Mesocyclops Aspericornis
''Mesocyclops aspericornis'' is a freshwater copepod species in the genus '' Mesocyclops'' found in the tropics. It was collected from Sumatra, Singapore and Hawaii. Together with the mosquito species ''Toxorhynchites speciosus'', ''M. aspericornis'' forms a compatible predator pair for reduction of larval '' Aedes notoscriptus'' and ''Culex quinquefasciatus'' populations in tire habitats in Queensland. It has also been used in combination with '' Bacillus thuringiensis var. israelensis'' in controlling ''Aedes aegypti ''Aedes aegypti'', the yellow fever mosquito, is a mosquito that can spread dengue fever, chikungunya, Zika fever, Mayaro and yellow fever viruses, and other disease agents.

Mesocyclops
''Mesocyclops'' is a genus of copepod crustaceans in the family Cyclopidae. Because the various species of ''Mesocyclops'' are known to prey on mosquito larvae, it is used as a nontoxic and inexpensive form of biological mosquito control. Biological control Individuals of ''Mesocyclops'' can be easily harvested, bred and released into freshwater containers where the ''Aedes aegypti'' mosquito larvae (the vector of Dengue fever) live. A big advantage of the ''Mesocyclops'' is that it is possible to teach schoolchildren how to recognize and collect them so that communities are able to perform sustainable mosquito control without much professional or governmental assistance. A field trial in Vietnam has shown that large-scale elimination of ''Aedes aegypti'' larvae is possible. Because ''Mesocyclops'' is a host for the parasitic round worm Guinea worm (''Dracunculus medinensis'', the causative agent of dracunculiasis), this method is potentially hazardous in the small number of co ...

Toxorhynchites Speciosus
''Toxorhynchites speciosus'' is a mosquito species in the genus ''Toxorhynchites'' found in Australia. ''Toxorhynchites'' larvae, a mosquito genus that does not suck blood, feed upon other mosquito larvae and are often found with tiger mosquito (''Aedes albopictus'') larvae. Together with ''Mesocyclops aspericornis'', ''T. speciosus'' forms a compatible predator pair for reduction of larval ''Aedes notoscriptus'' and ''Culex quinquefasciatus ''Culex'' is a genus of mosquitoes, several species of which serve as vectors of one or more important diseases of birds, humans, and other animals.

Aedes Notoscriptus
''Aedes'' is a genus of mosquitoes originally found in tropical and subtropical zones, but now found on all continents except perhaps Antarctica. Some species have been spread by human activity: '' Aedes albopictus'', a particularly invasive species, was spread to the New World, including the United States, in the 1980s, by the used-tire trade. First described and named by German entomologist Johann Wilhelm Meigen in 1818, the generic name comes from the Ancient Greek ἀηδής, ''aēdēs'', meaning "unpleasant" or "odious". The type species for ''Aedes'' is '' Aedes cinereus''.. Systematics and phylogeny The genus was named by Johann Wilhelm Meigen in 1818. The generic name comes from the Ancient Greek ἀηδής, ''aēdēs'', meaning "unpleasant" or "odious". As historically defined, the genus contains over 700 species (see the list of ''Aedes'' species). The genus has been divided into several subgenera (''Aedes'', '' Diceromyia'', '' Finlaya'', ''Stegomyia'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Culex Quinquefasciatus
''Culex'' is a genus of mosquitoes, several species of which serve as vectors of one or more important diseases of birds, humans, and other animals. The diseases they vector include arbovirus infections such as West Nile virus, Japanese encephalitis, or St. Louis encephalitis, but also filariasis and avian malaria. They occur worldwide except for the extreme northern parts of the temperate zone, and are the most common form of mosquito encountered in some major U.S. cities, such as Los Angeles. Etymology In naming this genus, Carl Linnaeus appropriated the nonspecific Latin term for a midge or gnat: '. Description Depending on the species, the adult ''Culex'' mosquito may measure from . The adult morphology is typical of flies in the suborder Nematocera with the head, thorax, and abdomen clearly defined and the two forewings held horizontally over the abdomen when at rest. As in all Diptera capable of flight, the second pair of wings is reduced and modified into tiny, inc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bacillus Thuringiensis Var
''Bacillus'' (Latin "stick") is a genus of Gram-positive, rod-shaped bacteria, a member of the phylum '' Bacillota'', with 266 named species. The term is also used to describe the shape (rod) of other so-shaped bacteria; and the plural ''Bacilli'' is the name of the class of bacteria to which this genus belongs. ''Bacillus'' species can be either obligate aerobes which are dependent on oxygen, or facultative anaerobes which can survive in the absence of oxygen. Cultured ''Bacillus'' species test positive for the enzyme catalase if oxygen has been used or is present. ''Bacillus'' can reduce themselves to oval endospores and can remain in this dormant state for years. The endospore of one species from Morocco is reported to have survived being heated to 420 °C. Endospore formation is usually triggered by a lack of nutrients: the bacterium divides within its cell wall, and one side then engulfs the other. They are not true spores (i.e., not an offspring). Endospore f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aedes Aegypti
''Aedes aegypti'', the yellow fever mosquito, is a mosquito that can spread dengue fever, chikungunya, Zika fever, Mayaro and yellow fever viruses, and other disease agents. The mosquito can be recognized by black and white markings on its legs and a marking in the form of a lyre on the upper surface of its thorax. This mosquito originated in Africa, but is now found in tropical, subtropical and temperate regions throughout the world. Biology ''Aedes aegypti'' is a long, dark mosquito which can be recognized by white markings on its legs and a marking in the form of a lyre on the upper surface of its thorax. Females are larger than males. Microscopically females possess small palps tipped with silver or white scales, and their antennae have sparse short hairs, whereas those of males are feathery. ''Aedes aegypti'' can be mixed up with Aedes albopictus without a magnifying glass: The latter have a white stripe on the top of the mid thorax. Males live off fruit and only the ...

Biological Control Agents Of Pest Insects
Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. Another major theme is evolution, which explains the unity and diversity of life. Energy processing is also important to life as it allows organisms to move, grow, and reproduce. Finally, all organisms are able to regulate their own internal environments. Biologists are able to study life at multiple levels of organization, from the molecular biology of a cell to the anatomy and physiology of plants and animals, and evolution of populations.Based on definition from: Hence, there are multiple subdisciplines within biology, each defined by the nature of their research questions and the tools that they use. Like other scientists, biologists use the scientific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crustaceans Described In 1906
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans ( Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) lim ...
