e Science Society 36 Abstract INTRODUCTION There are twenty nine orders of insects. Among them, insects of few families produce sounds for various causes, since sound production are used for sex attraction, behavioural communication, alarm communication, Aggregation & deterrent of natural enemies. The most common form of communication among the insects indicated that use some type of mechanical disturbance propagating through a medium. This includes air borne, underwater sound, substrate vibrations and water surface ripples (Greenfield, 2002). The mechanics of different types of sound producing system found in insects. Mechanical frequency ‒ multiplier of muscles to the higher frequency of the sound, are commonly used to convert the comparatively slow muscle contraction rate to the higher frequency of the sound (Bennet, 1999). The loud air borne sounds of many groups of Orthoptera and of the large cicadas among the Homoptera are well known (Alexander, 1960). In order to communicate over long distances small insects, because of the purely physical limitations of their size, would have to use very high frequency, (or) ultrasonic sounds (Mebes, 1978 and Michelsen et al., 1982). Vibrational communication is widespread in social insects and ecological interactions of the insect species that communicate using sound, water surface ripples, (or) substrate vibrations, we estimate that 92% SONIFICATION BEHAVIOUR OF INSECTS K.
