Seasonal Incidence and Population Dynamics of Aulacophora foveicollis on Bottle Gourd (Lagenaria siceraria M.) and Their Correlation with Abiotic Factors

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*).
