Home Stored Product Entomology
Home-stored product entomology is the study of insects that infest foodstuffs stored in the home. It deals with the prevention, detection and eradication of Pest (organism), pests. This field is related to forensic entomology, as consumers who find contaminated products may choose to take legal action against the producers. Suitably qualified entomologists are likely to be able to determine the identity of contaminant species, even when no insects are found and the only evidence of infestation is the resulting damage. They should also be able to determine whether the foodstuff was contaminated before or after purchase, to determine whether the producer (rather than the consumer) is at fault. Major stored product pests Flour beetles (''Tribolium castaneum'' and ''Tribolium confusum'') Two different types of beetles are classified as flour beetles: the red flour beetle and the confused flour beetle, which have similar physical characteristics. They are flat and oval in shape and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insect
Insects (from Latin ') are Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (Insect morphology#Head, head, Thorax (insect anatomy), thorax and abdomen (insect anatomy), abdomen), three pairs of jointed Arthropod leg, legs, compound eyes, and a pair of antenna (biology), antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a insect brain, brain and a ventral nerve cord. Most insects reproduce Oviparous, by laying eggs. Insects Respiratory system of insects, breathe air through a system of Spiracle (arthropods), paired openings along their sides, connected to Trachea#Invertebrates, small tubes that take air directly to the tissues. The blood therefore does not carry oxygen; it is only partly contained in ves ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Merchant Grain Beetle
''Oryzaephilus mercator'', the merchant grain beetle, is a small, flattened beetle about 2.5mm in length. It is a common, worldwide pest of grain and grain products as well as fruit, chocolate, drugs, and tobacco. The biology of ''O. mercator'' is nearly identical with '' Oryzaephilus surinamensis'' (the sawtooth grain beetle). It can be differentiated from ''O. surinamensis'' by its larger eyes and by the shape of the head, the area just behind the eyes of ''O. mercator'' is narrower than that of ''O. surinamensis'', which has a more triangular shaped head. Unlike ''O. surinamensis'', adults are capable of flight. Life cycle Females produce from 500 to 1000 eggs in a year which are deposited within a food source. The larvae are yellowish-white with a brown head and can reach a length of up to 3mm, larvae are active and move about through a food source as they feed. Larvae molt In biology, moulting (British English), or molting (American English), also known as sloughing, shed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Varied Carpet Beetle
The varied carpet beetle (''Anthrenus verbasci'') is a 3 mm-long beetle belonging to the family Dermestidae, positioned in subgenus Nathrenus. They are a common species, often considered a pest of domestic houses and, particularly, natural history museums, where the larvae may damage natural fibers and can damage carpets, furniture, clothing, and insect collections. ''A. verbasci'' was also the first insect to be shown to have an annual Chronobiology, behavioral rhythm and remains a classic example of Circannual Cycle, circannual cycles in animals. Description Adult ''A. verbasci'' range in length from . The body is rounded, almost spherical. The elytron, elytra and pronotum are covered in fine scales of different colours, creating an irregular pattern of white, brownish and yellowish patches on these features. The white scales are focussed along the lateral margins of the pronotum and on the elytra, where they form three bright, wavy transverse bands. In addition to these ...

