Effective lethal phase of lopo¹. Eggs of wild-type Canton S (bold line), lopo¹ (hatched line), and a lopo¹ revertant lopo^1R47 (dotted line) were collected on apple juice plates and staged accordingly. The graph shows the percentage of surviving individuals at various stages of development (L1, first larval instar; L3, third larval instar). The effective lethal phase is during late third instar and early pupation. Thirty percent of lopo¹ larvae enter pupation but never reach adulthood. The revertant lopo^1R47 shows a wild-type developmental profile.
