Re: [pestlist] detecting woodborers








Hi,

We will put a linkto  Dan Cull's research on low
temperature treatment for stretched hides on museumpests.net soon.  

Anne, thanks for pointing it out to the list.

 

In the meantime Ellen Carrlee's article Anne mentions
below is in the  low temperature bibliography in Treatments on
museumpests.net here but we will make sure the link is added.

RE: [pestlist] detecting woodborers

[Jerry Shiner]

the Thermo Lignum method involves raising the interior temperature of
infested objects to around 55 C and holding the temperature at that
level for a short time - long enough to kill the insects.  The relative
humidity is carefully controlled during the process to ensure that
moisture is neither lost nor absorbed by the objects. 
 
I don't believe that anybody in North America is offering the system
commercially. The process involves a serious commitment in machinery,
and therefore would be a challenge to offer if the prospective market is
not large enough. It is very fast and effective, but economics make it
best suited for large collections.

Hello Katie, 
I'm not an expert in the process, but the Thermo lignum method (which
combines controlled heat and humidity) has been used on many composite

I don't know if it is available in Canada though.

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 be at all effective in hearing them?

Cheers,
Katie

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

Katie -


 


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 be at all effective in hearing them?


 


Cheers,


Katie

There are also electronic "ears" used in auto (car) repairs, but, of
course, if the insect isn't crawling and scratching and eating, then you
will not hear much at all as Cathy already pointed out.
Can you tell us which "powderpost" beetle you are dealing with?

Hi Katie
 
I've used it - but don't recommend it because it only works if the larvae  
are actively feeding - otherwise they could be present, but you would hear  
nothing.
