Apple maggot pheromones

Besides the obvious benefits of trapping pests, you can use traps to warn of impending infestations. If you get early warning of the appearance of apple maggots, it will prompt you to quickly hang apple maggot traps in your trees. Traps like yellow sticky traps attract insects with color other traps use chemicals produced by insects (pheromones) or plants to lure the insects to the trap.
