According to a new study from the University of California, mosquitoes
are more likely to feed on cattle than on humans if they carry a specific
chromosomal rearrangement in their genome. This reduces their odds of
transmitting the malaria parasite. This reduces
their odds of transmitting the malaria parasite. Rates of malaria transmission
depend on whether mosquitoes bite humans or animals, and whether they rest
after that meal in an area where they will encounter pesticides. Using genetics
to better understand and track mosquito behavior can improve local control
strategies. This knowledge may also open novel avenues for stopping malaria's
spread, such as genetically modifying mosquitoes to prefer cattle over people.
I never look forward to the summer because I live in an area
where mosquitoes attack me from head to toe. After reading this article, it
made me wonder if my genome has an arrangement that makes the mosquitos for attached
to my blood than to other people. I found it interesting how a specific
chromosomal rearrangement of a genome could help reduce the odds of
transmitting malaria.
