Values are averages±s.e.m.; n=10 for each group. Units are minutes or number, or mm, depending on the measurement.

(ns) P>0.05;

(*)

0.01<P<0.05;

(**)

P<0.01. Student's t-test.

§

Behaviors resembling ecdysis were not observed.

Period between the end of head eversion [ecdysis (for controls) or pre-ecdysis sweeps (for KO larvae)] and the end of body contractures.

††

Measured on pharate adults, from joint at the level of the neck; one prothoracic leg was measured per animal; n=23 per group.

‡‡

Measured on pharate adults, one wing easured per group. n=20 per group.
