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.

A new tool for detection and seasonal monitoring of Oxythyrea funesta (Poda), floral baited colour traps, a commercial product of Plant Protection Institute, Center for Agricultural Research, HAS, Budapest, Hungary, was used for studying the distribution and patterns of seasonal appearance of the pest in eight sites in Bulgaria in 2009 and 2010. The most numerous catches of O. funesta were recorded in Plovdiv in both years and in Troyan in 2010. Catches ranging from 21 to 52 beetles were recorded also in Dryanovo, Karnobat, Kyustendil, Petrich and Troyan in 2009; Knezha and Troyan in 2010. In 2009 the earliest catches of O. funesta were recorded in Petrich for the period April 12 - April 20. In 2010 the first catches were recorded in Knezha for the period April 16 - April 22. The latest catches for the two years were recorded on September 6, 2010 in Troyan. The traps showed low selectivity especially in sites where another cetoniid pest, Tropinota (Epicometes) hirta (Poda), attracted to the same traps, occurred.

The potential of commercially available light blue VARb3k traps and baits for T. hirta (Csalomon®, Plant Protection Institute, Budapest, Hungary) as a new tool for detection and describing the seasonal flight patterns of Tropinota (Epicometis) hirta (Poda) was proved in eight sites in Bulgaria in 2009 and 2010. The traps showed very high efficiency in both cases of high and low population level of the pest. Significant catches of T. hirta were recorded in Dryanovo, Kamobat, Knezha, Kyustendil, Petrich and Plovdiv. As a whole the beetles appeared in the very end of March - beginning of April and reached their peak flight in the second half of April - beginning of May; catches were recorded up to the middle of July. The bait/traps system used in our field work showed very high species selectivity. In nine out of ten cases the catches of T. hirta exceeded 90% and in six of these this percent was equal or more than 99%, including Petrich where only T. hirta were caught in 2009.
