81% of flies expressing Spn77BadsRNA.WIZ.Scer\UAS under the control of Scer\GAL4btl.PS are viable at 18[o]C, whereas all animals die before the adult stage if the animals also carry Spn77BaW7/+.
Hemizygotes show early lethality.
Spn77BaW7 is rescued by Spn77BaUASp.Tag:HA/Scer\GAL4Act.PU
Expression of Spn77BaScer\UAS.P\T.T:Ivir\HA1 under the control of Scer\GAL4hs.PB at 18[o]C allows some Spn77BaW7 animals to grow to the second instar stage. These animals have melanised trachea and in most cases die before reaching the third instar stage.
Expression of Spn77BaScer\UAS.P\T.T:Ivir\HA1 under the control of Scer\GAL4hs.PB at 22-25[o]C allows some Spn77BaW7 animals to survive to the third larval instar or pupal stages. These larvae and pupae have melanised trachea.
