Abstract | Rice weevil, Sitophilus oryzae is one of the most devastating primary pests of stored grains. Adults feed mainly on endosperm, while larvae feed on germ, resulting in reduced germination and nutritional value. Rice product after wheat has special importance as the second agriculture strategic product. So in this research, the pest effect was studied with five different treatments viz, Oryza sativa (polished rice, unpolished (rough) rice), Triticum aestivum (wheat), Zea mays (maize), and Hordeum vulgare (barley), each replicated ten times. The assessed parameters were percent grain damage, percent weight loss, and number of F1 progeny produced in free choice conditions. Polished rice was the most preferred host in free-choice testing, with 18.75% grain damage, 14.11% grain weight loss, and 138.8 adult F1 progeny emergence.. Rough rice was the least preferred host under free choice condition. S. oryzae thus, preferred polished rice. |
