Se discuten y describen los danos y problemas causados por los acaros verdes (Mononychellus spp.) y el piojo harinoso de la yuca (Phenacoccus spp.) en las Americas. Se da una lista de 32 depredadores y parasitos de los acaros de la yuca en el neotropico. Esta lista incluye, entre otros, 16 acaros depredadores de la familia Phytoseiidae y varias especies de coleopteros de los generos Oligota y Stethorus. Se revisan los trabajos que se han realizado para controlar Mononychellus spp. usando estos depredadores. En relacion con el piojo harinoso se han registrado 25 parasitos en Phenacoccus gossypii, P. herreni y P. manihoti en las Americas. De estos, 21 pertenecen a la familia Encyrtidae e incluyen los generos Anagyrus, Apoanagyrus, Aenasius y Acerophaga. Recientemente se identifico el hongo patogeno Cladosporium sp. parasitando a P. herreni en Colombia y en Brasil. Tambien se han registrado 43 depredadores en las especies de Phenacoccus arriba mencionadas. Se analiza la situacion de P. gossypii y P. herreni puesto que representan problemas y modos de ataque diferentes y se discute su control biologico. Un problema con el complejo de enemigos naturales del piojo harinoso es la presencia de varios hiperparasitos que reducen las poblaciones de los enemigos naturales. Puesto que P. herreni es una plaga de importancia economica, la determinacion de su centro de origen es crucial para la identificacion de sus enemigos naturales mas eficaces. (CIAT) spa
Damage and problems caused by green spider mites (Mononychellus spp.) and cassava mealybugs (Phenacoccus spp.) in the Americas are discussed. A list of 32 predators and parasites of cassava mites in the neotropics is given. This list includes, among others, 16 predator mites of the phytoseiidae family and various coleopteran species of the genera Oligota and Stethorus. Work carried out to control Mononychellus spp. using these predators is reviewed. Regarding the mealybug, 25 parasites have been recorded in Phenacoccus gossypii, P. herreni, and P. manihoti in the Americas. Of these, 21 belong to the Encyrtidae family and include the Anagyrus, Apoanagyrus, Aenasius, and Acerophaga genera. The pathogenic fungus Cladosporium sp. was recently identified parasitizing P. herreni in Colombia and in Brazil. Forty-three predators of the Phenacoccus spp. previously mentioned have also been recorded. The situation of P. gossypii and P. herreni is analyzed since they present different problems and forms of attack; their biological control is discussed. A problem with the complex of natural enemies of the mealybug is the presence of varioushyperparasites which reduce the populations of natural enemies. Since P. herreni is an economically important pest, the determination of its center of origin is important for the identification of its most efficient natural enemies. (CIAT) eng
