The mean predicted physiological age of An. arabienis using NIRS

Chronological age	Virgin	Pre-gravid	1st oviposition	2nd oviposition
3 days old	1.08 ± 0.49	1.98 ± 0.28
5 days old	1.87 ± 0.46	2.05 ± 0.44	2.19 ± 0.39
8 days old	2.03 ± 0.40	2.13 ± 0.48	2.33 ± 0.30
11 days old	2.44 ± 0.34	2.5 ± 0.23	2.62 ± 0.45	2.6 ± 0.32
Average	2.085 ± 0.42	2.165 ± 0.36	2.38 ± 0.38	2.6 ± 0.32

The mean physiological ages were predicted from the cross-validation model developed using An. Arabiensis of different physiological status (Virgin-1.0, Pre-gravid=2.0, 1^st oviposition=3.0, 2^nd oviposition=4.0).
