Saccharum Robustum
''Saccharum robustum'', the robust cane, is a species of plant found in New Guinea. Ecology ''Eumetopina flavipes'', the island sugarcane planthopper, a species of planthopper present throughout South East Asia and is a vector for the Ramu stunt disease, a plant disease which affects sugarcane, occurs also on ''S. robustum''. The pink sugarcane borer (''Sesamia grisescens''), a moth of the family Noctuidae found in Papua New Guinea, Seram, the Moluccas and New Britain, also feeds on ''S. robustum''. ''Scirpophaga excerptalis'', the white top borer or the sugarcane top borer, a moth in the family Crambidae, also feeds on ''S. robustum''.

Eumetopina Flavipes
''Eumetopina flavipes'', the island sugarcane planthopper, is a species of planthopper present throughout South East Asia. ''E. flavipes'' is a vector for Ramu stunt disease, a plant disease which affects sugarcane. Ramu stunt disease is widespread throughout Papua New Guinea, but has not been detected in Australia. ''Eumetopina'' is thought to have evolved in Papua New Guinea, where up to four undescribed species have been collected, but many more may be present. In Papua New Guinea, ''E. flavipes'' occurs on ''Saccharum officinarum'', '' S. robustum'', '' S. edule'' and ''Saccharum'' hybrids sugarcane. Virus-free populations of ''E. flavipes'' are present on ''Saccharum'' hybrids and ''S. officinarum'' on many islands in the Torres Strait, and a number of small populations persist on the northern Cape York Peninsula Cape York Peninsula is a large peninsula located in Far North Queensland, Australia. It is the largest unspoiled wilderness in northern Australia.Mittermeier, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ramu Stunt Disease
The Ramu stunt disease is a disease of the sugarcane widespread throughout Papua New Guinea, but not detected in Australia. '' Eumetopina flavipes'', the island sugarcane planthopper, is a species of planthopper present throughout South East Asia which is a vector for the disease. It was first detected in the 1980s. It is thought to be either of viral origin or associated with a ''Phytoplasma'' bacterium.The Phytoplasma Associated with Ramu Stunt Disease of Sugarcane Is Closely Related to the White Leaf Phytoplasma Group.

Sesamia Grisescens
''Sesamia grisescens'', the pink sugarcane borer, pink stalk borer, shoot borer, sugarcane borer or ramu shoot borer, is a moth of the family Noctuidae. The species was first described by Warren in 1911. It is found in Papua New Guinea, Seram, the Moluccas and New Britain. The larvae are a pest on ''Saccharum officinarum'', although they also feed on other plants, including ''Saccharum robustum'', ''Saccharum spontaneum'', ''Saccharum edule'', ''Pennisetum purpureum ''Cenchrus purpureus'', synonym ''Pennisetum purpureum'', also known as Napier grass, elephant grass or Uganda grass, is a species of perennial tropical grass native to the African grasslands. arrell, G., Simons, S.

Scirpophaga Excerptalis
''Scirpophaga excerptalis'', the white top borer or sugarcane top borer, is a moth in the family Crambidae. It was described by Francis Walker in 1863. It is found in southern Asia from the Indian Subcontinent in the west to southern China in the east, south to New Guinea, possibly Australia and the Solomon Islands. Description The wingspan is 22–28 mm for males and 26–35 mm for females. The forewings and hindwings are white with an orange-red anal tuft in females. Similar species Many, if not all, records of the moth ''Scirpophaga nivella'' in the cane fields of Asia are in fact of ''S. excerptalis''. All species of ''Scirpophaga'' are indistinguishable from each other as caterpillars, very difficult to distinguish as females, and can best be distinguished by examining the male genitalia or by sequencing and comparing the DNA. Chen & Wu find the males resemble ''S. magnella'' the most in their key to the genitalia of the genus, with ''S. tongyaii'' slig ...

Domesticated Plants And Animals Of Austronesia
One of the major human migration events was the maritime settlement of the islands of the Indo-Pacific by the Austronesian peoples, believed to have started from at least 5,500 to 4,000 BP (3500 to 2000 BCE). These migrations were accompanied by a set of domesticated, semi-domesticated, and commensal plants and animals transported via outrigger ships and catamarans that enabled early Austronesians to thrive in the islands of Maritime Southeast Asia (also known as 'Island Southeast Asia'. e.g.: Philippines, Indonesia), Near Oceania (Melanesia), Remote Oceania (Micronesia and Polynesia), Madagascar, and the Comoros Islands. They include crops and animals believed to have originated from the Hemudu and Majiabang cultures in the hypothetical pre-Austronesian homelands in mainland China, as well as other plants and animals believed to have been first domesticated from within Taiwan, Maritime Southeast Asia, and New Guinea. Some of these plants are sometimes also known as "ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saccharum
''Saccharum'' is a genus of tall perennial plants of the broomsedge tribe within the grass family. The genus is widespread across tropical, subtropical, and warm temperate regions in Africa, Eurasia, Australia, the Americas, and assorted oceanic islands. Several species are cultivated and naturalized in areas outside their native habitats.Welker, C. A. D. & H. M. Longhi-Wagner. 2012. The genera ''Eriochrysis'' P. Beauv., ''Imperata'' Cirillo and ''Saccharum'' L. (Poaceae - Andropogoneae - Saccharinae) in the state of Rio Grande do Sul, Brazil. Brazilian Journal of Botany 35(1): 87–105. ''Saccharum'' includes the sugarcanes. They have stout, jointed, fibrous stalks that are generally rich in sugar, and measure two to six m (6 to 19 ft) tall. All sugarcane species interbreed and the major commercial cultivars are complex hybrids. Species , Plants of the World Online accepted the following species: * ''Saccharum alopecuroidum'' (L.)
