IPM Working Group Meeting 2016 PROGRAM ANNOUNCEMENT

MPBugTarget

Sponsored by the Yale Peabody Museum of Natural History
March 16 – 18, 2016

The Integrated Pest Management Working Group (IPMWG) is grateful to long-time supporter Yale Peabody Museum of Natural History for hosting the 2016 meeting. These proceedings will build on the success of 2014’s Williamsburg conference MuseumPests 2014: Integrated Pest Management for museums, libraries, archives and historic sites and the expanded working group program hosted by the Smithsonian Institution’s Museum Conservation Institute in Suitland, MD in 2015.

As always, the IPM Working Group meetings are designed to help institutions with active IPM programs by bringing individuals together to tackle projects related to particular pest related challenges.  All information resulting from these collaborations are placed on the museumpests.net website for the benefit of the cultural heritage community.  The IPMWG meetings do not teach IPM and are not appropriate for individuals not working with an active IPM program.  For more information on establishing a program please consult the museumpests.net website.

The 2.5-day program for 2016 will begin in the afternoon of Wednesday, March 16 with a series of optional tours and talks held at Yale University’s West Campus facility.  Tours will highlight collections in the Peabody Museum and Yale Art Gallery as well as the new Institute for the Preservation of Cultural Heritage, including their research, conservation, and digitization labs. A presentation by staff of the European company Thermo Lignum is also planned.

The subsequent two days (March 17-18) will return to the traditional IPMWG schedule focusing on further development of the online content for the museumpests.net website.  Short 5-10 minute presentations by participants on IPM related at their home institution are interspersed with the work sessions.  If you would like to present to the group please indicate your interest when you RSVP for the meeting.

There is no fee for attending the program but participants are responsible for their own travel, room and board.  Additionally participants are expected to take on an assignment that will result in content for the MuseumPests.net website.  The two and one-half day program is by invitation only as space is limited.  To request a spot please RSVP by emailing thechair@museumpests.net, and please include IPM-WG 2016 meeting in the subject line. Your request must include name, address (company/institution), phone # & email address.  RSVP’s will be accepted through March 1.  Priority will be given to returning participants on a first come, first serve basis and to new participants who are actively involved in an IPM program in their institution.

Confirmation of a spot for the meeting will be made via email and participants will receive a welcome packet via email with additional information on schedules, accommodations and other relevant information.

2015 IPM-Working Group Meeting Day 2 & 3 Summary

IPM-WG Meeting Day 2 & 3 Summary

The second and third days of the 2015 IPM Working Group meeting hosted by the Smithsonian Institution’s Museum Conservation Institute continued with return to the standard meeting format of discussing the usage and needs of the museumpests.net website and the goals established by the subgroups and participants volunteering for assignments to develop new resources and update portions of the site.  In addition, participants gave updates on some of their IPM related projects for the education and benefit of the members.  These included short presentations by:

Cigarette Beetles – Tom Parker

Cigarette beetles (book worms) are cinnamon colored beetles that fly and characteristically roll over on their backs. The larva eats books creating tunnels. The eggs are often found in imported dried red spices and paper mache doll puppets. They are usually found in areas that do not screen their windows. They are found in Malaysia and natural food store spices in bulk. You might notice a cigarette beetle egg pop when you smoke cigarettes since they are also found on tobacco leaves. Tom described a project that included flying a 747 of art work for the new wing of the Dallas Art Museum. Wood boring beetles were suspected when holes were found in the back of black lacquered chairs with inlaid mother of pearl. The cigarette beetles were eating the bed of paper mache that the mother of pearl was laid in.  Damage was also found in an antique dry sink where glue was used for its joins. Piles of powder on the top edge of books is an indication of infestation. When the books are removed the frass is obvious.  The book worm larva can do severe damage to old books where the paper is made up of ground up wood. Lowering temperature is a successful technique removing infestation from collection items. Putting in a freezer for a week will work although about three days should be enough. Minus 20F at 72 hours is recommended. Ice crystals must form within 4 hours or the beetle may build up “antifreeze”. Parasitoid wasps of cigarette beetles 2 or 3 mm long may show up in traps along with the beetles.

Does the Use of Pheromone Monitoring Traps Make my Collection More Attractive to Insect Pests? – Patrick Kelley

Grain moths were used as part of a pheromone study including  different types of fabric and sticky traps. The fabrics used include Antique wool carpet, modern synthetic carpet, modern synthetic flat weave (black) antique wool flat weave (ivory) and antique wool flannel (red). The fabrics were exposed to the pheromone using black four inch drainage tubing in two foot long sections. A wire hanger was placed inside to hang a bullet lure of a 4.5 milligram dose of pheromone blend. Screening on end prevented accidental contact with the lure. A constant air flow was blown past the pheromone onto the fabric swatches for two weeks. The measured wind current target was 130 and 160 per minute allowing a constant light breeze for two weeks.

Traps were placed against a wall with the exposed fabric inside as well as traps with no pheromone or no fabric and also one with an entire bullet pheromone lure. Over 100 moths were let out into the room.  The pheromone lure attracted the most moths, the exposed fabric next and then the control fabric.  The modern synthetic carpet with pheromone attracted more than the control fabric.  The plastic base of the carpet does not absorb the pheromone very well and may have also been more exposed to the pheromone.

Lunches

Our networking lunches included appetizers of edible bugs from Mexico.  We also looked at Louis Sorkin’s specimen collection including live caterpillars!
