Gleditsia Triacanthos
The honey locust (''Gleditsia triacanthos''), also known as the thorny locust or thorny honeylocust, is a deciduous tree in the family Fabaceae, native to central North America where it is mostly found in the moist soil of river valleys. Honey locust is highly adaptable to different environments, has been introduced worldwide, and can be an aggressive, invasive species outside of its native range. Description The honey locust, ''Gleditsia triacanthos'', can reach a height of . They exhibit fast growth, but live a medium life span of about 120 years. The leaves are pinnately compound on older trees but bipinnately compound on vigorous young trees. The leaflets are (smaller on bipinnate leaves) and bright green. They turn yellow in the autumn. Honey locusts leaf out relatively late in spring, but generally slightly earlier than the black locust (''Robinia pseudoacacia''). The strongly scented, cream-colored flowers appear in late spring, in clusters emerging from the base o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Washington (state)
Washington (), officially the State of Washington, is a state in the Pacific Northwest region of the Western United States. Named for George Washington—the first U.S. president—the state was formed from the western part of the Washington Territory, which was ceded by the British Empire in 1846, by the Oregon Treaty in the settlement of the Oregon boundary dispute. The state is bordered on the west by the Pacific Ocean, Oregon to the south, Idaho to the east, and the Canadian province of British Columbia to the north. It was admitted to the Union as the 42nd state in 1889. Olympia is the state capital; the state's largest city is Seattle. Washington is often referred to as Washington state to distinguish it from the nation's capital, Washington, D.C. Washington is the 18th-largest state, with an area of , and the 13th-most populous state, with more than 7.7 million people. The majority of Washington's residents live in the Seattle metropolitan area, the center of trans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleistocene Megafauna
Pleistocene megafauna is the set of large animals that lived on Earth during the Pleistocene epoch. Pleistocene megafauna became extinct during the Quaternary extinction event resulting in substantial changes to ecosystems globally. The role of humans in causing Pleistocene megafaunal extinctions is controversial. Megafauna are any animals with an adult body weight of over . Pleistocene megafauna include the straight-tusked elephant, cave bear (''Ursus spelaeus''), interglacial rhinoceros (''Stephanorhinus''), heavy-bodied Asian antelope ('' Spirocerus''), Eurasian hippopotamuses, woolly rhinoceros, mammoths, giant deer, sabre-toothed cat (''Homotherium''), cave lion, and the leopard in Europe. Paleoecology The last glacial period, commonly referred to as the 'Ice Age', spanned 125,000 to 14,500 years ago and was the most recent glacial period within the current ice age which occurred during the final years of the Pleistocene epoch. The Ice Age reached its peak during the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Traditional Medicine
Traditional medicine (also known as indigenous medicine or folk medicine) comprises medical aspects of traditional knowledge that developed over generations within the folk beliefs of various societies, including indigenous peoples, before the era of modern medicine. The World Health Organization (WHO) defines traditional medicine as "the sum total of the knowledge, skills, and practices based on the theories, beliefs, and experiences indigenous to different cultures, whether explicable or not, used in the maintenance of health as well as in the prevention, diagnosis, improvement or treatment of physical and mental illness". Traditional medicine is often contrasted with scientific medicine. In some Asian and African countries, up to 80% of the population relies on traditional medicine for their primary health care needs. When adopted outside its traditional culture, traditional medicine is often considered a form of alternative medicine. Practices known as traditional medicines ...

Honey
Honey is a sweet and viscous substance made by several bees, the best-known of which are honey bees. Honey is made and stored to nourish bee colonies. Bees produce honey by gathering and then refining the sugary secretions of plants (primarily floral nectar) or the secretions of other insects, like the honeydew of aphids. This refinement takes place both within individual bees, through regurgitation and enzymatic activity, as well as during storage in the hive, through water evaporation that concentrates the honey's sugars until it is thick and viscous. Honey bees stockpile honey in the hive. Within the hive is a structure made from wax called honeycomb. The honeycomb is made up of hundreds or thousands of hexagonal cells, into which the bees regurgitate honey for storage. Other honey-producing species of bee store the substance in different structures, such as the pots made of wax and resin used by the stingless bee. Honey for human consumption is collected from wild ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unripe Honey Locust Pods
Ripening is a process in fruits that causes them to become more palatable. In general, fruit becomes sweeter, less green, and softer as it ripens. Even though the acidity of fruit increases as it ripens, the higher acidity level does not make the fruit seem tarter. This effect is attributed to the Brix-Acid Ratio. Climacteric fruits ripen after harvesting and so some fruits for market are picked green (e.g. bananas and tomatoes). Underripe fruits are also fibrous, not as juicy, and have tougher outer flesh than ripe fruits (see Mouth feel). Eating unripe fruit can lead to stomachache or stomach cramps, and ripeness affects the palatability of fruit. Science 1 Methylcyclopropene is used as a synthetic 127x127px, leftDeveloping fruits produce compounds like alkaloids and tannins. These compounds are antifeedants, meaning that they discourage animals who would eat them while they are still ripening. This mechanism is used to make sure that fruit isn't eaten before the seeds ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monocropping
In agriculture, monocropping is the practice of growing a single crop year after year on the same land. Maize, soybeans, and wheat are three common crops often monocropped. Monocropping is also referred to as continuous cropping, as in "continuous corn." Monocropping allows for farmers to have consistent crops throughout their entire farm. They can plant only the most profitable crop, use the same seed, pest control, machinery, and growing method on their entire farm, which may increase overall farm profitability. Diversity can be added both in time, as with a crop rotation or sequence, or in space, with a polyculture or intercropping (see table below). Note that the distinction between monoculture and polyculture is not the same as between monocropping and intercropping. The first two describe diversity in ''space'', as does intercropping. Monocropping and crop rotation describe diversity over ''time''. This is frequently a source of confusion, even in scientific journal articles. ...

