Study the influence of climate change on Clavigralla gibbosa (Spinola) in pigeonpea
Monitoring and population dynamics of tur pod bug, Clavigralla gibbosa in unprotected pigeonpea crop during kharif seasons from 2011 to 2014 at the Farmers field of Jurdcial area of S.D. Agricultural University, S.K. Nagar, North Gujarat, India. Temperature, rainfall and host-plant species were analyzed with respect to population fluctuation of the tur pod bug. The observations revealed that, the average number of larval population per plant in the season (from 27th to 3rd standard weeks) was 0.97, 0.32, 0.30 and 0.38 larvae per plant during 2011, 2012, 2013 and 2014 respectively. Population of C. gibbosa had significant and negative correlation with maximum temperature (r= -0.73), rainfall (r= -0.29) and relative humidity (r= -0.79, r= -0.58 morning and evening, respectively).
