  "account": "Newborn German cockroaches rely on consuming their colony's feces to gain essential gut microbes and nutrients, forming social bonds through pheromones present in the fecal aggregation. Scientists discovered that neonates exposed to fecal odors in their colony displayed a stronger affinity for the specific pheromone associated with their natal group compared to naïve neonates without gut microbiomes. This finding could significantly enhance pest control efforts, as aggregation pheromones play a crucial role in cockroach colony formation and make current traps and insecticidal baits less effective. Co-author Coby Schal noted that this behavior is comparable to social insects like bees, wasps, ants, and termites, which rely on body odors rather than fecal pheromones to recognize nestmates. The research suggests that German cockroaches possess a higher capacity for learning and memory retention than previously thought, challenging the conventional understanding of their social structure.",
  "summary": "Newborn German cockroaches use pheromones in cockroach feces to identify members of their own colony and form a kind of social bond, a discovery that could be used to improve pest control efforts.",
