Yersinia Entomophaga
''Yersinia entomophaga'' is a species of bacteria that was originally isolated from the diseased larvae of the New Zealand grass grub, ''Costelytra zealandica''. The type strain is MH96 (= DSM 22339 = ATCC BAA-1678). It is currently being studied for biological pest control of insect pests like the porina moth, '' Wiseana cervinata''. Etymology The name is derived from ''entomon'', adj., cut up, segmented animal (used to refer to an insect) and ''phagos'' (voracious eater); N.L. fem. n. entomophaga insect eater. References External linksLPSN: Species Yersinia entomophaga entomophaga ''Entomophaga'' is a genus of flies in the family Tachinidae. It was reviewed by T. Tachi and H. Shima in 2006 and was found to be paraphyletic; it was also found to form a monophyletic group with '' Proceromyia''. Species *'' E. exoleta'' ( Me ...

Larvae
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are immobil ...

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

Costelytra Zealandica
''Costelytra zealandica'' (commonly known as the grass grub) is a species of scarab beetle found in forested areas of greater Wellington Greater Wellington, also known as the Wellington Region (Māori: ''Te Upoko o te Ika''), is a non-unitary region of New Zealand that occupies the southernmost part of the North Island. The region covers an area of , and has a population of T .... It was originally described in 1846 by the British entomologist Adam White as ''Rhisotrogus zealandicus'' from a specimen obtained during the Ross expedition. The species is known to feed on roots of plants and trees, so is considered a pest for many farm pastures. Prior to 2016, the New Zealand grass grub was mischaracterized as ''C. zealandica''. In 2016 Coca-Abia and Romero-Samper found differences in syntype specimens between White's (1846) ''C. zealandica'' and Given's (1952) description and revised the species name of the latter to '' Costelytra giveni'' after Given.

Biological Pest Control
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] |
Wiseana Cervinata
''Wiseana cervinata'', a porina moth, is a species of moth belonging to the family Hepialidae. It was described by Francis Walker in 1865 and is endemic to New Zealand. The wingspan is 34–38 mm for males and 44–55 mm for females. The colour of the forewings varies from pale tan to blackened. Adults are on wing from September to March. The larvae feed on ''Trifolium'' species and various grass Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns an ...es. The interactions of this species with the Māori food crop kūmara has also been investigated, indicating that this species may have fed on kūmara in traditional kūmara gardens.

Yersinia
''Yersinia'' is a genus of bacteria in the family Yersiniaceae. ''Yersinia'' species are Gram-negative, coccobacilli bacteria, a few micrometers long and fractions of a micrometer in diameter, and are facultative anaerobes. Some members of ''Yersinia'' are pathogenic in humans; in particular, '' Y. pestis'' is the causative agent of the plague. Rodents are the natural reservoirs of ''Yersinia''; less frequently, other mammals serve as the host. Infection may occur either through blood (in the case of ''Y. pestis'') or in an alimentary fashion, occasionally via consumption of food products (especially vegetables, milk-derived products, and meat) contaminated with infected urine or feces. Speculations exist as to whether or not certain ''Yersinia'' can also be spread by protozoonotic mechanisms, since ''Yersinia'' species are known to be facultative intracellular parasites; studies and discussions of the possibility of amoeba-vectored (through the cyst form of the protozoan) ''Y ...
