The discovery may also help explain why conventional traps and insecticidal baits can sometimes have trouble controlling infestations. Newborn cockroaches learn the smell of their colony Cockroaches that had eaten the feces of their aggregation showed a strong preference for the particular pheromone that aggregation was producing. Chemical visa to the colony Can pheromones improve trap efficiency? The researchers say the finding may eventually lead to better ways to control infestations of German cockroaches. Cockroaches might be more social than you think why cockroach traps fail, how German cockroaches find their colony, how cockroach pheromones work, why cockroaches gather in groups, newborn cockroaches learn colony smell, cockroach feces used to identify colony members, using pheromones to control cockroach infestationsCockroaches may be among the least welcome visitors to houses, restaurants and hospitals, but their survival skills are surprisingly sophisticated. In new research, scientists say German cockroaches don’t only like to huddle in dark, warm places: newborns seem to learn the signature smell of their colony soon after they are born and use chemical cues in feces to find out where they belong. According to a news report by Phys Org, the discovery may also help explain why conventional traps and insecticidal baits can sometimes have trouble controlling infestations.
It also suggests that cockroaches may have a better capacity for social learning and memory than previously believed.Newborn German cockroaches, called neonates, are born without a gut microbiome. They obtain microbes and nutrients by eating feces from a communal pile in the colony’s aggregation. According to the report, researchers tested whether this exposure to feces early in their lives also affects how newborn cockroaches recognize their own group-mates.The scientists compared neonates that had ingested feces from their colony and had been exposed to its fecal odors with newborns that had not engaged in coprophagy, and were therefore microbiologically naïve. The results showed a dramatic difference. Cockroaches that had eaten the feces of their aggregation showed a strong preference for the particular pheromone that aggregation was producing. Conversely, naïve neonates showed a much wider range of responses to different fecal odors. Thus, feces consumption does more than to establish a microbiome in newborn cockroaches. It may also give them an early chemical introduction to their social group.It is mentioned that pheromones are important for bringing individuals together in aggregations of cockroaches. This chemical information can act as a sort of social ID system that allows cockroaches to find and stick with members of their group.
