Nature  Plant Self-Defense

To protect against herbivores, wild tobacco plants deposit sweet but deadly secretions. Details

 

Program: Nature

Episode: Plant Self-Defense

To protect against herbivores the wild tobacco plant deposits trichomes, sweet treats irresistible to but also potentially fatal for leaf-eating caterpillars. Shortly after ingesting the trichomes, the insect releases a particular odor that attracts ground-foraging predators. "What Plants Talk About" premieres Wednesday, April 3 at 8/7c on PBS (check local listings).
