Resistencia al nematodo "Tylenchulus semipenetrans" en nuevos patrones híbridos de cítricos

Abstract

Tylenchulus semipenetrans es el principal nematodo fitoparásito que afecta a los cítricos en España. El uso de patrones resistentes al nematodo es un método de control efectivo, económico y no agresivo con el medio ambiente. No obstante, la existencia de biotipos o razas fisiológicas del nematodo puede limitar el uso de algunos de los patrones resistentes. En este artículo se presentan los resultados de una serie de estudios realizados para determinar los biotipos del nematodo más frecuentes en España; evaluar la respuesta de nuevos patrones híbridos de cítricos frente a T. semipenetrans en condiciones de invernadero, la respuesta de estos patrones en campo y las fluctuaciones estacionales de las densidades de población del nematodo. El único biotipo de T. semipenetrans detectado en las áreas citrícolas españolas ha sido el biotipo Mediterráneo. Se ha identificado resistencia a T. semipenetrans en ocho cruzamientos de mandarino cleopatra x P. trifoliata. Las fluctuaciones de las densidades de población del nematodo en las raíces mostraron que el número de huevos por gramo de raíz incrementaba considerablemente en primavera, mientras que el número de hembras solía hacerlo en verano.
