Aphelenchoides Ritzemabosi
''Aphelenchoides ritzemabosi'' (black currant nematode, chrysanthemum foliar nematode, chrysanthemum leaf nematode, chrysanthemum nematode, chrysanthemum foliar eelworm) is a plant pathogenic nematode. It was first scientifically described in 1890 in England. This nematode has a wide host range. Among the most important species affected are Chrysanthemums and strawberries. ''A. ritzemabosi'' is a migratory foliar feeding nematode. It can feed both ectoparasitically and endoparasitically, with the later causing the most significant damage. When adequate moisture is present, this nematode enters the leaves and feeds from inside the tissue. Typical damage is characterized by necrotic zones between the veins of the leaves. Its lifecycle is short; only ten days from egg to mature adult. A single female can lay as many as 3,500 eggs. This pest can be difficult to control. Host plant resistance, hot water treatments, and predatory mites are recommended. Nomenclature and synony ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aphelenchoides Besseyi
''Aphelenchoides besseyi'' is a plant pathogenic nematode. It is sometimes referred to as ''rice white tip'', ''spring dwarf'', ''strawberry bud'', ''flying strawberry nematode'' or ''strawberry crimp disease'' nematode. This foliar nematode is found in Africa, North, Central, and South America, Asia, Eastern Europe, and Pacific islands.Bridge, J., and Jim L.

Aphelenchoides Bicaudatus
''Aphelenchoides bicaudatus'' is a nematode parasite of '' Elaeidobius kamerunicus'', '' Vigna marina'', and ''Agaricus bisporus''. Distribution In June 1980 ''E. kamerunicus'' were imported from Cameroon to Malaysia. They were needed to pollinate ''Elaeis guineensis'', which until then had been inadequately pollinated by whatever native insects were around. The pupae were found to be severely infested with ''A. bicaudatus'' and so were treated until nematode-free before being released. It occurs commonly as a soil organism in New South Wales. ''A. bicaudatus'' is also found in: Libya, China, India, and Brazil. Protein expression ''A. bicaudatus'' may be distinguished from other ''Aphelenchoides'' and ''Ditylenchus angustus'' and '' D. myceliophagus'' by some of their α- and β-esterase In biochemistry, an esterase is a class of enzyme that splits esters into an acid and an alcohol in a chemical reaction with water called hydrolysis (and as such, it is a type of hydrolase). ...

Foliar Nematodes
Foliar nematodes are plant parasitic roundworms in the genus '' Aphelenchoides''. The three most economically important species are '' Aphelenchoides fragariae'', ''A. ritzemabosi'', and ''A. besseyi''. Foliar nematodes are becoming a widespread and serious problem for the ornamental and nursery industries. ''A. fragariae'' causes damage on hundreds of different plants including chrysanthemum, begonia, gloxinia, African violet, cyclamen, and a wide variety of bedding plants and ferns, causing brown to black, vein-delimited lesions on leaf tissue, defoliation, and possible stunting of plants. Biology While many plant parasitic nematodes feed on plant roots, foliar nematodes live and reproduce inside the leaves of plants. The nematodes live within the epidermis and mesophyll tissues of leaves, which causes necrosis and collapse of the palisade and spongy parenchyma tissues. Inside the leaves of plants female nematodes lay one or two eggs a day, with each female producing up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
