Thrips
Thrips ( order Thysanoptera) are minute (mostly long or less), slender insects with fringed wings and unique asymmetrical mouthparts. Different thrips species feed mostly on plants by puncturing and sucking up the contents, although a few are predators. Entomologists have described approximately 6,000 species. They fly only weakly and their feathery wings are unsuitable for conventional flight; instead, thrips exploit an unusual mechanism, clap and fling, to create lift using an unsteady circulation pattern with transient vortices near the wings. Many thrips species are pests of commercially important crops. A few species serve as vectors for over 20 viruses that cause plant disease, especially the Tospoviruses. Some species of thrips are beneficial as pollinators or as predators of other insects or mites. In the right conditions, such as in greenhouses, many species can exponentially increase in population size and form large swarms because of a lack of natural predators ...

Millet
Millets () are a highly varied group of small-seeded grasses, widely grown around the world as cereal crops or grains for fodder and human food. Most species generally referred to as millets belong to the tribe Paniceae, but some millets also belong to various other taxa. Millets are important crops in the semiarid tropics of Asia and Africa (especially in India, Mali, Nigeria, and Niger), with 97% of millet production in developing countries. This crop is favored due to its productivity and short growing season under dry, high-temperature conditions. Millets are indigenous to many parts of the world. The most widely grown millets are sorghum and pearl millets, which are important crops in India and parts of Africa. Finger millet, proso millet, and foxtail millet are also important crop species. Millets may have been consumed by humans for about 7,000 years and potentially had "a pivotal role in the rise of multi-crop agriculture and settled farming societies." Descript ...

Sorghum
''Sorghum'' () is a genus of about 25 species of flowering plants in the grass family (Poaceae). Some of these species are grown as cereals for human consumption and some in pastures for animals. One species is grown for grain, while many others are used as fodder plants, either cultivated in warm climates worldwide or naturalized in pasture lands. Taxonomy ''Sorghum'' is in the Poaceae (grass) subfamily Panicoideae and the tribe Andropogoneae (the same as maize, big bluestem and sugarcane). Species Accepted species recorded include: Distribution and habitat Seventeen of the 25 species are native to Australia, with the range of some extending to Africa, Asia, Mesoamerica, and certain islands in the Indian and Pacific Oceans. Toxicity In the early stages of the plants' growth, some species of sorghum can contain levels of hydrogen cyanide, hordenine, and nitrates, which are lethal to grazing animals. Plants stressed by drought or heat can also contain toxic lev ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Finger Millet
''Eleusine coracana'', or finger millet, also known as ragi in India, kodo in Nepal, is an annual herbaceous plant widely grown as a cereal crop in the arid and semiarid areas in Africa and Asia. It is a tetraploid and self-pollinating species probably evolved from its wild relative ''Eleusine africana''. Finger millet is native to the Ethiopian and Ugandan highlands. Interesting crop characteristics of finger millet are the ability to withstand cultivation at altitudes over 2000 m above sea level, its high drought tolerance, and the long storage time of the grains. History Finger millet originated in East Africa (Ethiopian and Ugandan highlands). It was claimed to have been found in an Indian archaeological site dated to 1800 BCE (Late Bronze Age); however, this was subsequently demonstrated to be incorrectly identified cleaned grains of hulled millets. The oldest record of finger millet comes from an archaeological site in Africa dating to the 8th century AD. By 1996, culti ...

Pearl Millet
Pearl millet (''Cenchrus americanus'', commonly known as the synonym ''Pennisetum glaucum''; also known as 'Bajra' in Hindi, 'Sajje' in Kannada, 'Kambu' in Tamil, 'Bajeer' in Kumaoni and 'Maiwa' in Hausa, 'Mexoeira' in Mozambique) is the most widely grown type of millet. It has been grown in Africa and the Indian subcontinent since prehistoric times. The center of diversity, and suggested area of domestication, for the crop is in the Sahel zone of West Africa. Recent archaeobotanical research has confirmed the presence of domesticated pearl millet on the Sahel zone of northern Mali between 2500 and 2000 BC. Description Pearl millet has ovoid grains of 3 – 4 mm length, the largest kernels of all varieties of millet (not including sorghum). These can be nearly white, pale yellow, brown, grey, slate blue or purple. The 1000-seed weight can be anything from 2.5 to 14 g with a mean of 8 g. The height of the plant ranges from 0.5 – 4 m. Cultivation Pearl millet is well ad ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Foxtail Millet
Foxtail millet, scientific name ''Setaria italica'' (synonym ''Panicum italicum'' L.), is an annual grass grown for human food. It is the second-most widely planted species of millet, and the most grown millet species in Asia. The oldest evidence of foxtail millet cultivation was found along the ancient course of the Yellow River in Cishan, China, carbon dated to be from around 8,000 years before present. Foxtail millet has also been grown in India since antiquity. Other names for the species include dwarf setaria, foxtail bristle-grass, giant setaria, green foxtail, Italian millet, German millet, and Hungarian millet. Description Foxtail millet is an annual grass with slim, vertical, leafy stems which can reach a height of . The seedhead is a dense, hairy panicle long. The small seeds, around in diameter, are encased in a thin, papery hull which is easily removed in threshing. Seed color varies greatly between varieties.

Phlaeothripidae
Phlaeothripidae is a family of thrips with hundreds of genera. They are the only extant family of the suborder Tubulifera, alongside the extinct family Rohrthripidae and are themselves ordered into two subfamilies, the Idolothripinae with 80 genera, and the Phlaeothripinae with almost 400. Some 3,400 species are recognised in this family, and many are fungivores living in the tropics.Moritz, G., D. Morris, and L. Mound. 2001. ThripsID: pest thrips of the world. ACIAR and CSIRO Publishing, Collingwood. Thrips from this family are fairly common, and are generally larger than those in the suborder Terebrantia (containing all other thrips). '' Idolothrips marginatus'' can attain a body length of up to 14 mm. The group is distinguished by having the last abdominal segment modified into a tube-like structure – hence the suborder's name, which means "tube-bearers". Selected species Some of the better-known species are: * '' Aleurothrips fasciapennis'' (Franklin) - feeds o ...
