Abstract

The leaf miners of black locust.

Abstract

In the last 35 years, the black locust [Robinia pseudoacacia] trees in Europe have been invaded by two leaf miner species (Parectopa robiniella and Phyllonorycter robiniella) from North America. Parectopa robiniella came in Europe (Italy) during 1970, and Phyllonorycter robiniella in Switzerland during 1983. The species recorded a spreading rate of approximately 100 km/year, both of them reaching Romania after approximately 18 years from their arrival in Europe. Parectopa robiniella has particularly infested Romanian forest cultures severely causing important disturbances.
