Insertion of a P{PdL} element.
PdL14B1PdL14B1 homozygosity, or expression during development under the combined control of Tn10\tetRAct5C.T:Hsim\VP16 and doxycycline treatment, results in 100% lethality. Expression only during adulthood under the combined control of Tn10\tetRAct5C.T:Hsim\VP16 and doxycycline leads to a 21 to 32% decrease in life span compared to controls (without doxycycline).
