Q. What are "Pheromones", recently seen in news?
Answer:
Chemical substances secreted outside the body
Notes: Indian scientists have developed a sustainable pheromone dispenser that allows controlled release, potentially reducing pest control costs. Pheromones are chemical substances secreted by an individual and detected by others of the same species, particularly in bodily secretions like sweat. They are categorized as ecto-hormones, meaning they are released outside the body. Various animals use pheromones to trigger behaviors, while some fungi and algae use them in reproduction to attract complementary cell types.
