Infestation and yield loss in chickpea due to pod borer in Bangladesh
1993
Rahman, Md. Mahbubar (Bangladesh Agricultural Research Inst., Gazipur (Bangladesh). Entomology Div.)
Pod borer (Heliothis armigera) infestation in chickpea varied widely ranging from 8.15% to 92.5% in 13 upazilas under nine districts of Bangladesh, the lowest being at Ishurdi and the highest at Lalanagar of Mirsharai. In most locations, infestations ranged from 30% to 40%. The percentage of unfilled pods ranged from 26.95 to 60.94. The yield loss due to pod borer was around 400 kg/ha in most of the upazilas, and thus the total annual grain loss for the country would amount to 2142.72 tons.
