Suidasia Australiensis
''Suidasia'' is a genus of mites in the family Suidasiidae and clade Astigmatina. Description The body of ''Suidasia'' mites has various patterns. If small rounded protuberances are present, these are coalescent and at least some are unequal. The dorsal surface is covered in smooth setae. The prodorsum has external vertical setae ''ve'' on the sides of the prodorsal sclerite and near the transverse level of setae ''vi''. The supracoxal setae are lanceolate in shape and have fimbriate margins. The hysterosomal setae are short and do not reach the bases of next setae. On the ventral surface of the body, the anus is positioned near the pretarsal margin. The ventral subcapitulum is without external ridges. Each leg ends in pretarsi ambulacra that are not greatly expanded, and in empodial claws that are simple. The tarsi have solenidion ''ω2'' and setae ''e'' and ''f'', the latter two both being filiform. Ecology ''Suidasia'' are generalists found in various habitats, such as ...

Generalist And Specialist Species
A generalist species is able to thrive in a wide variety of environmental conditions and can make use of a variety of different resources (for example, a heterotroph with a varied diet). A specialist species can thrive only in a narrow range of environmental conditions or has a limited diet. Most organisms do not all fit neatly into either group, however. Some species are highly specialized (the most extreme case being monophagous, eating one specific type of food), others less so, and some can tolerate many different environments. In other words, there is a continuum from highly specialized to broadly generalist species. Description Omnivores are usually generalists. Herbivores are often specialists, but those that eat a variety of plants may be considered generalists. A well-known example of a specialist animal is the monophagous koala, which subsists almost entirely on eucalyptus leaves. The raccoon is a generalist, because it has a natural range that includes most of North ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mite
Mites are small arachnids (eight-legged arthropods). Mites span two large orders of arachnids, the Acariformes and the Parasitiformes, which were historically grouped together in the subclass Acari, but genetic analysis does not show clear evidence of a close relationship. Most mites are tiny, less than in length, and have a simple, unsegmented body plan. The small size of most species makes them easily overlooked; some species live in water, many live in soil as decomposers, others live on plants, sometimes creating galls, while others again are Predation, predators or Parasitism, parasites. This last type includes the commercially destructive ''Varroa'' parasite of honey bees, as well as scabies mites of humans. Most species are harmless to humans, but a few are associated with allergies or may transmit diseases. The scientific discipline devoted to the study of mites is called acarology. Evolution and taxonomy The mites are not a defined taxon, but is used for two disti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allergy
Allergies, also known as allergic diseases, refer a number of conditions caused by the hypersensitivity of the immune system to typically harmless substances in the environment. These diseases include hay fever, food allergies, atopic dermatitis, allergic asthma, and anaphylaxis. Symptoms may include red eyes, an itchy rash, sneezing, coughing, a runny nose, shortness of breath, or swelling. Note: food intolerances and food poisoning are separate conditions. Common allergens include pollen and certain foods. Metals and other substances may also cause such problems. Food, insect stings, and medications are common causes of severe reactions. Their development is due to both genetic and environmental factors. The underlying mechanism involves immunoglobulin E antibodies (IgE), part of the body's immune system, binding to an allergen and then to a receptor on mast cells or basophils where it triggers the release of inflammatory chemicals such as histamine. Diagnosis is ty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oral Mite Anaphylaxis
Oral mite anaphylaxis (OMA), also known as pancake syndrome, is a disease in which a person gets symptoms after eating food contaminated with particular mites. The disease name comes from reports of people becoming ill after eating pancakes made from contaminated wheat or corn (maize) flour. Symptoms and signs The symptoms are allergic symptoms, especially trouble breathing, swelling of the face and throat, runny nose, cough, difficulty swallowing, and wheals. Anaphylaxis can occur during exposure to NSAID drugs or exercise in people exposed to the mites. Cause Dust mites are microscopic arachnids that produce very powerful allergens. If dust mites get into the food, then anyone eating the food is eating the allergens and may have an allergic reaction against them. The specific mites suspected as causing the condition are ''Dermatophagoides pteronyssinus'', ''Blomia tropicalis Blomia may refer to: * '' Blomia (mite)'', a genus of mites in the family Echimyopodidae * '' Blomia ...

