Expression of ci3m.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL471B results in expansion of the wing disc in the wing blade region, with the anterior and posterior compartments being equally affected. Percentage embryonic lethality in lines expressing ciScer\UAS.cPa under the control of various Scer\GAL4 driver lines: 25% (Scer\GAL4e22c driver), 55% (Scer\GAL4ptc-559.1 driver) and 17% (Scer\GAL4en-e16E driver). Percentage larval/pupal lethality in lines expressing ciScer\UAS.cPa under the control of Scer\GAL471B : 58%.
