Re: [pestlist] anoxic treatment update and more questions
This is a message from the Museumpests.net List. To post to this list send it as an email to pestlist@museumpests.net To unsubscribe look at the footer of this email. --- Hi Nicole As Pascal mentioned, the temperature is going to be critical in ensuring that you achieve 100% mortality. When testing powderpost beetles Dr Mark Gilberg found that it took up to 12 days to kill all stages at 30C and 70RH. You’re using a lower RH than in that test which should reduce the time, but it takes longer to kill insects at lower temperatures (i.e. up to 6 weeks at 20C). If the temperature where you are treating the objects is low you will need to increase the temp. Oxygen scavengers take a number of days to reduce the oxygen level so you need to allow for this when thinking about treatment time as well. Regarding the Anobium life cycle, the adults emerge in late spring/ early summer. This means that there would be minimal risk of cross-infestation as the borers will be in the larval stage at this time (unless they are from the southern hemisphere, e.g. Australia, where the beetles are emerging now).

To post to this list send it as an email to pestlist@museumpests.net To unsubscribe look at the footer of this email. --- Hi Hazra It's a bit hard to say with mould. Some mould attacks can spread very quickly, but it depends on the conditions (i.e. heat and rh), the material being stored, the mould type and how much mould is present. Given the urgency of your problem freezing is a good way to go, but maybe you could use barrier bags (the ones we use for low oxygen work) instead of PE for freezing? The benefits are the conditions inside the bag won't fluctuate like they can in PE bags and the barrier properties prevent most pests from finding the bagged items (e.g. silverfish). Barrier bags come in a range of pre-fab sizes - check with Jerry Shiner at Keepsafe for sizes, etc. If the storage area is high in humidity then you might want to consider placing a desiccant or buffer in the bags before you seal them?

We have found live Anobium larvae in books in an air conditioned and humidity-controlled archive in Australia. Lower temperatures and/or humidity may eventually eradicate borers in collections, but many insects continue to be active under less than optimum conditions, although their life cycles may be slowed or extended. Eliminating an infestation solely under storage conditions would depend on the temp, RH and the length of time, and a great deal of damage can occur in the meantime. I have some really cool photos of damage caused to some carvings which were wrapped in plastic and left for 6 months. Freezing the books and other suspect material will probably be the best course of action.

We do tend to find large numbers of bugs in and around buildings in the tropics. Most of the bugs (and gheckos) are common, but I don't have the scientific name for them.

We have an historical archive with mostly paper and photographic material. There are also textiles, wood and metal items. An Integrated Pest Management Plan was introduced July 2011 and we have happily caught too many insects to count. Given the tropical climate, a building that is not sealable, the vast array of insects and pests, and the limited resources here, we have been very successful in reducing the number of insects week by week using what is available - a can of Mortein surface spray and black plastic small square cockroach bait holders and squashing/removing them. We have rodent traps, sticky traps, cleaning, waste removal and ongoing inspections and awareness training. Our archive is air conditioned which is the best deterrent for tropical insects and pests, but power outages occur and can go for days or weeks especially in cyclone (hurricane) season. I have been training the staff in IPM, insect capture, ID and which type of insects cause what damage to paper, photos textiles etc. I now I am hoping that some people on Pest list have time/inclination to help us add in more accurate information. I’ll be putting together a powerpoint for ongoing training of staff here and other record keeping/archives/museums in Tonga, so any information given will be shared around. If any one has the time, we’d be most grateful to find out more about our insects/pests and what specific damage they do to collections.

The specimens have been stored in a variety of ways including plastic tubs and cardboard boxes. Neither have proven effective as a barrier to attack, especially to highly attractive families the Asteraceae family. We have been using prefabricated high-barrier bags to encapsulate such specimens in an effort to make them 'invisible' to pests (i.e. no odour to attract the bugs). This has been done in conjunction with a number of other steps such as temperature control, pheromone trapping. In short, if there is an existing pest problem I don't think the tubs will afford any protection.

