This research demonstrates an effective dna extraction protocol for museum insect specimens, highlighting optimal barcoding and ecological connections.
DNA technologies have many advantages for biomonitoring and biodiversity analyses, but these depend on the availability of relevant reference DNA barcodes. To be most useful, a DNA barcode should be linked to a taxonomic name, which can in turn be connected to ecological information. This linking can be achieved by DNA barcoding of taxonomically identified specimens. Museums are a promising source of such specimens, but the DNA in museum specimens is often degraded, necessitating carefully optimised DNA extraction methods. In this issue of Molecular Ecology Resources, Holmquist et al. (2025) present a DNA extraction protocol for museum insect specimens, using in‐house formulated Solid Phase Reversible Immobilisation (SPRI) beads. The authors carried out several experiments with statistical evaluation to determine optimal DNA extraction parameters, before testing the protocol on a large and diverse pool of museum‐held insect specimens. The result is a low‐cost and effective DNA extraction protocol for diverse museum insect specimens.
