ProceedingsSummary: El acaro verde de la yuca (Mononychellus tanajoa) es actualmente una de las plagas mas importantes de la yuca en Africa. Se inicio la exploracion para enemigos naturales eficientes de esta plaga en Brasil a comienzos de 1988, mediante un convenio entre el Programa de Control Biologico en Africa/International Institute of Tropical Agriculture y la Empresa Brasileira de Pesquisa Agropecuaria (EMBRAPA). El trabajo consiste basicamente de 2 componentes principales: (1) la identificacion de areas con infestaciones sistematicamente bajas del acaro y la determinacion de enemigos naturales asociados con el acaro; (2) estimaciones de campo de la eficiencia de los enemigos naturales encontrados. Hasta ahora, los enemigos naturales mas diseminados han sido los acaros depredadores Amblyseius idaeus y Amblyseius limonicus, el primero en sitios mas secos y el segundo, en sitios mas humedos. (RA-CIAT)Summary: The cassava green mite (Mononychellus tanajoa (Bondar)) is today one of the most important pests of cassava in Africa. Explorations for efficient natural enemies of that pest were initiated in Brazil in the beginning of 1988 through an agreement between Africa-wide Biological Control Program/International Institute of Tropical Agriculture and the Empresa Brasileira de Pesquisa Agropecuaria (EMBRAPA). The work consists basically of 2 major components. The first refers to the identification of areas with consistently low infestations of the mite and determination of the natural enemies associated with it. The second refers to field estimations of the efficiency of the natural enemies found. Until now, the most widespread natural enemies detected were the predaceous mites Amblyseius idaeus (Denmark and Muma) and Amblyseius limonicus Garman and McGregor s.l., the former in drier and the latter in more humid places.
