Extract

It is well known that no living organism can continue to multiply indefinitely. Sooner or later environmental factors combine to slow down the rate of increase and eventually bring it to a halt. This is the phenomenon we call “natural control”. Among the environmental factors responsible for the natural control of insect pests, parasitic and predacious insects sometimes play an important part.
