Rust-Red Grain Beetle (Cryptolestes ferrugineus)
Origin and Habitat:
The Rust-Red Grain Beetle is a common pest of stored grains and is found globally. It originated in North America but has spread to various regions due to international trade, infesting stored products.
Reproduction and Breeding:
These beetles undergo a complete metamorphosis, with egg, larva, pupa, and adult stages. Females lay eggs in stored grains, and the larvae feed on the internal contents of the grains.
Feeding Habits:
As a stored product pest, the larvae of Rust-Red Grain Beetles primarily feed on grains, including wheat, rice, and maize. Their feeding activities can lead to a decrease in grain quality and market value.
Hiding and Living in Stored Products:
Rust-Red Grain Beetle larvae infest stored grains, creating tunnels and feeding on the internal parts of the grains. They are adaptable to various environmental conditions, making control challenging.
Damages to Stored Products:
Infestations of Rust-Red Grain Beetles can result in significant damage to stored grains, affecting both the quantity and quality of the grains.
Control Recommendations:
Product Inspection: Regularly inspect stored grains for signs of infestation, including live beetles, larvae, damaged grains, or fine powder (frass).
Temperature Control: Implement temperature control measures in storage facilities, as Rust-Red Grain Beetles thrive in warmer conditions.
Proper Sealing: Ensure proper sealing of storage containers to prevent infestation. Repair any cracks or gaps that may serve as entry points for the beetles.
