Dear acarologists,
We have some problems with O. bacoti in our animal
house where mainly
laboratory mice are kept. We tried several weekly treatments with permethrin
but to no availe. Can anyone advise on what acaricide to use and how
to
apply it?
Thanks

Question:
Does anyone have any information
on the modes of dispersal of the
fowl mite Dermanyssus hirundinis? I am currently trying to assess
how they
are transmitted from one house wren (Troglodytes aedon) nest to the
next.
Although I believe that the adult birds are the primary mode of dispersal,
we have yet to detect these mites on adults(even after the young have
left
the nest). Rather, they're seen predominantly in the nesting
material and
on the nestlings.
Thanks,
Andy Pacejka

Colleagues:
I am presently involved in a study of the genus Sphaeroseius,
a rarely
collected group of large, long-legged dermanyssoid associates of army
ants.
Specimens have been collected both from ant nests and from active swarms
and
columns. If your holdings include any Neotropical material that
more or
less fits the above description and modus operandi, please contact
me.
With thanks,

It is not enough that you apply the right acaricide/insecticide.
You did not
mention
where you apply the Permethrin, if you change the substrate in each
cage,
clean the entire rearing area, if you check the animals which may harbor
the
mite (possible source of new infestation). I suggest remove all
the
animals from the rearing room into a clean, non-infested area; spray
thoroughly the cages, crack, crevices, plug holes of the old rearing
room
(prevent other animals with mites from coming in), put new beddings
in
cages after treatment, etc. Move the animals back. This
should
help. If it does not, you might start thinking of another rearing
room, free of mites.
Aloha. Sabina

Dear fellow acarologgists:
Many people kindly responded to my request regarding Hoyer's medium.
They
are very infromative and some of the responses are of general interest.
Since the responses were sent to me instead of the net, I forward here
a
digest for your information.
(1) The student would do well to read the following paper before embarking
on
the use of Hoyer's medium: Upton, M.S. 1993. Aqueous gum-chloral slide
mounting media: an historical review. Bull. Ent. Res., 83: 267-274.
He
goes into considerable detail about the serious problems that have
been
encountered with Hoyers - its longevity and safety are dubious - and
recommends that it not be used for permanent mounts. He states "those
workers still contemplating the use of these media should seriously
consider
the likely consequenses should their collections become lost to science
[through deterioration of the medium] in years to come. I was an avid
user
of Hoyers until I read this paper, and saw some important material
that has
been completely ruined after only 15 years in Hoyers. I no longer use
it at
all, favouring Euparal for permanent mounts.
Sent by: Matthew Colloff (matthewc@ento.csiro.au)
(2) At OSU we ended up making our own Hoyer's due to the poor quality
of
the purchased material. The only trouble was getting high quality
Gum
Arabic. For Hoyer's, it's best to use the large crystals but most suppliers
now only sell the powdered kind (and this leads to lots of small bubbles
in
the media, _very_ hard to get rid of!).
Sent by: macraei@bugs.AgSci.ColoState.EDU (Ian MacRae)
(3) Hoyer's medium has not been commerically available in the USA for
some
years because chloral hydrate, a main ingredient, is a controlled
substance under US law. Individuals should check whether their
institutions have the required permits to store and transfer this
material. If so, the other ingredients are readily available,
and the
medium is not that difficult to prepare although it is time consuming.
I have also found that it is very difficult to obtain acacia gum (gum
arabic) in its raw form through "normal" chemical supply houses in
the
USA. They typically sell the purified, powdered form which is
quite
difficult to dissolve completely. I have solved the problem by
obtaining acacia gum in lump form through a local Indian grocery [sold
as "eatable gum"].
Sent by: Barry M. OConnor (bomc@umich.edu)
(4) We've always made our own. I don't know of a commercial source in
the US or
anywhere else. If one exists, I'd like to know as well! If you decide
to
make your own, one problem may be purchasing the chloral hydrate as
I
believe it is now considered a controlled substance, at least here
in the
US. Try to obtain the crystalline form of gum arabic as it will prove
easier to work with. Also, "aged" Hoyer's seems to handle better than
newly
prepared material. I have some prepared in 1975 that's just right!
There's
instructions for making Hoyer's in Krantz's Manual.

remember there was a survey about media for insects and mites on that
network last year (Dr. Bruce Halliday, leading the discussion). The
resaon
against Hoyer's is obvious, but do we have a better alternative.
I rarely
use Hoyer's anymore and do most identifications using temporal mount.
I do
want to have permanent mounts, but I have no solution at the moment.
Upton's paper suggests euparal and other perminent media. I have
seen
shrunk specimens in this medium (perhaps improrperly prepared?) and
we have
specimens in gum choral in the British Museum that were prepared by
S.
Hirst in early 1900s that still look amazingly clear. I am sorry
that I
have to raise this question again for discussion, but it is an unsolved
problem for many of us. Sharing experience is likely beneficial
to all of
us.

else really. Hoyer's is not a permanent media. I have been associated
with
several collections in my career and _all_ of them have had to deal
with
the problem of deteriorating slide collections in Hoyer's. Remounting
such
material is tedious and expensive. If you value your specimens and
feel
they have something to contribute to the future of science, be aware
that
Hoyer's slides will barely outlive you. I have not seen any ringing
material that works 100% of the time. If you wish to use the slides
only
for the duration of a research project, then Hoyer's is fine, but be
sure
at least to mount up a set of vouchers in balsam.
