Assessment of various packaging materials for pulse storage against pulse beetle (Callasobruchus chinensis L.)

The present investigation on “Effectiveness of Packaging Materials and Storage Containers against Pulse Beetle (Callasobruchus chinensis L.)” was carried out by conducting a laboratory experiment by using various packaging materials viz. jute bag, gunny bag, polythene bag and cloth bag seeds of black gram in association with silica (2%) at Department of Entomology, Rajasthan College of Agriculture, MPUAT, Udaipur during 2020-2021. Polythene bags with silica (2%) was found to be best effective treatment among various packaging materials against pulse beetle during storage having minimum oviposition (21.33); seed damage (3.33%) and weight loss (7.93%) followed by gunny bags with silica (2%) (35.66, 4.60% and 11.67%); cloth bags with silica (2%) (39.53, 6.10% and 13.19%); Polythene bags without silica (41.86, 6.66% and 15.09%); jute bags with silica (2%) (43.86, 8.53% and 15.12%); gunny bags without silica (97.73, 17.40% and 27.86%); cloth bags without silica (109.26, 22.26% and 31.54%) and jute bags without silica (143.53, 27.86% and 37.89%).
