Flight characteristics

	Flight index, 22°C	WBF (Hz), 22°C	Flight index, 15°C	WBF (Hz), 15°C
IFI	3.9 ± 0.2 (66)	180 ± 5 (10)	1.9 ± 0.2 (52)	147 ± 1.7 (11)
IFI-7a, line 37A	3.6 ± 0.4 (46)	176 ± 3 (13)	1.3 ± 0.2 (66)*	143 ± 2.6 (13)
IFI-7a, line 86A	3.8 ± 0.3 (31)	176 ± 4 (12)	1.3 ± 0.2 (68)*	141 ± 1.4 (10)†

All values are mean ± SE. Numbers in parentheses indicate the number of flies tested. Line 37A and line 86A are independently generated, transgenic IFI-7a lines.
