Elongated carpet beetle

Systematic position: Attagenus elongatulus belongs to the order Coleoptera and the family Dermestidae. This insect is widely recognized as a serious pest of stored products, commonly found in warehouses, silos, and facilities where agricultural produce is kept for long periods.

Biology and development: The beetle undergoes a complete metamorphosis, passing through egg, larval, pupal, and adult stages. The larvae are particularly resilient, capable of surviving on minimal nutrition and resisting various environmental stressors. Adults are active fliers, which facilitates the rapid infestation of new areas.

Affected crops: The pest targets a variety of stored goods, including raw grain, flour, dried fruits, legumes, and vegetable seeds. Although they prefer products of animal origin, their adaptation to vegetable substrates makes them a significant threat to modern agribusiness.

Nature of damage and harmfulness: The larval stage is the most destructive, as they consume the internal parts of kernels and seeds. Their infestation results in significant weight loss of the stored material and severe contamination with frass, shed skins, and pupal cases, which compromises food safety standards.

Protection measures: Effective management relies on a combination of sanitation and chemical controls. Implementing the following practices is essential for prevention:

• Regular inspection and cleaning of all storage areas to eliminate breeding sites.
• Use of insecticides in accordance with food safety regulations.
• Maintaining low grain temperatures through aeration to inhibit larval development.
• Sealing cracks and crevices to minimize harborage points for adults and larvae.
