Icerya Purchasi
''Icerya purchasi'' ( common name: cottony cushion scale) is a scale insect that feeds on more than 80 families of woody plants, most notably on ''Citrus'' and ''Pittosporum''. Originally described in 1878 from specimens collected in New Zealand as pests of kangaroo acacia and named by W.M. Maskell "after the Rev. Dr. Purchas who, ebelieve first found it". It is now found worldwide where citrus crops are grown. The cottony cushion scale originates from Australia. Life cycle This scale infests twigs and branches. The mature hermaphrodite is oval in shape, reddish-brown with black hairs, 5 mm long. When mature, the insect remains stationary, attaches itself to the plant by waxy secretions, and produces a white egg sac in grooves, by extrusion, in the body which encases hundreds of red eggs. The egg sac will grow to be two to three times as long as the body. Newly hatched nymphs are the primary dispersal stage, with dispersion known to occur by wind and by crawling. Earl ...

William Miles Maskell
William Miles Maskell (5 October 1839 – 1 May 1898) was a New Zealand farmer, politician and entomologist. Early life Born in Mapperton, Dorset, England to Mary Scott and William Maskell, an Anglican clergyman, he attended school at St Mary's College in Oscott, Birmingham, and later in Paris, before being commissioned an ensign in the 11th Regiment of Foot with which he served for just under two years. He first came to New Zealand to Lyttelton, in 1860 aboard . He eventually became involved in the political campaigns of Frederick Weld and Charles Clifford. He returned to England sometime between 1861 and 1863, but returned by September 1865, purchasing a property in Broadleaze near Leithfield, Canterbury a short while after. He became registrar of the newly formed University of New Zealand in 1876 and held this position until his death. Maskell was married to Lydia Cooper Brown on 15 September 1874 in two ceremonies, one Catholic and one Protestant. After Lydia's de ...

Rodolia Cardinalis USDA
''Novius'' is a genus of ladybird beetles belonging to the family Coccinellidae, and the sole member of the tribe Noviini. The genus as presently defined contains over 70 species, most of which were formerly placed in the genera ''Rodolia'' and ''Anovia'', but after decades of debate, both of these genera are now considered to be junior synonyms of ''Novius''.Pang, H., Tang, X.-F., Booth, R.G., Vandenberg, N., Forrester, J., Mchugh, J., & Ślipiński, A.

Insects Described In 1878
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] |
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] |
Citrus Pests
''Citrus'' is a genus of flowering trees and shrubs in the rue family, Rutaceae. Plants in the genus produce citrus fruits, including important crops such as oranges, lemons, grapefruits, pomelos, and limes. The genus ''Citrus'' is native to South Asia, East Asia, Southeast Asia, Melanesia, and Australia. Various citrus species have been used and domesticated by indigenous cultures in these areas since ancient times. From there its cultivation spread into Micronesia and Polynesia by the Austronesian expansion (c. 3000–1500 BCE); and to the Middle East and the Mediterranean (c. 1200 BCE) via the incense trade route, and onwards to Europe and the Americas. History Citrus plants are native to subtropical and tropical regions of Asia, Island Southeast Asia, Near Oceania, and northeastern Australia. Domestication of citrus species involved much hybridization and introgression, leaving much uncertainty about when and where domestication first happened. A genomic, phylogenic, ...

Agricultural Research
Agricultural science (or agriscience for short) is a broad multidisciplinary field of biology that encompasses the parts of exact, natural, economic and social sciences that are used in the practice and understanding of agriculture. Professionals of the agricultural science are called agricultural scientists or agriculturists. History In the 18th century, Johann Friedrich Mayer conducted experiments on the use of gypsum (hydrated calcium sulphate) as a fertilizer.John Armstrong, Jesse Buel. ''A Treatise on Agriculture, The Present Condition of the Art Abroad and at Home, and the Theory and Practice of Husbandry. To which is Added, a Dissertation on the Kitchen and Garden.'' 1840. p. 45. In 1843, John Bennet Lawes and Joseph Henry Gilbert began a set of long-term field experiments at Rothamsted Research in England, some of which are still running as of 2018. In the United States, a scientific revolution in agriculture began with the Hatch Act of 1887, which used the term " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imidacloprid
Imidacloprid is a systemic insecticide belonging to a class of chemicals called the neonicotinoids which act on the central nervous system of insects. The chemical works by interfering with the transmission of stimuli in the insect nervous system. Specifically, it causes a blockage of the nicotinergic neuronal pathway. By blocking nicotinic acetylcholine receptors, imidacloprid prevents acetylcholine from transmitting impulses between nerves, resulting in the insect's paralysis and eventual death. It is effective on contact and via stomach action. Because imidacloprid binds much more strongly to insect neuron receptors than to mammal neuron receptors, this insecticide is more toxic to insects than to mammals. From 1999 through , imidacloprid was the most widely used insecticide in the world. Although it is now off patent, the primary manufacturer of this chemical is Bayer CropScience (part of Bayer AG). It is sold under many names for many uses; it can be applied by soil injection ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Charles Valentine Riley
Charles Valentine Riley (18 September 1843 – 14 September 1895) was a British-born American entomologist and artist. He was one of the first individuals to use biological pest control and authored over 2,400 publications. He convinced Congress to create the United States Entomological Commission and was among the founders of the American Association of Economic Entomologists. Early life The son of a Church of England minister, Charles Valentine Riley was born on 19 September 1843 in London's Chelsea district. When he was around eleven his parents, the Rev. Charles and Mary (née Valentine) Riley, chose to further his education in Europe. There he excelled at art and natural history attending private schools in Dieppe, France and later Bonn, Germany. After the death of his father he was brought home to Britain to enroll in a public school there.
