Soybean Aphid
The soybean aphid (''Aphis glycines'') is an insect Pest (organism), pest of soybean (''Glycine max'') that is exotic species, exotic to North America. The soybean aphid is native to Asia. It has been described as a common pest (organism), 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 (U.S. state), Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Michigan, Minnesota, Mississippi, Missouri, Nebraska, New York (state), New York, North Dakota, Ohio, Pennsylvania ...

Black Bean Aphid
The black bean aphid (''Aphis fabae'') is a small black insect in the genus ''Aphis'', with a broad, soft body, a member of the order Hemiptera. Other common names include blackfly, bean aphid, and beet leaf aphid. In the warmer months of the year, it is found in large numbers on the undersides of leaves and on the growing tips of host plants, including various agricultural crops and many wild and ornamental plants. Both winged and wingless forms exist, and at this time of year, they are all females. They suck sap from stems and leaves and cause distortion of the shoots, stunted plants, reduced yield, and spoiled crops. This aphid also acts as a vector for viruses that cause plant disease, and the honeydew it secretes may encourage the growth of sooty mould. It breeds profusely by live birth, but its numbers are kept in check, especially in the later part of the summer, by various predatory and parasitic insects. Ants feed on the honeydew it produces, and take active steps to re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helleborus Niger
''Helleborus niger'', commonly called Christmas rose or black hellebore, is an evergreen perennial flowering plant in the buttercup family, Ranunculaceae. It is one of about 20 species from the genus Hellebore. It is a poisonous cottage garden favourite because it flowers in the depths of winter. 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'' ...

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 desc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Valerian (herb)
Valerian (''Valeriana officinalis'', Caprifoliaceae) is a perennial flowering plant native to Eurasia. It produces a catnip-like response in cats. Crude Extract, extracts of valerian root may have sedative and anxiolytic effects; however, the clinical evidence is mixed and debated. It is commonly sold as dietary supplement to promote sleep. A dry ethanol extract of valerian root has been recognized as a medicine for adults with mild symptoms by the European Medicines Agency. Names The name of the herb is derived from the personal name ''Valeria (gens), Valeria'' and the Latin verb (to be strong, healthy). Other names used for this plant include garden valerian (to distinguish it from other ''Valeriana'' species), garden heliotrope (although not related to ''Heliotropium''), setwall (though this originally meant zedoary, from which it is etymologically derived) and all-heal (which is also used for plants in the genus ''Stachys'').

Aphis Pomi
''Aphis pomi'', commonly known as the apple aphid (the literal meaning of its binomial name), or the green apple aphid, is a true bug in the family Aphididae. It is found on young growth of apple trees and on other members of the rose family where it feeds by sucking sap. Reproduction is mainly by parthenogenesis, in which unmated females give birth to live young. Description Wingless females have a pear-shaped bright green or yellowish-green body, undusted with wax particles, and grow to a maximum length of about . The cauda (tail-like elongation of the body) and cornicles are black and the antennae and legs are pale with brown tips. Winged females have a black thorax and green abdomen, often with three pairs of blackish spots on the front three segments and dark semicircular spots in front of and behind the cornicles. Distribution ''Aphis pomi'' has a widespread distribution in Europe, western Asia as far east as India and Pakistan, North Africa and North America. In Israel an ...

Aphis Nerii
''Aphis nerii'' is an aphid of the Family (biology), family Aphididae. Its common names include oleander aphid, milkweed aphid, sweet pepper aphid, and nerium aphid. Distribution The oleander aphid is widespread in regions with tropical and Mediterranean climates. In Poland, oleander aphid has only been reported from a Greenhouse, glasshouse. Small populations of oleander aphid are present in gardens in London, England. Lifecycle Female aphids lay live young (nymphs), a process known as viviparity. Female aphids reproduce by parthenogenesis. Males have never been observed in the wild but have been produced under laboratory conditions. Females may be Aptery, wingless or winged (alate), the production of the alate form occurs at a higher rate in regions where the aphid must migrate to temporary hosts each year. Oleander aphid has a wide range of hosts, but mainly feeds on plants in the Apocynaceae, dogbane family, including Asclepias, milkweeds, Nerium oleander, oleander and Vinc ...
