Mating disruption of pest insects by distributing lures releasing attractive chemicals over a large area is a well known control method. However, the expense of materials, chemicals, and deployment of dispensers has often limited the use of this method. If dispensers and their deployment can be made more efficient and cheaper then the method would be even more practical. The efficacy of mating disruption methods can be explored by computer simulations and through actual experiments in the field. The cost of chemical baits, their attraction radius (effectiveness), and chemical longevity in the field are other important considerations when developing a mating disruption system. More field experiments should be attempted on large scales in diverse pest systems on this general method. The following provides an introduction and a scattering of ideas regarding this increasingly important pest management tool.
