abstract
The need to find more efficient and non-hazardous environment friendly pest management strategies have paved the way to the discovery of a wide range of innovative approaches in pest management. Keeping up with the latest trends in agriculture, acoustic technology can be considered a viable option for pest population management. Acoustic is the scientific study of how sounds are created and transmitted to the receiver. Since early 1900s, this technology has been applied to detect, identify and monitor some of the pest species in various countries. Acoustic methods have been widely explored either to trap/detect the insect pests or to manipulate the behavior by interrupting interspecific communication. Common acoustic devices used in pest management are microphones, ultrasonic transducer, laser doppler vibrometer and some sensors like accelerometers, piezoelectric disks and acoustic probe etc. Management of insect pests through acoustic devices has gained momentum due to their eco-friendly nature and hence the technology becomes as an ideal component of both IPM and precision farming. Although acoustics has been recognized as a highly efficient eco-friendly method of pest management, the widespread adoption of the technology has been hindered due to their relatively high cost as well as requirement of high expertise in the field. Exploration of advanced technologies in the development of more reliable and cost effective acoustic devices and their further improvement for easy handling may pave the way for their wide applicability in true sense.
