The first record of Echinothrips americanus Morgan in Slovenia

In 2001 Echinothrips americanus Morgan was first recorded in Slovenia. The thrips was first recorded in Europe in 1989, but did not begin to spread to a greater extend until 1993. This polyphagous pest is believed to cause direct damage, especially on the leaves of its host plants. The present contribution describes genetic structure of Echinothrips americanus Morgan rooting in polymorphism of the ITS1-5, 8S-ITS2 region of the ribosomal DNA. Echinothrips americanus Morgan is less resistant to insecticides and its ability to inhabit new areas is smaller, compared to the Western flower thrips (Frankliniella occidentalis [Pergande]). It can be concluded that its economic importance in the future will not reach that of the latter. We give a detailed description of the species, its geographic distribution, and deal with its host plants as well as bionomics and its potential natural enemies.
