A NEW SOUND TRAP, AND OBSERVATIONS ON THE MIGRATORY AND ACOUSTIC BEHAVIOUR OF THE FIELD CRICKETTELEOGRYLLUS COMMODUS(WALKER)

A new sound trap for capturing male and female crickets attracted to the calling song of the male is described. Major advantages of the trap are its portability and effectiveness. It was designed to operate in conjunction with a previously described cricket-song generator. The trap is compared with other designs and the acoustic and migratory behaviour of crickets revealed by sound trapping are discussed.
