Beetle Infestation Threatens Medieval Texts in Hungary Due to Warming Climate

Beetle Infestation at Pannonhalma Archabbey

• 🎯 A significant beetle infestation has been detected in multiple sections of the library at Pannonhalma Archabbey in Hungary.
• 📚 Approximately 100,000 books are being removed for disinfection due to damage caused by drugstore beetles.
• ⚠️ The entire collection is considered infested and requires simultaneous treatment.

Anoxic Disinfection Process

• 📦 Books are being removed from shelves, packed into crates, and then sealed in airtight tubes.
• 💨 Inside these tubes, an anoxic disinfection process is employed, creating an oxygen-free environment to kill the insects.
• ⚡ This method is effective because insects require oxygen to survive.

Impact on Cultural Heritage

• 😥 Librarians express distress over the damage to these priceless volumes, viewing each damaged book as a loss to culture.
• 🔍 The infestation affects books regardless of their publication quantity or replaceability.

Climate Change as a Catalyst

• 📈 Higher temperatures are favorable for insect reproduction cycles.
• 🌡️ Below 20 degrees Celsius, beetles are relatively inactive, but warmer temperatures increase their activity.
• 🔄 In consistently warmer conditions, beetles can complete multiple reproductive cycles per year, potentially doubling their generations compared to cooler periods.
• 🐛 For instance, the drugstore beetle's life cycle can occur up to four times a year in warmer climates, compared to only twice in cooler conditions.
