In California they use a Mosquito fish (looks a lot like a non-fancy guppy)
to take care of the larvae. I'll look for the scientific name, but it's
commonly referred to as Mosquito fish and it's hardy. They use it in
ponds and water fountains in the San Francisco Bay area which gets some
decent frosts, but doesn't freeze ponds usually. You can also use feeder
guppies or regular cheap goldfish. I'll email the scientific name if I
find it. It sure beats using oil or kerosene. Garden centers also carry
something I think is called Mosquito dunks or doughnuts which serve the
same purpose but I don't know what they are made from.
On another note, can someone list some decent understandable Tissue Culture
books or magazine references? Thanks,
