What is the primary attractant for flies in pollination?

• A. Nectar
• B. Scent
• C. Color
• D. Pheromones

Answer: (B)

Flies are guided mainly by smell. Many flowers that rely on flies emit strong, distinctive odors that mimic decaying organic matter or fermentation. These scent cues travel through the air and attract flies from a distance, drawing them to the flower where they can feed on nectar and pollinate. Nectar itself is the reward the fly gets after landing, not the initial lure, and color can help at close range but isn’t as effective at attracting flies from afar. Pheromones are signals used within insect species, not typical attractants flowers use to lure pollinators. So scent is the primary attractant for flies in pollination.
