Abstract

The potential of KLP+ traps baited with dual (pheromone and floral) lures (Csalomon®, Plant Protection Institute, CAR HAS, Budapest, Hungary) as a new tool for detection and monitoring of the Western corn rootworm, Diabrotica virgifera virgifera, was tested in 2015 and 2016 in Bulgaria. Four locations were chosen: Knezha (northwestern Bulgaria), Lozitsa village (north-central Bulgaria), Sofia (western Bulgaria), and Plovdiv (southern Bulgaria). D. v. virgifera was recorded in Knezha, Lozitsa and Sofia. The traps showed very high efficiency at different population densities of the pest. During our investigation, captures of D. v. virgifera adults were detected from the middle of July until the middle of September. The peak catches of the pest were registered at the end of July - the beginning of August in Knezha and Lozitsa, and in August in Sofia. In Knezha, the captures of beetles were influenced strongly by the local climatic factors - negatively by the air humidity in August 2015, and positively by the temperature variables in July 2016 (soil temperature) and August 2016 (air and soil temperatures).
