Kneallhazia Solenopsae
''Kneallhazia solenopsae'' is a unique pathogenic intracellular microsporidium, that infects two of the fire ant species: the red ''Solenopsis invicta The red imported fire ant (''Solenopsis invicta''), also known as the fire ant or RIFA, is a species of ant native to South America. A member of the genus '' Solenopsis'' in the subfamily Myrmicinae, it was described by Swiss entomologist Fel ...'' and the black '' Solenopsis richteri'' in North and South America. ''Kneallhazia solenopsae'' was originally named ''Thelohania solenopsae''. In the 1970s Knell, Allen and Hazard described some marked differences. Further field studies in the mid 1990s following their findings, led to the belief that ''Kneallhazia solenopsae'' could be used as a biological control agent to try to address the devastating impact of the imported fire ant. In 2008, Sokolova and Fuxa referred to newer molecular, morphological and life-cycle data and proposed that it be renamed in a new combination in a ...

Fungi
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microsporidia
Microsporidia are a group of spore-forming unicellular parasites. These spores contain an extrusion apparatus that has a coiled polar tube ending in an anchoring disc at the apical part of the spore. They were once considered protozoans or protists, but are now known to be fungi, or a sister group to fungi. These fungal microbes are obligate eukaryotic parasites that use a unique mechanism to infect host cells. They have recently been discovered in a 2017 Cornell study to infect Coleoptera on a large scale. So far, about 1500 of the probably more than one million species are named. Microsporidia are restricted to animal hosts, and all major groups of animals host microsporidia. Most infect insects, but they are also responsible for common diseases of crustaceans and fish. The named species of microsporidia usually infect one host species or a group of closely related taxa. Approximately 10 percent of the species are parasites of vertebrates —several species, most of which are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Solenopsis Invicta
The red imported fire ant (''Solenopsis invicta''), also known as the fire ant or RIFA, is a species of ant native to South America. A member of the genus '' Solenopsis'' in the subfamily Myrmicinae, it was described by Swiss entomologist Felix Santschi as a variant of '' S. saevissima'' in 1916. Its current specific name ''invicta'' was given to the ant in 1972 as a separate species. However, the variant and species were the same ant, and the name was preserved due to its wide use. Though South American in origin, the red imported fire ant has been accidentally introduced in Australia, New Zealand, several Asian and Caribbean countries, and the United States. The red imported fire ant is polymorphic, as workers appear in different shapes and sizes. The ant's colours are red and somewhat yellowish with a brown or black gaster, but males are completely black. Red imported fire ants are dominant in altered areas and live in a wide variety of habitats. They can be found in rain f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solenopsis Richteri
The black imported fire ant (''Solenopsis richteri''), or simply BIFA, is a species of ant in the genus '' Solenopsis'' (fire ants). It was long thought to either be a subspecies or a color variation of ''Solenopsis invicta'' (the red imported fire ant The red imported fire ant (''Solenopsis invicta''), also known as the fire ant or RIFA, is a species of ant native to South America. A member of the genus '' Solenopsis'' in the subfamily Myrmicinae, it was described by Swiss entomologist Fel ..., or simply RIFA), but is now recognized as its own species with a demonstratively different range and living habits. BIFA seem to be more tolerant of cold and a less dominant species than RIFA. Due to the BIFA higher body content of water than the RIFA conclusions demonstrate the certain factor plays a role in their differences of living regions. The species is native to South America, but has been introduced to North America. In the United States, the official assessment is that ...

Journal Of Invertebrate Pathology
The ''Journal of Invertebrate Pathology'' is a peer-reviewed scientific journal publishing research on the induction and pathogenesis of diseases of invertebrates, owned by Academic Press (part of Elsevier). The journal publishes the results of physiological, morphological, genetic, immunological, and ecological studies as related to the etiologic agents of diseases of invertebrates, including the suppression of diseases in beneficial species, and the use of diseases in controlling undesirable species. It was founded by American microbiologist Edward Arthur Steinhaus in 1959 as the ''Journal of Insect Pathology'', renamed in 1965, and in 1968 adopted as the official journal of the Society for Invertebrate Pathology shortly after it was also founded by Steinhaus.

Biological Control Agent
Biological control or biocontrol is a method of controlling pests, such as insects, mites, weeds, and plant diseases, using other organisms. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role. It can be an important component of integrated pest management (IPM) programs. There are three basic strategies for biological pest control: classical (importation), where a natural enemy of a pest is introduced in the hope of achieving control; inductive (augmentation), in which a large population of natural enemies are administered for quick pest control; and inoculative (conservation), in which measures are taken to maintain natural enemies through regular reestablishment. Natural enemies of insect pests, also known as biological control agents, include predators, parasitoids, pathogens, and competitors. Biological control agents of plant diseases are most often referred to as antagonists. Biologic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hymenoptera
Hymenoptera is a large order (biology), order of insects, comprising the sawfly, sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are Parasitoid wasp, parasitic. Females typically have a special ovipositor for inserting eggs into hosts or places that are otherwise inaccessible. This ovipositor is often modified into a stinger. The young develop through holometabolism (complete metamorphosis (biology), metamorphosis)—that is, they have a wormlike larval stage and an inactive pupal stage before they mature. Etymology The name Hymenoptera refers to the wings of the insects, but the original derivation is ambiguous. All references agree that the derivation involves the Ancient Greek language, Ancient Greek wikt:πτερόν, πτερόν (''pteron'') for wing. The Ancient Greek wikt:ὑμήν, ὑμήν (''hymen'') for membrane provides a plausible etymology for the term bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parasitology (journal)
''Parasitology'' is a peer-reviewed scientific journal covering the area of parasitology, including the biochemistry, molecular biology, genetics, ecology and epidemiology of eukaryotic parasites, and the relationship between the host and the parasite.
