Maconellicoccus Hirsutus
''Maconellicoccus hirsutus'', (also known as the pink, grape or hibiscus mealybug) is a pest of many plants, trees, and shrubs. It infests hibiscus, citrus, coffee, sugar cane, annonas, plums, guava, mango (although, mango mealybug is more problematic), okra, sorrel, teak, mora, pigeon pea, peanut, grapevine, maize, asparagus, chrysanthemum, beans, cotton, soybean, cocoa, and many other plants. The pest forms colonies on the host plant, and if left undisturbed, the colonies will grow into large masses of white waxy coverings on branches, fruiting structures, leaves, and even whole plants, including large trees. Lifecycle Both female and male adult hibiscus mealybugs are about one-eighth inch (3 mm) long. Female bodies are pink in color with a white waxy covering. They are wingless and appear as ovoid shapes covered by a mass of white mealy wax. Males have a pair of wings and two long waxy tails and are capable of flight. The mature female lays eggs in an egg sack of white wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Ernest Green
Edward Ernest Green (20 February 1861–2 July 1949) was an Ceylon-born English mycologist and entomologist who specialised in the scale-insects, Coccidae. An accomplished artist, and lithographer, he illustrated the five volume ''Coccidae of Ceylon''. Biography Edward was born in Colombo, Sri Lanka to Jane Mary née Akers (d. 1863) and John Philip Green who owned coffee and tea plantations in Ceylon. His paternal grandfather Philip James Green was Consul-General for Ceylon. An uncle, Staniforth Green was a partner of the German planter and entomologist John Nietner and had hosted Ernst Haeckel and corresponded with entomologists like J.O. Westwood. After schooling at Charterhouse, Edward returned to the family plantations at Pundaluoya in 1880 and became familiar with the ravages of ''Hemileia vastatrix'' and '' Coccus viridis'' which were to cause the end of coffee cultivation in Ceylon. He met Harry Marshall Ward who was in Ceylon to study the coffee rust and conducted h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asparagus
Asparagus, or garden asparagus, folk name sparrow grass, scientific name ''Asparagus officinalis'', is a perennial flowering plant species in the genus ''Asparagus''. Its young shoots are used as a spring vegetable. It was once classified in the lily family, like the related ''Allium'' species, onions and garlic. However, genetic research places lilies, ''Allium'', and asparagus in three separate families—the Liliaceae, Amaryllidaceae, and Asparagaceae, respectively— the Amaryllidaceae and Asparagaceae are grouped together in the order Asparagales. Sources differ as to the native range of ''Asparagus officinalis'', but generally include most of Europe and western temperate Asia. It is widely cultivated as a vegetable crop. Description Asparagus is a herbaceous, perennial plant growing to tall, with stout stems with much-branched, feathery foliage. The 'leaves' are in fact needle-like cladodes ( modified stems) in the axils of scale leaves; they are long and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Middle East
The Middle East ( ar, الشرق الأوسط, ISO 233: ) is a geopolitical region commonly encompassing Arabian Peninsula, Arabia (including the Arabian Peninsula and Bahrain), Anatolia, Asia Minor (Asian part of Turkey except Hatay Province), East Thrace (European part of Turkey), Egypt, Iran, the Levant (including Syria (region), Ash-Shām and Cyprus), Mesopotamia (modern-day Iraq), and the Socotra Governorate, Socotra Archipelago (a part of Yemen). The term came into widespread usage as a replacement of the term Near East (as opposed to the Far East) beginning in the early 20th century. The term "Middle East" has led to some confusion over its changing definitions, and has been viewed by some to be discriminatory or too Eurocentrism, Eurocentric. The region includes the vast majority of the territories included in the closely associated definition of Western Asia (including Iran), but without the South Caucasus, and additionally includes all of Egypt (not just the Sina ...

