Pheromones that function as alarm signals to warn conspecifics of potential hazards are known as__________________?
Show answer Hide answer
Answer: A. Alarm pheromone
Explanation
Alarm pheromones are released by insects to signal danger and warn conspecifics of hazards. Nearby colony members detect the volatile chemical signal and flee or exhibit aggression. This rapid chemical communication protects social insect colonies from approaching predators. Aphids release alarm pheromones from specialized cornicles when attacked by ladybird beetles. Volatile chemical blends disperse quickly through air currents to alert surrounding group members. Behavioral responses to alarm signals include dropping from plants or freezing in place.
Synthesized alarm pheromones find potential use in repelling agricultural pests from crops. Studying chemical ecology reveals complex defense mechanisms used by social insect species. Pest management research investigates disrupting alarm communication to enhance control efficacy. Aggregation pheromones attract both male and female insects to specific feeding sites. Sex pheromones attract potential mates over long distances for successful reproduction. Trail marking pheromones guide foraging conspecifics toward discovered food resource locations.
