Population dynamics of nematodes in four peach palm varieties (Bactris gasipaes Kunth).
Agronomía Mesoamericana: Vol. 15, Issue 1 (January-June)
were made each trimester during the first year of plant
development in soils and roots of four varieties of peach palm.
Three of those varieties were spineless (Diamante-1, 10 and
20) and one had spines (Utilis-Tucurrique). The study was
carried out in Guápiles, Costa Rica. The population densities
of nematodes found in roots and soil were low and were not
considered of economic importance, but they had a wide
distribution. The following species were found in the roots:
Helicontylenchus spp was the most common, present in 100%
of the plants in Diamantes -1 and Diamantes-20; 90% in
Diamantes-10 and 85% in Utilis–Tucurrique. Tylenchus sp.,
Pratylenchus ssp., Criconemella spp. and Boleodorus sp. were
also found in still lower densities. In soil samples those species
were also found plus Ditylenchus sp. and Meloidogine sp.
