Insect collections and DNA analyses: how to manage collections?

Numerous papers have been recently published regarding DNA studies of museum insect specimens. Despite the great enthusiasm for such analyses, there continues to be a potential conflict between specimen maintenance and their use for experimental procedures, since DNA extraction methods are sample destructive. This created a strong limitation for studies on museum specimens, making so impossible to work on rare or irreplaceable species. However, new methods for improving insect preservation have been recently published, together with new procedures for performing less destructive DNA extractions that combine specimen maintenance and DNA extraction.
