ABSTRACT
Pest control with insecticides is based on the probability that species differ greatly in susceptibility to toxicants and that it is possible to show selective toxicity among species, that is, controlling one without harming others in the same environment. Evidence has shown that this probability is high, even though its basis is not always understood (Terriere, 1982). In this chapter, we will compare the xenobiotic metabolizing enzyme activity of various species to learn how much this may contribute to toxicity differences.
