I'm an immunologist interested in house dust mites/storage mites, and *why* they are allergenic. As part of this work I've been looking at microfauna/flora co-factors that may affect how an immune response to mites may be skewed towards allergic responses. One of the most obvious co-factors is of course fungi. I am however finding it very difficult to find any written work that describes which species fungi are most important for the mites I am interested in. As far as I can see there may be two factors important in allergic sensitisation to mites that may concern fungi. The first is fungal metabolites passed out in the faeces and the second is the new growth of fungus on the faeces once deposited. Whether these hypotheses are viable or not depends in large part on the species of fungus eaten by these mites, or the species that inhabit the same habitat as the mites.
I wonder if you could help me by pointing me in the direction of some written work on this subject, or suggesting one of your colleagues who may be able to help.

Dear Dr. Hewitt et al.
I reviewed mite-fungal associations in the following paper:
OConnor, B.M. 1984. Acarine-fungal relationships: the evolution of symbiotic associations. in Wheeler, Q. and M. Blackwell (eds.), Fungus-Insect Relationships: Perspectives in Ecology and Evolution. Columbia University Press, New York. pp. 354-81.
This paper concentrates on the use of macroscopic fungi by mites. A better reference on the association between fungi and stored product/house dust mites is the following:
Sinha, R. 1964. Ecological relationships of stored-product mites and seed-borne fungi. Acarologia 6 (Suppl.): 372-389.
Hope these references are useful.

In a field study of colonization of crops by phytoseiid mites, I have
trapped in many locations in France, several species of mesostigmatic mites,
most of them belonging to Ascidae.
Is anybody interested by helping me in identification of these mites or by providing me with the name of a specialist ?
Thanking you in advance,
Dr Serge KREITER.

Subject: Antarctic oribatid
I am interested in the genus Antarcticola Wallwork, 1967. I have the original description of the genus and the type species, A. meyeri. But in the catalog of Balogh and Balogh (Oribatid mites genera of the world, 1992) them write that exists three species of this genus.
Anybody know the other two species, were are published, etc.?
Thanks for all

we are looking for samples of living ticks from some pathogen free laboratory colonies, we need for our comparative biochemical studies:
Amblyomma hebraeum, A. americanum, A. variegatum
Ornithodoros porcinus, O. parkeri
We are able to offer in exchange the following tick species from our laboratory breeds:
Argas persicus, A.reflexus, A.polonicus, A.vulgaris
Ornithodoros moubata, O.tartakovskyi, O.papillipes, O.erraticus
Thanks in anticipation.

Subject: Grad Opportunity in Arachnology
GRADUATE RESEARCH OPPORTUNITY IN
I currently have space and funding available for M.S. and Ph.D. students who are interested in pursuing work in the comparative biology of arthropods, especially arachnids. Current work focuses on the functional morphology and phylogeny of arachnids, but students with related interests are welcome.
I am located in the Department of Entomology at the University of Maryland at College Park near Washington, DC. The Department will soon relocate to a new building with state-of-the-art facilities. The Department has a strong program in systematic biology and is a member of a consortium, the Maryland Center for Systematic Entomology (MCSE), that also includes the Department of Entomology at USNM and the USDA Systematics Lab.
Please address inquiries to:
Deparment of Entomology
University of Maryland
College Park, MD 20742-5575
Current projects in my laboratory include
1) Functional morphology of morphology of locomotion in arthropods
Relevant equipment includes:
enclosed miniature treadmill
2) Two high-speed (60 or 200 Hz) video cameras
3) Electromyography apparatus including 12 Grass AC preamps, 14-channel TEAC data recorder, 16-channel thermal array chart recorder, 4-channel digital storage oscilloscope
2) Comparative morphology and systematics of arachnids
Relevant equipment includes
1) Two Wild microscopes with
2) Microtome, etc.
3) Molecular systematics of the major arthropod lineages (w/ J.C. Regier)
Newly developed nuclear,
protein-coding genes are being used to resolve relationships among arthropods
at the ordinal level, with special emphasis on Chelicerata and Myriapoda.
This is being conducted in a state-of-the-art facility using RT-PCR and
I am an ecologist with a new interest in mites - ie lots of enthusiasm but little experience.
To the west of Stirling is a village which is plagued by a species of mesostigmatid mite. This mite, found in gardens, fields and the park, is pale yellow and bites readily, leaving a very itchy weal, like a mosquito. It is very possible, I am told, to get bitten 30-50 times after a period working outside.
Can anyone suggest either what this is, or, sources of information on biting mites? The library's only reference on mites and ticks is Evans, Sheals & Macfarlane 1961!

Dr. Russell W. Strandtmann, pioneer Acarologist, died August 7, 1996 at his home in Maxwell, Texas. He was 86 years old. He was a grand old man, full of warmth and great humor. He was survived by his wife, Mary Ruth Chance Strandtmann and two sons, Lamar and Sturgeon.
He was at the last IX Acarology Congress in Columbus, Ohio, July 1994.
In 1989, when he retired from Texas Tech, he was quoted in a news article (B. Porterfield, Austin American, 21 April 1989) on his concern about the environment. He said, "I've a great concern about what we're doing to the ecology. People think of the planet Earth as almost indestructible, and it is. But when you consider that life forms such a thin film on this crust of this big bowling ball, then you understand the fragility of life and the organic environment. We must have birth control among humans, and we have to control plants and insects biologically, like nature does, no chemically."
