Online published on 20 December, 2024. Abstract The study, conducted to explore the population dynamics of key insect pests (whitefly, jassid, Epilachna beetle, and pod borer) in black gram crops and their correlation with abiotic factors. Whitefly and jassid populations peaked at 2.46 leaves-3 and 0.98 leaves-3 during the 36th SMW, respectively, positively correlating with maximum/minimum temperatures and rainfall, and negatively correlating with relative humidity. Epilachna beetle populations peaked at 1.23 plant-1 during the 36th SMW, showing positive correlations with all weather parameters except minimum humidity. Pod borer populations peaked at 1.08 larvae plant-1 during the 37th SMW, negatively correlating with all weather parameters except maximum temperature. Top Keywords Population, SMW, Vigna mungo L.
