Bactrocera Passiflorae
''Bactrocera passiflorae'', the Fijian fruit fly, is a species of fly in the family Tephritidae in the insect order Diptera. It is native to several tropical and subtropical islands in the Pacific Ocean and is a pest of fruit crops. Description The adult ''Bactrocera passiflorae'' is similar in appearance to and slightly smaller than a housefly. It is black apart from yellow markings on the sides of the thorax and a triangular patch of yellow on the dorsal part of the hind part of the thorax. The wings are transparent with the exception of the dusky leading edge. Distribution and habitat ''Bactrocera passiflorae'' occurs on Fiji but not on Rotuma, on Niue, on Tonga and on Wallis and Futuna. It can be found where there is ripening fruit, in gardens, orchards, villages, towns and coastal locations, but not in dense forests. Its hosts include such fruits as passion fruit, guava, Indian almond, rose apple, cashew, breadfruit, pawpaw, kumquat, orange, mandarin, pomelo, man ...

Walter Wilson Froggatt
Walter Wilson Froggatt (13 June 1858 – 18 March 1937) was an Australian economic entomologist. Early life Froggatt was born in Melbourne, Victoria, the son of George Wilson Froggatt, an English architect, and his wife Caroline, daughter of Giacomo Chiosso, who came from a noble Italian family. As a child Froggatt, who was delicate, was encouraged by his mother to find interests in the open air and at an early age began collecting insects. The family having moved to Bendigo, Victoria he was educated at the Corporate High School, Sandhurst (Bendigo), and on leaving school spent four years on the land. In 1880 he went to a goldfield near Milparinka, New South Wales, and then worked his way northward and through Queensland to Mackay, Herberton, Cairns and other parts of the colony. Wherever he went he kept up his collecting of insects. Career as entomologist In 1883 Froggatt returned to Bendigo, worked with his father on a lease near Mount Hope, and around this time contacted Ch ...

Kumquat
Kumquats (; zh, 金桔), or cumquats in Australian English, are a group of small fruit-bearing trees in the flowering plant family Rutaceae. Their taxonomy is disputed. They were previously classified as forming the now-historical genus ''Fortunella'' or placed within ''Citrus'', . Different classifications have alternatively assigned them to anywhere from a single species, ''C. japonica'', to numerous species representing each cultivar. Recent genomic analysis would define three pure species, ''Citrus hindsii'', ''C. margarita'' and ''C. crassifolia'', with ''C. x japonica'' being a hybrid of the last two. The edible fruit closely resembles the orange (''Citrus sinensis'') in color and shape but is much smaller, being approximately the size of a large olive. The kumquat is a fairly cold-hardy citrus. Etymology The English name "kumquat" is a borrowing of the Cantonese ''gāmgwāt'' (). Origin The kumquat plant is native to Southern China. The historical reference to kum ...

Bacteria
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria are vital in many stages of the nutrient cycle by recycling nutrients such as the fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulphide and methane, to energy. Bacteria also live in symbiotic and parasitic relationsh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Honeydew (secretion)
Honeydew is a sugar-rich sticky liquid, secreted by aphids and some scale insects as they feed on plant sap. When their mouthpart penetrates the phloem, the sugary, high-pressure liquid is forced out of the anus of the aphid. Honeydew is particularly common as a secretion in hemipteran insects and is often the basis for trophobiosis. Some caterpillars of Lycaenidae butterflies and some moths also produce honeydew. Honeydew producing insects, like cicadas, pierce phloem ducts to access the sugar rich sap. The sap continues to bleed after the insects have moved on, leaving a white sugar crust called manna. Ants may collect, or "milk", honeydew directly from aphids and other honeydew producers, which benefit from their presence due to their driving away predators such as lady beetles or parasitic wasps—see ''Crematogaster peringueyi''. Animals and plants in a mutually symbiotic arrangement with ants are called Myrmecophiles. In Madagascar, some gecko species in the genera ''Ph ...

