Online Published on 11 January, 2024. Abstract The investigation was conducted to evaluate the efficacy of different plant powders against Sitotroga cerealella (Olivier) 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±0.25°C temperature and 75.00±5.06 per cent relative humidity. All the powder treatments of Azadirachta indica A. Juss leaves, Pongamia pinnata L. leaves, Ocimum basilicum L. leaves, Piper nigrum L. seeds, A. indica kernel, Allium sativum L. cloves, Allium cepa L. bulbs and Curcuma longa L. rhizome, were superior to the untreated check but the efficacy level varied. The A. indica kernel powder @ 5 g kg−1 (91.67%) was significantly superior over the rest of the treatments with the highest mortality which was at par with A. indica kernel powder @ 2.5 g kg−1 (88.30%). Whereas, the significantly lowest mortality was recorded in treatment O. basilicum powder @ 5 g kg−1 (58.33%) and O. basilicum powder @ 10 g kg−1 (40.00%).
