Holo- and paratypes of Meloidogyne mayaguensis Rammah & Hirschmann,
1988 and M. enterolobii Yang & Eisenback, 1983 were compared
morphometrically and morphologically. All female, male and second-stage juvenile
morphometrical and morphological characters are identical for the two species.
Meloidogyne mayaguensis is confirmed as a junior synonym for M. enterolobii
(Karssen et al., 2012).
Reported median body size for this species (Length mm; width micrometers; weight micrograms) - Click:
Brazil, Mexico, Malawi, South Africa, and West Africa (Senegal, Ivory
Coast and Burkina Faso). China, Vietnam, Florida, Central and South America,
France, and Switzerland. Widely distributed in the Caribbean islands, including Cuba, Puerto Rico,
Tobago, Trinidad, Guadeloupe and Martinique.
Reported from cotton and soybean in the United States (Ye et al., 2013)
M. enterolobii was first described from roots of pacara earpod trees
(Enterolobium contortisiliquum) on Hainan Island in China. A few years
after the description of M. enterolobii, M. mayaguensis was described
from eggplant in Puerto Rico. Morphometric and molecular analysesd
support the designation of M. mayaguensis as a junior synonym of M.
(Elling, 2013; Karssen, 2012).
Regulatory agencies of several have designated M. enterolobii
as a quarantine pathogen (Elling, 2013).
Populations of Meloidogyne enterolobii are able to overcome resistance
of the Mi gene in
tomato cv. Rossol, soybean cv. Forrest, and sweet potato are reported in West
Damages coffee in Cuba where it also reproduces on tomatoes with the
Mi resistance gene.
It is considered the most important problem in guava production in Brazil
where it infests over 5,000 ha or about a third of the production area (Elling,
Feeding site establishment and
development typical of genus.
Meloidogyne enterolobii has a very wide host range comparable to
that of M. incognita. It includes vegetables, guava, acerola, ornamentals,
and weeds. Eggplant (Solanum melongena) was the host, first reported for
M. (mayaguensis) enterolobii in
Puerto Rico. Other recorded hosts include bell pepper (Capsicum annuum),
soybean (Glycine max), sweet potato (Ipomoea batatas), tobacco (Nicotiana
tabacum), tomato (Solanum lycopersicum), and watermelon (Citrullus
lanatus), coffee (Coffea arabica), bean (Phaseolus vulgaris),
beet (Beta vulgaris), broccoli (Brassica oleracea var. Botrytis),
celery (Apium graveolens), horsebean (Cannavalia ensiformis),
parsley (Petroselynum crispum), potato (Solanum tuberosum), and
pumpkin (Cucurbita sp.).
Guava (Psidium guajava) is also a good host and the nematode has been found on
other tropical fruit trees (Annona sp., Pouteria sapota,
Euphorbia longana, Chrysophyllum cainito).
Spanish needle (Bidens pilosa) is a weed host.
In Florida, M. enterolobii has been found associated with ornamentals,
of angel trumpet (Brugmansia 'Sunray'), cape honeysuckle (Tecomaria
capensis), glory bush (Tibouchina elegans), ajuga, carpet bugleweed (Ajuga
reptans), and Uganda gloryflower (Clerodendrum ugandense). Also,
Thunbergia spp., Tithonia spp., Torenia spp.,
Trachelospermum spp. and Hibiscus sp.
Above-ground symptoms include yellowing and stunting; roots have large galls.
In guava decline in Brazil, M. enterolobii interacts
synergistically with Fusarium solani. The fungus does not cause
root-rot unless it is in a disease complex with M. enterolobii (Elling,
