In an Effort to Limit Transmission of the Zika Virus,scientists

question 77

Multiple Choice

In an effort to limit transmission of the Zika virus,scientists have genetically modified the Aedes mosquito.  Evaluate the statements below and determine which describes the most plausible method to minimize disease.

• A)Male Aedes mosquitoes are genetically modified to have a "lethality" gene.  They are raised in the lab being fed with the antidote tetracycline.Once released into the wild,they mate with females and the offspring,without access to tetracycline,die before reproducing.
• B)Male Aedes mosquitoes are genetically modified to contain a gene that codes for a bacterial toxin.Once released into the wild they die before they are able to mate with females.
• C)Male Aedes mosquitoes are genetically modified to be temperature-sensitive mutants.  They are raised in the lab with air-conditioning,but once released into the wild,the heat and humidity in tropical climates causes their enzymes to denature,killing them before they can reproduce.
• D)Male Aedes mosquitoes are genetically modified to produce a protein that mimics the action of DEET in insect repellants.  The males mate with females and during the mating they pass the protein to the female and both mosquitoes are killed in the process.
