Flour beetles are members of the darkling beetle genera Tribolium or Tenebrio. They are pests of cereal silos and are widely used as laboratory animals, as they are easy to keep. The flour beetles consume wheat and other grains, are adapted to survive in very dry environments, and can withstand even higher amounts of radiation than cockroaches.[1] They are a major pest in the agricultural industry and are highly resistant to insecticides.

The larvae of T. molitor, when full-grown, are known as mealworms; small specimens and the larvae of the other species are called mini mealworms.

Selected species[edit]

Research[edit]

In 2008, the Tribolium castaneum genome was sequenced by the Tribolium Genome Sequencing Consortium. The results were published in Nature Magazine.[2]

An experiment carried out by "MythBusters" revealed they are able to survive 1000 gray (100,000 rad), 100 times the immediate lethal dose of radiation for humans, in 10% of the cases.
