Abstract: The current study was undertaken on Seasonal incidence and management of major insect-pests of groundnut during 07 July 2022 to 20 October 2022 at the experimental area Research cum Instructional Farm at RMD, CARS, Ambikapur (C. G.). The groundnut aphid, and thrips populations were found in field. Aphid and thrips population the first emergence of the pest incidence was recorded during second week of August (32nd SMW) with (0.73 aphid three leaves /plant and 0.27thrips/top bud leaves) . The population of aphid and thrips reached to its peak in 36th SMW (05 Sep.–11 Sep.) with 8.62 aphid three leaves /plant and 4.80 thrips/top bud leaves in first week of September. The correlation between aphid population and meteorological parameters, the population of aphids had a positive relationship with temperature (maximum and minimum) and relative humidity (morning) while there is a negative association between evening relative humidity and rainfall. The correlation was significant with minimum temperature.
Keywords: Aphid, Groundnut, Thrips, Weather parameters.
