Genetically modified genes that can be safely controlled

So, you’ve genetically engineered a malaria-resistant mosquito, now what? How many mosquitos would you need to replace the disease-carrying wild type? What is the most effective distribution pattern? How could you stop a premature release of the engineered mosquitos? Releasing genetically engineered organisms into an environment without knowing the answers to …
