In: In: NAFPP National Cassava Workshop (6, 1982, Umudike, Nigeria). ProceedingsSummary: Se revisan las estrategias utilizadas por el International Institute of Tropical Agriculture para controlar a Phenacoccus manihoti en yuca. El control biologico de la plaga ha sido exitoso con los depredadores introducidos Hyperaspis sp. y Scymnus sp. y el parasitoide Apoanagyrus lopezi. Se espera que el control biologico en combinacion con la resistencia de la planta hospedante reduzca los problemas de P. manihoti en Africa en el futuro. El mejoramiento genetico de la yuca esta enfocado hacia la incorporacion de una mayor densidad de pelos en la superficie de hojas de yuca jovenes y el desarrollo de clones glabros que mantengan a las poblaciones de P. manihoti a un bajo nivel. La antibiosis, por otra parte, parece ser efectiva en el clon 70453 en los expt. que se estan adelantando. (CIAT)Summary: Strategies used by the International Institute of Tropical Agriculture to control Phenacoccus manihoti attacking cassava are reviewed. Biological control of the pest has been successful with the introduced predators Hyperaspis sp. and Scymnus sp. and the parasitoid Apoanagyrus lopezi. It is expected that biological control in combination with host plant resistance will reduce P. manihoti problems in Africa in the future. Cassava breeding is aimed at incorporating higher hair density on the surface of young cassava leaves and the development of glabrous clones that keep P. manihoti populations at a low level. Antibiosis, on the other hand, appears to be effective in clone 70453 in on-going expt. (CIAT)
