Ron, unless this is a very strange member of the genus, these nematodes are
not interested in plant tissue. There is a close relative under test in
Europe against slugs and snails, and again, this one is no threat to plants.

If the ants that are bothering you are the little fire ant - Wasmannia (the
one that is very tiny but easily seen in quantity as little moving russet
patches between stored pots or under tree bark [or almost anywhere else in
my garden where they drop off trees onto me while I work]) - the nematode
probably won't help much since they are probably a passive soil inhabiting
type that latches onto a passing prey but does not go hunting them down.

If you have the imported or the native fire ant, these might help, although
I don't remember hearing about them for this purpose. Fire ants, by the way
will slaughter your plants if the mood takes them. I'm not sure how they are
with monocots, but they strip the bark and conducting tissue right off
dicots when they once start in on them. If you use the nematode, please
keep us (me) posted. Derek

I don't know whether I picked up the reference from
this group or from somewhere else, but the following publication is a nice
introduction to biocontrol (and makes it clear that Heterorhabditis has not been
found successful against ants)
Try University of Florida sites for some stuff on
fireant control - they have a great creature from South America under test that
eventually takes the head right off the ants. It couldn't happen to a nicer

Derek is right....

I recently "released" 20 million predator nematodes into my plant pots and on my property...

It didnt do jack!

I would not expect an immediate effect from a biological control. "Recently"? Perhaps the nematodes died
while you were counting them :<))

Thanks Derek, I will be trying the nematodes on some of my potted Bonsai
trees, where the bottoms of the pots are ant haven. I don't know if I should
experiment on the Amorphs.I'll keep you posted if I see results. Ron

Dear All,

There were some mails about nematodes in
Amorphophallus. Today I received Amorphophallus yunnanensis and A.
asterostigmatus from Thailand (and some gingers...) There were some holes on the
tuber, but they are dried off now.
They could be nematodes as well, but I think when
we grow Amos in pots there are small risk to have a nematode infection. Our
garden soil is allready infected by nematodes, but it is not serious. As I was
mailing with a Dutch Zantedeschia breeder he told me that the biggest problem is
with Erwinia carotovora subsp. carotovora. This is an anaerob bacteria
which eats pectine (this material sticks the plant cells to eachother) and
becouse the wet and anaerob enviroment the tubers start to rot with a
distgusting smell (it is worse than the Dracunculus's). As I know the
nematodes and the Erwinias symthomes are very similar, so I would like to point
out that it can be an Erwinia rot as well as nematodes. To be sure is it
nematodes or Erwinia is to get some rasped tissue from the meeting point of
healthy and rotten parts and see if there is any nematodes.

As I'm not a Plant Protection Consulting
Engineer (yet) any professional help or advice is very wellcome on this
