Online published on 27 July, 2018. Abstract The field experiment on the population dynamics of pigeonpea pests carried out at the College Farm, N. M. College of Agriculture, N.A.U., Navsari during kharif 2014–15 brought out the correlation between various weather parameters and insect pests. These indicated that maximum temperature exhibited significant positive influence on the incidence of cow bug, pod bug, blue butterfly, plume moth and pod borer. Minimum temperature exhibited significant negative impact on plume moth and pod fly and significant positive impact on mite and blister beetle. Average temperature exhibited significant positive influence on cow bug, blister beetle, blue butterfly and pod borer and negative influence on pod fly population. Morning, evening and average relative humidity exhibited positive relationship with mite and leaf folder population, while, it was significantly negative with plume moth, pod borer and pod fly populations.
