Abstract:
The experiments were conducted in completely randomized block design with three replications during Rabi, seasons of 2020-2021 and 2021-2022 at Student Instruction Farm (SIF) Chandra Shekhar Azad University of Agriculture & Technology, Kanpur - 208002 (U.P.). To study the seasonal incidence of pea pod borer, Etiella zinckenella Treitschke, during Rabi season 2020-2021 and 2021-2022, The population was started from third week of January 2021 & 2022 (3^rd standard meteorological week) to April 2021 & 2022 (15^th standard meteorological week) of crop. The larval population was low during January, 2021 to fourth week of January, 2021 and varied from 1.01 to 1.92 larvae/five plants. The maximum population increased and reaches its peak (15.43 larvae/5 plants) in all control plots on 26 February, 2021 (8^th standard weeks). When the maximum and minimum temperature was 28.8°C and 11.9°C, respectively, relative humidity was 57% and rainfall to the tune of nil was recorded. Second year the pest population increased and reaches its peak (16.43 larvae/five plants) on 22 February 2022 (8^th standard meteorological week). and the maximum and minimum was temperature was 27.4°C and 12.3°C, respectively, relative humidity was 64.50% and the rainfall to the tune of nil was recorded.
