I don't really know. As I said, it was something I read some previous
summer about the dunks and it convinced me not to use them. However I can
really find nothing useful about it now in the time I think it is worth
investing. I don't know if the story has disappeared because the original
story that I'm referring to did not make the distinction between the
different bacteria strains, if it was based on an in process study that
didn't pan out, if it has just been swept under the rug because everyone is
far more concerned about the diseases passed by mosquitoes than they are to
what may be only a minor impact on the environment, or what (however I am
noticing that being an environmentalist is about to take the same four
letter word status as liberal how holds).

The one thing that I do know is that I am happy that it motivated me to get
rosie reds and this year guppies. They are far more entertaining than a
floating chunk of dunk. I'm not saying what people should or should not
do.... I'm simply musing on line... I'm currently having my a$$ chewed off
in rec.ponds for similar musings so I'm getting a bit nervous about doing it
at all. DK

The article said Bt sub-species. Not likely talking about Bt-i.

I read a while back that there was concern about its toxicity to bees....
From what I can find now there is only one species of bees that it is
highly
toxic to. Others may suffer a shorter lifespan but not one that anyone
seems concerned about. It certainly seems the case that the cost/benefit
ratio is on the side of using it. I still like guppies better though...

regular Bt will kill any caterpillar. Bt israeli will only kill
mosquito
and midge
larvae. Ingrid

The worry is that not only do they kill mosquitoes but that they kill

small water gardens (barrel size). This year I put in 2 guppies which
I
will now have to bring in for the winter since they are tropical....
Anyone
want some guppies (now 3)?
