Abstract
As the centrifugal field increases, the size of Drosophila melonogaster larvae becomes limited and the growth rate decreases. The ratio of experimental to control growth rates was approximately equal to 1.3 - 2.7 x 10-4 g at ranges from 1000 to 4000 times gravity where g is the centrifugal field in units of the Earth''s gravity. An explanation for this relationship is proposed. Methods for culturing the larvae in a centrifuge and for recording their growth are described.
