Subject:  Proceedings Acarology IX

After many delays, the Proceedings of Acarology IX (contributed papers) are published and in the mail.  In order to keep costs down, mailings are by surface mail.  For those who were first author on any of the papers included in this volume, the package also contains 25 reprints of your paper.  In the few cases of authors with either long papers, or several papers, reprints are send by separate mail.

The volume for the symposia is not yet done and will be mailed seperately.

Due to the numerous delays in publication of these volumes, keeping up with all address changes has been a problem.  If you have changed address recently, we would appreciate an update to speed further processing of your volumes.

On behalf of the editors, we apologize for the numerous delays, and hope you will enjoy the final product.

Dear acarology people out there:

Hi.  I'm interested in finding out the mode of action of benzyl benzoate when it kills the house dust mite, Dermatophagoides pteronyssimus.  If you can give me any information, that would be appreciated.

Dear acarologists,

In order to do my behavioural experiments I need to keep my Ixodes  ricinus ticks in a confined area. I already have tried several methods but not with much success. I have used water, vaseline, oil,
electricity, wet filter paper, teflon and combinations of these.

Electricity was by far the most successful method employed described  by Sonenshine (Sonenshine, Biology of Ticks,1991). Here a table is  constructed on which practical work can be done. An elecric circuit  prevents ticks from escaping.

Could anybody help me find a way to construct in a similar way a small arena (c. 4  x 5 cm). It is important for me to find out the amount of Volts and Amperes which prevent ticks from crossing the wires. Whether or not I need a single loup with an earthed platform or a double circuit with +ve and -ve.

I would be very grateful to receive some advices from people who have experience with these animals,

Edwin,

In our behavioural experiments with Ixodes scapularis we used Silva sticky fly paper to confine our ticks.  They are repelled by the sticky surface but do occasionaly get stuck in it and die.  Our goal was to ensure that potential Lyme Borrelia-carrying ticks did not escape during questing experiments.

Dear Sir,

As all ticks of the genus Ixodes possess the Haller's organ, you can probably make use of it.

The Haller's organ receives external stimuli in terms of TEMPERATURE  (try a cold barrier), humidity, carbon dioxide concentration, AMMONIA  (try eventually a barrier with this product), aromatic chemicals,  pheromones and air-borne vibrations. (Hillyard Paul, Ticks of North-West
Europe). For detailed morphology of Haller's organ I refer to  Estrada-Pena et al. (1986) and Homsher et all. (1988, 1991).   I believe that  natural pheromones or hormones of tick enemies are the best resolution as a repellant, a likewise a natural barrier..

 If you have further questions, I'll always try to answer..

Dear Nils,

"As tick mortality results more from starvation than from direct predation by enemies, following natural ennemies have to be taken in account: Birds, e.g. starlings, crows and chickens that eat many engorged ticks which have dropped  to the ground.

Cattle egrets in particular consume many ticks, often direct from the host; and , when licking and grooming the host themselves become predator of ticks.  Furthermore, certain  arthorpods, nematodes and even plants are known to kill ticks.

Recently engorged ticks are vulnerable to predation especially when seeking moulting or egg-laying sites on the ground.  At such times, rats, mice, shrews, lizards and other animals will eat them.  Predation by arthropods is primarly by ants, ground beetles and spiders (Milne, 1950; Barnett 1961).  Jumping spiders, in particular, are known to prey on argasids (Ault&Elliott, 1979; and wolf spiders on ixodids (Wilkinson 1970).  In Corsica, the web spinning spider Teutana triangulosa is a regular predator of the tick Rhipicephalus sanguineus (Sautet, 1936)  And in the USA, introductions of the fearsome fire ants (Solenopsis) into a locality usually cause the ticks to rapidly disappear (Burns and
 Melancon, 1977)

Parasitic insects: several species of hymenopteran wasps and dipterous flies (e.g. Ixodiphagus hookeri) In northern Germany, Ixodiphagus is a minor parasite of Ixodes ricinus.

Predatory mites (e.g. family Anystidae)

Nematodes and bacteria: endoparasitic nematodes, such as Steinernema carpocapse and Heterorhabditis bacteriophora, have symbiotic relationships with bacteria and are pathogenic for insects and other arthropods...

Anti-tick plants: In warm regions, the legume Stylosanthes and other plants as Melinis and Gynandropsis, because of their sticky hairs or acaricidal effects have the potential to repel, trap or kill large numbers of ticks, particularly in managed cattle pastures (Sutherst et al., 1982; Malonza et al., 1992

Sterile release through irradation or hybridisation; when enough sterile ticks are released into an area, a reduction in wild ticks is theoretically possible (Olkowski et al., 1990; Wilson and Deblinger,
1993) " (end of citate)

The above citate comes out of the tremendous excellent superbe work of dr Paul Hillyard, of the Natural History Museum of London "Ticks of North-West Europe, Published by The Linnean Society of London (haven't yet looked them up on the WWW) and is available by ordering it at E.W.
Classey, a book-shop which advertises on the WWW.

Of course, this is only an excerpt..., the book is invaluable to those who study ticks...

All:

 Is there a simple means to separate dust mite fecal pellets from
bed dust (skin scales), such as vibration/filtration, vortex flow, etc?

