposure to them. Pups raised by mothers lacking scent glands do not approach lactating females that have sent glands. The father's presence during development alters the responses of gerbil pups to odors of other males. Pups raised by both parents avoid odors of other pairs with young, whereas pups raised by their mothers only do not. Pups are not attracted to their father's odors.
