Mosquitoes have an Achilles heel in their genes

Summer has only just begun and now, can’t you bear mosquitoes ruining your evenings? The researchers may have found a new solution to your problem. A genetic Achilles heel that would prevent disease-carrying mosquitoes from reproducing.

Eliminates mosquitoes while preserving other insects

Researchers have already developed some means of control. Recently, they started to release sterile male mosquitoes so that their mating with females present in nature does not produce offspring. But, “In the current context, the mosquito problem is only getting worse”comments Naoki Yamanaka, entomologist, in a press release. “Depending on a single tool to control populations would be unwise. »

What the researchers hope to do here is develop chemicals that can specifically block the three identified ecdysone transporters in mosquitoes. This is enough to prevent them from maturing and thus reproducing. These chemicals, on the other hand, would have no effect on other insects like the bees that they would still have a protein – in fact, the most essential, according to the researchers’ list – to deliver the hormone to their cells.
