Biological Pest Control
Biological control or biocontrol is a method of controlling pests, such as insects, mites, weeds, and plant diseases, using other organisms. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role. It can be an important component of integrated pest management (IPM) programs. There are three basic strategies for biological pest control: classical (importation), where a natural enemy of a pest is introduced in the hope of achieving control; inductive (augmentation), in which a large population of natural enemies are administered for quick pest control; and inoculative (conservation), in which measures are taken to maintain natural enemies through regular reestablishment. Natural enemies of insect pests, also known as biological control agents, include predators, parasitoids, pathogens, and competitors. Biological control agents of plant diseases are most often referred to as antagonists. Biolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Biodiversity
Biodiversity or biological diversity is the variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic (''genetic variability''), species (''species diversity''), and ecosystem (''ecosystem diversity'') level. Biodiversity is not distributed evenly on Earth; it is usually greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator. Tropical forest ecosystems cover less than 10% of earth's surface and contain about 90% of the world's species. Marine biodiversity is usually higher along coasts in the Western Pacific, where sea surface temperature is highest, and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots, and has been increasing through time, but will be likely to slow in the future as a primary result of deforestation. It encompasses the evolutionary, ecological, and cultural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cotesia Glomerata
''Cotesia glomerata'', the white butterfly parasite, is a small parasitoid wasp species belonging to family Braconidae. It was first described by Carl Linnaeus in his 1758 publication 10th edition of Systema Naturae. Description The adults of ''Cotesia glomerata'' can reach a length of . This small braconid wasp is black, with two pairs of wings. It can parasitize a wide range of ''Pieris'' butterfly species as host, but the large white (''Pieris brassicae'') and small white (''Pieris rapae'') are the main hosts. The adults feed on nectar. Life cycle After hatching from the pupae, females mate almost immediately and begin laying eggs.Cornell University College of Agricultural and Life ScienceCotesia (=Apanteles) glomerata (Hymenoptera: Braconidae) The eggs are laid in the larvae of butterflies known as caterpillars, where the ''C. glomerata'' larvae develop; multiple eggs numbering between 16–52 are deposited in each caterpillar.

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) ...

Ming Dynasty
The Ming dynasty (), officially the Great Ming, was an imperial dynasty of China, ruling from 1368 to 1644 following the collapse of the Mongol-led Yuan dynasty. The Ming dynasty was the last orthodox dynasty of China ruled by the Han people, the majority ethnic group in China. Although the primary capital of Beijing fell in 1644 to a rebellion led by Li Zicheng (who established the short-lived Shun dynasty), numerous rump regimes ruled by remnants of the Ming imperial family—collectively called the Southern Ming—survived until 1662. The Ming dynasty's founder, the Hongwu Emperor (r. 1368–1398), attempted to create a society of self-sufficient rural communities ordered in a rigid, immobile system that would guarantee and support a permanent class of soldiers for his dynasty: the empire's standing army exceeded one million troops and the navy's dockyards in Nanjing were the largest in the world. He also took great care breaking the power of the court eunuchs and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Song Dynasty
The Song dynasty (; ; 960–1279) was an imperial dynasty of China that began in 960 and lasted until 1279. The dynasty was founded by Emperor Taizu of Song following his usurpation of the throne of the Later Zhou. The Song conquered the rest of the Ten Kingdoms, ending the Five Dynasties and Ten Kingdoms period. The Song often came into conflict with the contemporaneous Liao, Western Xia and Jin dynasties in northern China. After retreating to southern China, the Song was eventually conquered by the Mongol-led Yuan dynasty. The dynasty is divided into two periods: Northern Song and Southern Song. During the Northern Song (; 960–1127), the capital was in the northern city of Bianjing (now Kaifeng) and the dynasty controlled most of what is now Eastern China. The Southern Song (; 1127–1279) refers to the period after the Song lost control of its northern half to the Jurchen-led Jin dynasty in the Jin–Song Wars. At that time, the Song court retreated south of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Five Dynasties
The Five Dynasties and Ten Kingdoms period (), from 907 to 979, was an era of political upheaval and division in 10th-century History of China#Imperial China, Imperial China. Five Dynasties in Chinese history, dynastic states quickly succeeded one another in the Zhongyuan, Central Plain, and more than a dozen concurrent dynastic states were established elsewhere, mainly in South China. It was a prolonged period of multiple political divisions in Chinese imperial history. Traditionally, the era is seen as beginning with the fall of the Tang dynasty in 907 and reaching its climax with the founding of the Song dynasty in 960. In the following 19 years, Song gradually subdued the remaining states in South China, but the Liao dynasty still remained in China's north (eventually succeeded by the Jin dynasty (1115–1234), Jin dynasty), and the Western Xia was eventually established in China's northwest. Many states had been ''de facto'' independent long before 907 as the Tang dynasty' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tang Dynasty
The Tang dynasty (, ; zh, t= ), or Tang Empire, was an imperial dynasty of China that ruled from 618 to 907 AD, with an interregnum between 690 and 705. It was preceded by the Sui dynasty and followed by the Five Dynasties and Ten Kingdoms period. Historians generally regard the Tang as a high point in Chinese civilization, and a golden age of cosmopolitan culture. Tang territory, acquired through the military campaigns of its early rulers, rivaled that of the Han dynasty. The Lǐ family () founded the dynasty, seizing power during the decline and collapse of the Sui Empire and inaugurating a period of progress and stability in the first half of the dynasty's rule. The dynasty was formally interrupted during 690–705 when Empress Wu Zetian seized the throne, proclaiming the Wu Zhou dynasty and becoming the only legitimate Chinese empress regnant. The devastating An Lushan Rebellion (755–763) shook the nation and led to the decline of central authority in the dynasty' ...

Jiaozhi
Jiaozhi (standard Chinese, pinyin: ''Jiāozhǐ''), or Giao Chỉ (Vietnamese), was a historical region ruled by various Chinese dynasties, corresponding to present-day northern Vietnam. The kingdom of Nanyue (204–111 BC) set up the Jiaozhi Commandery (; Vietnamese: Quận Giao Chỉ, Hán-Nôm: 郡交趾) an administrative division centered in the Red River Delta that existed through Vietnam's first and second periods of Chinese rule. During the Han dynasty, the commandery was part of a province of the same name (later renamed to Jiaozhou) that covered modern-day northern and central Vietnam as well as Guangdong and Guangxi in southern China. In 670 AD, Jiaozhi was absorbed into the Annan Protectorate established by the Tang dynasty. Afterwards, official use of the name Jiaozhi was superseded by "Annan" (Annam) and other names of Vietnam, except during the brief fourth period of Chinese rule when the Ming dynasty administered Vietnam as the Jiaozhi Province.
