ABSTRACT

Modified sticky Delta traps and PAL CSALOMON® traps, unbaited or baited with synthetic aggregation pheromone of Sitona lineatus (L., 1758), 4-methyl-3,5-heptanedione, were used for studying the species spectrum of Sitona (Coleoptera: Curculionidae) weevils in alfalfa fields in the regions of Sofia, Plovdiv and Pazardzhik in 2007 and 2008. Several Sitona species, all known as pests on leguminous crops in Bulgaria, were caught. Modified sticky Delta traps baited with 4-methyl- 3,5-heptanedione caught significantly higher number of Sitona weevils than the unbaited traps.
