Ptyelus Grossus
''Ptyelus grossus'' is an Auchenorrhynchan spittlebug in the family Aphrophoridae. Occurring from Southern Africa through to West Africa, the species is gregarious in its larval and nymph stages, feeding on a variety of plants, and producing protective nests of acrid foam from the plant's sap. Excreted in large quantities, the foam drips incessantly causing wet patches on the soil below. Adults have slate-grey wings, each wing with two white and yellow patches near the outer margin. The head is white, rounded with large dark eyes and small black and yellow marks on the forehead. Favoured trees are '' Tipuana'', '' Peltophorum'' and ''Lonchocarpus'', although its catholic diet includes species of ''Grevillea'', '' Rhus'', '' Acacia'', ''Vangueria'' and even ''Eucalyptus ''Eucalyptus'' () is a genus of over seven hundred species of flowering trees, shrubs or mallees in the myrtle family, Myrtaceae. Along with several other genera in the tribe Eucalypteae, including '' Corym ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lonchocarpus
''Lonchocarpus'' is a plant genus in the legume family (biology), family (Fabaceae). The species are called lancepods due to their fruit resembling an ornate lance tip or a few beads on a string. ''Cubé'' resin is produced from the roots of ''Lonchocarpus urucu, L. urucu'' and namely 'Lonchocarpus utilis, L. utilis'' (''cubé''). It contains enough of the toxic rotenoids rotenone and deguelin to be used as an insecticide and piscicide. As these are naturally occurring compounds, they were formerly used in organic farming. Since it is highly unselective and kills useful, as well as pest, animals, it is considered harmful to the environment today. Also, Chronic (medicine), chronic exposure to rotenone and deguelin seems to increase the risk of Parkinson's disease even in mammals, for which these compounds are less Acute (medicine), acutely toxic than for fish and insects. On the other hand, deguelin might be useful in cancer therapy if it can be applied directly into tumors, and ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Drosophilidae
The Drosophilidae are a diverse, cosmopolitan family of flies, which includes species called fruit flies, although they are more accurately referred to as vinegar or pomace flies. Another distantly related family of flies, Tephritidae, are true fruit flies because they are frugivorous, and include apple maggot flies and many pests. The best known species of the Drosophilidae is ''Drosophila melanogaster'', within the genus ''Drosophila'', also called the "fruit fly." ''Drosophila melanogaster'' is used extensively for studies concerning genetics, development, physiology, ecology and behaviour. Many fundamental biological mechanisms were discovered first in ''D. melanogaster.'' The fruit fly is mostly composed of post-mitotic cells, has a very short lifespan, and shows gradual aging. As in other species, temperature influences the life history of the animal. Several genes have been identified that can be manipulated to extend the lifespan of these insects. Additionally, ''Drosophi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gorytini
Gorytini is a large and morphologically very diverse group of hunting wasps distributed worldwide and particularly species-rich in tropical areas. Most species hunt various hemipterans, especially among the Auchenorrhyncha, which they sting, paralyze, and provision in underground nests as food for their larvae. Taxonomy The ''Catalog of Sphecidae'' doesn't recognise Gorytini as a tribe and instead places the genera in subtribes Exeirina, Gorytina, Handlirschina and Spheciina within tribe Bembicini. * Gorytina **'' Afrogorytes'' **'' Allogorytes'' **'' Arigorytes'' **'' Aroliagorytes'' **'' Austrogortyes'' **'' Eogorytes'' **'' Epigorytes'' **''Gorytes'' (='' Leiogorytes'', ='' Pseudoplisus'') **'' Hapalomellinus'' **'' Harpactostigma'' **'' Harpactus'' **'' Hoplisoides'' **'' Lestiphorus'' **'' Leurogorytes'' **''Liogorytes'' **'' Megistommum'' **'' Oryttus'' **'' Psammaecius'' **'' Psammaletes'' **''Sagenista'' **'' Saygorytes'' **'' Stenogorytes'' **'' Stethogorytes' ...

