C. P. Lounsbury
Charles Pugsley Lounsbury (20 September 1872 Brooklyn - 7 June 1955 Pretoria) was an American-born South African entomologist, widely regarded as having laid the foundations of economic entomology in Southern Africa. Lounsbury spent his childhood in Boston and later studied at the Massachusetts Agricultural College, where after graduation he stayed on as instructor. In 1893 the Department of Agriculture for the Cape Colony grew concerned about the incidence of phylloxera in the vineyards, and asked for recommendations from L. O. Howard, Head of the Division of Entomology of the U.S. Department of Agriculture, who suggested Lounsbury. When the post was offered to Lounsbury in 1895 at an annual salary of £600, he accepted, married Rose Linda Davis (6 September 1872 - July 1920) who was an assistant in Albany to the New York State Entomologist, and set off for Cape Town shortly before his 23rd birthday. As soon as he had settled in, Lounsbury requisitioned a bicycle and typewriter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

East Coast Fever
East Coast fever, also known as theileriosis, is a disease of cattle which occurs in Africa and is caused by the protozoan parasite ''Theileria parva''. The primary vector which spreads ''T. parva'' between cattle is a tick, ''Rhipicephalus appendiculatus''. East Coast fever is of major economic importance to livestock farmers in Africa, killing at least one million cattle each year. The disease occurs in Burundi, Democratic Republic of Congo, Kenya, Malawi, Mozambique, Rwanda, South Sudan, Tanzania, Uganda, Zimbabwe, Zambia. In 2003, East Coast fever was introduced to Comoros by cattle imported from Tanzania. It has been eradicated in South Africa. A more acute form of East Coast fever called corridor disease occurs when buffalo-derived ''T. parva'' is transmitted to cattle. Another form, called January disease, only occurs over the winter months in Zimbabwe due to the tick lifecycle. Native cattle are often resistant to the parasite, but not without symptoms. They are host ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Massachusetts (Massachusett: ''Muhsachuweesut məhswatʃəwiːsət">Massachusett writing systems">məhswatʃəwiːsət'' English: , ), officially the Commonwealth of Massachusetts, is the most populous state in the New England region of the Northeastern United States. It borders on the Atlantic Ocean and Gulf of Maine to the east, Connecticut and Rhode Island to the south, New Hampshire and Vermont to the north, and New York to the west. The state's capital and most populous city, as well as its cultural and financial center, is Boston. Massachusetts is also home to the urban core of Greater Boston, the largest metropolitan area in New England and a region profoundly influential upon American history, academia, and the research economy. Originally dependent on agriculture, fishing, and trade. Massachusetts was transformed into a manufacturing center during the Industrial Revolution. During the 20th century, Massachusetts's economy shifted from manufacturing to services. M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

South African Entomologists
South is one of the cardinal directions or Points of the compass, compass points. The direction is the opposite of north and is perpendicular to both east and west. Etymology The word ''south'' comes from Old English ''sūþ'', from earlier Proto-Germanic language, Proto-Germanic ''*sunþaz'' ("south"), possibly related to the same Proto-Indo-European language, Proto-Indo-European root that the word ''sun'' derived from. Some languages describe south in the same way, from the fact that it is the direction of the sun at noon (in the Northern Hemisphere), like Latin meridies 'noon, south' (from medius 'middle' + dies 'day', cf English meridional), while others describe south as the right-hand side of the rising sun, like Biblical Hebrew תֵּימָן teiman 'south' from יָמִין yamin 'right', Aramaic תַּימנַא taymna from יָמִין yamin 'right' and Syriac ܬܰܝܡܢܳܐ taymna from ܝܰܡܝܺܢܳܐ yamina (hence the name of Yemen, the land to the south/right of the ...

1872 Births
Year 187 ( CLXXXVII) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Quintius and Aelianus (or, less frequently, year 940 ''Ab urbe condita''). The denomination 187 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Integrated Pest Management
Integrated pest management (IPM), also known as integrated pest control (IPC) is a broad-based approach that integrates both chemical and non-chemical practices for economic control of pests. IPM aims to suppress pest populations below the economic injury level (EIL). The UN's Food and Agriculture Organization defines IPM as "the careful consideration of all available pest control techniques and subsequent integration of appropriate measures that discourage the development of pest populations and keep pesticides and other interventions to levels that are economically justified and reduce or minimize risks to human health and the environment. IPM emphasizes the growth of a healthy crop with the least possible disruption to agro-ecosystems and encourages natural pest control mechanisms." Entomologists and ecologists have urged the adoption of IPM pest control since the 1970s. IPM allows for safer pest control. The introduction and spread of invasive species can also be managed ...

Gonipterus Scutellatus
''Gonipterus scutellatus'' is a species of weevil in the family Curculionidae. It is commonly known as the eucalyptus snout beetle, the eucalyptus weevil or the gum tree weevil.

Cochineal
The cochineal ( , ; ''Dactylopius coccus'') is a scale insect in the suborder Sternorrhyncha, from which the natural dye carmine is derived. A primarily sessile parasite native to tropical and subtropical South America through North America (Mexico and the Southwest United States), this insect lives on cacti in the genus ''Opuntia'', feeding on plant moisture and nutrients. The insects are found on the pads of prickly pear cacti, collected by brushing them off the plants, and dried. The insect produces carminic acid that deters predation by other insects. Carminic acid, typically 17–24% of dried insects' weight, can be extracted from the body and eggs, then mixed with aluminium or calcium salts to make carmine dye, also known as cochineal. Today, carmine is primarily used as a colorant in food and in lipstick (E120 or Natural Red 4). Carmine dye was used in the Americas for coloring fabrics and became an important export good in the 16th century during the colon ...

Opuntia Vulgaris
''Opuntia ficus-indica'', the Indian fig opuntia, fig opuntia, or prickly pear, is a species of cactus that has long been a domesticated crop plant grown in agricultural economies throughout arid and semiarid parts of the world. ''O. ficus-indica'' is the most widespread and most commercially important cactus. It is grown primarily as a fruit crop, and also for the vegetable nopales and other uses. Cacti are good crops for dry areas because they efficiently convert water into biomass. ''O. ficus-indica'', as the most widespread of the long-domesticated cactuses, is as economically important as maize and blue agave in Mexico. ''Opuntia'' species hybridize easily, but the wild origin of ''O. ficus-indica'' is likely to have been in central Mexico, where its closest genetic relatives are found. Names Most culinary references to the "prickly pear" refer to this species. The Spanish name ''tuna'' is also used for the fruit of this cactus and for ''Opuntia'' in general; according to A ...
