| Abstract: | In the period from 1986 to 1988 the synthetic sexual pheromone ofTortrix viridana L. and different types of traps were investigated in Slovakian oak forests. The dependence of male numbers per trap on the forest type groups was studied parallely as well as the attraction of pheromones for other moth species was tested, too. The pheromon TV83 (Z11-14: Ac+Z11-14: OH, 9∶1, 50 μg) and unsticky plastic trap with DDVP called “Mushroom” showed the highest effectivity. The pheromon monitoring confirmed the theory that the pest prefers the biotops with dominance ofQuercus pubescens andQ. robur. The optimum of pest was bound to forest type groups Carpineto-Quercetum und Ulmeto-Fraxinetum carpineum. The minimal number of other moth species was observed in traps with pheromons TV83 (?SFR) and Hoechst (FRG). |
