The effect of conductor wires of different metals on the amount of honey bee (Apis mellifera; Hymenoptera: Apidae) venom collected and its chemical content

Researchers have been interested in honey bee, Apis mellifera L., venom for many years, but the previous studies focused mainly on its pharmacological properties and the factors affecting its production and chemical content were less well evaluated. This research aims to investigate the potential effect of the method of collecting bee venom on its chemical content. To achieve this, brass, steel, aluminium and copper wire conductors were used. This research was carried out at Van YYU Beekeeping Application and Research Centre, where the venom was collected dry on glass plates from 16 Caucasian F1 honey bee colonies. The quantity produced and its composition in terms of melittin, apamin and phospholipase A2 were determined after storage. Duncan and LSD Multiple Comparison tests on the amounts of venom collected using aluminium, copper, steel and brass wires for conducting electricity, revealed it was 21.03 ± 3.50, 15.08 ± 0.32, 22.38 ± 6.35 and 30.35 ± 3.66 mg, respectively. Although these values differed significantly (p < 0.05), the chemical content of the bee venom was the same. The colour of the venom was associated with the material of the electrical conductor used. It was concluded that it would be beneficial to carry out further studies using more colonies along with using residue analysis.
