Aleurotrachelus Atratus
''Aleurotrachelus atratus'' better known as the palm-infesting whitefly is an invasive species that affects coconut palms. Originally, this species was only prevalent in Brazil and was known to feed on coconuts native to this country. Now, the species has migrated to the tropics and subtropics and is invasive in many other countries. Aleurotrachelus is one of the largest genus, containing 74 species. Description ''Aleurotrachelus atratus'' are small insects whose puparia have wax filaments that cover the bug in its entirety. ''A. Atratus'' are generally dark yellow with all four larval stages being black. Adult whiteflies are very small bugs with white wings. Females lay eggs on the underside directly onto plant leaves, and eventually, eggs become crawlers after 6 days. These nymphs remain on the same leaf for the rest of their development until they emerge as winged adults. This cycle takes about 3 weeks in favorable conditions, however, the whiteflies are able to survive i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...

Chlorosis
In botany, chlorosis is a condition in which leaves produce insufficient chlorophyll. As chlorophyll is responsible for the green color of leaves, chlorotic leaves are pale, yellow, or yellow-white. The affected plant has little or no ability to manufacture carbohydrates through photosynthesis and may die unless the cause of its chlorophyll insufficiency is treated and this may lead to a plant diseases called rusts, although some chlorotic plants, such as the albino ''Arabidopsis thaliana'' mutant ''ppi2'', are viable if supplied with exogenous sucrose. The word ''chlorosis'' is derived from the Greek ''khloros'' meaning "greenish-yellow", "pale green", "pale", "pallid", or "fresh". In viticulture, the most common symptom of poor nutrition in grapevines is the yellowing of grape leaves caused by chlorosis and the subsequent loss of chlorophyll. This is often seen in vineyard soils that are high in limestone such as the Italian wine region of Barolo in the Piedmont, the Spanish wi ...

Encarsia Formosa
''Encarsia formosa'' is a species of chalcidoid wasp and a well known parasitoid of greenhouse whitefly, one of the first to be used commercially for biological pest control, from the 1920s. They can use at least 15 species of whitefly as a host, including ''Bemisia tabaci'' and '' Aleyrodes proletella.'' The tiny females (about 0.6 mm long) are black with a yellow abdomen and opalescent wings. This species reproduces asexually via thelytoky induced by Wolbachia infection. Males are produced only rarely. They are slightly larger than females and are completely black in coloration. Life cycle Females deposit 50-100 eggs individually inside the bodies of nymphs or pupa A pupa ( la, pupa, "doll"; plural: ''pupae'') is the life stage of some insects undergoing transformation between immature and mature stages. Insects that go through a pupal stage are holometabolous: they go through four distinct stages in thei ...e of the host species. The wasp larvae develop throug ...

Minute Pirate Bug
Anthocoridae is a family of bugs, commonly called minute pirate bugs or flower bugs. Worldwide there are 500-600 species. Description Anthocoridae are 1.5–5 mm long and have soft, elongated oval, flat bodies, often patterned in black and white. The head is extended forward and the antennae are longer than the head and visible from above. They possess a piercing and sucking three-segmented beak or labium used to inject prey with digestive enzymes and consume food. In general appearance, they resemble soft bugs Miridae, but Anthocoridae differ by their possession of two ocelli as adults. Anthocorids possess two pairs of wings with hemelytra and membranous hindwings. Many species are referred to as insidious flower bugs or pirate bugs. The scientific name is a combination of the Greek words ''anthos'' "flower" and ''koris'' "bug". Habitat and behaviour Many species can be found in cryptic habitats such as galls, but can also be present in open surface environments. They ...

Big-eyed Bug
''Geocoris'' is a genus of insects in the family Geocoridae (although in the past the geocorids were subsumed as a subfamily under the family "Lygaeidae"). Commonly known as big-eyed bugs, the species in ''Geocoris'' are beneficial predators, but are often confused with the true chinch bug, which is a pest. There are more than 140 described species in ''Geocoris''. Description Big-eyed bugs are true bugs in the order Hemiptera. The two most common North American species are ''Geocoris pallens'' and ''Geocoris punctipes''. Both are predators and occur in many habitats, including fields, gardens, and turf grass. Big-eyed bugs are considered an important predator in many agricultural systems and feed on mites, insect eggs, and small insects such as pink bollworm, cabbage loopers, and whiteflies. Adult big-eyed bugs are small (about ) black, gray, or tan with proportionately large eyes. Eggs are deposited singly or in clusters on leaves near potential prey. They develop with incom ...

