Gonipterus Platensis
''Gonipterus platensis'' is a species of weevil in the family Curculionidae. It is commonly known as the eucalyptus snout beetle, the eucalyptus weevil or the gum tree weevil. It feeds and breeds on '' Eucalyptus'' trees and is endemic to Australia, though it is also found in New Zealand, North America, Hawaii, and western Europe. Description This weevil is greyish-brown with a light coloured transverse band. It is about thirteen millimetres long and not readily distinguishable from the closely related weevils, '' Gonipterus gibberus'', '' Gonipterus pulverulentus'', and ''Gonipterus scutellatus'', all of which share the same common names, as they have historically been confused with one another.Mapondera, T.S., Burgess, T., Matsuki, M. and Oberprieler, R.G.

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. 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. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists 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. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gonipterus Scutellatus
''Gonipterus scutellatus'' is a species of weevil in the family Curculionidae. It is commonly known as the eucalyptus snout beetle, the eucalyptus weevil or the gum tree weevil.

Beetles Of Australia
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard exoske ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gonipterini
Gonipterini is a tribe of weevils in the subfamily Curculioninae. The larvae and adults are usually found on eucalyptus trees, where they feed upon the foliage. The larvae are legless and slug-like in appearance. The adults have a broad body, and short stout rostrum. ''Gonipterus gibberus'' and ''Gonipterus scutellatus'' (eucalyptus weevil) were introduced from Australia to South America South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent. It can also be described as the southe ..., where they became pest species in eucalypt plantations. Control of ''Gonipterus'' in South America was largely achieved following the introduction from Australia of a small parasitic wasp that attacks the weevil's eggs, providing an example of biological control.

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] |
Anaphes Nitens
''Anaphes nitens'' is a species of fairyfly, a chalcid wasp in the family Mymaridae. Native to Australia, it is an egg parasitoid of the gum tree snout beetle (''Gonipterus scutellatus''), a pest of '' Eucalyptus'' trees, and has been used in biological pest control of that species. Description Like other species in its genus, ''Anaphes nitens'' is a tiny insect, not more than long. The hind wings are elongated and stalked, and there are short hairs fringing both pairs of wings. The head and body are black, the limbs are amber to brown and the wings are tinged with brown. Ecology ''Anaphes nitens'' is native to southeastern Australia. The adult wasps feed on nectar and honeydew, but the larvae are carnivorous and feed on the eggs of the gum tree snout beetle (''Gonipterus scutellatus''). Both this beetle and its larvae feed on the young leaves, buds and shoots of various species of ''Eucalyptus'', causing a slowing of growth of the tree, a contortion of the twigs and someti ...

Epicormic Shoot
An epicormic shoot is a shoot growing from an epicormic bud, which lies underneath the bark of a trunk, stem, or branch of a plant. Epicormic buds lie dormant beneath the bark, their growth suppressed by hormones from active shoots higher up the plant. Under certain conditions, they grow into active shoots, such as when damage occurs to higher parts of the plant, or light levels are increased following removal of nearby plants. Epicormic buds and shoots occur in many woody species, but are absent from many others, such as most conifers. Function Human horticultural practices that exploit epicormic growth rely on plants that have epicormic budding capabilities for regenerative function in response to crown damage, such as through wind or fire. Epicormic shoots are the means by which trees regrow after coppicing or pollarding, where the tree's trunk or branches are cut back on a regular cycle. These forestry techniques cannot be used on species which do not possess strong ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Weevil
Weevils are beetles belonging to the Taxonomic rank, superfamily Curculionoidea, known for their elongated snouts. They are usually small, less than in length, and Herbivore, herbivorous. Approximately 97,000 species of weevils are known. They belong to several families, with most of them in the family Curculionidae (the true weevils). It also includes Bark beetle, bark beetles, which while morphologically dissimilar to other weevils in lacking the distinctive snout, is a subfamily of Curculionidae. Some other beetles, although not closely related, bear the name "weevil", such as the Drugstore beetle, biscuit weevil (''Stegobium paniceum''), which belongs to the family Ptinidae. Many weevils are considered pests because of their ability to damage and kill crops. The grain or wheat weevil (''Sitophilus granarius'') damages stored cereal, grain, as does the maize weevil (''Sitophilus zeamais'') among others. The boll weevil (''Anthonomus grandis'') attacks cotton crops; it lays its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
