Control has been defined as 'everything that makes life difficult for insects and tends to kill them and prevent their increase and spread over the world.' But control is not limited to insects: 'biological control' in practice not includes use of insects to control noxious plants, while various parts of the world populations of rabbits have been controlled by the virus of myxomatosis, which is also a biological phenomenon. It is suggests, ' The alteration of the balance of nature by the manipulation of biological agents so that those members of the plant and animal kingdoms that compete with man are redued to the lowest acceptable economic level'. Within this definition, this paper discusses the factors to be considered in manipulating pathogenic micro-organisms to control insects. It is not a 'review' in the generally accepted sense of the word, but uses published information to illustrate the various points. Basically, the approach is to make a comparison between pathogens and chemical insecticides, and to assess the possibilities of developing the use of pathogens to the point that they may be used in a practical way in insect control.
