I THINK you're misreading the abstract (1): my reaading is that it's
talking about mosquitoes restricted to human blood as the sole source of
energy, vs those that have a sugar supply available -- not blood rich in
vs denuded of sugar:

If so, CR doesn't play into it at all, at all -- tho mosquito "ON"
apparently does.
