- Abstract
Galls caused by seven species of European cecidomyiids were found on leaves of Populus tremula. native to Europe, on P. tremuloides, native to North America, and on leaves of their hybrids planted in southern Bohemia. Some galls on hybrids had unusual shapes. Factors influencing the process of establishment of gall midges on new plantings of these trees and their hybrids are discussed. The horizontal and vertical occurrence of five gall midge species occurring abundantly on P. tremula in the Czech Republic are described. Some gall midge species associated with P. tremula are abundant in central Europe but they do not cause significant injury to the trees. Prodiplosis morrisi caused severe injury to poplars in Canada. European species Contarinia populi occupies a relative small distribution area in central Europe, Harmandia tremulae extends up to the Ural Mountains, H. cavernosa, H. globuli, H. populi and Dasineura populeti are spread up to central Siberia and Contarinia petioli is broadly distributed from Europe to the Far East.