Thank you,

I'm a budding acarologist and learning some things the hard way.  I purchased quite a few Illex helleri(small leaf holly) to use in an experiment with Tetranychus urticae.  I tried for a month to infest the holly bushes with no success.  Therefore, if any of you need some holly bushes for use for other experiments on mites that like hollies, I have around 200 that I am trying to get rid of.

The hollies are here at Clemson University in Clemson, SC.  If you want them, come get them.  You can call me at (864) 656-5067 or reach me at my email address dwboyd@clemson.edu which ever is best for you.

I found some miniature roses to take the place of the hollies.

Thanks,

David Boyd

Hi everyone,

I work with solitary bees and wasps here in Minas Gerais state (Brazil). In a work using trap nest I collected many nest parasited to mites of genus Pyemotes.  So I'd like know if someone in the list can send me information (who and address) on identification of species this genus.

Please, excuse my errs.

Hi Everyone -

Does  anyone have any information regarding the above  Raphignathoids  as predators of false spider mites in temperate  climates? Also, if anyone could give me a snail mail or e-mail  address of H.R. Bolland (who has published much of the recent  work on this family), I'd be very thankful. His last location was at the Laboratory of Experimental Entomology, University of  Amsterdam, The Netherlands.

Thanks in advance. Please respond to me directly.

Marta:

I have taken advantage of your holiday message to Moose and the  attached "copies" list to relate some very bad news to those who might have  known Moose Reeves.  Moose died December 12, 1996, following a second bout  with cancer.  He had officially retired on October 1, but remained active  until the last week.  In fact he was in to work on Wednesday, December 4.

As a friend and colleague,  I know that Moose will be missed.

Hello!

I would like to do cytological analysis of early development (1-4hs after oviposition) of two spotted spider mite (T. urticae) eggs. The literature I can find refers to optic microscopy with orcein staining methods. What I've gathered sofar includes all the 'classical' papers by W. Helle & H. Bolland, Pijnacker, Templaar, and Koppen. This literature more or less ends in 1984/85. Is there anything done after that? If you know of anything please reply,
Thanks!
 

Filipa.

Is there any literature on the acarology og the vented dust from broiler chicken houses? Has this dust ever been implicated in allergenic reactions?
Thank you all.

I have recently seen publications in the field of systematic acarology and received manuscripts to review in which the authors have been apparently unaware of regulations in some countries regarding the deposition of  type specimens.  Laws in two countries of which I am aware require that
holotypes of all newly described species collected in those countries be deposited in an institution in that country.  These countries are Australia and Brazil.  Costa Rica also requires that paratype specimens be deposited in a Costa Rican collection.  Although I have not seen the text of the actual legislation in any case, discussion with acarologists in those countries has verified the existence of such regulations.  In the cases of Australia and Brazil, regulations apparently cover specimens collected at any time in the past as well as newly obtained material.  Researchers who obtain proper permits for collecting in those countries should already be aware of the regulations, however, often collections are received for study "second-hand" from other collectors or consist of specimens already in out-of-country museums.  In one case, I had to negotiate with an American curator from whose collection I had obtained a new species of mite from a bee collected in Brazil many years ago for permission to forward the holotype to a Brazilian institution.  In view of the Brazilian law, the
curator did give his permission.
        Of course it is always a matter of courtesy to deposit specimens of new species described from foreign countries in recognized collections in any country which maintains them.  This custom needs to be reinforced among the community of systematic acarologists of the world where it is still unfortunately prevalent for taxonomists to retain all specimens in their own institution regardless of the country of origin.  This is even true when appropriate institutions exist to house acarological collections.  For example, I have seen several recent papers by European acarologists describing new species from North America without depositing any specimens in collections in the United States or Canada.  With the decline in academic and governmental positions for systematics in the developed world, the future of systematic acarology clearly lies in what are often termed "developing countries."  Workers in such countries often have fewer library and museum resources than those in the developed world, so cooperation from foreign collectors working in those countries is essential for the continued development of the science.
        It is true that not all systematists in Australia and Brazil agree with the laws noted above.  However, more and more countries are considering such legislation to "protect" their national heritage from "neo-colonialists" who use their resources but provide nothing in return. I suggest that the best way to avoid the proliferation of such restrictive measures is for full and open cooperation among scientists in all countries, including the return and exchange of specimens and literature.
        I invite discussion by list participants.

Dear colleagues,

I would like to support Barry OConnor's comments about regulations relating to the deposition of specimens in institutions. This discussion is especially timely for acarologists planning to visit Australia for the International Congress next year. Several important points must be made.

First, Australian law requires that any specimen collected in Australia after 1983 which becomes the holotype, lectotype, or neotype of a species, must be deposited in an Australian public collection. This requirement applies whether the specimen was dispatched as a loan, exchange, or donation. In the case of mites the appropriate institutions would normally be the relevant State Museum or the Australian National Insect Collection.

Second, any collecting that is done in an Australian National Park or other protected area must be covered by an appropriate permit, which must be obtained in advance. The conditions of those collecting permits usually stipulate that types must be deposited in the relevant State Museum.

Third, a permit must be obtained for the export of Australian specimens from Australia, wherever they were collected.

Australian nature conservation authorities are usually willing to offer full cooperation to the scientific community, and recognise that research adds to the value of the areas they manage, but they are empowered to impose heavy fines if necessary.

As Barry said, the  interests of our science will served best by a spirit of open cooperation and goodwill, and these are things that easily achieved.
