Subject: Mite and mite egg case ID

I found numerous mite skins and an egg case on a basement door that
was covered with Aspergillus,  E. repens E. rubrum.  I have an SEM of
the egg case and partial mite bodies.  Could I e-mail this to someone for
ID? From a wall sample of Stachybotrys on drywall, I found several small
mites and a 300 micron mite that I am also curious about.(light

Someone had asked me if Pyemotes boylei is a valid name. As far as I know
it is and is the only pyemotid species established in Hawaii. Can someone
tell me if what I know is still true and if the name was synonymized with
P. tritici?

Subject:  XXI ICE Abstracts - last call

Dear participants

We thought it was completely clear, since August, 1996, when the abstract
session was placed on the homepage, but we were asked by several
participants if they are to submit abstracts in the case of presenting a
paper during the XXI ICE.

Have to present abstracts:
1. All Plenary Lectures;
2. All participants of the symposia of sessions 1 to 23 and also the
Special Session, with oral presentation;
3. All participants presenting papers as posters.

Item 16. of the abstracts page on the homepage (the same for the 2nd
announcement) says:

"16. Abstracts received after February 28th, 2000 will not be considered
for publication and for presentation in the oral or the poster sessions. In
this case, space on the session or plenary lectures abstracts volume will read
"The author did not send the abstract"
following the title of the presentation and the name of the author."

The deadline for submitting abstracts was postponed to March 10th.

Dear sir,

I am so delighted to write you this letter. I inform you that I am a student
in a high school of agriculture from Morocco.

I am previously preparing a thesis about the pesticide mite resistance,
more specifically in Tetranychidae.

So I ask you, if it is possible, to send me some documents about that.
That would be very helpful to me.

Subject:  John Conroy - Canadian water mite biologist

Dear Acarologists:

Below is the obituary of Dr. John Conroy, water mite biologist, who died
suddenly last month.  Dr. Conroy worked on the taxonomy and ecology of
western Canadian water mites.  He described new species of Hydrodroma,
Limnesia, Sperchon, Sperchonopsis, Lebertia, Arrenurus, Neoacarus, Piona,
Tiphys, Forelia, Pionopsis, Atractides, and Unionicola, and revised the
North American Neumania.  His ecological papers include surveys and
checklists of the water mites of western Canada including British Columbia,
studies of drift in stream-dwelling mites, and phenology of planktonic
Unionicola.  His industry and sense of humour will be missed.

[from the Winnipeg Free Press]


Suddenly on February 25, 2000 at the Health Sciences Centre, Professor John
C. Conroy (BSC, MSC, PhD) in his 61st year. Much loved husband of Mary
Conroy; father of David (Carol), Allan, and Alison (Don); granddad of Sean,
Sarah, and Eric. Predeceased by his parents, Judge Charlie and Mary Conroy;
and his brother Paddy Conroy. Also survived by
Grace Redmond, Michael Conroy, and Anne Coyle; brothers-in-law;
sisters-in-law; and many nephews and nieces.

John was born in Dublin, Ireland on July 27, 1939. He was educated at
Xavier's School, Clongowes Wood College, National University of Ireland
(Dublin), National University of Ireland (Galway), and the University of

John and Mary were married in Limerick on September 17, 1963 and
immigrated to Winnipeg to take up a post as a lecturer in Biology at United
College (University of Winnipeg). The couple briefly lived in Vancouver
before settling in Winnipeg to raise their family.

John was a dedicated professor, well respected by his colleagues, and much
loved by his students. For several years he presided as the Chief Marshall
of convocations at the University of Winnipeg. He was also President of UCD
in North America, a member of the Manitoba Entomological Society, Secretary
of the International Congress of Entomology, and a representative of the
Veterinary School of Saskatoon.

John was an active member of the community of St. Ignatius, acting as a
lector, co-ordinator, instructor of confirmation, and chair of the Parish
Pastoral Council and the Liturgy Committee. He was also active at various
levels in the Liberal Party.

Prayers will be held on Tuesday, February 29 at 7:30 p.m. at St. Ignatius
Church (Corydon and Stafford). Funeral service will be held on March 1 at
1:30 at St. Ignatius Church. Fr. Eric Jensen will celebrate the funeral
mass. In lieu of flowers, donations may be made to the University of
Winnipeg, in care of University Affairs. A scholarship in Entomology will be
set up in his name, The John Conroy Scholarship Fund, University of
Winnipeg, 515 Portage Ave., R3B 2E9. For more information please call

Subject:  extraction of soil microarthropods

I posed a question to the Acarology and the Collembola lists about two month
ago, to find proper extraction fluids for the Macfadyen canister extractor for soil
samples. Here is a long overdue summary of the many interesting responses I
received. Sorry for the long delay! Many thanks to all who responded!

