Additional file 9.

Midgut Peristalsis in the Midgut from larvae homozygous for Dh31KG09001 . The movie shows the peristalsis within the anterior midgut junction region over the course of 60 seconds (total run time ~1.5 minute). The movie has been looped three times, and the rate increased to 4 frames per second from 2. The anterior midgut junction region is noted by the remains of the muscular tethers which come into view when the midgut rotates during play. As with Additional File 8, there is little motility in this region of the midgut when DH31 is not present.
