A1 - Plarre, Rüdiger T1 - LLIN (Long-lasting Insecticidal Netting) as a barrier protection against museum pests of major importance N2 - In IPM, setting physical and chemical barriers is a cornerstone for pest prevention designed to protect cultural heritage objects in museum settings. Combining a physical barrier with a chemical barrier in the form of Long-Lasting-Insecticidal Netting (LLIN) has proved to be effective against mosquitos in many parts of the world, while in museums there have been promising studies of LLIN for monitoring and controlling Tineola bisselliella and dermestids. This research explores the efficacy of LLIN as an IPM tool in three unique settings to help inform how they work against other major pests of museums. In the first study, we tested the suitability and efficacy of LLIN under controlled laboratory conditions to prevent hatching of Anobium punctatum from infested material. Artificial breeding material containing multiple A. punctatum full-grown larvae and pupae inside and with expected hatch of adult beetles shortly was enclosed with LLIN. Number of emerging beetles and their longevity was compared to an equal setup with an untreated variety of the netting. While emerging beetles with contact to untreated nettings showed a normal lifespan of up to one month, those with contact to LLIN died immediately or within one day after, thus preventing their potential spread completely. In the second study, the efficacy of LLIN as a barrier protection against grey silverfish, Ctenolepisma longicaudatum was tested by quantifying C. longicaudatum mortality rates after different exposures times to LLIN. The third study takes the LLIN into the field to determine efficacy and practical implementation as a containment barrier for cyclical A. punctatum populations in historic house structures. Infestation by A. punctatum has been a recurring and widespread issue at Gedney House (c. 1665), a non-climate controlled, wood frame building in coastal Massachusetts USA. Over the years, Historic New England, as stewards of the property have implemented many historic preservation and conservation IPM practices, including landscaping measures, water mediation, and regular inspections as part of a holistic IPM program. Many pest species thrive in damp and warm conditions, making Gedney House a prime infestation risk. LLIN was hung in various areas of the basement of the Gedney House with a construction-grade vapor barrier, Tyvek, as a secondary layer for collecting dead A. punctatum after emergence from the rafters and other architectural fragments and subsequent contact with the netting. After 18 months, a large volume of dead A. punctatum caught in the LLIN and vapor barrier encapsulation was observed. This study illustrates how LLIN can be a useful tool for a non-destructive, minimally invasive IPM program implemented by museum staff to monitor and understand A. punctatum activity. The combined results of these studies will inform museum professionals and pest management specialists how to best utilize LLINs in museum settings when trying to prevent damage from these majorly important pests of museums.

Vergleicht man historische Schauvitrinen, die zumeist aus einfachen Glasscheiben in Holzrahmungen bestehen, mit heutigen Konstruktionen, lässt sich eine Entwicklung zu hochtechnisierten Gebilden ablesen, die deutlich mehr Ansprüchen genügen müssen als in der Vergangenheit. Zahlreiche Beispiele verdeutlichen, dass Kunstwerke nicht nur außerhalb, sondern auch innerhalb von Museen oder Archiven ungünstigen Umwelteinflüssen ausgesetzt sind. So können Einbauten bzw. Dekorationen in Ausstellungsräumen, Aufbewahrungsbehältnisse in Depoträumen oder Ausstellungsvitrinen flüchtige Substanzen, sogenannte VOCs (Volatile Organic Compounds) freisetzen, die zu irreversiblen Veränderungen an den Objekten führen und diese schädigen. Hierzu zählen organische Säuren, wie Ameisen- oder Essigsäure, aber auch Verbindungen, die Sulfide enthalten. Hier wird die an der BAM entwickelte BEMMA-Bewertungsmethode vorgestellt, die von Museen verwendet werden kann Materialien mit einem geringeren Emissionspotential auszusuchen.

N2 - Museums worldwide are equipped with different display cases. Exhibit display cases should protect cultural objects from dust as well as from mechanical and physical damage. To ensure a stable climate inside the display cases, a low air exchange rate is maintained. Typically, air exchange rates are often smaller than 0.1 d-1, which can result in rising concentrations of potential harmful VOC inside of the display cases due to emissions from materials. Especially organic acids, e. g. formic or acetic acid which can emit from e.g. sealing materials or wood-based materials, can produce damage of cultural objects. In 2012 BAM introduced a procedure which is called: BEMMA-Scheme (Bewertung von Emissionen aus Materialien für Museums¬ausstattungen) which stands for: “Assessment of Emissions from Materials for Museum Equipment”. Regarding the testing procedure only construction materials were evaluated, not the display cases their self. Micro chambers are used for VOC emission tests of display case construction materials, e.g. plastics, sealing materials, coatings, textiles and others. Each sampling procedure is carried out in duplicate. Emissions like formic acid, acetic acid, formaldehyde, piperidine-derivates and oximes are excluded and the sum of emissions of VVOCs, VOCs and SVOCs is limited. For a positive assessment all listed criteria must be fulfilled; otherwise the display construction material fails the BEMMA scheme.
