[Nhcoll-l] Pest treatment and VOC management in natural and plastic vegetated dioramas

[Marion BILLOT]

Dear all,

I am reaching out to the list to gather feedback and experience regarding heritage dioramas that include natural vegetated elements (reeds, dried foliage, etc.) as well as plastic vegetation. These materials are known to present both a higher risk of pest infestation and potential issues related to VOC emissions.

While monitoring and IPM protocols are essential, I am particularly interested in the curative actions that can be implemented when an active infestation is detected:

  *   How do you treat natural vegetated scenery in situ when the diorama cannot be moved (e.g. elements permanently fixed to the background, large or fragile structures)?
  *   Have you used anoxic, thermal, or chemical treatments, and if so, which methods have proven suitable and safe for mixed materials (organic + plastics)?
  *   What cleaning strategies do you recommend for dense or complex displays (numerous leaves, large volumes), where mechanical access is limited?
  *   Additionally, for dioramas that include plastic vegetation, how do you monitor and manage VOC emissions (preventive measures, filtration, adsorption materials, ventilation strategies, etc.)?

If available, could you share documented protocols, case studies, or practical recommendations, including successes, limitations and specific precautions?

Any experience or references would be greatly appreciated to help inform an ongoing conservation project.

Thank you very much in advance for your feedback,
Best regards,

Marion Billot
