Random collection of true bugs (Heteroptera) by Csalomone VARb3 funnel traps at the Jazbina science education station in Zagreb

During the growing season of 2008 Csalomon® VARb3 funnel traps were used for the monitoring of CETONINAE species. The traps were baited with synthesized scent of flowers and ornamental fruit plants. Traps varied in the color of attractive vane (yellow, blue and a combination of these two colors). Experiment was conducted in a mixed plum and cherry orchard at a research and educational station Jazbina in Zagreb. Orchard is surrounded by the oak trees and ground cover is dominated by native vegetation. Among the primary CETONINAE target species, a total of 108 true bugs (Heteroptera) were caught on a random basis. The traps were checked 14 times in 2008, starting on April 19, until August 21. The taxonomic identification was done following the Stichel keys. On the overall, 40 species of Heteroptera belonging to 12 families (TINGIDAE, NABIIDAE, ANTHOCORIDAE, REDUVIIDAE, MIRIDAE, LYGAEIDAE, BERYTIDAE, ALYDIDAE, COREIDAE, RHOPALIDAE, PLATASPIDAE and PENTATOMIDAE) were found. The frequency of Heteroptera was calculated according to Balogh and the degree of frequency was calculated according to Tischler. According to the degree of frequency test, 36 species of true bugs were characterized as accidental species and 4 were characterized as accessory species. Analysis of the catch frequency by Csalomon® VARb3 funnel traps has shown that these traps although not intended for hunting bugs can serve as an additional tool in the monitoring of Heteroptera species.
