Miridae Genera
The Miridae are a large and diverse insect family at one time known by the taxonomic synonym Capsidae. Species in the family may be referred to as capsid bugs or "mirid bugs". Common names include plant bugs, leaf bugs, and grass bugs. It is the largest family of true bugs (suborder Heteroptera); it includes over 10,000 known species, and new ones are being described constantly. Most widely known mirids are species that are notorious agricultural pests that pierce plant tissues, feed on the sap, and sometimes transmit viral plant diseases. Some species however, are predatory. Description Miridae are small, terrestrial insects, usually oval-shaped or elongate and measuring less than in length. Many of them have a hunched look, because of the shape of the prothorax, which carries the head bent down. Some are brightly coloured and attractively patterned, others drab or dark, most being inconspicuous. Some genera are ant mimics at certain stages of life. Miridae do not have any oc ...

Rhabdomiris Striatellus
''Rhabdomiris striatellus'' is a Hemiptera, bug found widespread through the Europe with the exception of the extreme north and the southern Mediterranean basin, Mediterranean. Its range extends east across Asia Minor to the Caucasus. It is common in the British Isles. The species is associated with oak trees. The body of the insect reaches . The body is yellow to reddish brown and has yellow veins and dark stripes on its wings. The bug can also be much darker and similar to its relative, ''Miris striatus''. The Nymph (biology), nymphs suck flowers and fruits while the adults prey on aphids and the larvae of other insects.

Mimic
In evolutionary biology, mimicry is an evolved resemblance between an organism and another object, often an organism of another species. Mimicry may evolve between different species, or between individuals of the same species. In the simplest case, as in Batesian mimicry, a mimic resembles a model, so as to deceive a dupe, all three being of different species. A Batesian mimic, such as a hoverfly, is harmless, while its model, such as a wasp, is harmful, and is avoided by the dupe, such as an insect-eating bird. Birds hunt by sight, so the mimicry in that case is visual, but in other cases mimicry may make use of any of the senses. Most types of mimicry, including Batesian, are deceptive, as the mimics are not harmful, but Müllerian mimicry, where different harmful species resemble each other, is honest, as when species of wasps and of bees all have genuinely aposematic warning coloration. More complex types may be bipolar, involving only two species, such as when the mod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stenotus Binotatus
''Stenotus binotatus'' is a species of plant bug, originally from Europe, but now also established across North America and New Zealand. It is long, yellowish, with darker markings on the pronotum and forewings. It feeds on various grasses, and can be a pest of crops such as wheat. Description ''Stenotus binotatus'' is a fairly large plant bug ( long), which is somewhat variable in appearance. The insect's sides are roughly parallel, and the colours depend on both the animal's sex and its age, the markings becoming darker and stronger with increasing age. Males are mostly yellow, with darker markings on the pronotum and forewings, which females are greenish-yellow with paler markings. Distribution ''S. binotatus'' is native to most of the Palearctic but has been introduced to temperate regions around the world. It is common "throughout the northern and central U.S. and southern Canada", and it has been introduced to New Zealand, where it is now found almost throughout the coun ...

Alfalfa
Alfalfa () (''Medicago sativa''), also called lucerne, is a perennial plant, perennial flowering plant in the legume family Fabaceae. It is cultivated as an important forage crop in many countries around the world. It is used for grazing, hay, and silage, as well as a green manure and cover crop. The name alfalfa is used in North America. The name lucerne is more commonly used in the United Kingdom, South Africa, Australia, and New Zealand. The plant superficially resembles clover (a cousin in the same family), especially while young, when glossary of leaf morphology#trifoliate, trifoliate leaves comprising round leaflet (botany), leaflets predominate. Later in maturity, leaflets are elongated. It has raceme, clusters of small purple flowers followed by fruits spiralled in two to three turns containing 10–20 seeds. Alfalfa is native to warmer temperate climates. It has been cultivated as livestock fodder since at least the era of the Ancient Greece, ancient Greeks and Ancient R ...

Strawberry
The garden strawberry (or simply strawberry; ''Fragaria × ananassa'') is a widely grown Hybrid (biology), hybrid plant cultivated worldwide for its fruit. The genus ''Fragaria'', the strawberries, is in the rose family, Rosaceae. The fruit is appreciated for its aroma, bright red colour, juicy texture, and sweetness. It is eaten either fresh or in prepared foods such as fruit preserves, jam, ice cream, and chocolates. Artificial strawberry flavourings and aromas are widely used in commercial products. Botanically, the strawberry is not a berry (botany), berry, but an aggregate fruit, aggregate accessory fruit, accessory fruit. Each apparent 'seed' on the outside of the strawberry is actually an achene, a botanical fruit with a seed inside it. The garden strawberry was first bred in Brittany, France, in the 1750s via a cross of ''Virginia strawberry, F. virginiana'' from eastern North America and ''Fragaria chiloensis, F. chiloensis'', which was brought from Chile by Amédé ...

Cotton Plant
''Gossypium'' () is a genus of flowering plants in the tribe Gossypieae of the mallow family, Malvaceae, from which cotton is harvested. It is native to tropical and subtropical regions of the Old and New Worlds. There are about 50 ''Gossypium'' species, making it the largest genus in the tribe Gossypieae, and new species continue to be discovered. The name of the genus is derived from the Arabic word ''goz'', which refers to a soft substance. Cotton is the primary natural fibre used by humans today, amounting to about 80% of world natural fibre production. Where cotton is cultivated, it is a major oilseed crop and a main protein source for animal feed. Cotton is thus of great importance for agriculture, industry and trade, especially for tropical and subtropical countries in Africa, South America and Asia. Consequently, the genus ''Gossypium'' has long attracted the attention of scientists. The origin of the genus ''Gossypium'' is dated to around 5–10 million years ...

