The application of chemical pesticides to control plant pests causes contamination of soil, air and surface and underground water, resulting in damage to non-target species and humans. Non-chemical pest control methods included physical, biological and genetic control and the broad based integrated pest management have been advocated as the ways to reduce pesticide contamination in environment. One of the physical pest control methods is the use of acoustic (sound or ultrasound) electronic devices that act as pest repellers, pest chasers, pest deterrents, disruptors of pest mating and pesticides. Scientists have identified and classified different species of insects by patterning of the bio acoustic signals that insects produce for sexual communication or react to them for escaping from the predators. Also, by emission of synthetic sound of insects, they cause disruption in the mating of insects or attract the opposite sex and capture them to reduce the population of pests. Research has shown that acoustic control can be used as an effective and low cost supplement to chemical control of pests. Some studies of acoustic control of insect pests are mentioned in this review.
