Nysius Raphanus
''Nysius raphanus'' (also known as the false chinch bug) is a small (no more than inch) North American insect in the order Hemiptera and family Lygaeidae. They are grey to brown in color, with largely transparent wings, and can release an offensive odor similar to stinkbugs. They have no larval stage, instead going through several nymph stages with the nymphs resembling adults but having no wings. In high numbers false chinch bugs can cause significant plant damage.

John Eliot Howard
John Eliot Howard (11 December 1807 – 22 November 1883) was an English chemist of the nineteenth century, who conducted pioneering work with the development of quinine. Howard was born in Plaistow, Essex, the son of Luke Howard a noted Quaker meteorologist and chemist. He worked at the family pharmaceutical manufacturing business of Howards and Sons. He was elected a Fellow of the Royal Society in June 1874. He was the author of scientific works including ''The Quinology of the East Indian Plantations (1869–1876)'', religious works including a commentary on the book of Hebrews and histories including ''The Island Of The Saints'', about the Reformation in Ireland. Howard was originally a Quaker, but became connected with Christians meeting at the new Brooks Street Meeting House in Tottenham, now Brook Street Chapel, which was founded in 1838–1839 by a number of other Christians including Howard's brother Robert; his father Luke (the 'namer of clouds') helped to finance t ...

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hemiptera
Hemiptera (; ) is an order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, assassin bugs, bed bugs, and shield bugs. They range in size from to around , and share a common arrangement of piercing-sucking mouthparts. The name "true bugs" is often limited to the suborder Heteroptera. Entomologists reserve the term ''bug'' for Hemiptera or Heteroptera,Gilbert Waldbauer. ''The Handy Bug Answer Book.'' Visible Ink, 1998p. 1. which does not include other arthropods or insects of other orders such as ants, bees, beetles, or butterflies. In some variations of English, all terrestrial arthropods (including non-insect arachnids, and myriapods) also fall under the colloquial understanding of ''bug''. Many insects with "bug" in their common name, especially in American English, belong to other orders; for example, the lovebug is a fly and the Maybug and ladybug are beetles. The term ...

Lygaeidae
The Lygaeidae are a family in the Hemiptera (true bugs), with more than 110 genera in four subfamilies. The family is commonly referred to as seed bugs, and less commonly, milkweed bugs, or ground bugs. However, while many of the species feed on seeds, some feed on sap ( mucivory) or seed pods, others are omnivores and a few, such as the wekiu bug, are carnivores that feed exclusively on insects. Insects in this family are distributed across the world, including throughout North America. The family was vastly larger, but numerous former subfamilies have been removed and given independent family status, including the Artheneidae, Blissidae, Cryptorhamphidae, Cymidae, Geocoridae, Heterogastridae, Ninidae, Oxycarenidae and Rhyparochromidae, which together constituted well over half of the former family. The bizarre and mysterious beetle-like Psamminae were formerly often placed in the Piesmatidae, but this is almost certainly incorrect. Their true affiliations, however, a ...

Halyomorpha Halys
The brown marmorated stink bug (''Halyomorpha halys'') is an insect in the family Pentatomidae, native to China, Japan, Korea and other Asian regions. In September 1998 it was collected in Allentown, Pennsylvania, where it is believed to have been accidentally introduced. The nymphs and adults of the brown marmorated stink bug feed on over 100 species of plants, including many agricultural crops, and by 2010–11 had become a season-long pest in orchards in the Eastern United States. In 2010, in the Mid-Atlantic United States, $37 million in apple crops were lost, and some stone fruit growers lost more than 90% of their crops. Since the 2010's the bug has spread to Georgia and Turkey and caused extensive damage to hazelnut production. It is now established in many parts of North America, and has recently become established in Europe and South America. Description Adult brown marmorated stink bugs are approximately long and about as wide, forming the heraldic shield shape char ...

Nymph
A nymph ( grc, νύμφη, nýmphē, el, script=Latn, nímfi, label=Modern Greek; , ) in ancient Greek folklore is a minor female nature deity. Different from Greek goddesses, nymphs are generally regarded as personifications of nature, are typically tied to a specific place or landform, and are usually depicted as maidens. They were not necessarily immortal, but lived much longer than human beings. They are often divided into various broad subgroups, such as the Meliae (ash tree nymphs), the Dryads (oak tree nymphs), the Naiads (freshwater nymphs), the Nereids (sea nymphs), and the Oreads (mountain nymphs). Nymphs are often featured in classic works of art, literature, mythology, and fiction. Since the Middle Ages, nymphs have been sometimes popularly associated or even confused with fairies. Etymology The Greek word has the primary meaning of "young woman; bride, young wife" but is not usually associated with deities in particular. Yet the etymology of the noun rem ...

Nysius
''Nysius'' is a genus of false chinch bugs in the family Lygaeidae. At least 100 described species are placed in ''Nysius''. Like other seed bugs, some species in the genus have proven to be crop pests of wheat and other grains (including ''N. huttoni''), as well as many vegetables. A unique Hawaiian radiation of the genus contains almost a quarter of the world's species (26), as well as the most diverse character set seen in the genus. In addition, two closely related species (colloquially known as wēkiu bugs) found on Mauna Loa and Mauna Kea on the island of Hawai'i, are different from the rest of ''Nysius'' by exhibiting reduced nonfunctional wings, and feed on dead and dying insects ('' N. wekiuicola'', '' N. aa'' ). Species The genus contains the following species: * '' Nysius aa'' Polhemus, 1998 * '' Nysius abnormis'' Usinger, 1942 * ''Nysius albipennis'' Distant, W.L., 1913 * '' Nysius angustatus'' Uhler, 1872 * '' Nysius angustellus'' (Blanchard, 1852) * ''Nysius a ...
