Book excerpt: Excerpt from Insect Parasites and Predators of Insect Pests There are certain definite limitations to the possibilities of con trol of insect pests by the use of parasites. Only in exceptional cases can complete control be achieved by this means. In the great majority of cases different degrees of partial control are secured. For this reason the introduction of parasites should be considered as supplementary to the usual methods of mechanical and chemical con trol rather than as a alternative method. The reduction in numbers of the insect pest by the use of parasites renders outbreaks less fra quent, and control is then more readily accomplished by the use of sprays or other mechanical or chemical methods.
