| Abstract: | An overview of knowledge about the horse chestnut minerCameraria abridella Desch. & Dem. (Lep., Gracillariidae), a pest developing in leaf mines ofAesculus bippocastanum, spread gradually from the Ohrid-Lake (Macedonia) through Bosnia, Serbia and Croatia up to the central Europe (fig.). At present (1999) it occurs in northern Italy, Switzerland, Hungary, Czech and Slovak Republics, Austria, southern and central Germany and in southern Poland. Usually three, but up to five generations develop a year in central-European conditions.C. obridella develops also in leaf mines onAcer pseudoplatanus andA. platanoides. The parasitation is 1–8% and seems not to increase. Heavily attacked trees do not die; only rarely the dying of heavily damaged trees have been observed. Several insecticides may be used to control of this pest. The most successful was the growth-regulator Dimilin with active substance of Diflubenzurol. In the future it will be possible to control populations ofCameraria obridella by pheromones. The future development of this pest and its control is discussed. |
