Insect pest control.

Abstract

Elaboration of methods for the control of insect pests is not merely a question of the haphazard use of insecticides, the action of which can only be more or less guessed, but, demands a considerable amount of careful detailed study of the life history and habits of each pest before any question of the method of control to be used can be raised. There are certain broad lines of control that may be applicable to certain groups of insects, but variations in habit and local conditions will often necessitate adaptation of such to special cases.
