The incidence of whitefly & Mungbean yellow mosaic virus (MYMV) was maximum in Barisal region but lowest in Jessore region. MYMV infected leaves & plants were positively correlated with the incidence of whitefly. The highest incidence of whitefly, MYMV infection but higher yield were recorded in late Rabi season; while the lowest whitefly infestation, MYMV infection & minimum yield were recorded in Kharif II season. BU Mug-1, BU Mug-2 & BARI Mug-6 out of 10 varieties were found resistant to whitefly. Dark green color-smooth-spiny hooked hairy-leaf & higher trichome density in resistant variety BU Mug-1 were associated with lower whitefly incidence. Lower leaf moisture, nitrogen content & maximum Chlorophyll in BU Mug-1 were also associated with lower whitefly incidence. Bell Jar method was more...
