在D. M.在产卵后约70小时（25[degree]C）发生组织变化。在70小时的变化后，缺乏食物的幼虫可能在发育上有所加速。从朱红褐色幼虫身上完全去除食物的时期对眼睛色素的产生没有明显的影响。无论饥饿期是长是短，无论是在70小时变化之前还是之后，这都是正确的。幼虫部分饥饿，在一定条件下，大大增加了朱红褐蝇形成的眼色素量。对眼睛产生色素的这种“饥饿效应”最敏感的发育时期是在70小时变化之前不久。在有限的发育期内，即上述最敏感期，给予朱红褐色幼虫的食物量，会极大地影响一种被认为是特定的眼睛颜色激素[uppergum]+激素的产生。
In the development of larvae of D. m. an organizational change takes place at about 70 hours after egg laying (25[degree]C). Larvae deprived of food after the 70-hour change are probably somewhat accelerated in development. Periods of complete removal of food from vermilion brown larvae are without apparent effect on eye pigment production. This is true whether the starvation period be short or long and whether it comes before or after the 70-hour change. Partial starvation of larvae, under certain conditions, greatly increases the amount of eye pigment formed by vermilion brown flies. The period of development most sensitive to this "starvation effect" on pigment production by the eye lies shortly before the 70-hour change. The production of a supposedly specific eye color hormone, [upsilon]+ hormone, can be influenced greatly by the amount of food given to vermilion brown larvae during a limited period of development, the period of maximum sensitivity referred to above.
