Study the impact of sowing periods on incidence of sucking pest revealed that the sucking pests whitefly, jassids and thrips population was significantly high during the crop sown on 1^st week of February (early sown) and recorded 0.68, 0.58 and 0.54 population per leaf, respectively, while significant lowest population recorded on crop sown during 3^rd week of February (mid late sown) and it was recorded 0.49, 0.39 and 0.38 respectively. Significant lowest population of stink bug (0.12 bugs per plant) was recorded on 4^th week of February (late sown). The interaction effect of sowing dates and varieties had no significant influence on sucking pests. Whereas, highest per cent mungbean yellow mosaic virus (MYMV) disease incidences found in early sowing as compared to late sowing and it was significant positively correlated with whitefly population.