Lygus
The genus ''Lygus'' includes over 40 species of plant-feeding insects in the family Miridae. The term lygus bug is used for any member of genus ''Lygus''. Species At one time, nearly 200 species were classified as genus ''Lygus'', but most of those have since been reclassified into new or existing genera. Species within this genus include: * '' Lygus abroniae'' * '' Lygus aeratus'' * '' Lygus atriflavus'' * '' Lygus atritibialis'' * '' Lygus borealis'' * '' Lygus bradleyi'' * '' Lygus ceanothi'' * '' Lygus convexicollis'' * '' Lygus elisus'' * '' Lygus gemellatus'' * '' Lygus hesperus'' * '' Lygus humeralis'' * '' Lygus keltoni'' * ''Lygus lineolaris'' * '' Lygus lupini'' * ''Lygus maritimus'' * '' Lygus mexicanus'' * '' Lygus oregonae'' * ''Lygus perplexus'' * ''Lygus plagiatus'' * ''Lygus potentillae'' * ''Lygus pratensis'' * ''Lygus punctatus'' * ''Lygus robustus'' * ''Lygus rolfsi'' * ''Lygus rubroclarus'' * ''Lygus rubrosignatus'' * ''Lygus rufidorsus'' * ''Lygus rugulipenni ...

Arthropod Leg
The arthropod leg is a form of jointed appendage of arthropods, usually used for walking. Many of the terms used for arthropod leg segments (called podomeres) are of Latin origin, and may be confused with terms for bones: ''coxa'' (meaning hip (anatomy), hip, : ''coxae''), ''trochanter'', ''femur'' (: ''femora''), ''tibia'' (: ''tibiae''), ''tarsus'' (: ''tarsi''), ''ischium'' (: ''ischia''), ''metatarsus'', ''carpus'', ''dactylus'' (meaning finger), ''patella'' (: ''patellae''). Homology (biology), Homologies of leg segments between groups are difficult to prove and are the source of much argument. Some authors posit up to eleven segments per leg for the most recent common ancestor of Neontology, extant arthropods but modern arthropods have eight or fewer. It has been argued that the ancestral leg need not have been so complex, and that other events, such as successive loss of function of a Homeobox, ''Hox''-gene, could result in Parallel evolution, parallel gains of leg segments ...

Anthocoridae
Anthocoridae is a family of bugs, commonly called minute pirate bugs or flower bugs. Worldwide there are 500-600 species. Description Anthocoridae are 1.5–5 mm long and have soft, elongated oval, flat bodies, often patterned in black and white. The head is extended forward and the antennae are longer than the head and visible from above. They possess a piercing and sucking three-segmented beak or labium used to inject prey with digestive enzymes and consume food. In general appearance, they resemble common plant bugs (Miridae), but Anthocoridae differ by their possession of two ocelli as adults. Anthocorids possess two pairs of wings with hemelytra and membranous hindwings. Many species are referred to as insidious flower bugs or pirate bugs. The scientific name is a combination of the Greek words ''anthos'' "flower" and ''koris'' "bug". Habitat and behaviour Many species can be found in cryptic habitats such as galls, but can also be present in open surface environm ...

Hemiptera
Hemiptera (; ) is an order of insects, commonly called true bugs, comprising more than 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, assassin bugs, bed bugs, and shield bugs. They range in size from to around , and share a common arrangement of piercing-sucking mouthparts. The name "true bugs" is sometimes limited to the suborder Heteroptera. Entomologists reserve the term ''bug'' for Hemiptera or Heteroptera,Gilbert Waldbauer. ''The Handy Bug Answer Book.'' Visible Ink, 1998p. 1. which does not include other arthropods or insects of other orders such as ants, bees, beetles, or butterflies. In some varieties of English, all terrestrial arthropods (including non-insect arachnids and myriapods) also fall under the colloquial understanding of ''bug''. Many insects with "bug" in their common name, especially in American English, belong to other orders; for example, the lovebug is a fly and the Maybug and ladybug are beetles. ...

Elytron
An elytron (; ; : elytra, ) is a modified, hardened forewing of beetles (Coleoptera), though a few of the true bugs (Hemiptera) such as the family Schizopteridae are extremely similar; in true bugs, the forewings are called hemelytra (sometimes alternatively spelled as "hemielytra"), and in most species only the basal half is thickened while the apex is membranous, but when they are entirely thickened the condition is referred to as "coleopteroid". An elytron is sometimes also referred to as a shard. Description The elytra primarily serve as protective wing-cases for the hindwings underneath, which are used for flying. To fly, a beetle typically opens the elytra and then extends the hindwings, flying while still holding the elytra open, though many beetles in the families Scarabaeidae and Buprestidae can fly with the elytra closed (e.g., most Cetoniinae; ). In a number of groups, the elytra are reduced to various degrees, (e.g., the beetle families Staphylinidae and Ripiphorid ...

Sclerotin
Sclerotin is a component of the cuticle of various Arthropoda, most familiarly insects. It is formed by cross-linking members of particular classes of protein molecules, a biochemical process called sclerotization, a form of tanning in which quinones are enzymatically introduced into the cuticle, and react with terminal and lysine-related amino groups in the proteins to form strong links between the molecules.Chapman, R.F. (1969) ''The Insects: Structure and Function''. Elsevier, New York. Chapter 22.37 - "Expansion of the new cuticle is brought to an end by the onset of tanning" The resulting material greatly increases the rigidity of an insect's chitinous exoskeleton, which is otherwise fairly soft. It is particularly prominent in the thicker, armoured parts of insect and arachnid Arachnids are arthropods in the Class (biology), class Arachnida () of the subphylum Chelicerata. Arachnida includes, among others, spiders, scorpions, ticks, mites, pseudoscorpions, opiliones, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