Common Furniture Beetle
The common furniture beetle or common house borer (''Anobium punctatum'') is a woodboring beetle originally from Europe but now distributed worldwide. In the larval stage it bores in wood and feeds upon it. Adult ''Anobium punctatum'' measure in length. They have brown ellipsoidal bodies with a prothorax resembling a monk's cowl. The common furniture beetle is often confused with the drugstore beetle and cigarette beetle due to their similar appearance. The common furniture beetle can be distinguished from these other species by their lack of antennae as well as darker prothorax. Life cycle The female lays her eggs in cracks in wood or inside old exit holes, if available. The eggs hatch after some three weeks, each producing a long, creamy white, C-shaped larva. For three to four years the larvae bore semi-randomly through timber, following and eating the starchy part of the wood grain, and grow up to . They come nearer to the wood surface when ready to pupate. They excavat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
House Cricket
''Acheta domesticus'', commonly called the house cricket, is a species of cricket most likely native to Southwestern Asia, but between 1950 and 2000 it became the standard feeder insect for the pet and research industries and spread worldwide. They can be kept as pets themselves, as this has been the case in China and Japan. Description The house cricket is typically gray or brownish in color, growing to in length. Males and females look similar, but females will have a brown-black, needle-like ovipositor extending from the center rear, approximately the same length as the cerci, the paired appendages towards the rear-most segment of the cricket. On males, the cerci are more prominent. Diet The house cricket is an omnivore that eats a range of plant and animal matter. Crickets in the wild consume flowers, leaves, fruits, grasses and other insects (including dead members of their own species). Crickets in captivity will accept fruits (e.g. apples, oranges, bananas), veg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flour Mite
The flour mite, ''Acarus siro'', a pest of stored grains and animal feedstuffs, is one of many species of grain and flour mites. An older name for the species is ''Tyroglyphus farinae''. The flour mite, which is pale greyish white in colour with pink legs, is the most common species of mite in foodstuffs. The males are from long and the female is from long. The flour mites are found in grain and may become exceedingly abundant in poorly stored material. The female produces large clutches of eggs and the life cycle takes just over two weeks. The cast skins and dead bodies can form a fluffy brown material that accumulates under sacks on the warehouse floor. After a while, predatory mites tend to move in, and these keep the flour mites under control. Flour mites that contaminate grains, flour and animal feedstuffs, create allergens in the dust produced, and also transfer pathogenic microorganisms. Foodstuffs acquire a sickly sweet smell and an unpalatable taste. When fed infeste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drosophila Melanogaster - Side (aka)
''Drosophila'' (), from Ancient Greek δρόσος (''drósos''), meaning "dew", and φίλος (''phílos''), meaning "loving", is a genus of fly, belonging to the family Drosophilidae, whose members are often called "small fruit flies" or pomace flies, vinegar flies, or wine flies, a reference to the characteristic of many species to linger around overripe or rotting fruit. They should not be confused with the Tephritidae, a related family, which are also called fruit flies (sometimes referred to as "true fruit flies"); tephritids feed primarily on unripe or ripe fruit, with many species being regarded as destructive agricultural pests, especially the Mediterranean fruit fly. One species of ''Drosophila'' in particular, '' Drosophila melanogaster'', has been heavily used in research in genetics and is a common model organism in developmental biology. The terms "fruit fly" and "''Drosophila''" are often used synonymously with ''D. melanogaster'' in modern biological litera ...

Caterpillar
Caterpillars ( ) are the larval stage of members of the order Lepidoptera (the insect order comprising butterflies and moths). As with most common names, the application of the word is arbitrary, since the larvae of sawflies (suborder Symphyta) are commonly called caterpillars as well. Both lepidopteran and symphytan larvae have eruciform body shapes. Caterpillars of most species eat plant material ( often leaves), but not all; some (about 1%) eat insects, and some are even cannibalistic. Some feed on other animal products. For example, clothes moths feed on wool, and horn moths feed on the hooves and horns of dead ungulates. Caterpillars are typically voracious feeders and many of them are among the most serious of agricultural pests. In fact, many moth species are best known in their caterpillar stages because of the damage they cause to fruits and other agricultural produce, whereas the moths are obscure and do no direct harm. Conversely, various species of ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anatomical Terms Of Location
Standard anatomical terms of location are used to describe unambiguously the anatomy of humans and other animals. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and axes. The meaning of terms that are used can change depending on whether a vertebrate is a biped or a quadruped, due to the difference in the neuraxis, or if an invertebrate is a non-bilaterian. A non-bilaterian has no anterior or posterior surface for example but can still have a descriptor used such as proximal or distal in relation to a body part that is nearest to, or furthest from its middle. International organisations have determined vocabularies that are often used as standards for subdisciplines of anatomy. For example, '' Termi ...

Bird Food
Bird food or bird seed is food intended for consumption by wild, commercial, or pet birds. It is typically composed of seeds, nuts, dry fruits, flour, and may be enriched with vitamins and proteins. Bird food can vary depending upon dietary habits and beak shapes. Dietary habits refer to whether birds are naturally omnivores, carnivores, herbivores, insectivores or nectarivores. The shape of the beak, which correlates with dietary habits, is important in determining how a bird can crack the seed coat and obtain the meat of the seed. Black-oil sunflower seeds attract the widest variety of birds and are commonly used in backyard bird feeders. Using a variety of seeds can help attract specific types of birds to gardens and backyards. In general, mixtures predominantly containing red millet, oats, and other "fillers" are not attractive to most birds. These mixtures can lead to waste as the birds sort through the mix, and can potentially result in fungal and bacterial growth. W ...

Grain
A grain is a small, hard, dry fruit (caryopsis) – with or without an attached husk, hull layer – harvested for human or animal consumption. A grain crop is a grain-producing plant. The two main types of commercial grain crops are cereals and legumes. After being harvested, dry grains are more durable than other staple foods, such as starchy fruits (plantain (cooking), plantains, breadfruit, etc.) and tubers (sweet potatoes, cassava, and more). This durability has made grains well suited to industrial agriculture, since they can be mechanically harvested, transported by rail or ship, stored for long periods in silos, and mill (grinding), milled for flour or expeller pressing, pressed for Seed oil, oil. Thus, the grain market is a major global commodity market that includes crops such as maize, rice, soybeans, wheat and other grains. Cereal and non-cereal grains In the grass family, a grain (narrowly defined) is a caryopsis, a fruit with its wall fused on to the single seed ...
