Abstract
It was aimed to evaluate the influence of fungicides utilized in cucumber on the development of the aphid Aphis gossypii Glover under greenhouse conditions. The experimental design was completely randomized with four treatments and 45 replicates, being each plot consisting of a first instar nymph coming from an apterous female in early reproductive period. The fungicides utilized and their respective dosages at g i.a.L-1 were 800 PM sulphur (1.6), 800 PM mancozeb (1.6) and 840 PM copper oxichloride (1.5). The control was made up of water only. The products did not influence the median time of life in each instar and the nymphal stage, being respectively 1 and 4 days. Copper oxychloride and mancozeb increased the median time of life in days and the total life cycle of the adult stage of this species.
