Meloidogyne mayaguensis Rammah y Hirschmann, is an important pest in tropical and subtropical countries, because it affects in natural way more than 30 different species like guava (Psidium guajava), coffee (Coffea spp.), vegetables, ornamental plants and weeds. Its distribution has been very fast due to anthropogenic factors, and the highest concern about this species is its capacity to infest and reproduce on resistant plants to Meloidogyne spp. This species has a high variability in its perineal pattern morphology; thus the use of complementary elements like the offered by esterase profile is recommended. This specie has been found in mixed population with Meloidogyne incognita, Meloidogyne arenaria and Meloidogyne javanica, making more complex its diagnosis and management. Among the measurements to diminish its negative effect are the implementation of internal quarantine measures and the use of Cadusafos and Abermectine with variable results. In the same way, different research teams from Africa and America have evaluated extracts from Crotalaria spp., biological control agents (Arthrobotrys spp.), among other tactics. M. mayaguensis has been considered one of the most dangerous species of this genus. Its detection, right identification and contention in the areas in which it is found constitute one of the most important challenges for the sanitary authorities in the countries when the species has been reported. The opportune information and the effective training of the staff involved in the phytosanitary area represent a vital element for facing this emergent pest.
