Carl Johan Schönherr
Carl Johan Schönherr (10 June 1772 – 28 March 1848) was a Swedish entomologist who revised the taxonomy of beetles, including weevils. Born in Stockholm, Schönherr was son of a German immigrant who had established himself as a silk manufacturer. At the age of nineteen, he took over the business together with his mother and developed it into a considerable size, with about 200 workers. In 1805, he entered partnership with Erik Lundgren, and in 1811 he sold the business to him, while retiring to his manor Sparresäter in Lerdala outside Skara in Västergötland, where he died in 1848. Schönherr had taken an interest in entomology since the age of twelve and was later further stimulated through his friendship with Gustaf Johan Billberg, his brother-in-law from his second marriage.Bengt Ehnström, "Schönherr, Carl Johan", ''Svenskt biografiskt lexikon'', vol. 31, p. 755. He was an eminent coleopterist co-operating with Carl Henrik Boheman and Leonard Gyllenhaal. Schönherr w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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.

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] |
Hickory
Hickory is a common name for trees composing the genus ''Carya'', which includes around 18 species. Five or six species are native to China, Indochina, and India (Assam), as many as twelve are native to the United States, four are found in Mexico, and two to four are native to Canada. A number of hickory species are used for products like edible nuts or wood. Hickories are temperate forest trees with pinnately compound leaves and large nuts. Hickory flowers are small, yellow-green catkins produced in spring. They are wind-pollinated and self-incompatible. The fruit is a globose or oval nut, long and diameter, enclosed in a four-valved husk, which splits open at maturity. The nut shell is thick and bony in most species, and thin in a few, notably the pecan (''C. illinoinensis''); it is divided into two halves, which split apart when the seed germinates. Etymology The name "hickory" derives from a Native American word in an Algonquian language (perhaps Powhatan). It is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phylloxera
Grape phylloxera is an insect pest of commercial grapevines worldwide, originally native to eastern North America. Grape phylloxera (''Daktulosphaira vitifoliae'' (Fitch 1855) belong to the family Phylloxeridae, within the order Hemiptera, bugs); originally described in France as ''Phylloxera vastatrix''; equated to the previously described ''Daktulosphaera vitifoliae'', ''Phylloxera vitifoliae''. The insect is commonly just called phylloxera (; from grc, φύλλον, leaf, and , dry). These almost microscopic, pale yellow sap-sucking insects, related to aphids, feed on the roots and leaves of grapevines (depending on the phylloxera genetic strain). On ''Vitis vinifera'', the resulting deformations on roots ("nodosities" and "tuberosities") and secondary fungal infections can girdle roots, gradually cutting off the flow of nutrients and water to the vine.Wine & Spirits Education Trust ''"Wine and Spirits: Understanding Wine Quality"'' pgs 2-5, Second Revised Edition (2012), Lo ...

Pecan
The pecan (''Carya illinoinensis'') is a species of hickory native to the southern United States and northern Mexico in the region of the Mississippi River. The tree is cultivated for its seed in the southern United States, primarily in Georgia, New Mexico, Texas, and Mexico, which produces nearly half of the world total. The seed is an edible nut used as a snack and in various recipes, such as praline candy and pecan pie. The pecan is the state nut of Alabama, Arkansas, California, and Texas and is also the state tree of Texas. Name "Pecan" is from an Algonquin word, variously referring to pecans, walnuts, and hickory nuts. There are many pronunciations, some regional and others not.See "Pecan" at Wiktionary. The most common American pronunciation is . There is little agreement in the United States regarding the "correct" pronunciation, even regionally. Growth The pecan tree is a large deciduous tree, growing to in height, rarely to .Flora of North America''Carya illinoi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

These genera, among others, belong to the subfamily Molytinae: * '' Adexius'' * '' Alloplinthus'' * ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beetles Described In 1837
Beetles are insects that form the Taxonomic rank, order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, Elytron, 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 fungus, 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.
