When tamγ125.Scer\UAS is constitutively expressed under the control of Scer\GAL4444, some cuticular defects are apparent in the pupa, including the lack of several macrochaetae. When tamγ125.Scer\UAS is expressed under the control of Scer\GAL4hs.PB and subjected to heatshock pulses, no lethality is observed. However defects in the cuticularized structures of the emerging adults, including the eye, notum, wing and leg, that become more apparent and frequent as the severity of the heat-shock treatment increases. Abnormalities in the number and position of some bristles are apparent in the eye. Several alterations are seen in the notum, including loss of macrochaetae, disruptions in the pattern of the bristles are also frequently detected along the wing margin.
