Overview

Excerpt from The Work of the Dominion Experimental Farms The study of the life history of injurious and beneficial insects carried on in laboratory, insectary, field and forest, is essential as a first step towards the formulating of effective and practicable methods for their control or destruction. It is a work, therefore, of primary importance, and consequently one to which much close attention has been given. More recently among the many methods of control is that of keep ing in check the development and spread of injurious insects by the introduction and distribution of parasitic insects. These natural means of control, as they may be called, bear much promise, and the Dominion Entomologist has already met with some success in this comparatively new sphere of work, and there is great hope that he may still be more successful in stamping out, or at all events in preventing the spread of certain insects otherwise uncontrollable.