Ladybugs
Coccinellidae () is a widespread family of small beetles ranging in size from . They are commonly known as ladybugs in North America and ladybirds in Great Britain. Some entomologists prefer the names ladybird beetles or lady beetles as they are not true bugs. Many of the species have conspicuous aposematic colours and patterns, such as red with black spots, that warn potential predators that they are distasteful. The majority of the more than 6,000 described species are generally considered beneficial insects, because many prey on herbivorous hemipterans such as aphids or scale insects, which are agricultural pests. Many coccinellids lay their eggs directly in aphid and scale insect colonies, ensuring their larvae have an immediate food source. However, some species such as the herbivorous Mexican bean beetle are agricultural pests. Etymology The name ''coccinellids'', created by Pierre André Latreille, is derived from the Latin word ''coccineus'' meaning "scarlet". The na ...

Lacewings
The insect order Neuroptera, or net-winged insects, includes the lacewings, mantidflies, antlions, and their relatives. The order consists of some 6,000 species. Neuroptera can be grouped together with the Megaloptera and Raphidioptera in the unranked taxon Neuropterida (once known as Planipennia) including: alderflies, fishflies, dobsonflies, and snakeflies. Adult Neuropterans have four membranous wings, all about the same size, with many veins. They have chewing mouthparts, and undergo complete metamorphosis. Neuropterans first appeared during the Permian period, and continued to diversify through the Mesozoic era. During this time, several unusually large forms evolved, especially in the extinct family Kalligrammatidae, often called "the butterflies of the Jurassic" for their large, patterned wings. Anatomy and biology Neuropterans are soft-bodied insects with relatively few specialized features. They have large lateral compound eyes, and may or may not also have ocelli ...

Tropaeolum
''Tropaeolum'' , commonly known as nasturtium (; literally "nose-twister" or "nose-tweaker"), is a genus of roughly 80 species of annual and perennial herbaceous flowering plants. It was named by Carl Linnaeus in his book ''Species Plantarum'', and is the only genus in the family Tropaeolaceae. The nasturtiums received their common name because they produce an oil similar to that of watercress (''Nasturtium officinale''). The genus ''Tropaeolum'', native to South and Central America, includes several very popular garden plants, the most common being '' T. majus'', '' T. peregrinum'' and '' T. speciosum''. One of the hardiest species is '' T. polyphyllum'' from Chile, the perennial roots of which can survive the winter underground at elevations of . Plants in this genus have showy, often intensely bright flowers and rounded, peltate (shield-shaped) leaves with the petiole in the centre. The flowers are bisexual and zygomorphic, with five petals, a superior three-carpelled ov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dust Buster
The Black & Decker DustBuster (now stylized as DUSTBUSTER) is a cordless vacuum cleaner that was introduced in January 1979. Mark Proett and Carroll Gantz are listed as the inventors on the utility and design patents, respectively, assigned to Black & Decker for a cordless vacuum cleaner. Mark Proett was an engineer whose utility patent was for B&D's Model 9321 cordless vacuum cleaner, called the Spot Vac, a component of the Mod 4 series of power tools (shrub trimmer, lantern, grass shear, drill, and Spot Vac), all powered by a single, rechargeable, and interchangeable "energy pak" handle with batteries. The device uses suction power to pick up fine dirt and debris including pet hair. The design originated from the Apollo space mission, where NASA required a portable, self-contained drill capable of extracting core samples from the lunar surface. Black & Decker was tasked with the job, and developed a computer program to optimize the design of the drill's motor and ensure m ...

Arecaceae
The Arecaceae is a family of perennial flowering plants in the monocot order Arecales. Their growth form can be climbers, shrubs, tree-like and stemless plants, all commonly known as palms. Those having a tree-like form are called palm trees. Currently, 181 genera with around 2,600 species are known, most of which are restricted to tropical and subtropical climates. Most palms are distinguished by their large, compound, evergreen leaves, known as fronds, arranged at the top of an unbranched stem. However, palms exhibit an enormous diversity in physical characteristics and inhabit nearly every type of habitat within their range, from rainforests to deserts. Palms are among the best known and most extensively cultivated plant families. They have been important to humans throughout much of history. Many common products and foods are derived from palms. In contemporary times, palms are also widely used in landscaping. In many historical cultures, because of their importance as ...

Coconut Palm
The coconut tree (''Cocos nucifera'') is a member of the palm tree family (Arecaceae) and the only living species of the genus ''Cocos''. The term "coconut" (or the archaic "cocoanut") can refer to the whole coconut palm, the seed, or the fruit, which botanically is a drupe, not a nut. The name comes from the old Portuguese word '' coco'', meaning "head" or "skull", after the three indentations on the coconut shell that resemble facial features. They are ubiquitous in coastal tropical regions and are a cultural icon of the tropics. The coconut tree provides food, fuel, cosmetics, folk medicine and building materials, among many other uses. The inner flesh of the mature seed, as well as the coconut milk extracted from it, form a regular part of the diets of many people in the tropics and subtropics. Coconuts are distinct from other fruits because their endosperm contains a large quantity of clear liquid, called ''coconut water'' or ''coconut juice''. Mature, ripe coconuts ca ...
