T1 - The bacterial microbiome in spider beetles and deathwatch beetles N2 - The beetle family Ptinidae contains a number of economically important pests, such as the cigarette beetle Lasioderma serricorne, the drugstore beetle Stegobium paniceum, and the diverse spider beetles. Many of these species are stored product pests, which target a diverse range of food sources, from dried tobacco to books made with organic materials. Despite the threat that the 2,200 species of Ptinidae beetles pose, fewer than 50 have been surveyed for microbial symbionts, and only a handful have been screened using contemporary genomic methods. In this study, we screen 116 individual specimens that cover most subfamilies of Ptinidae, with outgroup beetles from closely related families Dermestidae, Endecatomidae, and Bostrichidae. We used 16S ribosomal RNA gene amplicon data to characterize the bacterial microbiomes of these specimens. The majority of these species had never been screened for microbes. We found that, unlike in their sister family, Bostrichidae, that has two mutualistic bacteria seen in most species, there are no consistent bacterial members of ptinid microbiomes. For specimens which had Wolbachia infections, we did additional screening using multilocus sequence typing and showed that our populations have different strains of Wolbachia than noted in previous publications.

However, human culture has also always widely utilized them as central characters in philosophy, in classic and modern world literature, in music and arts, and much more. This article will highlight some recent exploitations of pest insects in Cultural Entomology. It will provide examples of pieces of art and ephemeral displays with clothes moths and termites as protagonists. The insects´ destructive nature on textiles or wood was turned around to a process of creation with aesthetic, philosophical and metaphoric messages, or simply for unique ways of entertainment.

Die Anwendung von Holzschutzmitteln zum Schutz verbauten Holzes ist dabei eine Möglichkeit. Voraussetzung für den Gebrauch von Holzschutzmitteln ist deren Zulassung nach Biozidgesetz. Der Vortrag beschreibt die Vorgehensweise bei der Wirksamkeitsbewertung von Holzschutzmitteln im Rahmen der europäischen Biozidzulassung. Die Wirksamkeitsbewertung erfolgt durch biologische Prüfungen anhand von europäischen Normen getrennt nach Zielorganismen. Je nach späterer Gebrauchssituation des mit Holzschutzmitteln behandelten Holzes sind definierte Alterungsverfahren nach Norm der eigentlichen biologischen Prüfung vorzuschalten. Das Prüfergebnis des widerstandsfähigsten Organismus legt die zum Schutz des Holzes notwenige Konzentration und Einbringmenge des Holzschutzmittel fest.
