Dear ACAROLOGY netters:

Some netters have observed that when you hit "reply" key in response to a
message posted on ACAROLOGY, the message will go to the individual who
posted that message, but not to everyone on the list.  This avoids sending
junk mails to people who do not need the particular response.  This system
is quite different from the operation in other lists such as entomo-l and
biocontrol-l, where the reply message was sent to everyone on the list when
you hit the "reply" button.  Many netters on entomol-l have complained
about receiving junk/personal message on the net beacuse some people abuse
the "reply" button.  In ACAROLOGY, that problem is being avoided.  However,
if you feel your reply to a message may be of general interest to many
people on the list, please send your reply to the
instead of the individual who posted the initial message.

Thank you very much for your attention.

Does anyone know of mitochondrial DNA primers that have proven successful

Subject: re: bee mites

In his book "A Hive of Bees" British naturalist John Crompton tells
of a plague of tracheal mites that infested bees first in the Isle of
Wight (it was first called Isle of Wight disease). The
problem started in 1904 and subsequently spread throughout Great
Britain, it took 20 years to identify the mite as the problem.  This
mite was identified as Acarapus woodi.  Is this the same as or
related to the varroa mite?  A cure was found which consisted of
saturating a pad with petrol, nitrobenzine, and saffrol oil and
applying it to the hive.  It was supposed to fumigate the mites, but
spare the bees.  Crompton feels that this mite, which does not crawl
about and must be transferred by direct contact must have come from
some other insect host sometime in the early 1900's, but at the time
he wrote the book, no alternate host had been discovered.

Dear netters:

Since its creation on 24 March 1995, over 100 acarologists from +20
countries have joined our ACAROLOGY list.  For a specialized group like
ours, the progress is quite good.  Please inform fellow acarologists who
are still not aware of this net and invite them to join.

You may find out the e-mail addresses of others on the ACAROLOGY list by
sending a "who acarology" command to "".  You will be
automatically sent a list of all members of the ACAROLOGY.

I have the following announcement:

The Third Symposium of the

European Association of Acarologists

First Announcement

The 3rd Symposium of the European Association of Acarologists, will be held
in Amsterdam, The Netherlands, after the previous meetings in Graz, Austria
(1988) and in Krynica, Poland (1992). The local organizing committee is
glad to announce that the 3rd Symposium will be held in the first week of
July (July 2-5), 1996. More information on the congress site and fee and on
hotel reservations will follow at the end of this year.

Main topics

The central theme of the Symposium will be: Ecology and Evolution in the
Acari. Emphasis will be given to phylogeny, evolutionary ecology and
population dynamics.

Local Organizing Committee

The local organizing committee consists of the following persons: Maurice
Sabelis (Chairman), Kees Davids, Leo van der Geest and Fred Veerman, all
from the University of Amsterdam. Administrative support will be given by
Mrs Tine Korzilius.

Lectures and Posters

The plenary morning sessions will be composed of lectures presented by
invited speakers. For the afternoon sessions, contributed paper sessions
are planned. There will be special sessions for those who intend to present
a poster.


A selection of the  papers presented at the Symposium will be published in
the Proceedings of the Symposium.

Dear colleagues,

It has now been confirmed that the Xth International Congress of Acarology
will be held in Canberra, Australia, from 6-10 July 1998. The host
institution is CSIRO Division of Entomology, and Congress sessions and

The International Institute of Entomology is offering the following short

Mites of glasshouses and nurseries: Identification, biology and control
September 21-23, 1995
London, UK

This intensive short course will provide an introduction to pest mites and
predatory mites of glasshouse/nursery crops and ornamentals. It will equip
those with an interest in glasshouse mites to identify mites commonly found
in glasshouses and nurseries, including both pest mites (e.g. spider mites,
tarsonemid mites, acarid mites etc.) and predatory mites (e.g. phytoseiid
mites).  Current information about the biology and control of common
species will be provided.

I am interested in specimens of Sarcoptes scabiei, both in collections
and from individals.  I work with an MSc student, Aileen McConnell, on a
project that aims to accurately describe Sarcoptes from different hosts
to look for morphological differences.  This is the preliminary phase of
a study which will also include molecular biological studies.

We work in northern Australia and have specimens from dogs and humans, as
well as from wombats in southern Australia.  We would like to examine as
many specimens as possible from as many hosts and geographic areas as

Does anyone know of museum or institutional collections that have
specimens of Sarcoptes scabiei?

Does anyone have specimens they would be prepared to donate, swap or sell
to us?  To be of use, we need an accurate host ID, geographic location
and specimens of good quality, preferably non-mounted.
