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 27 th to 3 rd 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).

A filed experiment was conducted to screen relative susceptibility of nine mothbean, Vigna acobitifolis varieties against two major sucking pests' viz. jassid and whitefly. It was observed that MBS 803 and RMO 4-1-6-09 were less susceptible while RMO-225 and CZM-2 were highly susceptible and remaining cultivars were moderately susceptible to jassid. Varieties VMB101 and MBS605 were found to be less susceptible while CZM-2 and RMO 3-5-70 were highly susceptible and remaining cultivars were moderately susceptible to while fly.
