Abstract:
In order to study the damage loss assessment and management of rice weevil (Sitophilus oryzae L.) in wheat and maize grains in storage, experiments were conducted in the laboratory of the Department of Entomology, Sher-e-Bangla Agricultural University, Dhaka-1207 during the period from May to October 2014. Results revealed that no loss of wheat and maize grain weight during storage was found in T2 (Naphthalene 5 g/kg of stored grains) where highest loss of grain weight was found by T3 (Neem oil 5 ml/kg of stored grains) for wheat stored grain and T5 (Black pepper 5 g/kg of stored grains) for maize stored grain. In case of mortality of rice weevil, results also indicated that T2 (Naphthalene 5 g/kg of stored grains) showed 100% mortality of rice weevil where lowest mortality was found from T3 (Neem oil 5 ml/kg of stored grains) for wheat stored grain and T5 (Black pepper 5 g/kg of stored grains) for maize stored grain.
