Quel niveau de résolution taxinomique nécessaire en entomologie forestière ?

Abstract : We discuss the necessary level of taxonomic resolution in the 4 objectives of forest entomology: assessing reliable estimates in biodiversity studies, interpreting lists of data in terms of ecology, monitoring pests and natural enemies for forest protection, detecting new invasive species. Because identifying many insects to species is difficult, requires expert training and is very time-consuming and, therefore, costly, there has been quite a lot of research on alternative techniques: (i) supraspecific approaches using coarser taxonomic resolution (identification to families, genera...), (ii) parataxonomical approaches distinguishing only morphospecies (or RTU, Recognizable Taxon Units) for Rapid Biodiversity Assessments (RBA), (iii) identification limited to certain species (signal, indicator, umbrella, flagship species). The development of collaborative networks, such as Internet databases of pictures and molecular data, is currently transforming the methodological landscape in insect taxonomy.
