Dear PestListers,
as there were no answers to the mails of Riet, Ashley and mine regarding the topic of Lyctus sp. I am interpreting that wood boring insects are not of interest in this group. And as I don’t want to bother people with mails and files, I will not send the photographs to the complete group. If someone is interested - please get in touch off-list. 😊 Best wishes Antje A.

November 2024 14:59 An: pestlist@googlegroups.com Betreff: Lyctus sp. Dear Riet, Dear Ashley, Apart from the somehow strange coincidence that two cases of a Lyctus infestation are reported just within a week 😊 - may I address some questions to your cases? Do you have the possibility to provide us with a photograph of each object and a picture of the damage? And Riet, do you have any information upon the place of production or when the mask entered your collection? I had a similar case last year with a private costumer’s picture frame. (I am attaching for the moment a photograph of the picture in its old frame.) Treatment: The infestation was so intense that the frame had to be discarded / the picture had to be reframed. Timber age and place of frame-production: As I remember the infested frame was not that old and was most probably produced in Germany / bought from a German frame-maker. (I will get in contact with the customer again and try to figure out the details.) Upon the wood species (as Stephan pointed to this): (I am not a botanist (and therefore not able to differentiate between all approx.. 60.000 wood species in the world) but I am a cabinetmaker and as wooden objects conservator have been trained in the Munich Wood Research Institute by Dr. Grosser for identifying the approx.. 100 wood species found in middle-European furniture = middle-European species and species from colonial areas). What I can say based on this education is the following. related to the frame context: * It has to be a modern commercial wood species (EN 13566) related to a macroscopic investigation (colour, density, wood texture, fungal decay type …): * it is a hardwood species * obviously not middle-European origin * most probably: Triplochiton scleroxylon (“Abachi” in german) (Attention: there was no micro-anatomical identification carried out!) Damage: As the customer was so kind to send me a part of the old frame I will prepare some photographs at the weekend and send them next week. Beetle species: It was not a topic to identify the species as it was clear that the frame will be replaced. But I have collected an adult and will make some photographs at the weekend as well. This might be a Lyctus sp. as well. Best wishes Antje A. Zygalski Conservation Co.
