a Cartoon representation of a dissected larva (pink) and a hemisegment highlighted by dashed red rectangle. The target muscle examined in (b–d) is shown in blue. Cartoon is generated with Biorender. b Quantification of MN4-Ib bouton number in non-ablated and Is ablated larvae in control, glia draper-II overexpression, and muscle draper-II overexpression backgrounds.

For (c, d), N (NMJs) = 14, 12, 12. e Cartoon representation of a dissected larva (pink) and a hemisegment highlighted by dashed red rectangle. The target muscle examined in (f–h) is shown in blue. Cartoon is generated with Biorender. f Quantification of MN6-Ib bouton number in non-ablated and Is ablated larvae in control, glia draper-II overexpression, and muscle draper-II overexpression backgrounds. Control (N = 19 and 19 NMJs), t(36) = 4.319, p = 0.0001, unpaired t test, two-tailed. Glia draper-II overexpression (N = 23 and 17 NMJs), t(38) = 1.626, p = 0.1122, unpaired t test, two-tailed.
