INSECT BEHAVIOURAL RESPONSES TO TOXINS: PRACTICAL AND EVOLUTIONARY CONSIDERATIONS

Abstract
The behavioural responses of insects to insecticides and the relationships of these responses to physiological resistance are reviewed and discussed in terms of their potential economic importance and their genetic and evolutionary bases. In addition, responses to insecticide are compared with responses of phytophagous insects to host-produced toxins, with the discussion centring upon the genetic and evolutionary bases of these similar types of response and their possible roles in adaptation and speciation.
