A key to the second instar larvae of 130 species of Thripidae occurring in the Western Palaearctic Region is presented, covering 40% of the total number of Thripidae species from that region.Additionally some species of quarantine interest are included in the key: Scirtothrips aurantii Faure, S. citri Moulton, S. dorsalis Hood, Selenothrips rubrocinctus (Giard), Stenchaetothrips spinalis Reyes, Taeniothrips eucharii (Whetzel) and Thrips parvispinus Karny.Sampling and preparation techniques of second instar larvae of Thysanoptera are given.In contrast with adults, second instar larvae provide reliable distribution and host plant data for species.Additionally, larvae are often encountered during import inspections of plant products and their identification enhances the efficiency of quarantine measures for harmful species.
