abstract
The studies revealed that whitefly adults population reached two peaks on 37^th and 38^th Standard Meteorological Weeks (SMW i.e. 2^nd and 3^rd weeks of September) with 6.11 and 5.96 adults per leaf, whereas nymphs population was as high as 8.44 and 8.74 nymphs per leaf during 36^th and 37^th Standard Meteorological Weeks (i.e. 1^st and 2^nd weeks of September), respectively. Whitefly adults had significant positive relation with maximum temperature (r=0.728) and bright sunshine hours (r=0.808) but significant negative correlation with morning (r= -0.699), evening relative humidity (r= -0.625) and rainfall (r= -0.786) and nymphs population was found to have significant positive correlation with maximum temperature (r=0.642) and bright sunshine hours (r=0.781) but negative significant relation with morning relative humidity (-0.639) and rainfall (-0.699). All weather variables collectively accounted for 81, 69 and 65 percent variability in the adults, nymphal and natural enemies (NEs) population.
