El objetivo del presente trabajo fue identificar los géneros de nematodos fitoparásitos asociados al cultivo de café Coffea arabica L. en el distrito de Cuispes, Bongará, Amazonas. Se colectaron al azar muestras de suelo del cultivo y de raíces de plantas de café en 58 parcelas. Las muestras de suelo y raíces se procesaron mediante el método de Baermann modificado en bandeja, utilizando 50 cc de suelo y 5 g de raíces. Se comparó la relación de los cuatro principales géneros de nematodos fitoparásitos, con la altitud (msnm), textura del suelo, porcentaje de arena, arcilla, materia orgánica y pH del suelo, mediante la correlación de Pearson con el programa IBM SPSS STATISTICS 21. La textura se determinó con el método de Bouyoucus, el porcentaje de materia orgánica con método de Walkley & Black y el pH de suelo mediante un potenciómetro relación 1:1 soluto solvente. Se ...

The present study aimed to identify the main genera of plant parasitic nematodes associated with the pineapple crop (Ananas comosus) and their respective percentages of occurrence (frequencies) and average population densities. Soil and root samples were collected from twenty eight pineapple fields in the province of Rodríguez de Mendoza, located between 1796 and 1936 meters above sea level. Sample were processed in duplicate by the method of modified Baerman on tray, using 50 cc. of soil and 5 g of root. In soil samples, eleven genera of plant parasitic nematodes associated with pineapple crop were identified. The genus Helicotylenchus was found in all evaluated fields and presented higher population averages in soil and root samples (24.5 and 3.9 respectively). This work is the first study to identify plant parasitic nematodes in pineapple cultivation in the department of Amazonas and...
