Many of the pheromones are available for both lepidopteran and beetle species. Sex and aggregation pheromones for beetles and weevils are often multiple compound complexes with optically active enantiomers. They have similar physical characteristics but their physiological effects differ. Twenty-five years of applied pheromone research and field data will be reviewed. This will include successful monitoring of pest insects and proper timing of control, mass trapping and the strategy of attract and kill. The technique of mating disruption will be discussed. Pheromones act as attractants, arrestants or repellents, thus regulating population dynamics. Their successful application depends on concentration, suitable dispensers and effective trap design. Pheromones are generally regarded as intraspecific active semiochemicals, but often times they function interspecifically as allomones or kairomones. In biological pest control kairomones are becoming more important for monitoring the presence and abundance of predators and parasitoids. The identification of a pheromone¿s chemical structure is only the beginning in understanding an odor based communication system. Many questions remain. Some of them will be addressed. |
