This book covers insecticide classification, formulation, mode of action, resistance, metabolism, environmental fate, and regulatory legislation. It integrates classical toxicology with physiology, biochemistry, and molecular biology. The authors discuss the formulation of pesticides and describe each type, from dusts and powders to baits and aerosols. They classify insecticides by target, chemical compound, and mechanism; evaluate toxicity testing procedures; explain pesticide uptake, action, and metabolism; and explore species differences, resistance, and interactions. The book also examines pesticides in the environment and federal and state regulatory legislation and enforcement.
