What are receivers between 118 and 162 MHz called?
Generically this is still called "VHF", though that also refers to Band II broadcast (aka FM) on 88-108 MHz, as well as air band, the 2m amateur band, and marine VHF (156-172 MHz). 

What application are you thinking of that covers this range? 

I would be searching for "VHF communications receivers".

It may be helpful to mention your geographic region. As far as I know, only the air band, the amateur 2m band, and the marine band are worldwide, there may be geographical limits on some other uses of these frequencies.
