Cover Picture . Tenebrio molitor and Leptinotarsa decemlineata were sprayed with insecticides containing the active substances cyfluthrin and deltamethrin ( T. molitor ), and thiamethoxam and acetamiprid ( L. decemlineata ). For the analysis of volatile compounds of insects, solid‐phase microextraction (SPME) followed by gas chromatography (GC) coupled with mass spectrometry (MS) were used. Alkanes, aldehydes, ketones, esters, terpenes and fatty acids were identified in the analyzed samples of insects. Changes in the composition of volatile insect compounds were found before and after the application of insecticides. The content of volatile compounds differed between the time elapsed since the application of the insecticide and showed variability depending on the active substance contained in the insecticides, as reported by Wojciechowska and Gołębiowski in their full paper at 10.1002/cbdv.201900743.
