An experimental trial was conducted to study the population dynamic of major arthropods of soybean at College of Agriculture, JNKVV, Jabalpur (MP) during Kharif season 2024-25. The result revealed that the incidence of whitefly and jassid was first observed on the crop during 29^th SW and attained its peak population during 36^th and 37^th SW, respectively. The first incidence of stem fly infestation was recorded during 30^th SW which attained its peak during 40^th SW. The first appearance of green semilooper and bihar hairy caterpillar was observed during 31^st and 32^nd SW, respectively, and reached its peak point at 38^th SW. Correlation studies between weather parameters and insect pests was revealed that whitefly and Jassids population was exhibited significantly negative correlation with evaporation whereas, the infestation of stem fly was exhibited significantly positive correlation with maximum temperature and sunshine hours while, significant negative correlation with morning and evening RH, evening vapour pressure and rainy days.
