Insect Pests and Arthropods in Heritage Interiors

Area of Science:

• Entomology
• Heritage Science
• Conservation Biology

Background:

• Insect pests pose a significant threat to cultural heritage objects.
• Factors like climate change, travel, and trade can exacerbate insect infestations in heritage sites.
• Understanding pest distribution is crucial for effective heritage conservation strategies.

Purpose of the Study:

• To investigate the arthropod fauna in Austrian heritage environments.
• To analyze the distribution patterns of common heritage pests.
• To relate pest distribution to building characteristics and ecological theories.

Main Methods:

• Conducted arthropod sampling across 30 diverse heritage environments in Austria.
• Compared catch rates and taxonomic richness between different building types (museums, libraries, storerooms).
• Analyzed pest distribution patterns in relation to building size and environmental gradients.

Main Results:

• Overall arthropod catch rates were lower in storerooms compared to museums and libraries.
• Building size correlated with taxonomic richness, suggesting an island biogeography effect.
• Common pests like booklice (Psocoptera) and common silverfish (Lepisma saccharinum) showed even distribution, while webbing clothes moths (Tineola bisselliella) and rare species exhibited uneven distribution.

Conclusions:

• A core group of pests, including Psocoptera, Lepismatidae, Tineola bisselliella, and carpet beetles (Anthrenus spp., Attagenus spp.), dominate Austrian heritage environments.
• Pest distribution appears to follow ecological principles, aligning with continuum theory.
• Findings provide valuable insights for targeted pest management in cultural heritage preservation.