Vermin
Vermin (colloquially varmint(s) or varmit(s)) are pests or nuisance animals that spread diseases or destroy crops or livestock. Since the term is defined in relation to human activities, which species are included vary by region and enterprise. The term derives from the Latin ''vermis'' (worm), and was originally used for the worm-like larvae of certain insects, many of which infest foodstuffs. The term ''varmint'' (and ''vermint'') has been found in sources from c. 1530–1540s. Definition The term "vermin" is used to refer to a wide scope of organisms, including rodents (such as rats), cockroaches, termites, bed bugs, ferrets, stoats, Sable, sables, pigeons, and occasionally foxes. Historically, in the 16th and 17th century, the expression also became used as a derogatory term associated with groups of persons typically plagued by vermin, namely beggars and Vagrancy (people), vagabonds, and more generally Poverty, the poor. Disease-carrying rodents and insects are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gall
Galls (from the Latin , 'oak-apple') or ''cecidia'' (from the Greek , anything gushing out) are a kind of swelling growth on the external tissues of plants, fungi, or animals. Plant galls are abnormal outgrowths of plant tissues, similar to benign tumors or warts in animals. They can be caused by various parasites, from viruses, fungi and bacteria, to other plants, insects and mites. Plant galls are often highly organized structures so that the cause of the gall can often be determined without the actual agent being identified. This applies particularly to some insect and mite plant galls. The study of plant galls is known as cecidology. In human pathology, a gall is a raised sore on the skin, usually caused by chafing or rubbing. Causes of plant galls Insects and mites Insect galls are the highly distinctive plant structures formed by some herbivorous insects as their own microhabitats. They are plant tissue which is controlled by the insect. Galls act as both the habitat a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canker
A plant canker is a small area of dead tissue, which grows slowly, often over years. Some cankers are of only minor consequence, but others are ultimately lethal and therefore can have major economic implications for agriculture and horticulture. Their causes include a wide range of organisms as fungi, bacteria, mycoplasmas and viruses. The majority of canker-causing organisms are bound to a unique host species or genus, but a few will attack other plants. Weather and animals can spread canker, thereby endangering areas that have only slight amount of canker. Although fungicides or bactericides can treat some cankers, often the only available treatment is to destroy the infected plant to contain the disease. Examples * Apple canker, caused by the fungus ''Neonectria galligena'' * Ash bacterial canker, now understood to be caused by the bacterium '' Pseudomonas savastanoi'', rather than ''Pseudomonas syringae''. After DNA-relatedness studies ''Pseudomonas savastanoi'' has bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spider Mite
Spider mites are members of the Tetranychidae family, which includes about 1,200 species. They are part of the subclass Acari (mites). Spider mites generally live on the undersides of leaves of plants, where they may spin protective silk webs, and they can cause damage by puncturing the plant cells to feed. Spider mites are known to feed on several hundred species of plants. Description Spider mites are less than in size and vary in color. They lay small, spherical, initially transparent eggs and many species spin silk webbing to help protect the colony from predators; they get the "spider" part of their common name from this webbing. Life cycle Hot, dry conditions are often associated with population build-up of spider mites. Under optimal conditions (approximately 27 °C), the two-spotted spider mite can hatch in as little as 3 days, and become sexually mature in as little as 5 days. One female can lay up to 20 eggs per day and can live for 2 to 4 weeks, laying hundred ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mimosa Webworm
''Homadaula anisocentra'', also known as the mimosa webworm, is a species of moth in the family Galacticidae. It is considered a pest of ornamental plants. They attack the leaves of mimosa (''Albizia julibrissin'') and honeylocust (''Gleditsia triacanthos''). This species was introduced into the United States from China China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and ... in the 1940s. Description Adults are about long. They are silvery gray in color and have wings covered with small, black dots. The larvae are approximately in length and are green to dark brown color. The larvae have white stripes. References External links Images and information Galacticidae Moths described in 1922 Moths of Japan {{Yponomeutoidea-stub ...

Spongy Moth
''Lymantria dispar'', also known as the gypsy moth or the spongy moth, is a species of moth in the family Erebidae. ''Lymantria dispar'' is subdivided into several subspecies, with subspecies such as ''L. d. dispar'' and ''L. d. japonica'' being clearly identifiable without ambiguity. ''Lymantria dispar'' has been introduced to several continents and is now found in Europe, Africa, Asia, North America and South America. The polyphagous larvae live on a variety of deciduous and coniferous trees and can cause severe damage in years of mass reproduction. Due to these features, ''Lymantria dispar'' is listed among the world's 100 worst invasive alien species. Etymology The name “gypsy moth” does not have conclusive origins, however it has been in use since 1908. Moths of the subfamily Lymantriinae are commonly called tussock moths due to the tussock-like tufts of hair on the caterpillars.The Gypsy Moth: Research Toward Integrated Pest Management, United States Department of ...
