Coconut Lethal Yellowing Diseases: A Phytoplasma Threat to Palms of Global Economic and Social Significance
The recent discovery of Bogia coconut syndrome in Papua New Guinea (PNG) is the first report of a lethal yellowing disease (LYD) in Oceania. Numerous outbreaks of LYDs of coconut have been recorded in the Caribbean and Africa since the late Nineteenth century and have caused the death of millions of palms across several continents during the Twentieth century. Despite the severity of economic l...
متن کاملMolecular detection and characterization of phytoplasmas associated with lethal yellowing disease of coconut palms in Jamaica
Tissue samples were collected from coconut palms with symptoms of lethal yellowing (LY) disease in Jamaica. Palms were sampled at 50 sites exhibiting varying levels of mortality due to LY. Samples were assayed for phytoplasma infection by polymerase chain reaction (PCR) assays. Detected phytoplasmas were characterized by dot blot nucleic acid hybridisation, restriction fragment length polymorph...
متن کاملIdentification and molecular characterization of the phytoplasma associated with a lethal yellowing-type disease of coconut in Côte d’Ivoire
Coconut palms from the Grand-Lahou region of Côte d’Ivoire exhibiting lethal yellowing-like symptoms and infected by a phytoplasma were further tested for the characterization of the phytoplasma pathogen based on the 16S rRNA gene analysis. Nested PCR with phytoplasma universal and lethal yellowing-specific primers resulted in amplification of products of expected sizes from seven out of 17 sym...
متن کاملBiochemical changes in carbohydrate metabolism of the fish – Cyprinus carpio during sub-lethal exposure to biopesticide – Derisom.
The effect of biopesticide - Derisom on certain metabolites and enzymes of carbohydrate metabolism were evaluated in gill, liver, kidney and muscle of Cyprinus carpio during sub-lethal toxicity exposure of 21 days. A dose of 0.28 ppm was taken as the sub-lethal dose. The organs were taken from exposed and control fish at the end of 24 hrs, 7, 14 and 21 days and used for the estimation of total ...
متن کاملEffect of Various Antibiotics on Development of Lethal Yellowing in Coconut Palm
Fifty coconut palms exhibiting early symptoms of lethal yellowing were selected for treatment with oxytetracycline-HCl, tetracyclineHC1, streptomycin nitrate, potassium penicillin-G, or griseofulyin. Two grams of antibiotic in 0.2 or 1.0 liters of water were pressure injected into the trunk of each tree except for the griseofulvin treatments which were applied as a paste into holes bored in the...
