Flour beetles are members of several darkling beetle genera including Tribolium and 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.[ dubious ]

Red flour beetles infest multiple different types of products such as grains, cereals, spices, seeds, and even cake mixes. They are also very susceptible to insecticides, which makes their damage very impactful on the economy of milling industries. [2]  

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.

Female reproduction is distributed over their adult life-span which lasts about a year. Flour beetles also display pre-mating discrimination among potential mates. Female flour beetles, specifically of T. castaneum, can mate with different males and may choose more attractive males over the course of their adult life-span. [3]

Selected species

Research

In 2008, the Tribolium castaneum genome was sequenced by the Tribolium Genome Sequencing Consortium. [4]

The drugstore beetle, also known as the bread beetle, biscuit beetle, and misnamed as the biscuit weevil, is a tiny, brown beetle. It can be found infesting a wide variety of dried plant products, where it is among the most common non-weevils to be found. It is the only living member of the genus Stegobium. It belongs to the family Ptinidae, which also includes the deathwatch beetle and furniture beetle. A notable characteristic of this species is the symbiotic relationship the beetles have with the yeast they carry, which are transmitted from female to larvae through the oviduct.

<i>Habrobracon hebetor</i> Species of wasp

Habrobracon hebetor is a minute wasp of the family Braconidae that is an ectoparasitoid of several species of moth caterpillars.

The maize weevil, known in the United States as the greater rice weevil, is a species of beetle in the family Curculionidae. It can be found in numerous tropical areas around the world, and in the United States, and is a major pest of maize. This species attacks both standing crops and stored cereal products, including wheat, rice, sorghum, oats, barley, rye, buckwheat, peas, and cottonseed. The maize weevil also infests other types of stored, processed cereal products such as pasta, cassava, and various coarse, milled grains. It has even been known to attack fruit while in storage, such as apples.

Alexander Sokoloff was a biologist and geneticist who conducted genetic research on the red flour beetle Tribolium castaneum, a world-wide pest species. From 1965 to 1990 he was a Professor of Biology at California State University, San Bernardino, serving for part of that time as Department Chair.

Alphitobius diaperinus is a species of beetle in the family Tenebrionidae, the darkling beetles. It is known commonly as the lesser mealworm and the litter beetle. It has a cosmopolitan distribution, occurring nearly worldwide. It is known widely as a pest insect of stored food grain products such as flour, and of poultry-rearing facilities and it is a vector of many kinds of animal pathogens. In larval form, it is an approved novel food in the European Union, and also used as animal feed.

<i>Tenebrio</i> Genus of beetles

Tenebrio is a genus of darkling beetles. Adults are 12–18 mm (0.47–0.71 in) long and can live for 1–2 years. The larvae are minor pests, but they are also widely reared and sold as pet food.

A storage pest is an insect or other animal that damages or destroys stored food or other stored valuable organic matter. Insects are a large proportion of storage pests with each type of crop having specific insects that gravitate towards them such as the genus Tribolium that consists of insects such as Tribolium castaneum or Tribolium confusum which damage flour crops primarily.
