    The main objective of this work was to investigate the ability of Aphis gossypii and Myzus persicae to transmit Cucumber mosaic virus (CMV) singly and mixed with two potyviruses (Papaya ringspot virus - type W, PRSV-W and Zucchini yellow mosaic virus, ZYMV), to zucchini squash plants (Cucurbita pepo). The results showed that the potyviruses in general were more efficiently transmitted by both species of aphids as compared to CMV. The transmission of PRSV-W, ZYMV and CMV separately was more efficient than in mixture.<br>O objetivo desse trabalho foi estudar a eficiĂȘncia de Aphis gossypii e Myzus persicae na transmissĂŁo do vĂ­rus do mosaico do pepino (Cucumber mosaic virus, CMV), isoladamente e em mistura com duas espĂ©cies de potyvirus (VĂ­rus do mosaico do mamoeiro = Papaya ringspot virus - type W, PRSV-W e VĂ­rus do mosaico amarelo da abobrinha = Zucchini yellow mosaic virus, ZYMV), para planta-testes de abobrinha de moita (Cucurbita pepo). Os dois potyvirus em geral foram transmitidos com mais eficiĂȘncia pelas duas espĂ©cies de afĂ­deos do que o CMV. A transmissĂŁo do PRSV-W, ZYMV e CMV, separadamente, foi mais eficiente do que em mistura
