Expression of the P{EP} insertions in the "EP1121" line (this line contains 2 insertions P{EP}EP1121aEP1121a and P{EP}Eip75BEP1121b) under the control of Scer\GAL4sca-537.4 results in too many or too few scutellar macrochaetae. Sensory organs with no socket, one shaft and one sheath cell and one socket and two shafts are seen.
The phenotype caused by expression of the P{EP} insertions in the "EP1121" line (this line contains 2 insertions P{EP}EP1121aEP1121a and P{EP}Eip75BEP1121b) under the control of Scer\GAL4sca-537.4 is not affected by N55e11 or HE21.
