Answer to Question 1For best control, the life cycle of a pest to be controlled must be known. There are times
in the life cycle of a pest when it is easier to control and times when control is not
possible. Also, a pest that gets inside a plant part, such as a fruit or vegetable used for
consumption, should be controlled in the egg or first hatch stage, if possible, before the
plant is damaged, or the adult must be prevented from laying eggs in the first place.
Answer to Question 2Biological pest control means using the natural enemies of plant pests, such as diseases,
predators, or parasites, to repel, kill, or consume them. Plant pests are controlled by
naturally occurring bacteria, fungi, insects, nematodes, spiders, birds, toads and frogs,
lizards, snakes, voles, and other organisms
