Studies on Acoustic Activity of Red Palm Weevil the Deadly Pest on Coconut Crops

In this paper, details on the techniques used towards analyzing the acoustic signals generated by Red Palm Weevil RPW are presented. Besides, the acoustic signals generated by RPW in the palm and in the laboratory have been taken for this analysis. This paper describes in detail the great significance pertaining to the analysis of acoustic signals of red palm weevil recorded. The spectrum obtained for RPW is stored for analysis. The frequency in Hz and sound level in dB for both signals are determined. The frequencies are also of low range. Adequate number of spectrum has been displayed for easy understanding. Movement of RPW signal could not be compared with that of the eating and biting signature since no evenness existed for evaluation.
