In the green peach aphid, Myzus persicae, sexual generations have been produced on a holidic diet, but fertile eggs have not been obtained so far. In this report we examined the effect of vitamins on the production of sexuals. When the vitamins in a synthetic diet were condensed 2-fold, larval mortality decreased and the ratio of males increased markedly compared to those parameters for insects fed the standard synthetic diet. A 4-fold increase in vitamin concentration resulted in a further increase of the proportion of males. When vitamins were condensed 8-fold, most larvae died. The higher the vitamin concentration, the lower the average fertility. But the number of adult males obtained on the vitamin-rich diet was about the same as than for males on the radish seedlings. Oviparac were only obtained with the diet containing 4-fold concentrated vitamins. These oviparac were mated with males obtained from the same diet and laid eggs, however, the eggs did not hatch.
