  • Genetically modified mosquitoes that cannot transmit malaria are one hope for battling the disease that still kills over one million people a year. But that plan faces some serious snags, according to UC Davis researchers who are suggesting an alternative strategy.

  • releasing into the wild mosquitoes genetically engineered to resist malaria
  • If the resistant mosquitoes breed and spread their genes through the population, malaria transmission should be shut down.
  • the malaria resistance genes available are not very effective
  • , there's no way to reliably push the genes through the population.
  • Transposons are essentially DNA parasites that snip themselves in or out of the genome under the right circumstances. Scientists can add a new gene into a transposon and use it to carry that DNA into the insect genome. But it's in the interest of that transposon to just get rid of the extra DNA,
  • a transposon that gives an advantage to mosquitoes that already carry genes to block malaria, so that those genes spread through the population by natural selection.

  • These mosquitoes are genetically engineered to kill — their own children.
  • The results, and other work elsewhere, could herald an age in which genetically modified insects will be used to help control agricultural pests and insect-borne diseases like dengue fever and malaria.
