Abstract
The spontaneous locomotor activity of young, middle-aged and old Droso phila melanogaster of both sexes has been videorecorded during three p arabolic flights separated by one-day intervals. Fast shifts between 0 g, 1 g and 1.8 g phases are obtained during parabolic flights. Result s showed that the activity scores were higher at 0 g during the first flight, but that this effect of microgravity was erased during the two next flights. It may be concluded that flies showed a transient form of reactivity to a new environment, i.e, to repeated rapid variations of gravity levels.
