I'm not a professional acarologist, just an entomologist with an interest and my question is horticulturally biased. The mite
Brevipalpus oncidii is becoming an increasing problem on orchid collections in the U.K., particularly affecting species of the genus
Pleione. It results in poor growth, a lack of vigour and over time the pseudobulbs become smaller and smaller, ceasing to flower.
I should be most grateful if anyone could provide me with any information on this pest. Particularly I would like to know :

1) What is its life cycle and how long do each of the stages last ?

2) What is the life span of an adult mite ?

3) Are there any pesticides availble to amateurs which may kill it and would these affect the eggs as well as the adults ? ( I am
aware that the pesticide Childion which contains dicofol and tetradifon is used by commercial growers, but is unavailable to
amateurs). Would Bifenthrin (eg Polysect) or Imadoproclid (eg Provado) be likely to have any affect ?

Thanks in anticipation,

Paul Cumbleton

Is anyone in the histology end of things familiar with alternative names
for Stevenel's Blue as a stain?

many thanks,

Mites of the genus Brevipalpus are suceptible to "Sulfur based pesticides".

I do not know any specific product used against  B. oncidii  but if you use
these sulfur products remember that it can be phytotoxic to the  plant,
specially under high temperatures.

The life cycle of  B. oncidii Baker 1949 is unknown but I am sure is very
similar to B. obovatus, B. californicus and B. phoenicis, please check:

Does anybody know where I can get hold of black filter paper,
preferably in the UK?
Thanks,

Does anyone know the geographic distribution of Petrobia latens (Brown
Wheat Mite) in North America?  In particular, has it been reported from
Alaska or other high-latitude regions?  Thanks.

Dear List Member,

Since the Entomology Events Calendar was first posted three weeks ago
(at http://www.sciref.org/links/EntEvent/index.htm), it has roughly
doubled in size -- from a total of about 350 events to over 700!  We
are grateful to the members of this list who have either submitted
announcements for their events to us directly, or who have posted
them to the list.

In light of this growth (and the expectation that it will continue) we
have constructed several indexes to help users find events of interest
among the lengthy chronological lists.  Indexes based on the following
criteria have been created thus far:

 - an alphabetical index by the name of the society or association lists
all events which are sponsored by such organizations;

 - an index by event type (such as commercial meetings, courses, etc.)
lists all non-society events;

 - an index by taxonomic group provides separate lists of all events
(in some cases only a few) which are dedicated to Arachnids (incl. Acari),
Ephemeroptera, Odonata, Plecoptera, Neuroptera, Coleoptera, Diptera,
Lepidoptera, Trichoptera and Hymenoptera.

 - separate indexes have been created which list all of the:

       (i) apicultural events,
       (ii) mosquito and vector control events;
       (iii) pest control, IPM, crop protection, and plant protection events
 

These indexes should make the Entomology Events Calendar much easier
to use, and easier for event organizers to determine if their event is
already listed.  The Calendar will certainly continue to evolve as it
grows over the next several weeks.  We look forward to receiving more
information about future events and suggestions on how to improve it.
 

Sincerely,

Subject: Serious mite infestation, possibly "STRAW ITCH" or "BIRD" mites.
To: acarology@nhm.ac.uk
 

For the past several years I have dealt with reoccurring infestations of
BITING MITES that appear around November and after many
extermination attempts lasted several months...this last time they NEVER
left.  There is a huge POD producing tree next door which directly hangs
over my apartment entrance and now I have read that these pods, when
they land and break open, may be delivering these biting mites to me.
They are nocturnal, burrow into the skin, and are now in the rugs,
bedding, furniture and clothes in every room ... but for the first time the
people upstairs have noticed them too.

PLEASE HELP.  Hardly anyone knows anything around here about mites.
I am tortured - and they hurt!!  My friends get bitten when they visit and I
need an EXPERT who really knows these monsters.  I live in Los
Angeles.

Most sincerely,

Paulette Brandt
