Robert Newstead
Robert Newstead (11 September 1859 – 17 February 1947) was a British entomologist, naturalist, and archaeologist. He taught himself entomology, wrote a monograph on the scale insects and later served as a professor of medical entomology at the Liverpool School of Tropical Medicine. Newstead was born in Swanton Abbott, Norfolk where his father worked as a butler to Boulton of Oulton Hall. His father later became a gardener at Sedgeford and young Newstead was introduced early to the world of plants and natural history. Newstead went to school but quit at the age of ten to work as a gardener, followed by work in a press, and as a telegraphist. He returned to gardening in 1883 for Osten Walker, an amateur naturalist. Walker paid for his studies and encouraged him to work at the newly founded Grosvenor Museum, Chester. He also encouraged Newstead to study the scale insects which built his repute as an entomologist. He was then given a grant to collect Coccidae from around Britain. For ...

Asterolecaniidae
Asterolecaniidae is a family of scale insects commonly known as pit scales or asterolecaniids. They typically cause a depression in the host plant's tissues and often cause distortion of the shoots. They are found on a range of hosts but are especially common on oaks, bamboos and a number of ornamental plants. Members of this family occur in most regions of the world but are most abundant in the northern hemisphere.UDSA Agricultural Research Service There are about 25 and 243 recorded .

Coffea
''Coffea'' is a genus of flowering plants in the Family (biology), family Rubiaceae. ''Coffea'' species are shrubs or small trees native to tropical and southern Africa and tropical Asia. The seeds of some species, called coffee beans, are used to flavor various beverages and products. The fruits, like the seeds, contain a large amount of caffeine, and have a distinct sweet taste and are often juiced. The plant ranks as one of the world's most valuable and widely traded commodity crops and is an important export product of several countries, including those in Central and South America, the Caribbean and Africa. Cultivation and use There are over 120 species of ''Coffea'', which is grown from seed. The two most popular are ''Coffea arabica'' (commonly known simply as "Arabica"), which accounts for 60–80% of the world's coffee production, and ''Coffea canephora'' (known as "Robusta coffee, Robusta"), which accounts for about 20–40%. '' C. arabica'' is preferred for its s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coffea Arabica
''Coffea arabica'' (), also known as the Arabic coffee, is a species of flowering plant in the coffee and madder family Rubiaceae. It is believed to be the first species of coffee to have been cultivated and is currently the dominant cultivar, representing about 60% of global production. Coffee produced from the less acidic, more bitter, and more highly caffeinated robusta bean ('' C. canephora'') makes up most of the remaining coffee production. Arabica coffee originates from and was first cultivated in Yemen, and documented by the 12th century. ''Coffea arabica'' is called () in Arabic, borrowed from the Amharic "Buna". Taxonomy ''Coffea arabica'' was first described scientifically by Antoine de Jussieu, who named it ''Jasminum arabicum'' after studying a specimen from the Botanic Gardens of Amsterdam. Linnaeus placed it in its own genus ''Coffea'' in 1737. ''Coffea arabica'' is the only polyploid species of the genus ''Coffea,'' as it carries 4 copies of the 11 chromosom ...

Photinia Japonica
The loquat (''Eriobotrya japonica'') is a large evergreen shrub or tree, grown commercially for its orange fruit and for its leaves, which are used to make herbal tea. It is also cultivated as an ornamental plant. The loquat is in the family Rosaceae, and is native to the cooler hill regions of south-central China.

Agricultural Pest Insects
A pest is any animal or plant harmful to humans or human concerns. The term is particularly used for creatures that damage crops, livestock, and forestry or cause a nuisance to people, especially in their homes. Humans have modified the environment for their own purposes and are intolerant of other creatures occupying the same space when their activities impact adversely on human objectives. Thus, an elephant is unobjectionable in its natural habitat but a pest when it tramples crops. Some animals are disliked because they bite or sting; snakes, wasps, ants, bed bugs, fleas and ticks belong in this category. Others enter the home; these include houseflies, which land on and contaminate food, beetles, which tunnel into the woodwork, and other animals that scuttle about on the floor at night, like cockroaches, which are often associated with unsanitary conditions. Agricultural and horticultural crops are attacked by a wide variety of pests, the most important being insects, mite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
