GOMEZ, Lucila; RODRIGUEZ, Mayra G  y  ENRIQUE, R. EFFECTIVINESS OF LACTUCA SATIVA USED AS A TRAP CROP OF Meloidogyne spp. IN THE VEGETABLE PRODUCTION UNDER SHELTER CONDITIONS. Rev. Protección Veg. [online]. 2009, vol.24, n.3, pp. 173-176. ISSN 2224-4697.

The aim of this work was to evaluate the effectiveness of lettuce (Lactuca sativa var Black Seeded Simpson) used as a trap crop of Meloidogyne spp. under shelter conditions. Lettuce plants were transplanted at a density of 49 plants per m² and they were harvested by extracting the entire root system from the soil 25-27 days later. Te initial and final nematode infestations were determined by a bioassay technique using tomato (Solanum lycopersicum var. Campbell-28). The results showed a reduction in 1,5 degree of the gall index in tomato roots, which suggested that the population of this nematode was reduced in the soil.

Palabras clave : Lactuca sativa; Meloidogyne spp; trap crop.