We allow the 24 hour thaw and have not had any problems with internal condensation. I like using the tubs because they provide rigid support and protection and they make it easier to handle, stack, and transport specimens. Here is the part I am not so sure about.

The tree was hollowed out and had also been stored outdoors for a prolonged period. The tree was about 4 yards long and 2-3 yards in diameter. The tree was sprayed inside and out with a product called Perigen (it contains permethrin - a low-toxic synthetic pyrethroid) using a pressure sprayer. It was allowed to dry for an hour before another application was carried out. We also repeated the process a week later. The treatment revealed that the tree had been home to all manner of bugs, including silverfish, cockroaches and red-back spiders (these are similar to your black widow spiders, if you gave them a gun). The subsequent application didn't reveal any further insect activity. I can send photos of the treatment if you like?

It was exhibited outdoors in the South for some number of years, and then was brought to New York but kept horizontal in a cradle in a space next to an unheated loading dock. Although there was substantial old insect damage at the top and bottom, no active infestation was visible until the piece was taken out of the cradle. I am told that there was recent damage in the areas that rested against the cradle. (I have not seen it yet.) Some samples of frass are being sent to me - I am told there are no dead bug bodies around, but that after a piece of white paper was left on the deck, frass appeared by morning. (I suspect that maintenance staff cleaned up without reporting anything.) The piece is now in a corporate lobby (nowhere near any other works of art). So here are my questions: Assuming that there is an infestation, is there any way to fix this other than fumigation under a tarp? I don't think there is anywhere to put it for long enough to do anoxia. At this point, does identification of the critter matter? Is there someone out there who can take on this job? I would be eternally grateful. UPDATE: I received a baggie of debris in the mail. It looks like crumbs of deteriorated wood to me - can't make out any frass, but I would be happy to send it to anyone willing to check it out. Maybe the reason they couldn't find bugs was that there weren't any. Obviously if there is an infestation, I want to do something about it, but it may be that there was water under the wood on the cradle and that freeze-thaw cycles resulted in rotting and crumbling of the wood, particularly where it wouldn't have an opportunity to dry out.

Re: [pestlist] Powder Post Beetles
Hi Robert A few years ago we were asked to treat a Sydney ferry that was on display in a museum which was infested with powderpost beetles. During the refit for display a lot of Lyctus-susceptible timber was used. There was extensive borer activity throughout the vessel, but especially below decks (oh joy) to deck supports, etc. First we sprayed all the timber lightly with water to assist the uptake of the borate. We then applied Boracol to the timber using garden-type sprayers. We had to re-treat several areas a few months later (as further frass was noted), then one or two spots during the following year, but we eventually erradicated the borers. One quick note: The timber you mentioned is very old, so I'm not sure if it will be the same insect as the one we dealt with here. The powderpost beetle (Lyctus brunneus) only attacks timber in the first 20ish years of service. Then the timber is too dry and can no longer be infested (by this borer, anyway). Even if it is another species, I'm sure the borate treatment would work. Best wishes, Alex Alex Roach Heritage Pest Management On 04/02/2011, at 7:54 AM, Jones, Robert (Ryan) rjo...@cwf.org wrote: One of our two-story historic buildings has recently shown signs of powder post beetle infestation. New flight holes (which were filled with frass and intermingled with old flight holes) were located in the exposed ceiling beams of an unused cellar room. The beams were reportedly installed back in the 1940’s. We have noted approximately 20-30 holes in the immediate vicinity that appear to be fresh. We are now trying to decide what would be the best course of action in getting rid of the problem. Our first thought was to secure 8-10 glue board type traps 2-3 inches under the beams (using tape or tacks) to determine if the holes are definitely active. These glue boards would help us track new sawdust and/or emerging beetles so that we could better understand the extent of the problem. If the holes prove to be active, we will have to take additional steps. We were wondering if there is any value to treating the beams with Bora Care or a similar borate product to kill burrowing larvae and prevent future infestation. Most of what I have read about borate sprays has left me wondering whether the finished product would penetrate the wood deep enough to kill any of the larvae. We would certainly like to avoid tenting the structure for obvious reasons. Any thoughts or experiences on the management of powder post beetles?
