The diversity of species of Ceutorhynchinae captured in traps in the region of Sofia, Bulgaria.

Sticky PALs and “hat” KLP+ traps (CSALOMON ® ) were used for studying species diversity of Ceutorhynchinae weevils (Coleoptera Curculionidae). The catches in transparent and yellow, and in unbaited and baited with 2-phenylethyl isothiocyanate traps were compared. A total of 17 species from the subfamily Ceutorhynchinae were trapped in Sofia Basin area in 2006 and 2007. They belonged to the six genera: Amalus, Ceutorhynchus, Microplontus, Rhinoncus, Sirocalodes and Thamiocolus. Several economic pests on cruciferous crops including Ceutorhynchus pallidactylus (Marsham), Ceutorhynchus obstrictus (Marsham), Ceutorhynchus napi Gyllenhal, Ceutorhynchus picitarsis Gyllenhal and Ceutorhynchus erysimi (F.), were found in low numbers. Fourteen weevil species are newly recorded for the Sofia Basin area. The most abundant species was Ceutorhynchus typhae (Herbst). Significantly high number of adults of this species was found in yellow sticky traps. The number of the beetles caught was not affected by the presence or absence of the chemical cue, 2-phenylethyl isothiocyanate. We suggest that yellow PALs traps can be effective tools for faunistic researches on Ceutorhynchinae weevils in various habitats and for detection and seasonal monitoring of harmful Ceutorhynchus spp.
