|The sounds of crickets courting and flies flying familiar to many of us, but have you heard a rice weevil larva eating inside a wheat kernel, a termite cutting a piece of wood, or a grub chewing on a root? Modern insect detection and control technology makes use of these subtle signals, sampled below.|
|Most of the sound files in this library were selected from noise-free sections of recorded signal, but you can hear some typical background noises mixed with insect sounds at I below. The insect sounds have higher frequencies and shorter durations that make them relatively easy to separate from background (see discussion in ). Several different methods have been developed to identify sounds of particular insect species, and at least one author ( ) has tested a method against multiple signals below.|

A. Stored Product Insect movement and feeding sounds recorded for insect detection and monitoring studies
