As we continue to create mosquitos that are more and more resistant to anti-malarial agents, this news is really fantastic. I just hope that the environments that the Nile tilapia are entering are also kept in a good balance.

Another point raised by Joanne Greenfield of the WHO is also important... We may not be able to have such fish in areas where there is such shallow water. Still, the numbers of mosquitos reproducing in large bodies is probably greater than that of small pools. I think that this has at least a way of addressing the problem, which may also be more cost effective in the long run...
