Abstract:
The present investigation was carried out during the Kharif crop season 2017-18 and 2018-19 at the Vegetable Research Centre, GBPUA&T, Pantnagar. The incidence of B. tabaci on brinjal was slightly higher in 2018-19 (8.00±0.18 adults/three leaves) as compared to 2017-18 (7.79±0.19 adults/three leaves). Brinjal whitefly populations showed a strong negative correlation with maximum temperature, minimum temperature, wind velocity, and evaporation while being positively correlated with morning relative humidity. Major factors viz., temperature (maximum and minimum), evening relative humidity, wind velocity, and evaporation influencing the B. tabaci population build-up were predicted using the PCRA technique with reasonable accuracy (R2 =0.82).
