Abstract
Graphene, a recently discovered material with a unique two-dimensional (2D) structure, has shown insecticidal properties similar to inert dust protectants. However, its effectiveness as a surface treatment in food storage and processing facilities remains largely unexplored. In this study, we evaluated graphene powders applied at two doses (0.5 and 1 g/m2) on three different surfaces—metallic, concrete, and ceramic—against adults of the red flour beetle, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), and the saw-toothed grain beetle, Oryzaephilus surinamensis (L.) (Coleoptera: Silvanidae). After 7 days of exposure, O. surinamensis exhibited 100 % mortality across all surfaces and both graphene doses, while T. castaneum required 14 days to reach 100 % mortality under the same conditions. Statistical analyses confirmed that surface type did not significantly influence graphene's insecticidal activity beyond the first day of exposure. The results suggest that graphene can be effectively used as a surface treatment for controlling stored-product insects, providing rapid and consistent mortality.
期刊介绍:
The Journal of Stored Products Research provides an international medium for the publication of both reviews and original results from laboratory and field studies on the preservation and safety of stored products, notably food stocks, covering storage-related problems from the producer through the supply chain to the consumer. Stored products are characterised by having relatively low moisture content and include raw and semi-processed foods, animal feedstuffs, and a range of other durable items, including materials such as clothing or museum artefacts.
