Abstract
The study of the impact of geographical variation and seasonal changes on the male call song structure of house cricket, Acheta domesticus (L.) has been made in the present work. We used A. domesticus male call song recordings which were made in Florida, Kentucky and New York, USA and London County in UK. With the help of computer software, we extracted the temporal and frequency components of the call songs and these parameters were then used to correlate the sound structure variation with the geographical changes as well as seasonal variations. Although, we found some minor variations in the sound pattern but these certainly suggest no definite impact on the characteristics of call songs. By searching literature, we also found additional call song recordings from other geographical zones in USA, in different seasons. These recordings also appear to confirm our results and therefore these have also been included in the present comparative studies.
