Interpretive Summary:

Technical Abstract: Improper or poor post-harvest handling and storage of stored grains contributes significantly to product loss, and bagged stored grain presents an option for safe storage and handling. Bagged grain is intended to maintain quality and safety, while protecting it from infestations. The objective of the research was to determine how long a suite of stored product insect species need to be exposed to a deltamethrin-treated storage bag to result in affected insects and mortality. Adults or larvae of several species of stored product insects were exposed to deltamethrin-treated packaging for time intervals ranging from 1 h to 4 weeks. The percentage of affected Prostephanus truncatus, Callosobruchus maculatus and Rhyzopertha dominica adults was < 98% after 60 minutes of exposure to treated packaging. Mortality of adult Trogoderma granarium was about 33% after 1 d of exposure, and increased to 93% after 7 d of exposure. Direct mortality of T. granarium larvae exposed to the deltamethrin-treated packaging for 8 h was about 15%, but increased to 50% when larvae were exposed for 72 h. Tribolium castaneum, Oryzaephilus surinamensis, and Trogoderma inclusum larvae continually exposed to the deltamethrin-treated packaging resulted in > 96% larval death within 1-2 weeks. The major primary stored product insects were highly susceptible to the deltamethrin-treated storage bags, but there was variation in susceptibility between species and life stages tested. The deltamethrin-treated storage bags can offer protection of bagged grain and be used as a preventative measure to reduce infestations during storage.
