Abstract
A set of mitochondrial COI primers has been studied by genomic PCR and many primer combinations shown to work universally well across Insect a. They are able to amplify various amplicons with different variabili ty which enables the selection of a particular amplicon as a suitable DNA marker for a project. The potential usefulness of different amplic ons is examined, with analysis on published study cases employing thes e regions. With respect to their variability, amplicons UEA5/UEA6, UEA 7/UEA8 and UEA5/UEA8 could be useful for low- to mid-level phylogeneti c analysis, i.e. from species, genus to perhaps family level depending on taxa involved. UEA5/UEA6 will be too conserved for intraspecific s tudies. Amplicons UEA3/UEA4 and UEA9/UEA10 would be better suited to l ow-level phylogenetic investigations, such as analysis of relationship s among closely related species and population genetic studies. Howeve r, these guidelines should not be over-generalized for the reasons giv en. Amplification conditions of various primer combinations, and gener al problems in the use of conserved PCR primers are discussed.
