Question

Quizplus · Accepted Answer

The phenomenon described is secondary-pest outbreak, where the use of a pesticide can disrupt the natural balance of an ecosystem and lead to an increase in populations of other pests. The heavy use of insecticide likely killed off natural predators of the new pests, allowing them to thrive unchecked. Pesticide resistance refers to the ability of pests to evolve and become immune to pesticides. Triennial pest emergence and bounce back resurgence are not recognized terms in the field of pest management.
