Megacyllene Robiniae
''Megacyllene robiniae'', commonly known as the locust borer, is a species of longhorn beetle endemic to eastern North America. It is a serious pest of ''Robinia pseudoacacia'', the black locust tree, with which it is sympatric. Etymology The specific name, ''robiniae'', is derived from the name ''Robinia'', which is the generic name of the black locust tree, ''Robinia pseudoacacia'', on which the larvae feed. The name ''Robinia'' was coined by Linnaeus to honor the royal French gardeners Jean Robin (father) and Vespasien Robin (son). Description From a distance, ''M. robiniae'' can easily be mistaken for a wasp or bee, due to its black and yellow striped pattern. It can also be mistaken for two closely related species: '' M. caryae'' and '' M. decora''. The adult beetle can be long, and it has a W-shaped third stripe on the elytra. The antennae of both sexes are dark brown to black. The male's antennae are two-thirds its body length, and the female's are one-half. The l ...

Johann Reinhold Forster
Johann Reinhold Forster (22 October 1729 – 9 December 1798) was a German Continental Reformed church, Reformed (Calvinist) pastor and natural history, naturalist of partially Scottish descent who made contributions to the early ornithology of Europe and North America. He is best known as the naturalist on James Cook's Second voyage of James Cook, second Pacific voyage, where he was accompanied by his son Georg Forster. These expeditions promoted the career of Johann Reinhold Forster and the findings became the bedrock of colonial professionalism and helped set the stage for the future development of anthropology and ethnology. They also laid the framework for general concern about the impact that alteration of the physical environment for European economic expansion would have on exotic societies. Biography Forster's family originated in the Lord Forrester, Lords Forrester in Scotland from where his great-grandfather had emigrated after losing most of his property during the ...

Beetles Of North America
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carbaryl
Carbaryl (1-naphthyl methylcarbamate) is a chemical in the carbamate family used chiefly as an insecticide. It is a white crystalline solid previously sold under the brand name Sevin, which was a trademark of the Bayer Company. The Sevin trademark has since been acquired by GardenTech, which has eliminated carbaryl from most Sevin formulations. Union Carbide discovered carbaryl and introduced it commercially in 1958. Bayer purchased Aventis CropScience in 2002, a company that included Union Carbide pesticide operations. Carbaryl was the third-most-used insecticide in the United States for home gardens, commercial agriculture, and forestry and rangeland protection. As a veterinary drug, it is known as carbaril (INN). Production Carbaryl is often inexpensively produced by direct reaction of methyl isocyanate with 1-naphthol. :C10H7OH + CH3NCO → C10H7OC(O)NHCH3 Alternatively, 1-naphthol can be treated with excess phosgene to produce 1- naphthylchloroformate, which is then ...

Overwinter
Overwintering is the process by which some organisms pass through or wait out the winter season, or pass through that period of the year when "winter" conditions (cold or sub-zero temperatures, ice, snow, limited food supplies) make normal activity or even survival difficult or near impossible. In some cases "winter" is characterized not necessarily by cold but by dry conditions; passing through such periods could likewise be called overwintering. Hibernation and migration are the two major ways in which overwintering is accomplished. Animals may also go into a state of reduced physiological activity known as torpor. Overwintering occurs in several classes of lifeform. Insects In entomology, overwintering is how an insect passes the winter season. Many insects overwinter as adults, pupae, or eggs. This can be done inside buildings, under tree bark, or beneath fallen leaves or other plant matter on the ground, among other places. All such overwintering sites shield the insect fr ...

Heart Rot
300px, The bracket fungus '' Fistulina hepatica'' is one of many that cause heart rot. In trees, heart rot is a fungal disease that causes the decay of wood at the center of the trunk and branches. Fungi enter the tree through wounds in the bark and decay the heartwood. The diseased heartwood softens, making trees structurally weaker and prone to breakage. Heart rot is a major factor in the economics of logging and the natural growth dynamic of many older forests. Heart rot is prevalent throughout the world affecting all hardwood trees and can be very difficult to prevent. A good indication of heart rot is the presence of mushrooms or fungus conks on the tree. Biological cause Heart rot is caused by fungi entering the trunk of the tree through wounds in the bark. These wounds are areas of the tree where bare wood is exposed and usually, a result of improper pruning, fire damage, dead branches, insects, or even animal damage. The fungal spores enter the exposed wounds, germinate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phellinus Robiniae
''Phellinus robiniae'', commonly called the cracked cap polypore or Phellinus rimosus, is a fungus of the family of Hymenochaetaceae. The fungus primarily infests black locusts, aided by openings caused by '' Megacyllene robiniae'' infestation, but also grows on various other trees such as ''Carya'', oak, and ''Acacia''.

Male And Female Megacyllene Robiniae 321331624
Male (symbol: ♂) is the sex of an organism that produces the gamete (sex cell) known as sperm, which fuses with the larger female gamete, or ovum, in the process of fertilization. A male organism cannot reproduce sexually without access to at least one ovum from a female, but some organisms can reproduce both sexually and asexually. Most male mammals, including male humans, have a Y chromosome, which codes for the production of larger amounts of testosterone to develop male reproductive organs. Not all species share a common sex-determination system. In most animals, including humans, sex is determined genetically; however, species such as ''Cymothoa exigua'' change sex depending on the number of females present in the vicinity. In humans, the word ''male'' can also be used to refer to gender in the social sense of gender role or gender identity. Overview The existence of separate sexes has evolved independently at different times and in different lineages, an example of ...

Meadow
A meadow ( ) is an open habitat, or field, vegetated by grasses, herbs, and other non-woody plants. Trees or shrubs may sparsely populate meadows, as long as these areas maintain an open character. Meadows may be naturally occurring or artificially created from cleared shrub or woodland. They can occur naturally under favourable conditions (see perpetual meadows), but they are often maintained by humans for the production of hay, fodder, or livestock. Meadow habitats, as a group, are characterized as "semi-natural grasslands", meaning that they are largely composed of species native to the region, with only limited human intervention. Meadows attract a multitude of wildlife, and support flora and fauna that could not thrive in other habitats. They are ecologically important as they provide areas for animal courtship displays, nesting, food gathering, pollinating insects, and sometimes sheltering, if the vegetation is high enough. There are multiple types of meadows, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Field (agriculture)
In agriculture, a field is an area of land, enclosed or otherwise, used for agricultural purposes such as cultivating crops or as a paddock or other enclosure for livestock. A field may also be an area left to lie fallow or as arable land. Many farms have a field border, usually composed of a strip of shrubs and vegetation, used to provide food and cover necessary for the survival of wildlife. It has been found that these borders may lead to an increased variety of animals and plants in the area, but also in some cases a decreased yield of crops. Paddock In Australian and New Zealand English, any agricultural field may be called a ''paddock'', especially if for keeping sheep or cattle. If stock are grazed there, the space may be called a ''run'', e.g. ''sheep run''; ''cattle run''. The term paddock is used more specifically in animal husbandry for a system in which grazing land is divided into small areas, paddocks, and the stock graze each paddock in turn for a short peri ...
