Verily,
the science division of Google, is conducting a field study of a plan
to rid Silicon Valley of yellow fever mosquitoes -which can also carry
dengue fever, malaria, and Zika. It involves releasing 20 millions more mosquitoes.
Verily is working with Fresno’s Consolidated
Mosquito Abatement District to release 1 million male mosquitoes every
week for 20 weeks, starting now. These mosquitoes have been rendered
essentially sterile by infection with a bacteria called Wolbachia
pipientis, which naturally colonizes mosquitoes and other insects in the
wild. In time, if the local females continue to mate with the sterile
males, the population should drop. The effort will ramp up to the full 1
million mosquito capacity over the next week, Kathleen Parkes, a Verily
spokesperson, told The Verge in an email.
This wouldn't
work in a species where a female mates with multiple partners before
laying eggs, but apparently mosquitoes aren't like that. Of course, the
first question is, what could possibly go wrong? It's not like we
haven't tried "fixing" our environment by introducing new creatures who
became invasive, and in this case, it's both mosquitoes and bacteria. Of
course, the yellow fever mosquitoes are invasive already, but introducing
one critter to take care of another critter
has gone wrong before. The second thought one has is sympathy for the poor grad student who had to sort millions of male mosquitoes from the females.
