Effect of solar treatment and different colours on infestation of Sitophilus oryzae (Linn.) in wheat

This work aimed to evaluate the efficiency of natural promising techniques in controlling rice weevil, Sitophilus oryzae (Linn.) the main pest of different cereals. To achieve this, the potential of solar energy to suppress rice weevil population were investigated. Effect of solar energy was evaluated using different coloured polythene bags at different exposure periods (8, 16 and 24 hrs). The colours resulted in maximum adult mortality within black colour at 24 hr exposure period. Solar energy treatment had no negative effect on germination of wheat seeds.
