Three-years monitoring (1996 –1998) of the leafminer moth Leucoptera scitella Zell was organized in the apple orchard of the Fruit-Growing Institute, Plovdiv, Bulgaria. Sex pheromone traps with Hungarian caps (Plant Protection Institute, Hungarian Academy of Sciences) were used for first time in this country. As a result, three full generation of the pests were established in all three years and a partial one in 1996 and 1998. The beginning and the end of the first generation were also well defined by the catches in the pheromone traps. However, an overlap of the second and the third on the one hand and the third and the fourth on the other, was observed in all three years.The time of the first catches from the first generation varied from April 9 to April 22. The second and third generation began in the second decade of June and second decade of July, respectively. Chemical treatments seem to have no significant effect on the catches in the pheromone traps.
