Abstract/Description
Two bean cv. were exposed to known levels of attack of nymphs and adults of Empoasca kraemeri for 14-day periods at different growth stages. On av., Diacol-Calima and EMP 81 suffered a yield loss of 16.5 and 14.6 kg/ha, resp., per insect/leaf/14-day period. A study of the insect complex attacking fruiting structures of beans was carried out at CIAT-Palmira. It was found that Cydia fabivora and Epinotia aporema attack physiologically mature pods. The biology of the slug Vaginulus plebeius and of Zabrotes subfasciatus on beans was also studied. (CIAT)
Se expusieron 2 cv. de frijol a niveles conocidos de ataque de ninfas y adultos de Empoasca kraemeri durante periodos de 14 dias en diferentes estados de desarrollo. Diacol-Calima y EMP 81 en prom. sufrieron una perdida de rendimiento de 16.5 y 14.6 kg/ha, resp., por insecto/hoja/periodo de 14 dias. Se realizo en CIAT- Palmira un estudio del complejo de insectos que atacan las estructuras de fructificacion del frijol. Se encontro que Cydia fabivora y Epinotia aporema atacan las vainas fisiologicamente maduras. Tambien se estudio la biologia de la babosa Vaginulus plebeius y del gorgojo Zabrotes subfasciatus del frijol. (RA-CIAT)
