Leaffooted
Coreidae is a large family of predominantly sap-sucking insects in the Hemipteran suborder Heteroptera. The name "Coreidae" derives from the genus ''Coreus'', which derives from the Ancient Greek () meaning bedbug. As a family, the Coreidae are cosmopolitan, but most of the species are tropical or subtropical. Common names and significance The common names of the Coreidae vary regionally. Leaf-footed bug refers to leaf-like expansions on the legs of some species, generally on the hind tibiae. In North America, the pest status of species such as ''Anasa tristis'' on squash plants and other cucurbits gave rise to the name squash bugs. The Coreidae are called twig-wilters or tip-wilters in parts of Africa and Australia because many species feed on young twigs, injecting enzymes that macerate the tissues of the growing tips and cause them to wilt abruptly. Morphology and appearance The Coreidae commonly are oval-shaped, with antennae composed of four segments, numerous veins in ...

Anoplocnemis Curvipes
''Anoplocnemis curvipes'' is a species of sap-sucking insect in the genus ''Anoplocnemis''. They are native to Sub-Saharan Africa, sub-saharan Africa where they are considered a major pest of many types of agricultural plants such as trees and shrubs, including legumes. This has earned them the name leaf-wilter. References Mictini {{coreidae-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Squash (plant)
''Cucurbita'' (Latin for gourd) is a genus of herbaceous fruits in the gourd family, Cucurbitaceae (also known as ''cucurbits'' or ''cucurbi''), native to the Andes and Mesoamerica. Five edible species are grown and consumed for their flesh and seeds. They are variously known as squash, pumpkin, or gourd, depending on species, variety, and local parlance. Other kinds of gourd, also called bottle-gourds, are native to Africa and belong to the genus ''Lagenaria'', which is in the same family and subfamily as ''Cucurbita'', but in a different tribe. These other gourds are used as utensils or vessels, and their young fruits are eaten much like those of the ''Cucurbita'' species. Most ''Cucurbita'' species are herbaceous vines that grow several meters in length and have tendrils, but non-vining "bush" cultivars of ''C. pepo'' and ''C. maxima'' have also been developed. The yellow or orange flowers on a ''Cucurbita'' plant are of two types: female and male. The female flowe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metathorax
The metathorax is the posterior of the three segments in the thorax of an insect, and bears the third pair of legs. Its principal sclerites ( exoskeletal plates) are the metanotum (dorsal), the metasternum (ventral), and the metapleuron (lateral) on each side. The metathorax is the segment that bears the hindwings in most winged insects, though sometimes these may be reduced or modified, as in the flies (Diptera), in which they are reduced to form halteres, or flightless, as in beetles (Coleoptera), in which they may be completely absent even though forewings are still present. All adult insects possess legs on the metathorax. In most groups of insects, the metanotum is reduced relative to the mesonotum. In the suborder Apocrita of the Hymenoptera, the first abdominal segment is fused to the metathorax, and is then called the propodeum.

Ecdysis
Ecdysis is the moulting of the cuticle in many invertebrates of the clade Ecdysozoa. Since the cuticle of these animals typically forms a largely inelastic exoskeleton, it is shed during growth and a new, larger covering is formed. The remnants of the old, empty exoskeleton are called exuviae. After moulting, an arthropod is described as ''teneral'', a ''callow''; it is "fresh", pale and soft-bodied. Within one or two hours, the cuticle hardens and darkens following a tanning process analogous to the production of leather. During this short phase the animal expands, since growth is otherwise constrained by the rigidity of the exoskeleton. Growth of the limbs and other parts normally covered by the hard exoskeleton is achieved by transfer of body fluids from soft parts before the new skin hardens. A spider with a small abdomen may be undernourished but more probably has recently undergone ecdysis. Some arthropods, especially large insects with tracheal respiration, expand thei ...

