Flour Beetles
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. 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. 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'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tribolium Castaneum
The red flour beetle (''Tribolium castaneum'') is a species of beetle in the family darkling beetle, Tenebrionidae, the darkling beetles. The red flour beetle, and other closely related beetles like ''Gnatocerus cornutus'', are a worldwide pest (organism), pest of stored products, particularly food grains, and a model organism for Ethology, ethological and food safety research. Description Adult beetles are small, around 3–4 mm long (1/8 inches), of a uniform rust, brown or black color. Head and pronotum are sometimes darker than rest of body. Ecology The red flour beetle attacks stored grain and other food products including flour, cereals, pasta, biscuits, beans, and nuts, causing loss and damage. The United Nations, in a recent post-harvest compendium, estimated that ''Tribolium castaneum'' and ''Tribolium confusum'', the confused flour beetle, are "the two most common secondary pests of all plant commodities in store throughout the world."

Aphanotus Brevicornis
''Aphanotus brevicornis'', the North American flour beetle, is a species of flour beetle in the family Tenebrionidae Darkling beetle is the common name for members of the beetle family Tenebrionidae, comprising over 20,000 species in a cosmopolitan distribution. Taxonomy ''Tenebrio'' is the Latin generic name that Carl Linnaeus assigned to some flour beetles .... It is a pest of stored foodstuff, particularly processed grains. This species was originally described as ''Eulabis brevicornis'' by LeConte, later placed in the genus '' Aphanotus'' by Casey, and further moved to '' Tribolium'' by Hinton. However, phylogenetic studies have shown that ''A. brevicornis'' is more closely related to '' Latheticus oryzae'' and '' Gnatocerus cornutus'' than to other ''Tribolium'' species, therefore warranting replacement of this species in its previous, otherwise defunct, genus '' Aphanotus'' .

Tenebrionidae
Darkling beetle is the common name for members of the beetle family Tenebrionidae, comprising over 20,000 species in a cosmopolitan distribution. Taxonomy ''Tenebrio'' is the Latin generic name that Carl Linnaeus assigned to some flour beetles in his ''10th edition of Systema Naturae'' 1758–59. The name means "lover of darkness"; the English language term 'darkling' means "characterised by darkness or obscurity"; see also English 'tenebrous', figuratively "obscure, gloomy." Many Tenebrionidae species inhabit dark places; in genera such as ''Stenocara'' and ''Onymacris'', they are active by day and inactive at night. The family covers a varied range of forms, such that classification presents great difficulties. These eleven subfamilies were listed in the 2021 review by Bouchard, Bousquet, ''et al.'', updating a similar catalog from 2005.Bouchard, Patrice; Lawrence, John F.; Davies, Anthony E.; Newton, Alfred F.

Genome
A genome is all the genetic information of an organism. It consists of nucleotide sequences of DNA (or RNA in RNA viruses). The nuclear genome includes protein-coding genes and non-coding genes, other functional regions of the genome such as regulatory sequences (see non-coding DNA), and often a substantial fraction of junk DNA with no evident function. Almost all eukaryotes have mitochondrial DNA, mitochondria and a small mitochondrial genome. Algae and plants also contain chloroplast DNA, chloroplasts with a chloroplast genome. The study of the genome is called genomics. The genomes of many organisms have been Whole-genome sequencing, sequenced and various regions have been annotated. The first genome to be sequenced was that of the virus φX174 in 1977; the first genome sequence of a prokaryote (''Haemophilus influenzae'') was published in 1995; the yeast (''Saccharomyces cerevisiae'') genome was the first eukaryotic genome to be sequenced in 1996.

Tribolium Confusum
The confused flour beetle (''Tribolium confusum''), a type of darkling beetle known as a flour beetle, is a globally found, common pest insect known for attacking and infesting stored flour and grain. They are one of the most common and most destructive insect pests for grain and other food products stored in silos, warehouses, grocery stores, and homes. They engage in cannibalistic behaviors for population control and nutritional benefits. ''Tribolium confusum'' practices kin selection to improve individual fitness. Multiple chemicals have been used to manage their infestation, including pyrethrin and fungal insecticides. The "confused" in the beetle's name is due to it being confused with the red flour beetle, not because of its walking pattern.

Gnatocerus Cornutus
''Gnatocerus cornutus'', or the broadhorned flour beetle, is a common species of beetle in the Tenebrionidae family. It is distributed worldwide and is commonly found in warm, tropical regions, preferring grains, yeasts, and flours as its main diet. The total development time is about 47 days. ''G. cornutus'' is predominately found in mills as a storage pest and has a wide distribution. The beetle undergoes four developmental stages, with diet quality and larval density influencing development rates and body size. Nutrition plays a crucial role, with higher-calorie diets leading to enhanced survival and faster development. Genetics also impact traits like mandible length, regulated by specific peptides and transcription factors. Male-male competition for mates is fierce, with larger weapons indicating better fighting ability and increased reproductive success. Female mate choice varies based on competitive or non-competitive mating situations. Environmental factors like nutrition ...

Tenebrio Obscurus
''Tenebrio obscurus'', or the dark mealworm beetle, is a species of darkling beetle whose larvae are known as mini mealworms. These insects should not be confused with younger mealworms (''Tenebrio molitor'') or with the confused flour beetle (''Tribolium confusum''). ''Tenebrio obscurus'' larvae resemble very small mealworms. Larvae are cylindrical and initially white, darkening as they mature. Larvae can reach a length of . Larvae then pupate, and later emerge as small, black beetles, long. In appearance, adults are similar to the yellow mealworm. They may have a lighter brown color or appear dull rather than shiny. Mini mealworm larvae are used as a feeder insect for birds, reptile pet, reptile and amphibian pets, and zoo animals. Both ''Tenebrio obscurus'' and ''Tenebrio molitor'' are being studied for their ability to biodegrade waste polystyrene products.

Mealworm
Mealworms are the larval form of the yellow mealworm beetle, ''Tenebrio molitor'', a species of darkling beetle. The yellow mealworm beetle prefers a warmer climate and higher humidity. Male mealworm beetles release a sex pheromone to attract females to mate. ''Tenebrio molitor'' has been used in biomedical research. Mealworms can be a dietary source for animals and humans. They are also considered pests, especially to food storage. Description Like all holometabolic insects, ''T. molitor'' goes through four life stages: egg, larva, pupa, and adult. Larvae typically measure about or more. Adults are generally in length. ''T. molitor'' is dark brown or black as an adult, with larvae up to long and adults up to long. The yellow mealworm beetle can be differentiated from other beetles, due to the linear grooves that are evenly divided and run along the abdomen. The beetle has only four tarsal segments on its hind legs. Most ground beetles, which are similar in size to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
