Super Worm
''Zophobas atratus'' is a species of darkling beetle, whose larvae are known by the common name superworm, kingworm, barley worm, morio worm or simply Zophobas. Superworms are common in the reptile pet industry as food, along with giant mealworms (''Tenebrio molitor'' larvae treated with juvenile hormone). The larvae resemble very large mealworms, about 50 to 60 mm (1.7–2.25 in) long when full size, but unlike mealworms, the ends of their bodies are very dark, almost resembling a black color. Once they reach sufficient maturity, the larvae pupate, emerging with a white to light brown colour; eventually darkening to black. The larvae fail to pupate if kept in a high density with many other larvae and plentiful food. Keeping ''Z. atratus'' this way is commonly used to hinder pupation. To mature the larvae, they must be isolated for about 7–10 days. They will then, upon maturation, emerge from their pupal stage as darkling beetles. ''Zophobas atratus'' is generally a ...

Johan Christian Fabricius
Johan Christian Fabricius (7 January 1745 – 3 March 1808) was a Danish zoology, zoologist, specialising in "Insecta", which at that time included all arthropods: insects, arachnids, crustaceans and others. He was a student of Carl Linnaeus, and is considered one of the most important entomologists of the 18th century, having named nearly 10,000 species of animals, and established the basis for the modern insect Biological classification, classification. Biography Johan Christian Fabricius was born on 7 January 1745 at Tønder in the Duchy of Schleswig, where his father was a doctor. He studied at the gymnasium (school), gymnasium at Altona, Hamburg, Altona and entered the University of Copenhagen in 1762. Later the same year he travelled together with his friend and relative Johan Zoëga to Uppsala University, Uppsala, where he studied under Carl Linnaeus for two years. On his return, he started work on his , which was finally published in 1775. Throughout this time, he remaine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calcium
Calcium is a chemical element with the symbol Ca and atomic number 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its heavier homologues strontium and barium. It is the fifth most abundant element in Earth's crust, and the third most abundant metal, after iron and aluminium. The most common calcium compound on Earth is calcium carbonate, found in limestone and the fossilised remnants of early sea life; gypsum, anhydrite, fluorite, and apatite are also sources of calcium. The name derives from Latin ''calx'' " lime", which was obtained from heating limestone. Some calcium compounds were known to the ancients, though their chemistry was unknown until the seventeenth century. Pure calcium was isolated in 1808 via electrolysis of its oxide by Humphry Davy, who named the element. Calcium compounds are widely used in many industries: in foods and p ...

Beetles Described In 1776
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard exoske ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tenebrioninae
Tenebrioninae is the largest subfamily of the darkling beetles (Tenebrionidae), containing flour beetles, among others. Tenebrioninae contains more than 20 tribes. Description Adults Adults are robust, mid-sized beetles that typically have elytra with some sort of corrugation on the upper side. They are typically black, dark brown or grey, and often have a satiny sheen. The body is shaped like a medication capsule or like a bullet; the legs can be short and stout or long and spindly. They eat both fresh and decaying vegetation, including vegetable produce, and several are commercially important pests of flour and other cereal products. The subfamily has been characterized as adults having mandibles with the back opposite the cutting edge, without margination and excavated opposite the molar pait; having ocelli arranged in two transverse, crescent shaped or circular groups on each side of head, and with five more or less fused lenses; having antennae with basal articles n ...

Entomophagy
Entomophagy (, from Greek ἔντομον ', 'insect', and φαγεῖν ', 'to eat') is the practice of eating insects. An alternative term is insectivory. Terms for organisms that practice entomophagy are ''entomophage'' and ''insectivore''. Entomophagy is sometimes defined to also include the eating of arthropods other than insects, such as arachnids and myriapods; eating arachnids may also be referred to as arachnophagy. In non-humans Entomophagy is widespread among many animals, including non-human primates. Animals that feed primarily on insects are called insectivores. Insects, nematodes and fungi that obtain their nutrition from insects are sometimes termed ''entomophagous'', especially in the context of biological control applications. These may also be more specifically classified into predators, parasites or parasitoids, while viruses, bacteria and fungi that grow on or inside insects may also be termed ''entomopathogenic'' (see also entomopathoge ...

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, '' Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia l ...

Polystyrene
Polystyrene (PS) is a synthetic polymer made from monomers of the aromatic hydrocarbon styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle. It is an inexpensive resin per unit weight. It is a poor barrier to oxygen and water vapour and has a relatively low melting point. Polystyrene is one of the most widely used plastics, the scale of its production being several million tonnes per year. Polystyrene can be naturally transparent, but can be colored with colorants. Uses include protective packaging (such as packing peanuts and in the jewel cases used for storage of optical discs such as CDs and occasionally DVDs), containers, lids, bottles, trays, tumblers, disposable cutlery, in the making of models, and as an alternative material for phonograph records. As a thermoplastic polymer, polystyrene is in a solid (glassy) state at room temperature but flows if heated above about 100 °C, its glass transition temperature ...

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 ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tenebrio Molitor
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. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insects As Feed
Insects as feed are insect species used as animal feed, either for livestock, including aquaculture, or as pet food. Utility Due to their nutritional profile, especially the high protein content, various types of insects can be used as feed for industrial animal production and aquaculture. An insect-based diet for farm animals has been scientifically investigated for pigs, poultry and edible fish. Insects can provide as much protein and essential amino acids for swine and poultry that can potentially replace soybean meal in a diet. Inclusion of black soldier fly larvae in a diet for fish farming gave positive effect with no difference in odor and texture. At the same time, there are challenges and disadvantages compared to established feed in terms of performance and growth. For monogastric farm animals, such as swine and poultry, replacing their conventional formula entirely with insects can result to decrease in performance and growth e.g., because insect flour may contain high ...

Exoskeleton
An exoskeleton (from Greek ''éxō'' "outer" and ''skeletós'' "skeleton") is an external skeleton that supports and protects an animal's body, in contrast to an internal skeleton ( endoskeleton) in for example, a human. In usage, some of the larger kinds of exoskeletons are known as " shells". Examples of exoskeletons within animals include the arthropod exoskeleton shared by chelicerates, myriapods, crustaceans, and insects, as well as the shell of certain sponges and the mollusc shell shared by snails, clams, tusk shells, chitons and nautilus. Some animals, such as the turtle, have both an endoskeleton and an exoskeleton. Role Exoskeletons contain rigid and resistant components that fulfill a set of functional roles in many animals including protection, excretion, sensing, support, feeding and acting as a barrier against desiccation in terrestrial organisms. Exoskeletons have a role in defense from pests and predators, support and in providing an attachment framewo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Staple Food
A staple food, food staple, or simply a staple, is a food that is eaten often and in such quantities that it constitutes a dominant portion of a standard Diet (nutrition), diet for a given person or group of people, supplying a large fraction of Food energy, energy needs and generally forming a significant proportion of the intake of other nutrients as well. A staple food of a specific society may be eaten as often as every day or every meal, and most people live on a diet based on just a small number of food staples. Specific staples vary from place to place, but typically are inexpensive or readily available foods that supply one or more of the macronutrients and micronutrients needed for survival and health: carbohydrates, proteins, fats, Mineral (nutrient), minerals, and vitamins. Typical examples include tubers and roots, grains, legumes, and seeds. Among them, cereals, legumes, tubers, and roots account for about 90% of the world's food calories intake.
