Ormia Depleta
''Ormia depleta'', sometimes called the Brazilian red-eyed fly, is a species of fly in the family Tachinidae. It is a parasitoid of mole crickets in the genus ''Scapteriscus''. It is native to South America but has been imported into the United States and elsewhere as a biological pest control agent. Biology ''Ormia depleta'' has four stages in its life cycle, egg, larva, pupa and adult. The adult female is attracted by the song of either the tawny mole cricket (''Neoscapteriscus vicinus'') or the southern mole cricket (''Neoscapteriscus borellii''). The repeated chirps are emitted by the male crickets to attract females to breed, and the song also lures the female fly. Her eggs hatch inside her abdomen and she deposits a larva on any mole cricket with which she comes in contact. The fly larva feeds on the mole cricket and eventually kills it, then the fly larva emerges from the carcass and makes its way into the soil where it pupates. The adult fly emerges from the pupa about ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Honeydew (secretion)
Honeydew is a sugar-rich sticky liquid, secreted by aphids and some scale insects as they feed on plant sap. When their mouthpart penetrates the phloem, the sugary, high-pressure liquid is forced out of the anus of the aphid. Honeydew is particularly common as a secretion in hemipteran insects and is often the basis for trophobiosis. Some caterpillars of Lycaenidae butterflies and some moths also produce honeydew. Honeydew producing insects, like cicadas, pierce phloem ducts to access the sugar rich sap. The sap continues to bleed after the insects have moved on, leaving a white sugar crust called manna. Ants may collect, or "milk", honeydew directly from aphids and other honeydew producers, which benefit from their presence due to their driving away predators such as lady beetles or parasitic wasps—see ''Crematogaster peringueyi''. Animals and plants in a mutually symbiotic arrangement with ants are called Myrmecophiles. In Madagascar, some gecko species in the genera ''Ph ...

Sepsis
Sepsis, formerly known as septicemia (septicaemia in British English) or blood poisoning, is a life-threatening condition that arises when the body's response to infection causes injury to its own tissues and organs. This initial stage is followed by suppression of the immune system. Common signs and symptoms include fever, tachycardia, increased heart rate, hyperventilation, increased breathing rate, and mental confusion, confusion. There may also be symptoms related to a specific infection, such as a cough with pneumonia, or dysuria, painful urination with a pyelonephritis, kidney infection. The very young, old, and people with a immunodeficiency, weakened immune system may have no symptoms of a specific infection, and the hypothermia, body temperature may be low or normal instead of having a fever. Severe sepsis causes organ dysfunction, poor organ function or blood flow. The presence of Hypotension, low blood pressure, high blood Lactic acid, lactate, or Oliguria, low urine o ...

Bacteria
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria are vital in many stages of the nutrient cycle by recycling nutrients such as the fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulphide and methane, to energy. Bacteria also live in symbiotic and parasitic relationsh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nematode
The nematodes ( or grc-gre, Νηματώδη; la, Nematoda) or roundworms constitute the phylum Nematoda (also called Nemathelminthes), with plant-Parasitism, parasitic nematodes also known as eelworms. They are a diverse animal phylum inhabiting a broad range of environments. Less formally, they are categorized as Helminths, but are taxonomically classified along with Arthropod, arthropods, Tardigrade, tardigrades and other moulting animalia, animals in the clade Ecdysozoa, and unlike platyhelminthe, flatworms, have tubular digestion, digestive systems with openings at both ends. Like tardigrades, they have a reduced number of Hox genes, but their sister phylum Nematomorpha has kept the ancestral protostome Hox genotype, which shows that the reduction has occurred within the nematode phylum. Nematode species can be difficult to distinguish from one another. Consequently, estimates of the number of nematode species described to date vary by author and may change rapidly over ...

