  Video: Ingenious Video 10: Oversexed Moths are Ruining Apples for Everyone Mark as Favorite (2 Favorites)

  Codling moths may look harmless, but their larvae wreak havoc in orchards, burrowing into fruit and eating them from the inside out. Pesticides have always been the solution to the old “worm in the apple” problem, but pesticides kill all the insects in the field, even the good ones. Instead of pesticides, farmers may soon use pheromones, those scented chemical messages animals release at mating time. Spreading synthetic, species-specific pheromones keeps male codling moths from finding females to mate with. No mating means no eggs, no larvae, and no more bad apples. Scaling up agricultural pheromones has proved difficult, but innovative approaches to pheromone production (using yeast cells) and distribution (with the help of customized weather stations) are starting to make it happen.

  Activity: Ingenious: Oversexed Moths Are Ruining Apples for Everyone Video Questions Mark as Favorite (4 Favorites)

  In this activity, students will answer questions while watching the video Oversexed Moths are Ruining Apples for Everyone from the Ingenious series produced by the American Chemical Society. Each episode investigates a different topic related to how leading-edge chemistry is taking on the world’s most urgent issues to advance everyone’s quality of life and secure our shared future. This episode investigates how the larvae of codling moths wreak havoc in orchards—burrowing into fruit and eating them from the inside out. Scientists are developing synthetic, species-specific pheromones as an alternative to pesticides. Pheromones are scented chemical messages that animals release at mating time and can help to prevent male codling moths from finding females to mate with. No mating means no eggs, no larvae and no more bad apples!
