Hi..i am a dermatologist at Mt. Sinai School of Medicine in NYC.  I am interested in looking at the relation of several human skin diseases to demodex folliculorum mites.  Do you know anyone who has isolated any antigenic proteins from these mites. Any help will be greatly appreciated.  Donald

Subject:  Marine Mites

I posted a couple of weeks ago about putative marine mites I observed on sponges.  I haven't received any response.  Any response would be welcome.

Meanwhile,  in speaking with my son's pediatrician yesterday, it came out that there is one beach, near a sewage outfall and a newly abandoned dump, where  quite a few people have reported picking up a rash.  The doctor says there is a "mite" out there.  I wondered, are there known to be such medically important marine mites?  Perhaps she was using "mite" in a less precise sense.

 In the early 80's we did some work on human demodicosis. Antigenic material was obtained by squashing the demodex nodules of goats, where tens- to hundreds of thousands of Demodex caprae can be isolated.
 Unfortunately all our effort with infection of uninfested jung goads, skin testing and lymphocyte transformation tests did not give any clear cut results.
Good luck

Dear acarologists,

A few years ago I "inherited" one large bottle of "Balsamo de Peru" (Merck, 1 Kg). A few days ago I decided to try it, to prepare a few slides of soil mites. I found that it is very dark brown! and I had
to quit promptly as the mites were hardly visible when covered with that dark stuff!
I have tried to find out some information on its usage, asking other members of our Department of Zoology, Universidad de Panama, but no one has used it nor even heard of it.
I would like to know if it might be possible to make it more translucent. Any of you know what is the basic usage of this "Balsamo de Peru"? I would highly appreciate for some information.
Thanks,

Dear all,

I´m planning to take some SEM pictures of spider mites and phytoseiids, adults and immatures. Since immatures of phytoseiids and also all the stages of spider mites are quite soft, they might need a treatment with critical point or something like that. The technician at the SEM could not help me
about the substances or the procedure to use so... Can anyone of you give me any help?
If you already have taken some pictures of immature phytoseiid or spider mites (or similar), please, just tell me...
-what did you use to dehydrate specimens?
-which concentration/s did you use?
-Do you have any 'recipe' that can help me?

I would really appreciate any comment about it. Thanks all!

Dear acarologist,

I am at the end of a research concerning the behavior and the chemical communication in Dermatophagoides farinae and D. pteronyssinus. In the general discussion of the corresponding manuscript I try to argue that a social statues in these mites should exist. Could anyone tell me if such a discussion has already been made with another mite species (more specially with astigmatid mites)? Secondly, I have some few informations about a patchy distribution of these mites in the domestic environment. Have someone already observed this kind of phenomenon (for example, by dust sampling) or could you give me references which suggest this?

Thanks a lot,

Dear Liliana,
 
     I am currently preparing some Phytoseiids for SEM.  I am fixing them in 3% gluteraldehyde and      taking them through a series of  ethanol and acetone to dehydrate them.  I then plan to critical point dry and sputter coat.  I have been advised that this should work and am also following the techniques carried out by Flechtmann & McMurtry (1992) - see below.  If you would like any more information about what I am doing let me know.  Our critical point dryer is out of operation at the moment but when it is up and running again, I'll let you know if this method works!
 
     Regards

In collaboration with colleagues of mine I tried various techniques of soft tiny specimens (mites, Trichogramma sp.) preparation for SEM several years ago. Critical-point drying usually resulted in collapse of the body. Good results were sometimes obtained by slow freeze-drying technique but it takes long time.

I finaly used diethyl-ether to dry the material. It was originally described as a method for preparation of insect larvae (see references below) but can be applied to mites as well. The method is based on
fixation of specimen in alcohol after which it is transfered to ether. After having been thoroughly soaked in ether, the specimen is warmed (we used temperature about 60 degress C) to cause expansion of the gas within its body and consequent distention. The heat must be carefully applied and maintained for a few minutes until the specimen has dried in an inflated condition (the alternative is to apply heat of a lamp while observing the process under dissection microscope). I obtained good results with application of this method to phytoseiid mites as well as tiny eriophyid
mites.

