Laboratory evaluation reveals that inert materials significantly reduce Sitotroga cerealella mortality, suggesting effective pest management solutions.
The investigation was carried out to evaluate the efficacy of inert materials against Sitotroga cerealella (Olivier) (Lepidoptera: Gelechidae) on stored wheat in the laboratory of the Department of Entomology, Odisha University of Agriculture and Technology, Bhubaneswar, Odisha, India, during 2021-22 at 30.25 ± 0.25ºC temperature and 75.00 ± 5.06 per cent relative humidity. All the treatments, T1- wood ash, T2- saw dust, T3- sand, T4- cow dung ash, T5- kaolinite clay, T6- diatomaceous earth and T7- silica powder, were effective in controlling the S. cerealella and were superior to T8- untreated check. The treatment T6 had shown significantly the highest mortality (81.67%) followed by T5 (73.33%) and T7 (71.67%). However, the least effective treatments were T2 (58.33%), T3 (61.67%) and T4 (65.00%).