Tergum
A ''tergum'' (Latin for "the back"; plural ''terga'', associated adjective tergal) is the Anatomical terms of location#Dorsal and ventral, dorsal ('upper') portion of an arthropod segment other than the head. The Anatomical terms of location#Anterior and posterior, anterior edge is called the 'base' and posterior edge is called the 'apex' or 'margin'. A given tergum may be divided into hardened plates or sclerites commonly referred to as tergites. In a Thorax (insect anatomy), thoracic segment, for example, the tergum may be divided into an anterior notum and a posterior Scutellum (insect), scutellum. Lateral extensions of a tergite are known as paranota (Greek for "alongside the back") or ''carinae'' (Latin for "keel"), exemplified by the flat-backed millipedes of the order Polydesmida. Kinorhynchs have tergal and sternal plates too, though seemingly not homologous with those of arthropods. Tergo-tergal is a stridulation, stridulatory mechanism in which fine spines of the abdom ...

Median Plane
The median plane also called a mid-sagittal plane is used to describe the sagittal plane as it bisects the body vertically through the midline marked by the navel, dividing the body exactly in left and right side. The term parasagittal plane is used to refer to any plane parallel to the sagittal and median plane. It is one of the lines used to define the right upper quadrant of the human abdomen. The midsternal line can be interpreted as a segment of the median plane. File:Sagittal brain MRI.jpg, Median plane magnetic resonance imaging of the head.

Nymph (biology)
In biology, a nymph is the immature form of some invertebrates, particularly insects, which undergoes gradual metamorphosis (hemimetabolism) before reaching its adult stage. Unlike a typical larva, a nymph's overall form already resembles that of the adult, except for a lack of wings (in winged species). In addition, while a nymph moults, it never enters a pupal stage. Instead, the final moult results in an adult insect. Nymphs undergo multiple stages of development called instars. This is the case, for example, in Orthoptera (crickets, grasshoppers and locusts), Hemiptera (cicadas, shield bugs, whiteflies, aphids, leafhoppers, froghoppers, treehoppers etc.), mayflies, termites, cockroaches, mantises, stoneflies and Odonata (dragonflies and damselflies). Nymphs of aquatic insects, as in the Odonata, Ephemeroptera, and Plecoptera, are also called naiads, an Ancient Greek name for mythological water nymphs. Usage of the term 'naiad' is no longer popular among entomologists, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, plural ''coxae''), ''trochanter'', ''femur'' (plural ''femora''), ''tibia'' (plural ''tibiae''), ''tarsus'' (plural ''tarsi''), ''ischium'' (plural ''ischia''), ''metatarsus'', ''carpus'', ''dactylus'' (meaning finger), ''patella'' (plural ''patellae''). 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 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 ''Hox''-gene, could result in parallel gains of leg segments. In arthropods, each of the leg segments ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robustness
Robustness is the property of being strong and healthy in constitution. When it is transposed into a system, it refers to the ability of tolerating perturbations that might affect the system’s functional body. In the same line ''robustness'' can be defined as "the ability of a system to resist change without adapting its initial stable configuration". "Robustness in the small" refers to situations wherein perturbations are small in magnitude, which considers that the "small" magnitude hypothesis can be difficult to verify because "small" or "large" depends on the specific problem. Conversely, "Robustness in the large problem" refers to situations wherein no assumptions can be made about the magnitude of perturbations, which can either be small or large.C.Alippi: "Robustness Analysis" chapter in ''Intelligence for Embedded Systems.'' Springer, 2014, 283pp, . It has been discussed that robustness has two dimensions: resistance and avoidance.Durach, C.F. et al. (2015)Antecedents an ...

Laciniate
The following is a list of terms which are used to describe leaf plant morphology, morphology in the description and taxonomy (biology), taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflet (botany), leaflets). The edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf#Terminology, leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aberrant
''Aberrant'' is a role-playing game created by White Wolf Game Studio in 1999, set in 2008 in a world where super-powered humans started appearing one day in 1998. It is the middle setting in the greater Trinity Universe timeline, chronologically situated about 90 years after '' Adventure!'', White Wolf's Pulp era game, and over a century before the psionic escapades of '' Trinity/Aeon''. The game deals with how the players' meta-human characters (called "novas") fit into a mundane world when they most definitely are ''not'' mundane, as well as how the mundane populace react to the sudden emergence of novas. The original ''Aberrant'' product line was discontinued in 2002, though a d20 System version was released in 2004. Onyx Path Publishing has recently acquired the rights to the Trinity Universe and released a new edition of the game, titled ''Trinity Continuum: Aberrant'', in 2021. Setting ''Aberrant'' is the middle game of the Trinity Universe, and is thus the prequel t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
