the genetic tampering "science"

  Scientists at the University of California San Diego implanted the dengue immune proteins, called antibodies, into female mosquitoes.
  Antibodies are created naturally by the body and are what enables the immune system to destroy bacteria and viruses by itself without medical help.  But someone must become infected with, or exposed to, an illness before the body is able to develop them, which is risky with such a deadly disease.
  The researchers found putting human dengue antibodies into mosquitoes stopped the disease spreading among the insects.  And by engineering the genes of the insects to make sure those with the antibodies inside them were successful breeders, researchers said it would be possible to make this immunity spread through the wild population of the insects.  

Professor Omar Akbari, who led the study, said:  "Once the female mosquito takes in blood, the antibody is activated and expressed--that's the trigger.  The antibody is able to hinder the replication of the virus and prevent its dissemination throughout the mosquito, which then prevents its transmission to humans. It's a powerful approach.  It is fascinating that we now can transfer genes from the human immune system to confer immunity to mosquitoes."…
  Professor Alphey cautioned that a small mutation in the dengue virus would make it resistant to the antibody which the scientists used, thus able to spread again. 
"It’s just one antibody so you expect resistance to evolve fairly quickly.  This example only has one antibody in it.  So a small change in the virus would lead to resistance to that one antibody.”     https://www.dailymail.co.uk/health/article-7894859/Scientists-engineer-dengue-resistant-mosquitoes.html

  That suggestion has prompted a backlash from the company.  "We're not surprised by the results, but what we are surprised by are the speculations that the authors have made," Nathan Rose, head of scientific and regulatory affairs at Oxitec, told Science magazine.   https://www.livescience.com/genetically-modified-mosquitoes-create-hybrids.html
