Evaluation Of Silica-Based Dusts For The Management Of Red Flour Beetle (Triboliumcastaneumherbst) Infesting Stored Wheat Grains

📄 Project Abstract

Laboratory studies were conducted in the Entomology Laboratory of Crop Protection Department, Institute for Agricultural Research, Ahmadu Bello University, Samaru- Zaria, to evaluate the efficacies of four silica-based dust namely; Diatomaceous earth (DE), Periwinkle shell dust (PSD), Rice husk ash (RHAC), and Prawn shellash (PSA) with Pirimiphos methyl (Actellic EC) as the standard check and untreated control (which had no treatment at all) for the management of Triboliumcastaneum(Herbst) on stored wheat. The treatments were laid out in a completely randomized design (CRD) at five concentrations (0.25, 0.50, 1.00, 1.50 and 2.00g/100g of wheat grains) each repeated three times. The parameters assessed for the efficacy of the silica based dust include; adult mortality at 24, 48 and 72 hours post treatment; progeny emergence (F1 and F2), and percentage grain damage. Results obtained sowed that DE applied at 1.00and 2.00 g/100 g had hundred percent mortality. PSA had 93 % adult insect mor...
