Dear colleagues
It is pleasure for me to inform you that I have finished a new
computer
program devoted to calculate probit analyses. Demo is available on
http://embakr.tripod.com/ldpline.htm .Any comment concerning
it well be
appreciated.
Also if any one has a proposal in computer programming and need programmer
I
am welling to cooperate with him.
Best regards
Your sincerely
Ehab

Dear Acarologists and Associated
I have received many helpful hints about this book. Some people even
offered
to copy it for us. Wow!!! Thanks again for all your helpful hints.
The book
seems to be at many institute libraries and here in Switzerland we
can
borrow the book from an acarologist to copy it.
I have however two interesting additions concerning the book:
The book is very useful for its discussions on the biology/ecology
of various species of stored product mites. As a guide for identification,
it is not so useful any more. The taxonomy is outdated, keys
are
incomplete, and illustrations are not up to current standards.
Also, many
species which are restricted to warmer climates are not included.
All the best - Barry

Dear Prof. O'Connor
I've received many mails about the requested book, you're the only
one with
critical remarks. The book seems to be stationed at different librarys,
probably even here at the University in Zuerich, so the easiest alternative
is to borrow it and copy it. I'd like to know if there is any modern
alternative to the one I've been looking for. Thanks in advance for
your
help. Marcus
Hi Marcus - The only more recent general treatment of stored product
mites
that I am aware of is the one produced by the US government (published
in
1991). The reference is as follows:
Gorham, J. R. (ed.). 1991. Insect and mite pests in food: an illustrated
key. US Department of Agriculture, Agriculture Handbook No. 655
(2 vols.).
Washington, D.C. 767pp.
The chapter on mites was written by Robert Smiley. This work consists
of
keys only. The keys are illustrated, and there are additional
illustrations of mites and some other groups at the end of the work.
I
still recommend the Hughes book for the biological/ecological information
in it (this book is the major reference cited in Smiley's chapter above).
Because the taxonomic problems still exist for numerous groups, this
more
recent key isn't much help there, particularly at the species level.
He
also follows Hughes in only recognizing "Caloglyphus" (a very paraphyletic
concept), rather than separating Cosmoglyphus and Neoacotyledon as
have
been done by most workers.
I guess my advise would be to get the Hughes book, but be aware of
its problems. If you have problem species to identify, I'd be
happy to
help.
All the best - Barry

Dear Mr. Prasad
I've tried several book shops, like Amazon.com and abe.com but without
luck.
The only possibility is to get it from an University library and to
copy it
manually. My question is, can you supply us with the book and if yes
how
much does that cost us. Thank you for your help

I've asked our boss, we have no more money on our literature account
for
this year and next year our literature account (among others) will
be
reduced (moneywise), so there is no chance for me to buy this book.
if
anyone else is interested, go ahed... Good luck!
A big thanks to all who tried to help and who have helped.

Dear all
IÆll be appreciated if any one could tell me any information
about the mode
and site of action of acaricides in mites and if it as the same in
insects
or not.
Thanks in advance.

Hello everybody,
I was approached because of ca. 1mm diameter necroses on orchid leaves,
caused presumably by some animals of the nursery substrate. I found
many
Oribatids in it (mostly Eremaeidae): does anyone know, whether Oribatids
or
specifically Eremaeida spp. may feed on Orchid leaves; any
idea, who else might like Orchid leaves? Thanks a lot!
Sincerely

Hi Hartmut,
Australian rainforests have many foliar Oribatida (although no Eremaeidae
that I've seen) and some of these are found in necrotic areas feeding
on
the dead tissue and associated microbes. There are some Indian
papers
about oribatids feeding on cabbage and the like, but I suspect that
these
also are cases of detritivory and microbivory. Tydeids also will
feed on
leaf spot fungi and could be mistakenly assumed to be herbivores.
Except
for some acarids (e.g. Tyrophagus feeding on seedlings), I don't know
of
any proven instances of oribatids (s.l.) feeding on green leaves, and
I'd
be interested if anyone thinks they have a good record.
There is a tenuipalpid pest of orchids, Tenuipalpus pacificus Baker,
that
causes blotches and necrotic spots. It has been reported from
glasshouse
orchids worldwide, including from Germany.
Cheers,
Dave

Dear Hartmut,
In the Netherlands we have some experience with plant feeding Oribatida.
Attached is a small note from me published in the Annual Report 1997

Dear Hartmut,
In an old German textbook: Pape, H., Krankheiten und Schädlinge
der Zierpflanzen, 5th ed 1964, oribatids are mentioned as feeding on orchid
flowers and on leaves of Anthurium. In both cases Galumna spp. But I have
not found any reports (when searching CAB Abstracts from the 70ties on)
confirming these observations.
However the family Galumnatidae is interesting as it harbours the (leaf-mining)
waterhyacinth mite, Orthogalumna terebrantis, which is used for biological
control of Eichhornia crassipes in many parts of the world.

Good evening !
Dont forget the paper of H.A DENMARK & J.P.WOODRING : "Feedind habits
of
Hemileius new species (Acari : Cryptostigmata : Oribatulidae) on Florida
Orchids" published in The Florida Entomologist, 48 (1): 9-16 (1965).
Have an excellent week-end ! With my best regards.
