<br/><br/> Dry medical yeast level in larval diet of Mediterranean fruit fly was examined by increase and decrease two levels than the standard level to study the influence on the biological aspects of the different stages. The results concluded that the increase in the amount of yeast reflected by significant decrease in the days to pupation as will as the larval duration, number of pupae/ml, preoviposition and oviposition periods, insignificant increase in pupal size (length and width), adult emergence and significant increase in percentage or pupation, pupal weight. number of eggs/ female and percentage of egg hatch.