Nectar
Nectar is a sugar-rich liquid produced by plants in glands called nectaries or nectarines, either within the flowers with which it attracts pollinating animals, or by extrafloral nectaries, which provide a nutrient source to animal mutualists, which in turn provide herbivore protection. Common nectar-consuming pollinators include mosquitoes, hoverflies, wasps, bees, butterflies and moths, hummingbirds, honeyeaters and bats. Nectar plays a crucial role in the foraging economics and evolution of nectar-eating species; for example, nectar foraging behavior is largely responsible for the divergent evolution of the African honey bee, ''A. m. scutellata'' and the western honey bee. Nectar is an economically important substance as it is the sugar source for honey. It is also useful in agriculture and horticulture because the adult stages of some predatory insects feed on nectar. For example, a number of parasitoid wasps (e.g. the social wasp species ''Apoica flavissima'') rely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inocarpus Fagifer
''Inocarpus fagifer'', commonly known as the Tahitian chestnut or Polynesian chestnut, is a species of flowering plant in the subfamily Faboideae of the legume family, Fabaceae. The tree has a wide range in the tropics of the south-west Pacific and south-east Asian regions, and a history of traditional use by the peoples of Polynesia and Melanesia. It is the only edible and culturally important member of the genus ''Inocarpus''. Description There is great diversity in the size, form, shape and colour of the Tahitian chestnut, and of its leaves, flowers and fruit. Because of its long history of cultivation and its tendency to become naturalised where introduced, it is likely that, over its wide range, the species contains several originally farmer-selected cultivars that have not been recognised or described. Size, form and lifespan The Tahitian chestnut is a medium-sized, evergreen tropical tree. It may grow to 30 m in height, though 20 m is more usual, with a crown dia ...

Cerbera Manghas
''Cerbera manghas'', the sea mango, is a small evergreen coastal tree growing up to tall. It is native to coastal areas in Africa, Asia, Australasia, and the Pacific islands. It is classified as one of the three species in the genus Cerbera that constitute as mangroves. Description The shiny dark-green leaves grow in a spiral arrangement, and are ovoid in shape. The flowers are fragrant, possessing a white tubular five-lobed corolla about in diameter, with a pink to red throat. They have five stamens and the ovary is positioned above the other flower parts. The fruits are egg-shaped, long. At maturity they turn bright red. Toxicity The leaves and the fruits contain the potent cardiac glycoside cerberin, which is extremely poisonous if ingested. This was utilised in trials of ordeal done towards criminal suspects in the Merina Kingdom ruling the island of Madagascar until the practice was abolished during Radama II's reign. On the opposite spectrum, Fijians use its (''vasa'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Syzygium Malaccense
''Syzygium malaccense'' is a species of flowering tree native to tropical Asia and Australia. It is one of the species cultivated since prehistoric times by the Austronesian peoples. They were carried and introduced deliberately to Remote Oceania as canoe plants. In modern times, it has been introduced throughout the tropics, including many Caribbean countries and territories. Names ''Syzygium malaccense'' has a number of English common names. It is known as a Malay rose apple, or simply Malay apple, mountain apple, rose apple, Otaheite apple, pink satin-ash, plumrose and ''pommerac'' (derived from ''pomme Malac'', meaning "Malayan apple" in French). Despite the fact that it is sometimes called the Otaheite cashew, it is not related to cashew. While cashew nuts (but not cashew fruits) may trigger allergic reactions, rose apple fruit has not been observed to do so. In Costa Rica is known as Manzana de Agua. It is found mainly in the rainy zones on the Atlantic Coast of the cou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mango
A mango is an edible stone fruit produced by the tropical tree ''Mangifera indica''. It is believed to have originated in the region between northwestern Myanmar, Bangladesh, and northeastern India. ''M. indica'' has been cultivated in South and Southeast Asia since ancient times resulting in two types of modern mango cultivars: the "Indian type" and the "Southeast Asian type". Other species in the genus ''Mangifera'' also produce edible fruits that are also called "mangoes", the majority of which are found in the Malesian ecoregion. Worldwide, there are several hundred cultivars of mango. Depending on the cultivar, mango fruit varies in size, shape, sweetness, skin color, and flesh color which may be pale yellow, gold, green, or orange. Mango is the national fruit of India, Pakistan and the Philippines, while the mango tree is the national tree of Bangladesh. Etymology The English word ''mango'' (plural "mangoes" or "mangos") originated in the 16th century from the Por ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
