Argon is generally considered an inert gas.   Please clarify why you are 
claiming that " 'inert' gases are likely to foster fungal growth."   You 
mentioning your use of argon systems for over 10 years would seem to contradict 
your own claim.   Any inert gas that can be use to displace O2 should actually 
inhibit bacterial and fungal growth.   One need only look to the use of 
nitrogen and carbon dioxide in food packaging used to increase shelf life.

Many thanks for any literature links you could send us to clarify what you 
meant.

Dear Dr. Diego;

 

The most reasonable option is to use anoxic system, specially with argon 
protocol. This is due to the fact other "inert" gases are likely to foster 
fungal growth.

 

Please give me a call when you can, and I'll be pleased to help you as I'm 
using argon's anoxia systems here in Brazil for over ten years.

RE: [pestlist] Treatment for bedbugs found in bound materials

[Pine, Steve]

Hi Holly:

My reading on Bedbugs consistently indicates they are parasitic.  They
feed on the blood of warm blooded animals.  Is there an indication they
will search out books?  I think the books will be safe even if they do
have leather covers.  Maybe someone else has experience to the contrary
but otherwise I think the books have more to worry about contact with
people than with Bedbugs.

 

As an aside, I've had consistently good results eradicating all types of
insects using Nitrogen with anoxic technique without concern for
chemical interaction with collection materials nor for thermal
complications possible with heating or freezing.   Alternatively, good
housekeeping, vacuuming and repeated inspection is safe and effective.

 

Best of luck,

Steve

Subject: [pestlist] Treatment for bedbugs found in bound materials

 

Colleagues,

  I am trying to work on a procedure for treating bound paper materials
that have bedbugs.  We haven't had any confirmed sightings yet in
materials, but considering our State-wide problem I fear it is just a
matter of time.  I've seen plenty of good information related to
facilities, but not a lot related to caring for books that have been
affected.  The most common quick quip is that they should be "cooked" at
temperatures around 140 degrees Fahrenheit for 2 hours.  I've not seen
any indication what they are being cooked in.  There is a device called
Packtite that gets some mention on blogs, but not on any
conservation/preservation sites.  NEDCC, LOC, and Lyrasis sites don't
have anything yet either.  From what I've read freezing apparently
doesn't kill the egg stage.  My concern right now is the general
circulating collection, so freezing might be the only option for
rare/unique materials   

 

  Has your institution started tackling this question?  Any help would
be appreciated!

RE: [pestlist] detecting woodborers

[Pine, Steve]

I agree with Tom but want to add to the subject of freezing furniture.  Of the 
dozens of furniture conservators I know I’m unaware of any that recommend 
freezing.  They prefer anoxia.  The complexity of issues of differences in 
thermal expansion and contraction of disparate (and aged) materials that Tom 
refers to are a major concern.  Add to that gilding, painted surfaces, modern 
materials like PU foam and so many other concerns associated with trying to 
control condensation buffering during the cycling below and above freezing and 
it is just too risky to recommend generally.  There will be the odd ladder back 
chair and simple chest that can get through it without noticeable trouble and I 
think that encourages the continued perception in some quarters that furniture 
freezing is safe.

PPB's usually go through a one or two-year life cycle, depending on the 
species.  They leave small, round exit holes.  They are not like some of the 
structural, long-horned beetles, which may take up to 10-13 years to emerge as 
adults.  These beetles leave large, usually oval exit or flight holes. Some 
have used portable x-ray units to find them in furniture.  Injection of the 
exit or flight holes with a pesticide is not a logical approach for the beetles 
have already emerged.  In my career working with museums and conservators, most 
furniture and objects can be successfully frozen without harm to the piece.  
One should not freeze inlaid or parquet pieces, because of the dimensional 
problems previously mentioned.

If you are going to listen for these borers then late spring/early summer may 
be best time. Amplified, digitized, and recorded sound of their activity has 
been described in a recent WAG paper by a French person, and not yet 
online/published. Listening can help monitor, but not solve the problem. Is 
your issue with wood beams (structural) or decorative material?

Freezing and warming cycles are not good for wood Art, specially mixed media. 
Mixed media has different contraction rates, does not respond well to dramatic 
temperature change. Some will say they did it without consequences, may be 
luck. You need to understand the risk and how much you are willing to gamble.

 

CO2 measurements can be obtained down to parts per billion. You can use this 
method to monitor one insect in an object. It does take time and experience. 
With newly developed equipments times have been cut to a few hours. Ten years 
ago almost 8 hours on a FTIR.

With good equipment a CO2 analyzer balanced with a O2 analyzer can offer some 
results without an FTIR.

Hydrogen phosphide is not a good penetrator of wood for control of 
ppbs.  If the items are small a freezing process, followed by a warming, then 
plunging the materials again into freezing will elimiinate active infestations 
in wood.

 

The first time do it at -20 degress F for 72 hours; then warm the 
object up to room temperature, then freeze 'em again for 3 days at -20 degress 
F.  Your problem will be elimanated.

Hi, 

 

My name is Katie Fisher and I’m the new Pest Control Technician at the 
Glenbow Museum. I just wanted to ask a somewhat out-there question regarding 
the detection of wood borers… this museum has been battling Powderpost Beetles 
for quite a while. Every 5 or so years a new wave will appear, a large-scale 
treatment process will happen (phosphene), but it just doesn’t seem to be 
effective in getting rid of the Powderpost population. 

 

Since it takes years for them to exit the wood, I feel like I’m 
somewhat just twiddling my thumbs in the meantime, wondering if the last 
treatment did the trick. A friend suggested that I might be able to use a 
stethoscope to hear the larva inside the wood… does anyone do this, to detect 
woodborers? Does anyone think it would

RE: [pestlist] Sucrose and wood

[Pine, Steve]

Thanks Tom.  I’ve read that and yet find myself wondering if there is a 
limiting factor at work similar to what we find with varied carpet beetles 
preferring wool to silk though both are ready sources of protein.  I found 
myself wondering why otherwise there isn’t a history of wood borers infesting 
refined sugar?  That must be too simplistic but you get what I mean.

Certain wood boring beetles are confined to the sapwood of hardwoods (because 
of the sugar content) and others to the sapwood of softwoods.  The real 
powderpost beetles (Lyctidae) prefer woods high in sugar content; hence they 
often infest bamboo and of course hardwoods.  The Old and New House Borers 
prefer the sapwood of softwoods.  The nutrient value for the beetles is highest 
in the sapwood.

 

I am not certain of the type of sugar found in these materials naturally.  
Someone else will have to answer that question.  Does a sugar maple have 
sucrose or some other form of sugar?  What's the sugar in bamboo?

I attended a presentation recently that brought up a question that I couldn’t 
answer so I’m bringing it to the group.  In a conservation treatment of 
waterlogged wood a process of consolidation was utilized where a thinned 
concentration of sucrose in water would be added to the wood structure as a 
bulking agent that would also impart more strength to support the weakened wood 
structure and retain the object’s shape.  It has been in use since the mid 80’s 
when Jim Parrent developed the process.   At that time it was his opinion that 
the added sucrose would not increase the likelihood of infestation.  I can 
visualize the connection between the starches wood borers digest and the 
chemical relationship to simple sugars but wasn’t clear on how to justify that 
the borers wouldn’t be attracted to the sucrose.  My guess is that there are 
enzymes and nutritional regulators that preclude the borers from processing 
sucrose.  Can someone explain why or that my assumption is wrong?

Thanks for the help.