Steinernema Scapterisci
''Steinernema scapterisci'', the mole cricket nematode, is a species of nematode in the order Rhabditida. It is a parasite of insects in the order Orthoptera, the grasshoppers, crickets and their allies. Native to southern South America, it was introduced into Florida in the United States in an effort to provide a biological control of pest (''Neoscapteriscus'') mole crickets. A second species of "mole cricket nematode" exists in Florida, and probably elsewhere in the eastern USA. It is now called ''Steinernema neocurtillae'' Nguyen, Smart, and is known to attack only the native mole cricket ''Neocurtilla hexadactyla'' Description ''Steinernema scapterisci'' can be distinguished from other species of its genus "by the presence of prominent cheilorhabdions, an elliptically shaped structure associated with the excretory duct, and a double-flapped epitygma in the first-generation female." It does not hybridise with '' Steinernema carpocapsae'', and it infects and kills fewer than 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Larra Bicolor
''Larra bicolor'' is a parasitoid wasp native to South America. It was introduced into Florida as a biological pest control of invasive mole crickets. Description Adult females of this species are about 22 mm long, with the males somewhat smaller. The head and thorax are black, with silver markings on the head; the abdomen is red. The wings are variable in color, of a dusky hue. Life cycle These wasps feed on nectar as adults, with the shrubby false buttonweed (''Spermacoce verticillata'') preferred. Females hunt mole crickets in the genus ''Scapteriscus'', stinging them on the underside to paralyze them for several minutes. A single egg is deposited between the first and second pairs of legs. The wasp then flies off, and the cricket returns to its burrow. Nymphs and adult crickets are attacked, as long as they are large enough. Upon hatching, the larva feeds upon its host, eventually killing it. It pupates within 12 to 30 days (depending on temperature), forming a cocoo ...

Scapteriscus Borellii
''Scapteriscus borellii'', the southern mole cricket, is a species of insect in the family Gryllotalpidae. It is native to South America but is also present in the southern United States where it was introduced around 1900. Description ''Scapteriscus borellii'' is a fairly large mole cricket growing to a length of about . Like other members of this genus, it is characterized by having two sharp claws and a blade-like process with a sharp edge on its forelegs. Other mole crickets have three or four claws.Rodríguez, F.; Heads, S. (2012)New mole crickets of the genus ''Scapteriscus'' Scudder from Colombia (Orthoptera: Gryllotalpidae; Scapteriscinae).''Zootaxa'' 3282, 61–68. The two claws are separated at the base by a gap half the width of the claw, which distinguishes this species from the tawny mole cricket (''S. vicinus'') which has claws that nearly touch at the base. The tegmina (forewings) are longer than the prothorax and the membranous hind wings are longer than the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tachinidae
The Tachinidae are a large and variable family of true flies within the insect order Diptera, with more than 8,200 known species and many more to be discovered. Over 1,300 species have been described in North America alone. Insects in this family commonly are called tachinid flies or simply tachinids. As far as is known, they all are protelean parasitoids, or occasionally parasites, of arthropods, usually other insects. The family is known from many habitats in all zoogeographical regions and is especially diverse in South America. Life cycle Reproductive strategies vary greatly between Tachinid species, largely, but not always clearly, according to their respective life cycles. This means that they tend to be generalists rather than specialists. Comparatively few are restricted to a single host species, so there is little tendency towards the close co-evolution one finds in the adaptations of many specialist species to their hosts, such as are typical of protelean parasito ...

Neoscapteriscus Vicinus
''Neoscapteriscus vicinus'', the tawny mole cricket, is a species of insect in the mole cricket family, Gryllotalpidae. This species is native to South America and also occurs in the Southern United States, where it arrived as a contaminant of ship's ballast around 1900. Colombian insect taxonomist Oscar Cadena-Castañeda studied specimens of the genus which had been called ''Scapteriscus'', and decided that it included two groups; a smaller group (the true ''Scapteriscus'') and a larger group that he named ''Neoscapteriscus'' (a new genus) in 2015. North American mole cricket taxonomists agreed with his decision and altered Orthoptera Species File Online accordingly. Description ''N. vicinus'' is a medium-sized mole cricket. Members of this genus are characterized by having two sharp claws and a blade-like process with a sharp edge on their fore legs. Other mole crickets have three or four claws. Its colour is yellowish-brown with a dark prothorax. It can be differentiated from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 holometabolous: they go through four distinct stages in their life cycle, the stages thereof being egg, larva, pupa, and imago. The processes of entering and completing the pupal stage are controlled by the insect's hormones, especially juvenile hormone, prothoracicotropic hormone, and ecdysone. The act of becoming a pupa is called pupation, and the act of emerging from the pupal case is called eclosion or emergence. The pupae of different groups of insects have different names such as ''chrysalis'' for the pupae of butterflies and ''tumbler'' for those of the mosquito family. Pupae may further be enclosed in other structures such as cocoons, nests, or shells. Position in life cycle The pupal stage follows the larval stage and precedes adulthood (''imago'') in insects with complete metamorphosi ...
