Abstract
In a field trial conducted at the District Seed Farm, Department of
Agriculture, Government of West Bengal, Burdwan, West Bengal, thirteen potato
cultivars were assessed for aphid incidence, specifically Myzus persicae
(Sulzer) and Aphis gossypii Glover (Aphididae: Hemiptera), during the Rabi
seasons from 2020-2021 to 2022-2023. The combined data indicated that aphid
activity began in the third week of December, with a peak observed in the third
week of February. The aphid population demonstrated a significant positive
correlation with maximum and minimum temperatures, temperature gradient, and
bright sunshine hours, while showing a negative correlation with maximum and
minimum humidity across all potato cultivars. Multiple regression analysis
indicated that, collectively, these weather parameters significantly explained
the variability in aphid population for the Kufri Pukhraj and Kufri Jyoti
cultivars, as reflected by the adjusted R² values.