I have an old Cambridge S100 that has been giving me a lot of troubles (it is ancient age - it was bought in 1984) and I can get good pictures (see attachments) with a very simple technique in which no critical point has been utilized as rule (because I don't have the tools). To take those pictures I need two things: 1) a SEM provided with a turbomolecular pump, 2) a low accelerating voltage (maximum 5 kV).

The protocol is very simple and fast:

1) take a stub and put on it a drop of bistilled water;

2) transfer the mite/s on the drop of water;

3) kill the mites with a gas (chlorophorm, ethyl acetate, or others);

4) take off the water by means of a piece of clinex or similar, taking care that the mites will not be removed; you can take off not all water at the beginning, then you can place the mites in good position and then you can take off the water completely;

5) put in the SEM chamber, observe and take pictures.

Pay attention that you can work with those specimens not for a long time (max 10 minutes) because the mites can be disidrated and can be magnetized. But I can ensure you about the results after a brief period of experience.

The protocol needs about 10 minutes insetad of a day or more using critical point; the results are more or less the same. This technique was arranged by Nuzzaci and Vovlas in 1976.

I have got very good results on Eriophyoids (I've been working on them since 1986, Phytoseiids, spider mites, larvae, eggs, insects, nematods, and so on).

Sincerely yours,

Enrico

4th International Symposium on Population Dynamics of Plant-Inhabiting Mites

(Second Announcement, 22 May, 1998)

Kyoto, Japan, May 10- 14, 1999

-----------------------------------------------------------------------------------------------------------------------

We are very pleased to announce that the 4th International Symposium on Population Dynamics of Plant-Inhabiting Mites will be held in Kyoto, Japan, on May 10-14, 1999, in a small conference hall (Shiran Kaikan), close toKyoto University.

-----------------------------------------------------------------------------------------------------------------------

The Symposium

This Symposium is a follow-up of the three previous symposia. The first (1987) and second (1991) ones were convened by Prof. M. W. Sabelis in Amsterdam, the Netherlands, and the third (1995) one by Prof. G. Nachman in Gilleleje, Denmark. The three previous symposia consisted of a small number of participants, less than 100 people, and all were very successful and stimulating meetings, with intensive discussions on selected topics.

This Symposium has been traditionally named "Population Dynamics of Mites". However, it has covered almost all areas of acarology: ecology, evolutionary biology, molecular biology, pest management, chemical ecology, behavior, and so on. Thus, the Symposium aims to bring together scientists in various research fields, to exchange ideas and to stimulate future research. We look forward to seeing you in Kyoto in 1999.

-----------------------------------------------------------------------------------------------------------------------
 Structure of the Symposium

Example:

Electorophoretic detection of enzyme variations among Japanese red-colored spider mites of the genus Tetranychus (Acari: Tetranychidae)

Kouichi Goka (a) and Akio Takafuji (b) a National Institute for Environmental Studies, Tsukuba, Japan b Graduate School of Agriculture, Kyoto University, Japan

The genetic variation in PGI and MDH was studied in red-pigmented spider mites of the genus Tetranychus by means of poly-acrylamide gel electrophoresis. The analysis revealed that Tetranychus kanzawai possesses five and three alleles for PGI and MDH,
respectively and that PGI allele frequencies clearly differ between Hokkaido and Honshu populations. ....

Dear all,
THANKS A LOT to all the mite people that helped me with critical point, give me advice and tell me the 'secret tricks' to take good pictures. I´ll let you know about my results as soon as I have them! (we have to travel 400km to the nearest SEM so we don´t have an appointment ´til july).

Good luck!

Subject:  Proctophyllodes - help!

Sorry to be a nuisance.

I am a birdwatcher dabbling in bird parasites.  I have been trying to identify Proctophyllodid mites using Atyeo & Braasch 1966.  Many specimens - from S. England - just don't look right even though I am 99% sure that they are Proctophyllodes and have done some scanning electron microscopy.

Are there more recent references?  I've tried BIDS with little joy.

Are there any people out there interested in this genus?

Problem species are on bird hosts such as house sparrow, tree sparrow, blue tit, chaffinch.

Dear Dr. Harper - The monograph by Atyeo & Braasch is the most recent compilation, although there have been a number of new species described since that work.  You should contact Dr. Sergei Mironov, Zoological Institute, Russian Academy of Sciences, St. Petersburg, Russia, who has been the most active worker with these mites in recent years.  He should be most familiar with the European fauna.
