Very little chance the two varieties of mosquito carrying Zika will establish permanent populations in more northerly areas. I noticed that one single mosquito of this type was catalogued in Portland, Or, several years ago, but none since.
I disagree !
Last month there was confirmed 3 year observation of the Zika carrying mosquito Aedes aegypti breeding in a bird bath three blocks from the White House.
Furthermore , Aedes aegypti have been found and observed breeding in Connecticut . Culex quinquefasciatus

The GLobe and Mail found on July21/16 :
"Zika was found in Culex quinquefasciatus in the northeastern city of Recife, ground zero for the outbreak of fetal brain defects caused by the virus – and this species is 20 times more common there than Aedes aegypti, which until now has been identified as the main vector.
“It’s very bad news for Brazil,” said Constancia Ayres, the entomologist who conducted the research and who has been a lonely voice
insisting that it was risky to focus exclusively on Aedes aegypti as Brazil scrambled to respond to the Zika outbreak over the last year."
“We ( Brazil) have a national program for controlling Aedes – but we have nothing for Culex – so if Culex is an important vector then we have to start from zero.”
