The invasive leaf miner Phyllonorycter robiniella feeding on black locust, Robinia pseudoacacia, in Central Europe (Lepidoptera: Gracillariidae)
Entomologia Generalis 28 (3), 193-200
Abstract: The phenology of Phyllonorycter robiniella (Clemens 1859) was determined during the vegetative periods of 2002-2004 in the city of Marburg, Germany. Controls and collections were conducted at several study sites on leaves of black locust, Robinia pseudoacacia Linnaeus 1753, on a weekly basis. Oviposition of the moths took place in late June after completion of the flowering of the trees. Throughout the study three generations were completed in total. The duration of each generation differs. In 2003 and 2004 a forth generation started in autumn but could not be finished until abscissicion of the leaves. Mortality factors were parasitation during summer, predation by native birds during autumn, and abiotic conditions during winter. Autumn and winter mortality is assumed to be high as every spring low infestations of the trees and every autumn high infestations of the trees were found. Using the data of Phyllonorycter robiniella some properties of successful neozoa in Europe are pointed out.
