Effectiveness of management packages using neem oil and synthetic insecticides were tested against insect pest’s of mungbean at Pulses Research Center, Ishurdi, Pabna, Bangladesh in two consecutive seasons of kharif-I during 2011 and 2012. Spraying of insecticides reduced the insect pests infestation significantly. In both the years, thrips and pod borer infestation reduced significantly by spraying of synthetic insecticides, although stemfly and flea beetle infestation reduction were not comparatively significant. Spraying of Imidachloprid (Imitaf 20 SL) @ 0.5 ml/l gave the best results in reducing flower infestation, thrips population and pod borer infestation followed by Fipronil (Regent 50 SC) application. Accordingly, the highest net return and benefit were resulted from Imidachloprid treated plots followed by Fipronil. Hence, Imidachlorpid regarded as the best among three experimental chemicals for managing major insect pests in mungbean.
