In: Tropical Pest ManagementSummary: Se evaluaron materiales para el mejoramiento de la yuca del International Institute of Tropical Agriculture (IITA) por resistencia al acaro verde de la yuca (AVY), Mononychellus tanajoa, en las estaciones de Chambesi y Kizimbani, Tanzania, donde fue alta la poblacion de AVY. En la estacion de Chambesi, 58 clones (15 por ciento) de los 377 evaluados en infestacion natural fueron determinados resistentes (clase 1 y 2) a AVY. En Zanzibar los clones resistentes al AVY, los cuales presentaron altos rendimientos, resistencia al AMD y de calidad aceptable al consumidor, se estan multiplicando para distribucion a los agricultores. (RA-CIAT)Summary: Cassava breeding materials from the International Institute of Tropical Agriculture (IITA) were evaluated for resistance to cassava green mite (CGM), Mononychellus tanajoa, at the Chambesi and Kizimbani Stations, Tanzania, where CGM population was high. At Chambesi Station, 58 clones (15 percent) of the 377 clones tested under natural infestation were rated resistant (classes 1 and 2) to CGM. In Zanzibar the CGM-resistant clones, which were high- yielding, resistant to CAMD and acceptable in consumer quality, are being multiplied for distribution to farmers. (AS)
