Johan Christian Fabricius
Johann Christian Fabricius (7 January 1745 – 3 March 1808) was a Danish zoologist, specialising in "Insecta", which at that time included all arthropods: insects, arachnids, crustaceans and others. He was a student of Carl Linnaeus, and is considered one of the most important entomologists of the 18th century, having named nearly 10,000 species of animals, and established the basis for the modern insect classification. Biography Johann Christian Fabricius was born on 7 January 1745 at Tønder in the Duchy of Schleswig, where his father was a doctor. He studied at the gymnasium at Altona and entered the University of Copenhagen in 1762. Later the same year he travelled together with his friend and relative Johan Zoëga to Uppsala, where he studied under Carl Linnaeus for two years. On his return, he started work on his , which was finally published in 1775. Throughout this time, he remained dependent on subsidies from his father, who worked as a consultant at Frederiks H ...

Phenacoccus Solenopsis
''Phenacoccus solenopsis'', the cotton mealybug or solenopsis mealybug, is a species of mealybug in the family Pseudococcidae. Having originated in North America, it has spread to other parts of the world and become a major pest of cotton crops. Description The adult female is ellipsoidal in shape, about long and wide, with a convex dorsal surface and a flat ventral surface. The body is yellowish-grey but this is largely obscured by the waxy secretions that cover the body, although the segmentation can still be seen. There is a transverse, darker bar on the dorsal surface. There are 18 pairs of very short, lateral wax filaments, and several slightly longer caudal filaments. Distribution and hosts This species was discovered and first described in New Mexico in 1898 by the American entomologist J. D. Tinsley; he found it in an underground ants' nest where it was feeding on the roots and stems of '' Boerhavia spicata'' and '' Kallstroemia californica'', and described it from stem ...

Leucaspis Coniferarum
In Greek mythology, Leucaspis () was a Sicani prince who entered into combat with Heracles when he passed through Sicily, on return from the country of Geryon In Greek mythology, Geryon ( ; , genitive ), also Geryone (, or ), son of Chrysaor and Callirrhoe, the grandson of Medusa and the nephew of Pegasus, was a fearsome giant who dwelt on the island Erytheia of the mythic Hesperides in the far .... In the combat Leucaspis died along with a great number of noble compatriots, and he became a cult. In Book Six, line 334 of the ''Aeneid'', Vergil mentions Leucaspis as one of the souls deprived of death rites and blocked from crossing the River Styx.

Aspidiotus Destructor
''Aspidiotus destructor'', the coconut scale, is a species of armoured scale insect in the family Diaspididae, found in many tropical and subtropical parts of the world. It is a serious pest of coconut and banana, and attacks a range of other fruiting trees and ornamental plants. Description All but the first instar nymphs live under the protection of a waxy test or scale and remain in one place. First instar nymphs have legs and move about looking for somewhere to settle. Second instar and adult females have rounded, flattish tests up to in diameter. They have no eyes or appendages, and their soft yellow bodies are visible through the translucent test, giving them the appearance of miniature fried eggs. Males have smaller, more elongated tests, and pass through a pseudo-pupal stage before metamorphosing into reddish, gnat-like insects with eyes, antennae, legs and wings, but no mouthparts.

Aonidiella Citrina
''Aonidiella citrina'' or yellow scale is an armored scale insect from the family Diaspididae. It feeds by sucking sap from plants in a number of plant families, but is mostly known for being a pest of citrus. Description Armoured scales are so-called because they are covered by a hard, plate-like structure, the scale. The adult female yellow scale insect is concealed under a thin, pale circular scale through which its yellowish body colour can be seen. The female is legless and remains in the same location permanently, anchored to the surface. The male is a similar colour and has an elongate oval scale. The exuviae (shed nymphal skins) are located near the centre in the female scale but are near one end in the male insect. When the adult male emerges from under its scale after four moults, it has limbs and a single pair of wings and is able to fly rather weakly; it lives for only a few hours, and its sole purpose is to find and mate with a female. Life cycle The adult female ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Adelges Joshii
''Adelges'' is a genus of insects which feed on conifers. They have complex life cycles, some species feeding exclusively on spruce, others feeding on spruce and an alternate conifer. However, galls characteristic of each species are formed only on spruce. Six generations are usually needed to complete the 2-year cycle, and in the case of species having an alternate host, winged adults about 2 mm long are formed only in the generations that move from one host to the other. The spruce gall adelgid (''Adelges lariciatus'' Patch) occurs in alternate years on spruce and larch from Alberta to the Maritimes and in adjacent parts of the United States. The pale spruce gall adelgid (''Adelges strobilobius'' Kaltenbach) has a similar range but prefers black spruce or red spruce to white spruce. Species include: * ''Adelges abietis'' (Pineapple gall adelgid) * ''Adelges cooleyi'' (Gall adelgid) * ''Adelges piceae'' (Balsam woolly adelgid) * ''Adelges tsugae'' (Hemlock woolly adelgid ...

Bemisia Tabaci
The silverleaf whitefly (''Bemisia tabaci'', also informally referred to as the sweet potato whitefly) is one of several species of whitefly that are currently important agricultural pests. A review in 2011 concluded that the silverleaf whitefly is actually a species complex containing at least 40 morphologically indistinguishable species. The silverleaf whitefly thrives worldwide in tropical, subtropical, and less predominately in temperate habitats. Cold temperatures kill both the adults and the nymphs of the species. The silverleaf whitefly can be confused with other insects such as the common fruitfly, but with close inspection, the whitefly is slightly smaller and has a distinct wing color that helps to differentiate it from other insects. While the silverleaf whitefly had been known in the United States since 1896, in the mid-1980s an aggressive strain appeared in poinsettia crops in Florida. For convenience that strain was referred to as (biotype B), to distinguish it fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amrasca Biguttula
''Amrasca biguttula'', commonly known as the cotton jassid, is a subspecies of leafhopper belonging to the subfamily Typhlocybinae of family Cicadellidae. It is a pest of cotton, okra, and other crops in southern Asia and West Africa. Description The adult cotton jassid is a long and slender insect about in length. It is yellowish-green, with a conspicuous black spot on either side of the head and another near the tip of the fore wing. The head is pale green and the membranous wings transparent and iridescent. On leaf surfaces, the insect tends to move about diagonally, and when disturbed it immediately jumps and flies away. Life cycle Leafhoppers undergo direct development from nymph to adult without undergoing metamorphosis. On okra, eggs are mainly oviposited inside the tissue of leaf blades, but may also be laid in leaf stalks or in soft twigs. The eggs hatch in six or seven days. There are five nymphal instars, developing over a period of about seven days. Nymphs are win ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
