Studies on the Seasonal Fluctuation of Gryllid Population in Barddhaman District of West Bengal

The gryllid represents the most classical type of cricket characterized by the large globular head, the tarsi compressed and the posterior tibiae armed with spines. Numerous workers like Cade (1984,1991), Cade and Wyatt (1984), Cade and Cade (1992), French and Cade (1987), Ciceran et al (1994), Doherty and Storz (1992) studied on the calling behaviour of the gryllids. Some workers like Jang and Gerhardt (2005, 2006) studied on the divergence in the calling songs between sympatric and allopatric population. Works on the population fluctuation of the gryllid fauna is very rare.