Trogidae
Trogidae, sometimes called hide beetles, is a family of beetles with a distinctive warty or bumpy appearance. Found worldwide, the family includes about 300 species contained in four or five genera. Trogids range in length from 2 to 20 mm. Their shape is oblong to oval, with a generally flat abdomen. Their color ranges from brown to gray or black, and they often encrust their bodies with soil. They resemble scarab beetles with heavy limbs and spurs. They are scavengers and are among the last species to visit and feed on carrion. They are most often found on the dry remains of dead animals. Both adults and larvae eat feathers and skin. Some species are found in bird and mammal nests. Details of the life histories of many species are poorly known, since many are specialized to particular types of nests. They are often overlooked by predators and collectors due to their behaviors of covering their bodies with soil and becoming motionless when disturbed. This group may also be con ...

Trox
''Trox'' is a genus of hide beetle in the subfamily Troginae. Taxonomy In recent years, scientists have revamped the taxonomy of ''Trox''. The formerly massive genus, which boasted a whopping 160 species, has been cut down. Specifically, the subgenera '' Phoberus'' and '' Glyptotrox'' have been reelevated as their own separate genera, while various ''Trox'' species have been merged or otherwise combined. After taxonomic revisions, the genus ''Trox'' contains three subgenera - '' Trox (Trox)'', '' Trox (Niditrox)'', and '' Trox (Granulitrox)'' -, with the following species: Subgenus ''Trox'' *'' Trox acanthinus'' Harold, 1872 *'' Trox antiquus'' Wickham, 1909 *'' Trox cadaverinus'' Illiger, 1802 *'' Trox capillaris'' Say, 1824 *'' Trox contractus'' Robinson, 1940 *'' Trox coracinus'' Gmelin, 1788 *'' Trox cretaceus'' Nikolajev, 2007 *'' Trox floridanus'' Howden & Vaurie, 1957 *'' Trox gansuensis'' Ren, 2003 *'' Trox gemmulatus'' Horn, 1874 *'' Trox horiguchii'' Ochi & Kawahara ...

Phoresis
Phoresis or phoresy is a non-permanent, commensalistic interaction in which one organism (a phoront or phoretic) attaches itself to another (the host) solely for the purpose of travel. Phoresis has been observed directly in ticks and mites since the 18th century, and indirectly in fossils 320 million years old. It is not restricted to arthropods or animals; plants with seeds that disperse by attaching themselves to animals are also considered to be phoretic. ''Phoresis'' is rooted in the Greek words ''phoras'' (bearing) and ''phor'' (thief). The term, originally defined in 1896 as a relationship in which the host acts as a vehicle for its passenger, clashed with other terminology being developed at the time, so constraints on the length of time, feeding and ontogeny are now considered. Phoresis is used as a strategy for dispersal, seasonal migration, transport to new host/habitat escaping ephemeral habitats, and reducing inbreeding depression. In addition to the bene ...

Subcapitulum
The subcapitulum (from Latin ''sub'', "under", and ''capitulum'', "small head"), also known as infracapitulum, hypognathum or hipognatum, refers to the ventral part of the gnathosoma (the part of the body comprising the mouth and feeding parts) or the fusion of the palpal (of the pedipalps, the second pair of appendages) coxae (the point of union of the appendages with the body) and the labrum (the upper mouthpart) complex present in some arthropods on which the mouth, pedipalps, mouthparts and pharynx are generally located. It is delimited by the subcapitular apodeme (an ingrowth of the exoskeleton for muscle attachment), which separates it from the cheliceral (of the chelicerae, the first pair of appendages) frame. Acari The function or morphology of the subcapitulum can vary within acarines. In its central part, the hypostomal (of the hypostome, a harpoon-like appendage near the mouth) gutter in which the pincers are transformed into a serrated pricking system is formed. The ...

Sclerite
A sclerite (Greek , ', meaning "hard") is a hardened body part. In various branches of biology the term is applied to various structures, but not as a rule to vertebrate anatomical features such as bones and teeth. Instead it refers most commonly to the hardened parts of arthropod exoskeletons and the internal spicules of invertebrates such as certain sponges and soft corals. In paleontology, a scleritome is the complete set of sclerites of an organism, often all that is known from fossil invertebrates. Sclerites in combination Sclerites may occur practically isolated in an organism, such as the sting of a cone shell. Also, they can be more or less scattered, such as tufts of defensive sharp, mineralised bristles as in many marine Polychaetes. Or, they can occur as structured, but unconnected or loosely connected arrays, such as the mineral "teeth" in the radula of many Mollusca, the valves of Chitons, the beak of Cephalopod, or the articulated exoskeletons of Arthropoda.
