Climate change may result in the breakdown of resistance. Climate change that facilitates the introduction of susceptible cultivars in newer regions may favor insect pests. On the contrary, chemical composition of plants may change in view of global warming, and certain insect pests may benefit from reduced host defenses; as a result climate change can also modify resistance performances of crop varieties to insect pests; it may induce increased or decreased feeding, depending on the situation and the pest. Introduction of suitable new varieties of crops or crops that take advantage of the new environmental conditions should be done with at most care and field trials. This is one of the adaptive methods suggested as a response to climate change. Cultivating suitable pest-resistant plants is critically important for feeding human generations in the future.
