Strauzia longipennis in Germany

The species was observed for the first time in the Palaearctic Region in 2010 in Germany; two females walked on the leaves, often on lower surface, and oviposited into the stem on a young sunflower plant ( Helianthus annuus ) in a flower bed; photographs were taken and posted on the diptera.info website ( Beuk, 2010) and identified by SVK as Strauzia longipennis (Wiedemann, 1830) based on photos on the site or sent by e-mail ( Brückner & Korneyev, 2010). Followed this publication, intensive survey begun and the plants in this locality were eradicated.

According to Baufeld et al. (2020), Strauzia longipennis belongs to the category of non-European tephritid flies, which are regulated as quarantine pests of the EU; the species was included in the EPPO quarantine pest list, but was subsequently removed

In 2012 / 2013, a winter with severe frost led to a significant decline of the outdoor population in Brandenburg, while the population continued to exist in Berlin and surroundings, but no signs of further natural spread have been detected in Brandenburg in the last 10 years; the authors consider the probability of natural spread from the infested area to be low, as the population density in outdoor sunflower fields is very low; no infestations of Jerusalem artichoke are known in Europe.
