Although the details are not fully understood, says Dr Montell, once female mosquitoes have mated a few times, they become less receptive to doing so again.

蒙特尔博士说，虽然细节还不完全清楚，但雌性蚊子一旦交配了几次，它们就不太愿意再次进行交配。

There is more work to do before field trials, says Dr Montell. But having established the principle, he is excited to see where the work might lead.

蒙特尔博士说，在实地试验之前还有更多的工作要做。但既然已经确立了原理，他很高兴看到这项工作的发展方向。
