Insect behavior-modifying chemicals are being used in pest management programs in two basic ways. Indirect control of pests involves the use of baited traps for detection and monitoring of populations. Pests are controlled directly through mating disruption and by drawing adults to attractive sites where they are removed from the population, either with traps or insecticides. Recent advances in combinations of behavior-modifying chemical technology and insecticides have resulted in improved pest control. Examples of techniques for employing pheromone systems and experience with various pests are discussed.