Eucalyptus
''Eucalyptus'' () is a genus of over seven hundred species of flowering trees, shrubs or mallees in the myrtle family, Myrtaceae. Along with several other genera in the tribe Eucalypteae, including '' Corymbia'', they are commonly known as eucalypts. Plants in the genus ''Eucalyptus'' have bark that is either smooth, fibrous, hard or stringy, leaves with oil glands, and sepals and petals that are fused to form a "cap" or operculum over the stamens. The fruit is a woody capsule commonly referred to as a "gumnut". Most species of ''Eucalyptus'' are native to Australia, and every state and territory has representative species. About three-quarters of Australian forests are eucalypt forests. Wildfire is a feature of the Australian landscape and many eucalypt species are adapted to fire, and resprout after fire or have seeds which survive fire. A few species are native to islands north of Australia and a smaller number are only found outside the continent. Eucalypts have been grow ...

Vangueria
''Vangueria'' is a genus of flowering plants in the family Rubiaceae. The genus is named for , as '' V. madagascariensis'' is known in Malagasy. Distribution The genus contains over 50 species distributed in Africa south of the Sahara with one species occurring in Madagascar ('' V. madagascariensis''). The centre of diversity is in East Africa (Kenya, Tanzania) and they are rare in West Africa. Bacterial leaf symbiosis Endophytic bacteria are housed in the intercellular space of the leaf mesophyll tissue. The presence of these bacteria can only be microscopically ascertained. The bacteria are identified as ''Burkholderia'', which is a genus that is also found in the leaves of other Rubiaceae species. The hypothesis is that these endophytic bacteria provide chemical protection against insect herbivory. Gousiekte Several ''Vangueria'' species - '' V. latifolia'', '' V. pygmaea'', '' V. thamnus'' - are known to cause , a cardiotoxicosis of ruminants characterised by heart failure ...

Acacia
''Acacia'', commonly known as the wattles or acacias, is a large genus of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa and Australasia. The genus name is New Latin, borrowed from the Greek (), a term used by Dioscorides for a preparation extracted from the leaves and fruit pods of ''Vachellia nilotica'', the original type of the genus. In his ''Pinax'' (1623), Gaspard Bauhin mentioned the Greek from Dioscorides as the origin of the Latin name. In the early 2000s it had become evident that the genus as it stood was not monophyletic and that several divergent lineages needed to be placed in separate genera. It turned out that one lineage comprising over 900 species mainly native to Australia, New Guinea, and Indonesia was not closely related to the much smaller group of African lineage that contained ''A. nilotica''—the type species. This meant that the Australasian lineage (by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhus
Sumac ( or ), also spelled sumach, is any of about 35 species of flowering plants in the genus ''Rhus'' and related genera in the cashew family (Anacardiaceae). Sumacs grow in subtropical and temperate regions throughout the world, including East Asia, Africa, and North America. Sumac is used as a spice, as a dye, and in medicine. Description Sumacs are dioecious shrubs and small trees in the family Anacardiaceae that can reach a height of . The leaves are usually pinnately compound, though some species have trifoliate or simple leaves. The flowers are in dense panicles or spikes long, each flower very small, greenish, creamy white or red, with five petals. The fruits are reddish, thin-fleshed drupes covered in varying levels of hairs at maturity and form dense clusters at branch tips, sometimes called sumac bobs. Sumacs propagate both by seed (spread by birds and other animals through their droppings), and by new shoots from rhizomes, forming large clonal colonies. Taxonomy ...

Grevillea
''Grevillea'', commonly known as spider flowers, is a genus of about 360 species of evergreen flowering plants in the family Proteaceae. Plants in the genus ''Grevillea'' are shrubs, rarely trees, with the leaves arranged alternately along the branches, the flowers zygomorphic, arranged in racemes at the ends of branchlets, and the fruit a follicle that splits down one side only, releasing one or two seeds. Description Plants in the genus ''Grevillea'' are shrubs, rarely small trees with simple or compound leaves arranged alternately along the branchlets. The flowers are zygomorphic and typically arranged in pairs along a sometimes branched raceme at the ends of branchlets. The flowers are bisexual, usually with four tepals in a single whorl. There are four stamens and the gynoecium has a single carpel. The fruit is a thin-walled follicle that splits down only one side, releasing one or two seeds before the next growing season.
