Abstract
The present study revealed that, the maximum whitefly population observed during 24th, 36th, 3rd and 20th SMW and the MYMV incidence was highest 25th, 38th, 4th and 21st SMW in summer, kharif, rabi 2017 and summer 2018. The correlation analysis revealed that, maximum temperature was positively correlated with whitefly population at all the seasons (1.97/plant, 1.55/plant, 1.55/plant and 1.58/plant). The multiple linear regression analysis revealed that, % contribution of maximum temperature on whitefly population and MYMV disease incidence was 68% (R2 = 0.687) and 88% (R2 = 0.889) in summer 2017, 67% (R2 = 0.670) and 72% (R2 = 0.720) in kharif 2017, 79% (R2 = 0.794) and 78% (R2 = 0.785) in rabi 2017 and 70% (R2 = 0.709) and 60% (R2 = 0.605) in summer 2018.
