Pediobius Eubius
''Pediobius'' is a genus of hymenopteran insects of the chalcid wasp family Eulophidae. Like their relatives, the larvae of these diminutive wasps are parasitoids of various arthropods (mainly insects). Some ''Pediobius'' are used in biological pest control. There are over 200 species in the genus ''Pedobius'' and these include: *'' Pediobius eubius (Walker, 1839) *''Pediobius foveolatus'' Crawford, 1912 * '' Pediobius imbreus'' (Walker, 1846) * '' Pediobius lysis'' (Walker, 1839) * '' Pediobius metallicus'' (Nees Christian Gottfried Daniel Nees von Esenbeck (14 February 1776 – 16 March 1858) was a prolific German botanist, physician, zoologist, and natural philosopher.

Larva
A larva (; : larvae ) is a distinct juvenile form many animals undergo before metamorphosis into their next life stage. Animals with indirect development such as insects, some arachnids, amphibians, or cnidarians typically have a larval phase of their life cycle. A 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. In the case of smaller primitive arachnids, the larval stage differs by having three instead of four pairs of legs. 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 lar ...

Christian Gottfried Daniel Nees Von Esenbeck
Christian Gottfried Daniel Nees von Esenbeck (14 February 1776 – 16 March 1858) was a prolific Germany, German botanist, physician, zoologist, and natural philosopher. He was a contemporary of Goethe and was born within the lifetime of Carl Linnaeus, Linnaeus. He described approximately 7,000 plant species (almost as many as Linnaeus himself). His last official act as president of the German Academy of Natural Scientists Leopoldina was to admit Charles Darwin as a member. He was the author of numerous monographs on botany and zoology and majority of his best-known works deal with fungi. Biography Nees von Esenbeck was born in Schloss Reichenberg near Reichelsheim (Odenwald) in Hesse, Germany. He showed an early interest in science and, after receiving his primary education in Darmstadt, went on to the University of Jena and obtained his degree in biology (natural history) and medicine in 1800. He practiced as a physician for Francis I (Erbach-Erbach), but he had developed a gre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pediobius Foveolatus
''Pediobius foveolatus'' (James Chamberlain Crawford, Crawford) (Fig. 1 and 3), is a tiny exotic parasitoid wasp that is used for biological control of Mexican bean beetle, Mexican bean beetle, ''Epilachna varivestis'' (Fig. 2), an important insect pest of snap beans, lima beans, and sometimes soybeans mainly found at Integrated pest management, economic levels in the eastern United States. ''Pediobius foveolatus'' is in the family Eulophidae, and is the most successful biological control agent for Mexican bean beetle. This wasp only attacks beetle larvae, not eggs or adults. It is commonly used by smaller, organic growers; but is also mass released throughout the state of New Jersey, by their state department of agriculture.Stevens, L. M., A. L. Steinhauer and J. R. Coulson. 1975. "Suppression of Mexican bean beetle on soybeans with inoculative releases of Pediobius foveolatus." ''Environmental Entomology'' 4(6): 947–952.

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biological Pest Control
Biological control or biocontrol is a method of controlling pests, whether pest animals such as insects and mites, weeds, or pathogens affecting animals or plants by 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 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 insects play an important part in limiting the densities of potential pests. Biological control agents such as these include predators, parasitoids, pathogens, and com ...

Arthropod
Arthropods ( ) are invertebrates in the phylum Arthropoda. They possess an arthropod exoskeleton, exoskeleton with a cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate, a body with differentiated (Metamerism (biology), metameric) Segmentation (biology), segments, and paired jointed appendages. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. They form an extremely diverse group of up to ten million species. Haemolymph is the analogue of blood for most arthropods. An arthropod has an open circulatory system, with a body cavity called a haemocoel through which haemolymph circulates to the interior Organ (anatomy), organs. Like their exteriors, the internal organs of arthropods are generally built of repeated segments. They have ladder-like nervous systems, with paired Anatomical terms of location#Dorsal and ventral, ventral Ventral nerve cord, nerve cord ...

Parasitoid
In evolutionary ecology, a parasitoid is an organism that lives in close association with its host (biology), host at the host's expense, eventually resulting in the death of the host. Parasitoidism is one of six major evolutionarily stable strategy, evolutionary strategies within parasitism, distinguished by the fatal prognosis for the host, which makes the strategy close to predation. Among parasitoids, strategies range from living inside the host (''endoparasitism''), allowing it to continue growing before emerging as an adult, to Paralysis, paralysing the host and living outside it (''ectoparasitism''). Hosts can include other parasitoids, resulting in hyperparasitism; in the case of oak galls, up to five levels of parasitism are possible. Some parasitoids Behavior-altering parasite, influence their host's behaviour in ways that favour the propagation of the parasitoid. Parasitoids are found in a variety of Taxon, taxa across the insect superorder Endopterygota, whose compl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
