Mass control of insects: The effects on fish and wildlife
The mass control of insects carried on during the past ten years has made possible the economical suppression and, in a few instances, the near eradication of pest insect populations over widespread areas. These large operations, usually featuring the use of the airplane for applying insecticides quickly and cheaply, have proven to be the means of effectuating control programs which never could have been carried on through use of the techniques and equipment of early-day economic entomology. With the development of the methods employed in modern mass control came the introduction of new toxicants, well-adapted for use against insects because of their potency, low cost and wide availability. The present-day entomologist is thus armed with the means to carry on a control task of almost any magnitude.
