Adventitious leaf miner Parectopa robiniella Clemens, 1863 and Phyllonorycter robiniella Clemens, 1859 on a black locust tree in the Kharkiv region
The locust digitate leaf miner (Parectopa robiniella Clemens, 1863) is a native species of North America and, in the 80s, it spread to Italy, Slovenia, Croatia, Austria, Slovakia, Romania, Hungary, and Ukraine. Black locust leaf miner (Phyllonorycter robiniella (Clemens, 1859)) is also of North American origin. In 1983, the black locust leaf miner was discovered in Switzerland, in 1988 in France, Germany, Italy, in 1990 in Austria, in 1992-in Slovakia, in 1994 in Slovenia, in 1996-in Hungary, 1999 in the Netherlands, in 2003-in Bulgaria. Currently, both types of locust leaf miners are distributed in 19 European countries. In Ukraine, these species appeared relatively recently and are not sufficiently studied. We have studied some bioecological peculiarities of the locust digitate leaf miner and black locust leaf miner under conditions of Kharkiv region: the density of mines of the black locust leaf miner population, pieces/leaf, the dynamics of flight, population of black locust leaves.
