Perineal pattern: Rounded to dorso-ventrally oval with fine but widely spaced striae, somewhat similar to that of M. incognita and M. arenaria in having rounded dorsal arch, fine striae and lateral lines being absent (cf. double lateral lines in M. javanica) or represented by occasional breaks or a short line on one side of pattern at junction of dorsal and ventral arches. There is a prominent tail tip area (larger in size than that of M. javanica; absent in M. incognita and M. arenaria) which is circular and usually free of striae. Anal fold present. Phasmids small pore-like, one vulva slit length (21-30 µm) apart. Lateral striations on either side of vulva slit present. Egg masses small, with 150-200 eggs in each. Eggs 88-111 (98)×38-50 (44) µm.

Males: Body vermiform, 1.17-1.74 (1.5) mm long, slender (a =31-50 (40)). Head elevated, rectangular, continuous, not annulated. Stylet 21-25 (23) µm long; shaft with irregular thickness and lumen diameter; knobs rounded, distinctly separate, 4.3-5.6 (5) µm across, set off from shaft. Spicules and gubernaculum 24-31 (28) µm and 6-9 (7) µm long, respectively. Tail short; phasmids preanal, near mid-spicule level.

Second-stage juveniles: Body vermiform, 0.39-0.53 (0.45) mm long. Lateral field with 4 incisures. Stylet 11-12 µm long; conus about half its total length; knobs small, rounded with posteriorly sloping anterior surfaces. Dorsal oesophageal gland orifice 3.3-4.3 µm behind stylet. Oesophagus typical of the genus with elongate glands extending on ventral side of intestine. Excretory pore 80-98 (88) µm from anterior end of body. Rectum inflated. Tail elongate-conoid to a bluntly pointed tip, 49-63 (54) µm long or 4.3-5.7 (5) times as long as anal body width; hyaline terminal part distinctly set off.

Distribution

Top of page M. mayaguensis was described originally from aubergine in Puerto Rico where tomato, tobacco, Capsicum and watermelon are good hosts (Rammah, 1989; Rammah and Hirschmann, 1988). In Senegal, it is widespread and occurs along with other Meloidogyne species on tomato (Duponnois et al., 1995). In Nelspruit, Mpumalanga Province, South Africa, commercial guava and Bidens pilosa are preferred hosts (Willers, 1997b).

M. mayaguensis parasitizes coffee in Cuba (Decker and Rodriguez Fuentes, 1989) and occurs sympatrically with Meloidogyne incognita, M. arenaria and M. javanica (Rodriguez et al., 1995). The species also occurs in several states in Brazil (Carneiro et al., 2001; Torres et al., 2004, 2005) on coffee and guava and a single isolation was recorded from soil around trees, palms, shrubs and herbaceous species in a preserved area of Atlantic forest in Brazil (Lima et al., 2005).

Hosts/Species Affected

Top of page Tomato, aubergine, tobacco, pepper (Capsicum annuum) and watermelon are good hosts for Meloidogyne mayaguensis (Rammah and Hirschmann, 1988). Guava and Bidens pilosa are also good hosts and may occur side by side thus serving as alternative hosts (Willers, 1997b). Coffee is severely parasitized in Cuba (Decker and Rodriguez Fuentes, 1989) and M. mayaguensis is also recorded from coffee in Brazil (Carneiro et al., 2004). On coffee in Cuba M. mayaguensis occurs sympatrically with Meloidogyne incognita, M. arenaria and M. javanica (Rodriguez et al., 1995). It is widespread on tomato in Senegal (Duponnois et al., 1995). It occurs on guava in north-eastern Brazil (Carneiro et al., 2001, Torres et al., 2004, 2005). Guimaraes et al. (2003) presented data on M. mayaguensis parasitism on various plant species in Brazil. They found that common bean (Phaseolus vulgaris), cowpea, tomato and Crotalaria juncea were susceptible whereas groundnut, maize and C. spectabilis were resistant. In tomato, the Mi gene for root-knot resistance was not effective against M. mayaguensis. The groundnut roots showed high numbers of adult females, although no eggs were observed. Maranhao et al. (2003) indicated that some genotypes of Psidium guineense varied from slightly to highly susceptible to M. mayaguensis, although showing some resistance to other root-knot nematodes, whereas others showed moderate resistance.

