You can always (try) to contact Doctor FAIN of "Het Tropisch Instituur van Antwerpen" to get some tips or "Het Koninklijk Belgisch Instituut voor Natuurwetenschappen, Vautierstraat, Brussel"

Subject: Re: dimorphic protonymphs?

I would suggest to read the following paper:
Gaud, J. & Laurence, B. R. (1981). Surprenant polymorphisme des formes immatures chez l'acarien plumicole Kiwialges palametrichus (Astigmata, Analgidae). Acarologia 22:209-215.

I am describing an example of dimorphic tritonymphs in Chiasmalges (Astigmata:Psoroptoididae), but the differences between the sexes are not as spectacular as the Gaud & Laurence example.

 From my experience with quill mites of parrots, it is common to find more than one species of the same genus in an individual quill (i.e., Paralgopsis (Pyroglyphidae), but fortunatelly we often find PHARATE specimens.

At 12:06 PM 29/08/97 +1000, you wrote:
Dear Acarologists:

Has anyone ever seen/read about dimorphic protonymphs in the Astigmata?  I am playing around with quill mites (Ascouracaridae) at the moment, and have collected what are either (a) representatives of two species that have different protonymphs but similar looking adults, or (b) representatives of one species with dimorphic protonymphs.  The two types of protonymphs often co-occur in the same quill.  Is sexual dimorphism ever expressed in the protonymphal stage?  Males and females are mildly sexually dimorphic, but less so than the protonymphs.

Awaiting enlightenment,
Heather

Quantiative methods were examined for spatial aggregation and refugia of mites in a recent article that might be of some help.

Dear all,
recently I have found a note in a botanical guide concerning trees.  Some Tilia spp. have some mite associations underneath the leaves, so called "acarodomatia". I know the term "domatia" from ant associations.  Does anyone have more infomation about it? I would appreciate to hear more about it.
Thanks in advance

Dear Dr. Schatz.

Acarodomatia were reported for a long time. Coffee leaves have conspicuous domatia.
Two excelent papers on leaf/acaro domatia published recently are

Walter, D.E. & D.J. O'Dowd, 1992 - Leaves with domatatia have more mites. Ecology 73(4):1514-1618
Walter, D.E. & D.J. O'Dowd, 1992 - Leaf morphology and predators: effect of leaf domatia on the abundance of predatory mites. (Acari, Phytoseiidae). Environm.Entomol. 21(3):478-484.

'Domatia' are a particular characteristic in leaf morphology of some trees. These leaves have a bunch of hard hairs right in the angle between the central nervation and the surface of the leaf, usually near the petiole. They arise form the nervation forming like a 'little roof' on the leaf surface. Many mites do prefer this sites as a 'refuge'. Phytoseiids, for instance, tend to stay there while they are not searching for preys and also they lay the eggs mainly in these areas. It is an interesting item to pay attention in a study of micro-habitat and host sellection in plant inhabiting mites, since refugia is an important factor to keep relatively high densities of predacious mites that control mite pests.

Since I have e-mail at home and my publications library is at work, I will send you a couple of references on monday for sure, that might be useful for you.

Hasta pronto!

Liliana.

Mite-'acaro'-domatia associations have been known for over a century. Interestingly, the first reports were by a Swedish worker (Lundstroem 1887) on a Tilia sp., the same plants Dr Schatz saw referenced in his botanical guide.  Lundstroem thought that the mites could be protecting the leaves from fungi and other plant parasites, and made an analogy to the ant-domatia associations that had recently been reported.  However, his ideas about a possible mite-plant mutualism were not well received by botanists (who denied both the association and any possibility of a benefit for plants) and his ideas languished until the late 1980's when Dennis O'Dowd and Mary Willson in Australasia and Bob Pemberton and the late Charlie Turner in the US simultaneously began reinvestigating the
association.

Before the advent of widespread use of synthetic insecticides made it clear that mites could severely affect the fitness of plants, perhaps the idea that plants could benefit from an association with beneficial  mites seemed too farfetched. However, the beneficial mite - leaf domatia association is one of the most predictable ecological interactions I've ever had the pleasure of working on.  Phytoseiid mites and other small predators respond very strongly to the presence of leaf domatia, and fungivores are also quite commonly associated with leaf domatia (as Lundstroem first suggested).  What I know about mite-domatia associations through early 1995 is summarized in:

Walter, D.E.  1996.  Living on leaves: Mites, tomenta, and leaf domatia. Annual Review of Entomology 41: 101-114

Additionally, anyone interested should consult:

Karban et al. 1995.  Abundance of phytoseiid mites on Vitis species: effects of leaf hairs, prey abundance and plant phylogeny.  Experimental & Applied Acarology 19: 189-197.

O'Dowd & Willson  1997.  Leaf domatia and the distribution and abundance of foliar mites in broadleaf deciduous forests in Wisconsin.  American Midland Naturalist 137: 337-348.

and the elegant recent note:

Agrawal, A.A. and R. Karban  1997.  Domatia mediate plant-arthropod mutualism.  Nature 387:562-3

The Associate Diagnostic Knowledge Base does not list Saudi Arabia as an endemic area for Tickborne Encephalitis.  The case description given closely fits that of Crimean-Congo Hemorrhagic Fever which has been found in Saudi Arabia.  Of course CCHF virus is not a flavivirus.

This is a very interesting situation.  I hope for further clarification.[So do we all - Mod.JW]

Hi there!
I am going to start a project to work on Neosiulus idaeus and Phytoseiulus macropilis and I would like to know if any of you have worked on these two species. If you have any publications about these phytoseiids, I would really appreciate receiveing them. I have already contact some people that  studied these predators and I have collected some reprints. However, I did not contact some other because I could not get their e-mails... does anyone have the e-mail address of Dra. Nora Mesa (Colombia); Dr. B. Megevand (Benin); and Dr. V.Prasad? Thanks in advance!

Dear acarologists:

I usually work in oribatid mites, but a colleague has brought me some exemplaires of mites from nasal ducts of sea lion (Otaria and Arcthocephalus genera) and sea elephant (Mirounga leonina) from argentinian coast. He is waiting any help from me, but I have just one paper by Newell (1947) about Halarachnidae (Mesostigmata). Could somebody help me?  The questions are: Is there a comprehensive paper (including a key) about Halarachnidae more new than Newell's work?  How can I obtain these information? Thanks in advance

Dear colleagues,

Can the bee mite specialists perhaps tell me if there is new information on Mellitiphis alvearius Berlese available. I identified it for the first time from bees, collected in Kwazulu/Natal, South Africa. I would like to know if  they pose any threat to Apis mellifera? Thanking you in anticipation.

Regards.
Eddie Ueckermann

I am also interested  in a newer key of the family Halarachnidae.  I received nasal mites from Sea Otter from Japan from a veterinarian friend and I find it difficult to identify with few publications to consult.

I'm on a search for info about the common bamboo mite, Schizotetranychus celarius. I need to know some basic biology (overwintering stage, where it OW's, etc.). I've a little info but nothing with much depth. If anyone has found successful control measures, I could use the help.
