Abstract
The present Investigation carried out at Students’ Instructional Farm, A. N. D. U. A. & T., Kumarganj, Ayodhya (U.P.) during Zaid, 2022. Red pumpkin beetle was first recorded during incidence initiated in the 7th SMW (3rd week of February) with a mean population 1.4 beetles per five plants which reached its peak to maximum (21.20 beetles/five plants) during 14th SMW (1st week of April). There was a weakly positive association between the red pumpkin beetle population and the minimum and maximum temperature (0.067 & 0.40), maximum rainfall and relative humidity displayed an insignificant inverse relationship (-0.467 & -0.129) while significant negative correlation with minimum relative humidity (-0.506*).
Keywords: Standard meteorological week, red pumpkin beetle, non-significant, minimum relative humidity and population
