Abstract

The field experiment were conducted at Agronomy farm, S.K.N. College of Agriculture, Jobner during Kharif, 2020 and 2021 to know the population dynamics of leafhopper, Empoasca kerri Pruthi and thrips, Scirtothrips dorsalis Hood on groundnut. The primary focus of research on the effects of weather variables on insect ecology. The incidence of leafhopper, E. kerri and thrips S. dorsalis appeared in the fifth and fourth week of July in both the years and the population of leafhopper and thrips reached to its peak in the second and first week of September during Kharif, 2020 and 2021 respectively. The correlation studies indicated that the leafhopper and thrips population had significant positive correlation with relative humidity (r= 0.62 and r= 0.60) and (r= 0.77 and r= 0.75) during both the Kharif seasons 2020 and 2021 respectively. Whereas the leafhopper and thrips population had significant positive correlation (r= 0.59 and r= 0.61) respectively at minimum temperature in Kharif 2021.
