The Carlos Ritter Natural Science Museum at the Federal University of Pelotas UFPel, has a considerable entomological collection (insects) in “longterm exposure” in its exhibition spaces. This intervention is justified by the historical value of the collection (such as the collections referring to Professor Dr. Ceslau Maria Biezanko and the mosaics made by Mr. Carlos Ritter). This article aims to report the processes and methodologies used in the restoration of this collection. The procedures and processes used in this collection were based on the same ones used in entomological collections of scientific status. Through preliminary visual survey procedures, the level of the entomological elements (specimens) degradation was established. Based on this, a series of mechanical and chemical interventions were used to systematically update specimens (taxonomic revision), the collection of specimen shingly degraded by biological agents such as fungi, small beetles, moths, cockroaches, etc. Employment of chemical preservatives and even replacement of new specimens of the same species (in the case of materials that cannot be restored). In addition, special attention was paid to the data referenced in the collection and identification labels that might have been deteriorated by the action of time. All entomological rusty pins were replaced by new pins. The set of procedures resulted in a collection up dated zoologically and in a position to serve the academic and lay public.