Symptoms

Top of page M. mayaguensis induces severe root galling in heavily attacked plants or trees. Attacked guava trees show general decline symptoms, noticed as yellowing of leaves and defoliation, and may die in 3 years. Declining trees occur in patches bordered by relatively healthy trees.

Biology and Ecology

Impact

Top of page M. mayaguensis parasitizes coffee in Cuba and occurs sympatrically with, and is more damaging than, Meloidogyne incognita, M. arenaria and M. javanica (Rodriguez et al., 1995). Severe root galling was observed on commercial guava in Nelspruit, South Africa. The attacked trees declined severely or died within 3 years (Willers, 1997b). Bidens pilosa, growing between guava trees, were heavily infested providing a source of infection (Willers, 1997b). M. mayaguensis was also reported causing galling to guava in Brazil (Carneiro et al., 2001). Carneiro et al. (2001) reported M. mayaguensis causing severe damage to commercial guava orchards in Pernambuco and Bahia states. Infested trees had a drastic reduction in growth, reduced leaf size and a decline in yield quantity and quality. Severely infested root systems were poorly developed and were distorted by multiple galls of various sizes. The authors speculated that the nematode had probably been spread from infected nurseries.

M. mayaguensis is more capable of breaking resistance than other common tropical species. Following the use of resistant cultivars, the resistance-breaking lines, with the pVI esterase phenotype using RFLP, were shown to belong to the species M. mayaguensis. These were not lines selected from other existing species of Meloidogyne such as M. incognita, M. arenaria, M. javanica and M. hapla (Fargette et al., 1996). Resistance studies have been done by Maranhao et al. (2003) and Rubio-Cabetas et al. (1999) who reported that the Ma gene from Myrobalan plum (Prunus cerasifera) conferred resistance to M. mayaguensis.

Detection and Inspection

Top of page The root galls have to be collected and the nematode identified particularly by the morphometrics of second-stage juveniles and the perineal patterns of females.

Attacked guava trees show general decline symptoms and may die in 3 years; declining trees occur in patches bordered by trees in a relatively better condition (Willers, 1997b).

Much emphasis has been placed on developing biochemical and molecular diagnostic protocols in order to reliably distinguish M. mayaguensis from other root-knot nematodes (Carneiro et al., 2000; Blok et al., 2002; Brito et al., 2004; Randig et al., 2004; Fargette et al., 2005; Molinari et al., 2005; Skantar and Carta, 2005).

Similarities to Other Species/Conditions

Top of page This is a typical species of Meloidogyne with host response similar to M. incognita race 2 but quite different in morphological characters. It resembles (see Hewlett and Tarjan (1983) and Jepson (1987) for details of related species) M. incognita, M. javanica, M. arenaria and M. enterolobii from which it can be differentiated by its typical perineal pattern supported by morphological and morphometric characters, particularly of head and stylet of female and male and body length, stylet, rectum and tail of second-stage juvenile. M. mayaguensis can also be distinguished from other root-knot species by esterase pattern and molecular methodologies.

Prevention and Control

Top of page

Chemical Control

Moreira and Henriques Neto (2001) studied the control of M. mayaguensis on guava seedlings in Brazil. They used various nematicides but did not demonstrate a reduction in the development of the nematode population.

Biological Control

In Senegal, the two local strains (ORS 18692 S7 and ORS 18692 S5) of the nematophagous fungus Arthrobotrys oligospora trapped 98% of groups of 7-day-old M. mayaguensis juveniles within 48 h; optimal growth occurred at 25-30°C and at pH 5.6, but salinity inhibited development. When the fungus was incorporated into compost blocks before sowing and transplanting tomato seedlings, it reduced M. mayaguensis populations and stimulated seedling growth in pot experiments during the cool season (28°C) and in field trials during the hot season (35°C). Both strains were efficient in reducing M. mayaguensis and other species of Meloidogyne populations (Duponnois et al., 1995). Duponnois et al. (2001) investigated the effects of organic amendments on the interactions between A. oligospora and M. mayaguensis parasitizing tomato plants.
