(A) The ability of larvae to escape from a spot of intense blue light in 5 s was assessed. Immunostaining showing that photoreceptors are ablated in BL > GMR-hid; shits third-instar larvae. Arrows indicate Bolwig's nerve and developing adult photoreceptor projection (APP), labeled with anti-chaoptin, in controls and residual staining in BL > GMR-hid; shits.
(B) Percentage of animals avoiding the blue light (±SEM). There were no significant differences between genotypes as tested with a Kruskal-Wallis test followed by a Dunn's multiple comparison. An average of 43 animals was tested for each genotype.
