Florida District Considers Releasing GMO Mosquitos After Cayman Islands Experiment (accuweather.com)

It's already underway just 364 miles south of Florida, according to the Associated Press. "The first wave of genetically modified mosquitoes were released Wednesday in the Cayman Islands as part of a new effort to control the insect that spreads Zika and other viruses," according to an article shared by Slashdot reader Okian Warrior: Genetically altered male mosquitoes, which don't bite but are expected to mate with females to produce offspring that die before reaching adulthood, were released in the West Bay area of Grand Cayman Island, according to a joint statement from the Cayman Islands Mosquito Research and Control Unit and British biotech firm Oxitec.
"What could possibly go wrong?" asks The Atlantic, citing history's great pest-control fails in Hawaii and Australia. But a similar release is already being considered in the Florida Keys, though Accuweather reports it apparently depends on the results of a November referendum which could also "affect the likelihood of Oxitec trials taking place in other parts of the United States."

Short-Lived Trial

Unless the released mosquitoes are replenished, their offspring will not perpetuate the cycle and so this trial won't last long. I'm not sure how plausible this would be, but it would be much better to release modified mosquitoes who's offspring are all male. This would then eradicate this species of mosquito.

Re:Why not use irradiated sterile mosquito

Because they are not sexy enough. Seriously. The female mosquitos do not want to mate with them, so they don't make much impact.

But what I'm curious about is why don't they use the GMO mosquitos that only have male descendents. That would quickly bring the species to extinction.

Unexpected Side Effects

My city drops larvicide down all the storm sewers three times a year in order to prevent West Nile Virus. (We've had no cases here and no positive tests in mosquitoes either this year.) So the bugs are gone and the job is done. But the flies are the worst they have been in at least 12 yeast (I can't say any further because I've only lived in this house for 12 years). The problem is that there are no predators in my suburb to eat flying insects anymore. Before the city started dropping the larvicide down the storm sewers there were plenty of swifts, purple martins, bats, and other flying animals that would eat insects. There was only parcel of land where some swifts managed to live until a last year when houses started being built on it. Now none of those animals exist in the suburb. The city could have encouraged more of those birds and bats to thrive here by giving away homes for them. It would have been cheaper in the long run instead of having to apply chemicals three times a year, every year.

Now we are seeing parts of the city where insect populations are getting out of control because there are no predators around. The city has to respond with chemicals because that's the only response left to them. The ecosystem is much more complex than what you think, even if you think it's complex. This plan isn't just taking out a particular insect. It has a purpose in the web or else it would exist.
