Three-years monitoring (1996 –1998)of the leafminer moth Leucoptera scitella Zell was organi- zed in the apple orchard of the Fruit-Growing Institute,Plovdiv,Bulgaria.Sex pheromone traps with Hunga- rian 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.

Field investigations with CSALOMON® floral-chemical baited color traps for scarab beetles (Coleoptera: Scarabaeidoidaea) were organized in eight sites in different regions in Bulgaria during 2009–2010. As a result data about distribution and seasonal flight were obtained for the target species Cetonia aurata L. and Protaetia cuprea (Fabricius) and two other non-target species, Valgus hemipterus L. and Blitopertha lineolata (Fischer von Waldheim). Catches of C. aurata were recorded in all of the sites where observations were organized but the number of the beetles caught was relatively low. The earliest catches of this pest were registered in the middle-end of April and the latest ones in early August. Single catches of P. cuprea, not allowing doing conclusions about seasonal flight for this species, were recorded only in Dryanovo, Knezha, Plovdiv and Troyan. Catches of V. hemipterus, were registered in all of the sites with the exception of Petrich. The flight period of this species, as established by catches in the traps, was middle-end of April — early June. Significant number of B. lineolata was caught in Dryanovo in 2009 and single catches in Plovdiv in 2009 and Kyustendil in 2009 and 2010. The earliest catches for the two years in Dryanovo were registered in the middle-end of May and the latest ones in the middle of June. This is the first report about floral-chemical attractant for this species. For all four species the relative catches in traps for C. aurata/P. cuprea, Tropinota (Epicometis) hirta (Poda) and Oxythyrea funesta (Poda), operating simultaneously in the investigated sites, were presented and analyzed.
