 Plants evolved a huge and diverse weaponery against herbivory, like toxic chemicals and  mechanical defenses.

-Although such defenses do hinder herbivory, top-down control by predators is also very important to keep the population of many herbivores in check.  Oddly enough, it is well documented that plant defences can attenuate the predation pressure on herbivorous insects.

   * Predation decreases in well-protect plants because herbivores can accumulate on their own tissues the toxic compounds of plants, making the preys less edible for predators.
   * Predators are attracted by volatiles that the plant elicits when injured by herbivores. Herbivores make less injuries (e.g. less leaf chewing) in protected plants, making preys harder to be spotted by the predators.
-  * Non-consumptive predator effects((non-consumptive effects are the "costs associated with defensive changes in prey traits in response to perceived risk" ([[https://wp.vcu.edu/voneshlab/research-page/predator-prey-ecology/non-consumptive-predator-effects/|James Vonesh]]; see also [[https://www.entm.purdue.edu/ecolab/nonconsumptive_effects.php|Ian Kaplan's lab site]] ) )) may also be attenuated because the prey can perceive that the risk of attack is lower in protected plants.

 Here are some questions you may explore, but further well-grounded insights are also welcome.

   * Under which conditions protected and unprotected plants can coexist?
   * What is a more effective way to control crop pests: to plant protected varieties or to increase predator densities?
