I've read about bacteria affecting the transmission capability of mosquitoes. For example:

Have there been any studies to show that the presence of certain viruses/viral diversity (rather than bacteria) has an effect on the tranmission of other viruses/pathogens?

There have been some studies looking at this, but not many. One is this study which reported an interaction between Aedes densovirus (AeDNV) and dengue virus (DENV) in Aedes albopictus: mosquitoes already infected with AeDNV were more resistant to infection with DENV, although DENV infection appeared to accelerate the replication of the existing AeDNV infection. A similar interaction was not seen with chikungunya virus (CHIKV).

In addition there are indirect interactions between pathogens of all kinds - viruses such as AeDNV which kill a high proportion of the mosquitoes they infect reduce the average survival and population density of the vector and therefore the ability of the local population to transmit disease (ref).
