Xylosandrus Compactus
''Xylosandrus compactus'' is a species of ambrosia beetle. Common names for this beetle include black twig borer, black coffee borer, black coffee twig borer and tea stem borer. The adult beetle is dark brown or black and inconspicuous; it bores into a twig of a host plant and lays its eggs, and the larvae create further tunnels through the plant tissues. These beetles are agricultural pests that damage the shoots of such crops as coffee, tea, Theobroma cacao, cocoa and avocado. Description This beetle is dark brown or black. The adult female is up to long and about half as wide. The head is convex at the front with an indistinct transverse groove above the mouthparts. Each Antenna (biology), antenna consists of a funicle (base) with five segments and an obliquely truncated club slightly longer than it is wide. The pronotum is rounded with six or eight serrations on the front edge. The Elytron, elytra are convex and grooved and have fine perforations, and there are bristles betwe ...

Flueggea Neowawraea
''Flueggea neowawraea'', the mēhamehame, is a species of Flowering plant, flowering tree in the family (biology), family Phyllanthaceae, that is Endemism, endemic to Hawaii. It can be found in Hawaiian tropical dry forests, dry, Hawaiian tropical rainforests#Coastal mesic forests, coastal mesic, and Hawaiian tropical rainforests#Mixed mesic forests, mixed mesic forests at elevations of . Associated plants include kukui (''Aleurites moluccanus''), hame (''Antidesma pulvinatum''), ahakea (''Bobea'' sp.), alahee (''Psydrax odorata''), olopua (''Nestegis sandwicensis''), hao (''Rauvolfia sandwicensis''), and aiai (''Streblus pendulinus''). Mēhamehame was one of the largest trees in Hawaii, reaching a height of and trunk diameter of . Native Hawaiians used the extremely hard wood of this tree to make weaponry. Although it had declined along with other dry and mesic forest plants, many large trees could still be found until the 1970s. At that point, the arrival of the black tw ...

Elateridae
Elateridae or click beetles (or "typical click beetles" to distinguish them from the related families Cerophytidae and Eucnemidae, which are also capable of clicking) are a family of beetles. Other names include elaters, snapping beetles, spring beetles or skipjacks. This family was defined by William Elford Leach (1790–1836) in 1815. They are a cosmopolitan beetle family characterized by the unusual click mechanism they possess. There are a few other families of Elateroidea in which a few members have the same mechanism, but most elaterid subfamilies can click. A spine on the prosternum can be snapped into a corresponding notch on the mesosternum, producing a violent "click" that can bounce the beetle into the air. Clicking is mainly used to avoid predation, although it is also useful when the beetle is on its back and needs to right itself. There are about 9300 known species worldwide, and 965 valid species in North America. Etymology Leach took the family name from the g ...

Arrhenotoky
Arrhenotoky (from Greek -τόκος ''-tókos'' "birth of -" + ἄρρην ''árrhēn'' "male person"), also known as arrhenotokous parthenogenesis, is a form of parthenogenesis in which unfertilized eggs develop into males. In most cases, parthenogenesis produces exclusively female offspring, hence the distinction. The set of processes included under the term arrhenotoky depends on the author: arrhenotoky may be restricted to the production of males that are haploid (haplodiploidy); may include diploid males that permanently inactivate one set of chromosomes (parahaploidy); or may be used to cover all cases of males being produced by parthenogenesis (including such cases as aphids, where the males are XO diploids). The form of parthenogenesis in which females develop from unfertilized eggs is known as thelytoky; when both males and females develop from unfertilized eggs, the term "deuterotoky" is used. In the most commonly used sense of the term, arrhenotoky is synonymous with ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xylem
Xylem is one of the two types of transport tissue in vascular plants, the other being phloem. The basic function of xylem is to transport water from roots to stems and leaves, but it also transports nutrients. The word ''xylem'' is derived from the Ancient Greek word (''xylon''), meaning "wood"; the best-known xylem tissue is wood, though it is found throughout a plant. The term was introduced by Carl Nägeli in 1858. Structure The most distinctive xylem cells are the long tracheary elements that transport water. Tracheids and vessel elements are distinguished by their shape; vessel elements are shorter, and are connected together into long tubes that are called ''vessels''. Xylem also contains two other type of cells: parenchyma and fibers. Xylem can be found: * in vascular bundles, present in non-woody plants and non-woody parts of woody plants * in secondary xylem, laid down by a meristem called the vascular cambium in woody plants * as part of a stelar arrangement n ...

