• Plant waxes are complex mixtures of long-chain aliphatic and cyclic hydrocarbon compounds with different functional groups [10]. Typical wax components are fatty acids, alcohols, ketones, aldehydes, and triterpenes, but the exact wax composition is species- and organism-specific [11]. The waxes are

• taken for chemical analysis. The volumes of the aliquots were reduced to 200 µL at 70 °C under a stream of gaseous nitrogen. To ensure that the wax composition did not change due to the evaporation process, the chemical composition of the wax coating of the artificial surfaces (1400 µg) was analyzed too

For the extraction, the wax leaves were dipped in chloroform at room temperature for 60 s. The wax composition was analyzed by gas chromatography–flame ionization detection (GC–FID
