Aggressiveness and Damage Potential of Central American and Caribbean Populations of Radopholus spp. in Banana.
Monoxenic cultures of burrowing nematode populations extracted from banana roots from Belize, Guatemala, Honduras, and Costa Rica were established on carrot discs. Cultures of Radopholus spp. were also obtained from Florida, Puerto Rico, Dominican Republic, and Ivory Coast. The aggressiveness (defined as reproductive fitness and root necrosis) of these populations was evaluated by inoculating b...
متن کاملCharacterization of a New Burrowing Nematode Population, Radopholus citrophilus, from Hawaii.
Karyotype, host preference, isozyzme patterns, morphometrics, and mating behavior of two burrowing nematode populations from Hawaii, one infecting Anthurium sp. and the second infecting Musa sp., were compared with Radopholus similis and R. citrophilus populations from Florida. The population from Anthurium sp. had five chromosomes (n = 5), and that from Musa sp. had four (n = 4). Neither of th...
متن کاملWorldwide dissemination of Radopholus similis and its importance in crop production.
The burrowing nematode, Radopholus similis, attacks agronomic and horticultural crops and many weeds, and is reported to reproduce on more than 250 plant species. Two races of R. similis are recognized. Although one race attacks citrus and the other race does not, they are morphologically similar. At present, the citrus race is found attacking citrus only in Florida, U.S.A., but it is known to ...
متن کاملAseptic Culture Systems of Radopholus similis for In Vitro Assays on Musa spp. and Arabidopsis thaliana.
Radopholus similis is one of the most damaging nematodes in bananas. Chemical control is currently the most-used method, but nematode control through genetic improvement is widely encouraged. The objective of this study was to establish an aseptic culture system for R. similis and determine whether R. similis can infect and reproduce on in vitro banana plantlets and in vitro Arabidopsis thalian...
متن کاملMonoxenic Culture of Banana-Parasitic Nematodes on Musa acuminata cv. Poyo shoots.
Among nematodes parasitizing bananas throughout the world, Radopholus similis and Helicotylenchus multicinctus are the most widespread and damaging species. Besides these two nematodes, Hoplolaimus pararobustus is encountered frequently in Ivory Coast and has been increasing in banana growing areas for the past 25 years (6,10). In vitro culture systems could facilitate screening for resistance ...
