:tna1/tna5 larvae do not have melanotic tumors, nor are they larger in size than wild type.
65% of tna1/tna5 animals reach third instar larval stage, but only 41% pupate, and only 8% of the expected number reach pharate stage. No tna1/tna5 animals eclose as adults. The tna1/tna5 third instar larvae that fail to pupate often survive long after the pupation of their heterozygous siblings. The lifespan of some of the tna1/tna5 larvae extends to at least two weeks. In contrast to wild-type late stage third instar larvae, tna1/tna5 continue feeding.
