Second-order derivative FTIR spectra of diapausing female Cx. pipiens. (a) Second-order derivative FTIR spectra of dsi-RNA treated female Cx. pipiens from Fig. 6a. (b) Overlapping second-order derivative FTIR spectra of mosquitoes enlarged for lipid absorption bands at 2920 and 2850 cm−1. (c) Derivative spectra centered at 1745 cm−1 for C=O stretch found in lipids (Fig. 5b). (d) Second-order derivative spectra centered at 1078 cm−1 for in-plane bending of COH found in glycogen.
