The field experiment was carried out at Research Instructional Farm, Rajnandgaon, Under College of Pt. Kishori Lal Shukla College of Horticulture and Research Station, Instructional Research farm, Pendri, Rajnandgaon (Chhattisgarh) during Rabi 2022-23. The studies revealed that the population of aphid noticed from last week of October (44^th SMW) to last week of January (05^th SMW). In comparison to all the month so crop period the highest activity of aphid was observed in 3^rd week of December (51 SMW) with aphid population 76.32/three leaf. The results indicated that aphid population had significantly negative correlation with, maximum temperature (r = -0.667**). Thrips population was first appeared first week of November (45^th SMW) at flowering stage to last week of January (05^th SMW) and maximum peak population was (7.30/flower) observed in second week of December (50^th SMW). The results indicated that thrips population had significantly negative correlation with, maximum temperature (r = -0.614*), while remaining weather parameters like minimum temperature, sunshine, average temperature, relative humidity, and rainfall were negatively non-significant correlated with both the insect.
