Pest (organism)
A pest is any animal or plant harmful to humans or human concerns. The term is particularly used for creatures that damage crops, livestock, and forestry or cause a nuisance to people, especially in their homes. Humans have modified the environment for their own purposes and are intolerant of other creatures occupying the same space when their activities impact adversely on human objectives. Thus, an elephant is unobjectionable in its natural habitat but a pest when it tramples crops. Some animals are disliked because they bite or sting; snake Snakes are elongated, Limbless vertebrate, limbless, carnivore, carnivorous reptiles of the suborder Serpentes . Like all other Squamata, squamates, snakes are ectothermic, amniote vertebrates covered in overlapping Scale (zoology), scales. Ma ...s, wasps, ants, bed bugs, fleas and ticks belong in this category. Others enter the home; these include houseflies, which land on and contaminate food, beetles, which tunnel into the woodwor ...

Soybean Aphid
The soybean aphid (''Aphis glycines'') is an insect pest of soybean (''Glycine max'') that is exotic to North America. The soybean aphid is native to Asia. It has been described as a common pest of soybeans in China and as an occasional pest of soybeans in Indonesia, Japan, Korea, Malaysia, the Philippines, and Thailand. The soybean aphid was first documented in North America in Wisconsin in July 2000. Ragsdale ''et al.'' (2004) noted that the soybean aphid probably arrived in North America earlier than 2000, but remained undetected for a period of time. Venette and Ragsdale (2004) suggested that Japan probably served as the point of origin for the soybean aphid's North American invasion. By 2003, the soybean aphid had been documented in Delaware, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Michigan, Minnesota, Mississippi, Missouri, Nebraska, New York, North Dakota, Ohio, Pennsylvania, South Dakota, Virginia, West Virginia, and Wisconsin. Together, these states accounted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aphis Gossypii
''Aphis gossypii'' is a tiny insect, an aphid ("greenfly") in the superfamily Aphidoidea in the order Hemiptera. It is a true bug and sucks sap from plants. It is a widely distributed pest of a variety of agricultural crops in the families Cucurbitaceae, Rutaceae and Malvaceae. Common names include cotton aphid, melon aphid and melon and cotton aphid. Distribution It is not known where this species originated, but it is now found in tropical and temperate regions throughout the world except extreme northern areas. It is common in North and South America, Central Asia, Africa, Australia, Brazil, East Indies, Mexico and Hawaii and in most of Europe. It is cosmopolitan in habitat. It thrives outdoors in southern Europe but survives only under glass in northern Europe. In the former Soviet Union it is found up to 54°N. Morphology The wingless female cotton aphid has an ovoid body about two millimetres long in varying shades of green. The legs are yellow, as are the antennae whic ...

Sternorrhyncha Genera
The Sternorrhyncha suborder of the Hemiptera contains the aphids, whiteflies, and scale insects, groups which were traditionally included in the now-obsolete order "Homoptera". "Sternorrhyncha" refers to the rearward position of the mouthparts relative to the head. Distributed worldwide, all members of this group are plant-feeders, many considered pests feeding on major crops and ornamental plants. Many exhibit modified morphology and/or life cycles, including phenomena such as flightless morphs, parthenogenesis, sexual dimorphism, and eusociality. Phylogeny The phylogeny of the extant Sternorrhyncha, inferred from analysis of small subunit (18S) ribosomal RNA, is shown in the cladogram. The evolutionary position of several fossil taxa are unclear. A suggested phylogeny is: Groups Well-known groups in the Sternorrhyncha include: * aphids – (Aphididae) * woolly and gall-making aphids (Eriosomatinae) * pine and spruce aphids (Adelgidae) * phylloxerans (Phylloxeridae, i ...

Helleborus Niger
''Helleborus niger'', commonly called Christmas rose or black hellebore, is an evergreen perennial flowering plant in the buttercup family, Ranunculaceae. It is poisonous. Although the flowers resemble wild roses (and despite its common name), Christmas rose does not belong to the rose family ( Rosaceae). Taxonomy The black hellebore was described by Carl Linnaeus in volume one of his '' Species Plantarum'' in 1753. The Latin specific name ''niger'' (black) may refer to the colour of the roots. There are two subspecies: ''H. niger'' subsp. ''niger'' and ''H. niger'' subsp. ''macranthus'', which has larger flowers (up to 3.75 in/9 cm across). In the wild, ''H. niger'' subsp. ''niger'' is generally found in mountainous areas in Switzerland, southern Germany, Austria, Slovenia, Croatia and northern Italy. ''Helleborus niger'' subsp. ''macranthus'' is found only in northern Italy and possibly adjoining parts of Slovenia. Description ''Helleborus niger'' is an ...

Aphis Citricola
''Aphis spiraecola'' is a species of aphid described in 1914 by Edith Marion Patch. Its common names include green citrus aphid, Spirea aphid, and apple aphid. It is distributed worldwide, and is most abundant in the United States. It has a diploid chromosome number of 2n=8. Discovery This species was first discovered by Edith Marion Patch in 1914. Patch discovered that '' A. pomi'' would feed and develop on ''Spiraea'' and ''A. spiraecola'' would feed and develop on ''Malus'' which confirmed that aphids were a highly variable species. Patch’s colonies on apple were decimated by a fungus so all transfer attempts to secondary hosts, which would have demonstrated the limited host range of ''A. pomi'', were made using ''A. spiraecola'' from ''Spiraea'' instead. Later she suggested using the names ''A. pomi'' and ''A. spiraecola'' on the basis of the plants on which they were found thus leading to the names each species is known by today. Another species, ''A. citricola'' was de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
