Pest Description
IDENTITY: Scientific name: Meloidogyne coffeicola
Lordello & Zamith, 1960
 Common name: A coffee root-knot nematode

NOTES ON TAXONOMY AND BIOLOGY: Female M. coffeicola have an oval cuticular perineal pattern with a low dorsal arch and faint striae. This root-knot nematode has sedentary endoparasitic habits. Second-stage juveniles (J2) penetrate host roots where they establish a specialized feeding site (giant cells) in the stele. As J2 develop, they cause root swellings and become swollen females, which protrude from the root surface with egg masses. (Lordello and Zamith, 1960).

GEOGRAPHICAL DISTRIBUTION:  This root-knot nematode is present only in Brazil.

HOSTS: Coffee (Coffea arabica) is the only agronomic crop parasitized by this root-knot nematode. The nematode has also been detected on native plants such as Eupatorium pauciflorum and Psychotria nitidula.

CROP LOSSES: Severe decline and dieback of coffee trees are associated with nematode infections (Campos, et al., 1990).

MEANS OF MOVEMENT AND DISPERSAL: Through root material, soil debris and by poorly sanitized bare root propagative plant material.

RATING: (M) Taking into consideration the economic damage this nematode causes on a perennial crop, this nematode was given a moderate priority rating.