In short, there is no simple solution to the problem. Several of the following
substances seem worth trying (especially benzoic acid, see the response of
Henning Petersen below), but there's no tested standard fluid. Discouraging, if we
imagine that the canister technique is still the most efficient method for the
extraction of soil microarthropods. Nobody out there to make a comparison of
fluids ...?

Following are the summarized messages, details omitted. Two mails with the
most detailed recipes are given in full length.


D.A. Crossley suggests to extract into water (plus detergent) but believes that
there's no difference in extraction efficiency between water and 70% ethyl alcohol.

Christian Kampichler also favours water (plus detergent plus glycerol) but
concedes to have to change the canisters in short intervals (daily?) to transfer the
extracted animals into ethanol.

Gordon Robertson uses water. He never had problems with fungal contamination
or interference between caught animals. This can be due to the presence of lead
weights in the canisters that may have toxic effects on both fungi and animals.

Gerd Weigmann uses picric acid (a 50% aqueous solution), and suggests to try a
5-10% solution of benzoic acid, or a 1% solution of Cu-sulphate.

Henning Petersen and Steve Coulson use benzoic acid solutions. See their
recipes below.

Hartmut Koehler and Ken Christiansen abandoned the cumbersome Macfadyen
apparatus completely. Ken Christiansen suggests to use polyethylene glycol.

Guy Vannier had the idea to use parafin oil, which has low density (0.56, allows
the animals to sink), is tasteless, odourless, translucent and cheap.


Steve Coulson wrote:

"<italic></color>We use benzoic acid with excellent results. Less toxic and less explosive

than picric acid! I tend to use a 100% solution but this can be diluted

considerable and the Collembola and mites are still rapidly killed. After

extraction I remove some of the benzoic acid solution and replace with 96%

alcohol to create an approximately 70% alcohol solution. After fitting a

lid to the vials, they are heated at 60 degrees C for a couple of hours to

encourage the Collembola to sink (they may need to be poked under with a

pencil etc.). I then add a few drops of glycerol and incubate at 60C

overnight. On the following day I remove the lids and evaporate the

alcohol etc. The animals are now stored in a thin film of glycerol and

will keep more or less indefinitely.

Henning Petersen wrote:

"<italic>I have worked with Macfadyen type extractors through many years and have

found that  both the "canister" type and the "funnel" type give

satisfactory high extraction efficiency (Petersen, H. 1978. Some

properties of two high-gradient extractors for soil microarthropods, and

an attempt to evaluate their extraction efficiency. Natura Jutlandica 20:

95 - 121).  At that time I used picric acid solution but because of the

carcinogenic nature I later replaced it with an aqueous, or rather thin

alcohol-, solution of benzoic acid.  Benzoic acid does not easily dissolve

in water. Therefore, it has first to be dissolved in 96% alcohol. After

addition of a few drops of detergent it can be diluted with water. Our

recipe here is: 15 g Benzoic acid is dissolved in 1 l 96% alcohol. 3 drops

of detergent (Nonidet) are added. This liquid is diluted with 4 l

distilled water. This liquid works well in spite of the alcohol content.

However, for the canister type extractor with little air between soil and

liquid surface it may be recommendable to try to reduce the alcohol

percentage as far as possible.

In order to make the hydrophobic animals sink into the liquid after

extraction so much 96% alcohol is added that an alcohol percentage of

about 70% is attained. Thereafter, we close the vials and put them in a

drying oven at 60 degrees C for about 24 hours. This treatment apparently

makes the cuticle wettable. It is advisable to check the vials for

specimens sticking to the walls.

Following up on the discussion of easy ways of counting specimens I use to

transfer the liquid with the extracted specimens to small petridishes (5

cm diameter) and add so much glycerol that the bottom will be covered

after evaporation of the extraction liquid. The evaporation is done in a

drying oven at 50 degrees C.  In glycerol the animals will remain at a

stable position in the petri dish and counting may be done systematically

using a grid below the dish. I use a specially constructed electronic

counter with 16 units  activated from a 4x4 keyboard. I can the count 16

species/groups at a time. In cases with many specimens in each grid field

I estimate a number for each field by counting by 10´s instead of by 1´s.

In fact, hundreds of individuals can be counted in few minutes, and I have

given up attempts to rationalize the counting process further based on for

instance counting sectors of the complete sample or using image processing

or the like in cases where several species or groups have to be
