Mosquitoes are one of the world’s most hated pests. Not only can they ruin otherwise perfectly comfortable summer evenings, they can also transmit deadly diseases. So why would anyone want to establish a mosquito farm? Through a series of trials, scientists have discovered that releasing genetically modified mosquitoes into certain areas significantly lowers the population of disease-carrying mosquitoes.
For example, one such project involves injecting a special bacteria into captive-bred male mosquitoes. The males are then released and pass the bacteria on to the females that they mate with. The bacteria inhibits the spread of the Zika virus and also sterilizes the females so that they cannot reproduce. In addition to Zika, this strategy could be used to target diseases like malaria and dengue fever.