Fusarium
''Fusarium'' is a large genus of filamentous fungi, part of a group often referred to as hyphomycetes, widely distributed in soil and associated with plants. Most species are harmless saprobes, and are relatively abundant members of the soil microbial community. Some species produce mycotoxins in cereal crops that can affect human and animal health if they enter the food chain. The main toxins produced by these ''Fusarium'' species are fumonisins and trichothecenes. Despite most species apparently being harmless (some existing on the skin as commensal members of the skin flora), some ''Fusarium'' species and subspecific groups are among the most important fungal pathogens of plants and animals. The name of ''Fusarium'' comes from Latin ''fusus'', meaning a spindle. Taxonomy The taxonomy of the genus is complex. A number of different schemes have been used, and up to 1,000 species have been identified at times, with approaches varying between wide and narrow concepts of speci ...

Symbiosis
Symbiosis (from Greek , , "living together", from , , "together", and , bíōsis, "living") is any type of a close and long-term biological interaction between two different biological organisms, be it mutualistic, commensalistic, or parasitic. The organisms, each termed a symbiont, must be of different species. In 1879, Heinrich Anton de Bary defined it as "the living together of unlike organisms". The term was subject to a century-long debate about whether it should specifically denote mutualism, as in lichens. Biologists have now abandoned that restriction. Symbiosis can be obligatory, which means that one or more of the symbionts depend on each other for survival, or facultative (optional), when they can generally live independently. Symbiosis is also classified by physical attachment. When symbionts form a single body it is called conjunctive symbiosis, while all other arrangements are called disjunctive symbiosis."symbiosis."

Robusta Coffee
''Coffea canephora'' ( syn. ''Coffea robusta'', commonly known as ''robusta coffee'') is a species of coffee that has its origins in central and western sub-Saharan Africa. It is a species of flowering plant in the family Rubiaceae. Though widely known as ''Coffea robusta'', the plant is scientifically identified as ''Coffea canephora'', which has two main varieties, ''robusta'' and '' nganda''. ''Coffea robusta'' represents 43% of global coffee production, with ''Coffea arabica'' constituting most of the remainder. There are several differences between the composition of coffee beans from ''C. arabica'' and ''C. robusta''. Beans from ''C. robusta'' tend to have lower acidity, more bitterness, and a more woody and less fruity flavor compared to ''C. arabica'' beans. Description Robusta is a species of flowering plant in the family Rubiaceae. Though widely known by the synonym ''Coffea robusta'', the plant is currently scientifically identified as ''Coffea canephora'', which ...

Melia Azedarach
''Melia azedarach'', commonly known as the chinaberry tree, pride of India, bead-tree, Cape lilac, syringa berrytree, Persian lilac, Indian lilac, or white cedar, is a species of deciduous tree in the mahogany family, Meliaceae, that is native to Indomalaya and Australasia. Description The fully grown tree has a rounded crown, and commonly measures tall, exceptionally . The leaves are up to long, alternate, long-petioled, two or three times compound (odd-pinnate); the leaflets are dark green above and lighter green below, with serrate margins. The flowers are small and fragrant, with five pale purple or lilac petals, growing in clusters. The fruit is a drupe, marble-sized, light yellow at maturity, hanging on the tree all winter, and gradually becoming wrinkled and almost white. As the stem ages and grows, changes occur that transform its surface into bark. Chemistry Italo et al 2009 and Safithri and Sari 2016 report flavonoids and phenols found in ''M. azed ...

Erythrina
''Erythrina'' is a genus of plants in the pea family, Fabaceae. It contains about 130 species, which are distributed in tropical and subtropical regions worldwide. They are trees, with the larger species growing up to in height. The generic name is derived from the Greek word , meaning "red", referring to the flower color of certain species. Names Particularly in horticulture, the name coral tree is used as a collective term for these plants. Flame tree is another vernacular name, but may refer to a number of unrelated plants as well. Many species of ''Erythrina'' have bright red flowers, and this may be the origin of the common name. However, the growth of the branches can resemble the shape of sea coral rather than the color of ''Corallium rubrum'' specifically, and this is an alternative source for the name. Other popular names, usually local and particular to distinct species, liken the flowers' red hues to those of a male chicken's wattles, and/or the flower shape to i ...

Khaya Grandifoliola
''Khaya grandifoliola'', also called African mahogany, Benin mahogany, large-leaved mahogany, or Senegal mahogany, is a species of plant in the family Meliaceae. It is found in Benin, the Democratic Republic of the Congo, Ivory Coast, Ghana, Guinea, Nigeria, Sudan, Togo, and Uganda. It is threatened by habitat loss. Medical uses In many malaria endemic countries, like the tropics, the extract of ''Khaya grandifoliola'' is used as an antimalarial herbal remedy. Recent studies show that 90% of malaria cases around the world come from sub-Saharan Africa. People in these areas resort to medicinal plants for treatment because alternative medical resources are often low or unavailable. The bark and seeds of ''Khaya grandifoliola'' are the most common parts used for treatment and are extracted by infusion or decoction. The extracts have proven to fight against the '' P. falciparum'' parasite, one of the vectors of malaria in humans. Crude water extracts of ''Khaya grandifoliola'' have s ...
