Red - legged ham beetle

Necrobia rufipes

Overview:

Description: The Red-legged Ham Beetle, scientifically known as Necrobia rufipes, is a pest commonly associated with stored animal products, causing damage to stored grains, dried meats, and other protein-rich materials.

Detailed Appearance:

  • Size: Adult beetles are small, ranging from 3 to 5 mm (0.12 to 0.2 inches) in length.
  • Color: Dark brown to black with distinctive red or orange legs.
  • Features: Oval-shaped body with well-developed antennae.

Life Cycle:

  • Egg: Eggs are laid in cracks and crevices of stored products.
  • Larva: Larvae feed on stored materials, causing damage and contamination.
  • Pupa: Pupation occurs within a cocoon made of debris and materials.
  • Adult: Emerging adults continue the cycle, feeding and laying eggs.

Identification of Infestation:

  • Visible Beetles: Adult beetles may be visible on or near stored products.
  • Damage Signs: Look for boreholes, fecal pellets, and webbing in stored materials.
  • Unpleasant Odor: Infested products may emit a foul odor due to decomposition.

Management Strategies:

  • Sanitation:

    • Regularly clean and inspect storage areas, removing spilled or contaminated materials.
    • Seal cracks and crevices where beetles may lay eggs.

  • Temperature Control:

    • Keep stored products in cool, dry conditions to discourage beetle activity.
    • Consider temperature treatments to control larvae and eggs.

  • Airtight Containers:

    • Store susceptible products in airtight containers to prevent beetle access.
    • Monitor stored materials for signs of infestation regularly.

  • Biological Control:

    • Introduce predators like parasitoid wasps that target beetle eggs and larvae.
    • Maintain a diverse ecosystem in storage areas to support natural enemies.

  • Chemical Control:

    • Apply residual insecticides according to recommended guidelines.
    • Use insecticide treatments as a preventive measure during storage.

Note: Preventing and managing Red-legged Ham Beetle infestations requires a combination of sanitation, monitoring, and control measures. Implementing good storage practices is essential to protect stored products from contamination and damage. Always follow safety guidelines when using insecticides and consult with pest management professionals for specific recommendations.
