Chemical defense of brood by a social wasp.
Ants are a constant threat to the nests of tropical social wasps. Adults of the neotropical social wasp Mischocyttarus drewseni apply a secretion to the nest stem which is repellent to ants foraging for food by scouting and recruiting, and effectively keeps them from gaining access to the nest and discovering the brood.
