Computergestützte Identifikation - ein Update dichotromer Bestimmungsschlüssel oder doch mehr? - Beispiel: Fransenflügler (Insecta: Thysonaoptera, Thripse).

Abstract

About 5500 species of thrips are currently recognized worldwide and approx. 100 to 150 species are classified as economic importantly. There are now about 10 dangerous species of thrips known to carry Tospoviruses and damage a wide range of plants. Their identification represents primarily a challenge due to the described situation of taxonomic research for future generations in Europe. A possible way of the preservation of the taxonomic knowledge of the still available experts consists in the construction of suitable identification software into combination with effective molecular techniques for species diagnostics. Within the order Thysanoptera the identification software package LucID2.21 and the analysis of the rDNA (ITS-RFLP) lead fast to an exact diagnosis of pest thrips. The processing of the molecular results (primer pair, restriction enzyme, DNA product and fragment lengths) is carried out online with the help of a database (SQL & PHP).
