Flour Beetle
Flour beetles are members of the darkling beetle genus, genera ''Tribolium (beetle), 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. 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. Flour beetles are part of the life cycle of the tapeworm ''Hymenolepis nana'', which causes hymenolepiasis in humans. 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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Confused Flour Beetle
The confused flour beetle (''Tribolium confusum''), a type of darkling beetle known as a flour beetle, is a 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. The "confused" in the beetle's name is due to it being confused with the red flour beetle, not because of its walking pattern.Baldwin R, Fasulo TR. (2010). Confused flour beetle, ''Tribolium confusum'' Jacquelin du Val, and red flour beetle, ''Tribolium castaneum'' (Herbst). ''Featured Creatures''. (15 April ...

Tribolium Castaneum
The red flour beetle (''Tribolium castaneum'') is a species of beetle in the family Tenebrionidae, the darkling beetles. It is a worldwide pest of stored products, particularly food grains, and a model organism for ethological and food safety research. Description Adult beetles are small, around 3-4mm 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." Distribution and habitat The red flour beetle is of Indo-Australian origin and less able to survive outdoors than the closely related species ''Tribolium con ...

Cereal Silo
A grain elevator is a facility designed to stockpile or store grain. In the grain trade, the term "grain elevator" also describes a tower containing a bucket elevator or a pneumatic conveyor, which scoops up grain from a lower level and deposits it in a silo or other storage facility. In most cases, the term "grain elevator" also describes the entire elevator complex, including receiving and testing offices, weighbridges, and storage facilities. It may also mean organizations that operate or control several individual elevators, in different locations. In Australia, the term describes only the lifting mechanism. Before the advent of the grain elevator, grain was usually handled in bags rather than in bulk (large quantities of loose grain). Dart's Elevator was a major innovation. It was invented by Joseph Dart, a merchant, and Robert Dunbar, an engineer, in 1842 and 1843, in Buffalo, New York. Using the steam-powered flour mills of Oliver Evans as their model, they invented th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Genome
In the fields of molecular biology and genetics, 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 mitochondria and a small mitochondrial genome. Algae and plants also contain chloroplasts with a chloroplast genome. The study of the genome is called genomics. The genomes of many organisms have been sequenced and various regions have been annotated. The International Human Genome Project reported the sequence of the genome for ''Homo sapiens'' in 200The Human Genome Project although the initial "finished" sequence was missing 8% of the genome consisting mostly of repetitive sequences. With advancements in technology that could handle sequenci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tenebrio Obscurus
''Tenebrio obscurus'', or the dark mealworm beetle, is a species of darkling beetle. The larvae, when used as feeder insects for reptile and amphibian pets, are known as mini mealworm. These insects should not be confused with younger mealworms (''Tenebrio molitor'') or with the confused flour beetle ('' Tribolium confusum''), which is also occasionally used as a reptile feeder insect. Mini mealworms would probably remain largely unknown, if not for the reptile pet industry. In the search for easy to raise insects to use as food for captive reptiles and amphibians, mini mealworms have recently attracted interest as an ideal food item for smaller species. The larvae resemble very small mealworms, about ½ to ¾ inch (12 to 19 mm) in size. Once they reach adult size, the larvae pupa A pupa ( la, pupa, "doll"; plural: ''pupae'') is the life stage of some insects undergoing transformation between immature and mature stages. Insects that go through a pupal stage are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Destructive Flour Beetle
The destructive or dark flour beetle (''Tribolium destructor''), one of the species of darkling beetle known generally as flour beetles, is a common pest insect known for attacking and infesting stored flour and grain. It is a very dark brown beetle (darker than other ''Tribolium'' species) 5–6 mm long. ''T. destructor'' is found in North America, Europe and Africa. In addition to damaging flour and grain, it attacks animal food pellets, rolled oats, and poultry feed.Granousky TA. 1997. ''Stored Product Pests''. ''In Handbook of Pest Control'', 8th Ed.

North American Flour Beetle
''Aphanotus brevicornis'', the North American flour beetle, is a species of flour beetle in the family Tenebrionidae. It is a pest of stored foodstuff, particularly processed grains. This species was originally described as ''Eulabis brevicornis'' by John Lawrence LeConte, LeConte, later placed in the genus ''Aphanotus'' by Thomas Lincoln Casey Jr., Casey, and further moved to ''Tribolium (beetle), Tribolium'' by H. E. Hinton, 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'' .

Hymenolepiasis
Hymenolepiasis is infestation by one of two species of tapeworm: ''Hymenolepis nana'' or '' H. diminuta''. Alternative names are dwarf tapeworm infection and rat tapeworm infection. The disease is a type of helminthiasis which is classified as a neglected tropical disease. Symptoms and signs Hymenolepiasis does not always have symptoms, but they usually are described as abdominal pain, loss of appetite, itching around the anus, irritability, and diarrhea. However, in one study of 25 patients conducted in Peru, successful treatment of the infection made no significant difference to symptoms. Some authorities report that heavily infected cases are more likely to be symptomatic. Symptoms in humans are due to allergic responses or systematic toxaemia caused by waste products of the tapeworm. Light infections are usually symptomless, whereas infection with more than 2000 worms can cause enteritis, abdominal pain, diarrhea, loss of appetite, restlessness, irritability, restless sleep ...

Hymenolepis Nana
Dwarf tapeworm (''Hymenolepis nana'', also known as ''Rodentolepis nana'', ''Vampirolepis nana'', ''Hymenolepis fraterna'', and ''Taenia nana'') is a cosmopolitan species though most common in temperate zones, and is one of the most common cestodes (a type of intestinal worm or helminth) infecting humans, especially children. Morphology As its name implies ( grc, νᾶνος, nānos – dwarf), it is a small species, seldom exceeding 40 mm long and 1 mm wide. The scolex bears a retractable rostellum armed with a single circle of 20 to 30 hooks. The scolex also has four suckers, or a tetrad. The neck is long and slender, and the segments are wider than long. Genital pores are unilateral, and each mature segment contains three testes. After apolysis, gravid segments disintegrate, releasing eggs, which measure 30 to 47 µm in diameter. The oncosphere is covered with a thin, hyaline, outer membrane and an inner, thick membrane with polar thickenings that bear sever ...

Mealworm
Mealworms are the larval form of the yellow mealworm beetle, ''Tenebrio molitor'', a species of darkling beetle. Like all holometabolic insects, they go through four life stages: egg, larva, pupa, and adult. Larvae typically measure about or more, whereas adults are generally between in length. Reproduction The mealworm beetle breeds prolifically. Males insert sperm packets with their aedeagus. Within a few days the female burrows into soft ground and lays eggs. Over her lifespan, a female will, on average, lay about 500 eggs. After 4 to 19 days the eggs hatch. During the larval stage, the mealworms feed on vegetation and dead insects and molt between each larval stage, or instar (9 to 20 instars). After the final molt, they pupate. The new pupa is whitish and turns brown over time. After 3 to 30 days, depending on environmental conditions such as temperature, it emerges as an adult beetle. Sex pheromones A sex pheromone released by male mealworms has been identified. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
