Abstract
The loss of yield resulting from infestation with potato leafhoppers,Empoasca fabae (Harris), was measured in a group of potato selections (Solatium tuberosum subsp.tuberosum). For 6 years in which 300 different clones were tested, the average loss of yield was 39%. The correlation over clones between level of infestation and percent hopperburn equaled 0.56; between level of infestation and loss of yield 0.36; and between percent hopperburn and loss of yield 0.41. Each coefficient is significant at P=0.01.
Significant differences were found in levels of infestation and in percent hopperburn among the selections, but even those selections with the most resistant foliage had greatly reduced yields when infested. No selections were found that consistently produced a normal yield when infested with leafhoppers. The low level of infestation on the more resistant clones, however, may make chemical control at lower rates more effective.
Resumen
Las pérdidas en la cosecha causadas por el saltahojas de la papa,Empoasca fabae (Harris), fueron medidas en un grupo de selecciones de papa (Solarium tuberosum sub sp.tuberosum). Durante seis años en los cuales se probaron 300 clones diferentes, el promedio de perdida en la cosecha fue de 39%. La correlación de los clones entre niveles de infestación y porcentaje del daño de los saltahojas fue igual a 0.56; entre niveles de infestación y pérdidas en la cosecha fue 0.41. Cada uno de los coeficientes es significativo al nivel de P = 0.01.
Se encontraron diferencias significativas en los niveles de infestación y en el porcentaje de daño entre las selecciones pero, aquellas selecciones que tuvieron el follaje más resistente, tuvieron también las más grandes reducciones en la cosecha cuando fueron infestadas. No se encontró ninguna selección que produjera una cosecha normal cuando estuvo infestada con saltahojas. Los niveles bajos de infestación encontrados en los clones más resistentes, sin embargo, pueden reducir la frecuancia en la aplicación del control químico con mejores resultados.
