🐞 Chemical Language of Insects
Insects communicate mainly through pheromones—chemical signals that influence behavior and physiology of other individuals of the same species.
🔥 Types of Pheromones
- Sex Pheromones: Attract mates from far away
- Alarm Pheromones: Warn colony members of danger (e.g., ants and bees)
- Trail Pheromones: Mark paths to food sources (used by ants)
- Aggregation Pheromones: Cause insects to gather in groups
⚗️ How Are Pheromones Made?
Pheromones are complex organic molecules made by specialized glands and released into the environment, often highly species-specific.
🕵️♂️ Detection
Insects detect pheromones with antennae receptors, which are extremely sensitive to tiny chemical amounts—sometimes a single molecule!
🌍 Human Use of Pheromones
Humans use synthetic pheromones in integrated pest management to trap or disrupt pest insects without harmful chemicals.
