ABSTRACT

The field experiments were carried out during kharif 2020 and 2021 at the Agriculture Research Station research farm, Sakoli, Dist. Bhandara (Maharashtra) under Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. The findings of this study showed a considerable impact of climatic variables on the biology of sucking pests, notably the rice gundhi bug, brown plant hopper, white-backed plant hopper and green leaf hopper. In kharif 2020, the maximum population of green leaf hopper, brown plant hopper and white backed plant hopper was observed at 45th meteorological weak (2.53 nos/hill), 43rd MW (1.33 nos/hill) and 46th (3.53 nos/hill), respectively. In kharif 2021, the green leaf hopper reached its peak level during at 41st meteorological week (1.67 nos/hill), and the brown plant hopper attained its peak at the 44th meteorological week (9.60 nos/hill), while the maximum population of white backed plant hopper was observed at 43rd meteorological weak (1.33 nos./hill). In contrast, the incidence of the gundhi bug was the highest at 45th (0.27 nos./hill) and 41st meteorological week (0.23 nos./hill) in kharif 2021 and 2022, respectively. Additionally, there was a strong relationship between the investigated pest population and other environmental variables, including maximum temperature, minimum temperature, relative morning humidity, relative evening humidity, rainfall and the number of days with rain during both seasons.
