This from 2016, but the bring up some genuine concerns about #GE #mosquitoes:

"This new evidence from the Cayman Islands highlights that #Oxitec is aware of a major flaw in its single-species, technological approach to eradicating disease-carrying mosquitoes. Oxitec makes clear that the release of the GE Asian Tiger mosquito Aedes albopictus might be needed if the release of the GE Aedes aegypti results in an increase of the numbers of #AsianTigerMosquitoes. Oxitec’s 2014 application to the Cayman Islands Department of Environment states, 'Should Aedes albopictus begin to occupy the Aedes aegypti niche upon reduction in their numbers, a concurrent operation will begin to reduce the numbers of Aedes albopictus'.

"The company has also previously hid information about the mosquito’s potential to survive. Company data noted that 15 to 18% of its GM mosquitoes survive when fed on cat food containing industrially farmed chicken, which contains the antibiotic tetracycline. Environmental groups have warned that this could lead to the survival and spread of large numbers of GM mosquitoes, when they encounter this common antibiotic in the environment e.g. in discarded takeaways or septic tanks."
