The investigation on “Seasonal incidence on insect pests of soybean (Glycine max L.)” was carried out with KDS-726 (Phule Sangam) soybean variety during kharif season of 2023–24 under field condition at Agronomy Farm, College of Agriculture, Pune, Maharashtra. Aphid peak population was found in 36^th SMW (4.19 aphids/3 leaves/plant), jassids in 39^th SMW (3.89 jassids/3 leaves/plant), thrips in 37^th SMW (6.18 thrips/3 leaves/plant) and whiteflies in 39^th SMW (7.87 whiteflies/3 leaves/plant). Leaf eating caterpillar population was observed from 36^th SMW to 42^nd SMW and it was peaked during 37^th SMW with 4.34 larvae/mrl. According to the correlation studies between weather parameters and the insect pests of soybean, only morning relative humidity (r=-0.577^*) was negatively significant with the aphid population, jassids had a significantly negative correlation with wind speed (r=-0.567^*), whiteflies showed negative and highly significant correlation with wind speed (r=-0.752^**). The thrips and leaf eating caterpillar had nonsignificant correlation with all the weather parameters.
