Population dynamics of nematodes in four peach palm varieties (Bactris gasipaes Kunth).
Nematode countswere made each trimester during the first year of plantdevelopment in soils and roots of four varieties of peach palm.Three of those varieties were spineless (Diamante-1, 10 and20) and one had spines (Utilis-Tucurrique). The study wascarried out in Guápiles, Costa Rica. The population densitiesof nematodes found in roots and soil were low and were notconsidered of economic importance, but they had a widedistribution. 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% inDiamantes-10 and 85% in Utilis–Tucurrique. Tylenchus sp.,Pratylenchus ssp., Criconemella spp. and Boleodorus sp. werealso found in still lower densities. In soil samples those specieswere also found plus Ditylenchus sp. and Meloidogine sp.