Asia
Asia (, ) is one of the world's most notable geographical regions, which is either considered a continent in its own right or a subcontinent of Eurasia, which shares the continental landmass of Afro-Eurasia with Africa. Asia covers an area of , about 30% of Earth's total land area and 8.7% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Its 4.7 billion people constitute roughly 60% of the world's population. In general terms, Asia is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a historical and cultural construct, as there is no clear physical and geographical separation between them. It is somewhat arbitrary and has moved since its first conception in classical antiquity. The division of Eurasia into two continents reflects East–West cultural, linguistic, ...

Instar
An instar (, from the Latin '' īnstar'', "form", "likeness") is a developmental stage of arthropods, such as insects, between each moult (''ecdysis''), until sexual maturity is reached. Arthropods must shed the exoskeleton in order to grow or assume a new form. Differences between instars can often be seen in altered body proportions, colors, patterns, changes in the number of body segments or head width. After shedding their exoskeleton (moulting), the juvenile arthropods continue in their life cycle until they either pupate or moult again. The instar period of growth is fixed; however, in some insects, like the salvinia stem-borer moth, the number of instars depends on early larval nutrition. Some arthropods can continue to moult after sexual maturity, but the stages between these subsequent moults are generally not called instars. For most insect species, an ''instar'' is the developmental stage of the larval forms of holometabolous (complete metamorphism) or nymphal forms o ...

Parthenogenesis
Parthenogenesis (; from the Greek grc, παρθένος, translit=parthénos, lit=virgin, label=none + grc, γένεσις, translit=génesis, lit=creation, label=none) is a natural form of asexual reproduction in which growth and development of embryos occur in a gamete (egg or sperm) without combining with another gamete (e.g., egg and sperm fusing). In animals, parthenogenesis means development of an embryo from an unfertilized Gametophyte, egg cell. In plants, parthenogenesis is a component process of apomixis. In algae, parthenogenesis can mean the development of an embryo from either an individual sperm or an individual egg. Parthenogenesis occurs naturally in some plants, algae, invertebrate animal species (including nematodes, some tardigrades, water fleas, some scorpions, aphids, some mites, some bees, some Phasmatodea and parasitic wasps) and a few vertebrates (such as some fish, amphibians, reptiles and birds). This type of reproduction has been induced artificially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cocoa Bean
The cocoa bean (technically cocoa seed) or simply cocoa (), also called the cacao bean (technically cacao seed) or cacao (), is the dried and fully fermented seed of ''Theobroma cacao'', from which cocoa solids (a mixture of nonfat substances) and cocoa butter (the fat) can be extracted. Cocoa beans are the basis of chocolate, and Mesoamerican foods including tejate, an indigenous Mexican drink that also includes maize, and pinolillo, a similar Nicaraguan drink made from a cornmeal & cocoa powder. Etymology The word ''cocoa'' comes from the Spanish word , which is derived from the Nahuatl word . The Nahuatl word, in turn, ultimately derives from the reconstructed Proto-Mixe–Zoquean word ''kakawa''. Used on its own, the term ''cocoa'' may also mean: * Hot cocoa, the drink more known as ''hot chocolate'' Terms derived from ''cocoa'' include: * Cocoa paste, ground cocoa beans: the mass is melted and separated into: ** Cocoa butter, a pale, yellow, edible fat ** Cocoa s ...

Soybean
The soybean, soy bean, or soya bean (''Glycine max'') is a species of legume native to East Asia, widely grown for its edible bean, which has numerous uses. Traditional unfermented food uses of soybeans include soy milk, from which tofu and tofu skin are made. Fermented soy foods include soy sauce, fermented bean paste, nattō, and tempeh. Fat-free (defatted) soybean meal is a significant and cheap source of protein for animal feeds and many packaged meals. For example, soybean products, such as textured vegetable protein (TVP), are ingredients in many meat and dairy substitutes. Soybeans contain significant amounts of phytic acid, dietary minerals and B vitamins. Soy vegetable oil, used in food and industrial applications, is another product of processing the soybean crop. Soybean is the most important protein source for feed farm animals (that in turn yields animal protein for human consumption). Etymology The word "soy" originated as a corruption of the Cantonese or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
