Dasineura gleditchiae (Osten Sacken, 1866) (Diptera: Cecidomyiidae), honeylocust pod gall midge: a new invasive species in Slovenia.


A strong attack of honeylocust pod gall midge (Dasineura gleditchiae) on honeylocust (Gleditsia triacanthos) in Ljubljana, it's surrounding area and in Maribor was found in May 2010. The insect was found on all surveyed locations but the attack was stronger on "Sunburst" horticulture variety than on seed-grown trees. From the intensity of the infestation and the overall spread of the honeylocust pod gall midge, it is concluded that it was introduced some years before. At the end of May, the midge finished its first reproduction cycle in this year and adults massively emerged from the pods. The characteristics of morphology, life cycle and possibilities of suppression of honeylocust pod gall midge area described. This is the first report of Dasineura gleditchiae from Slovenia.
