Fig. 3. Timing of the commencement of ecdysis in larvae and pupae decapitated at
various times after injection of 200 pmol of ecdysis-triggering hormone (ETH).
Animals were injected with ETH (at 0 min) and decapitated at the times listed
on the y-axis (indicated by white arrowheads). Control larvae
(C) were not decapitated. Animals decapitated 10 min after ETH
injection did not ecdyse (`No ecdysis'), which is shown by a broken bar. Bars
are mean times + S.E.M. Sample sizes are indicated in parentheses. Letters
represent significant differences compared with controls within groups
(P<0.001), as determined by analysis of variance using the Tukey
test for differences (
=0.05).
