Abstract:
Investigations on population dynamics of different insect pests of groundnut was carried out at Oilseeds Research Station, Latur, Maharashtra during Rabi, 2020. Studies on population dynamics of groundnut pests indicated that the leaf miner incidence prevailed during last week of November to first week of March. However its maximum activity was found during first week of January. The pest incidence was found positively influenced by morning relative humidity and evening relative humidity, while, the incidence of leaf miner was found negatively influenced by maximum temperature and wind speed. The peak activity of hairy caterpillar was in 1st SMW. The pest incidence was negatively influenced by maximum temperature and minimum temperature. The population of aphids, leafhoppers, whiteflies & thrips remained throughout the crop period with peak incidence during 1st & 10th SMW. The aphids & leafhoppers population influenced by evening & morning relative humidity. The whiteflies and thrips incidence was found positively influenced by maximum and minimum temperature while the population of predator was maximum in 1st SMW and positively correlated with morning relative humidity.
