The antifeedant activity of lactones with di- and trimethylcyclohexane system was assessed in choice and no-choice bioassays against Leptinotarsa decemlineata and Alphitobius diaperinus larvae and beetles. The results showed that feeding deterrent activity depends on the structure of the tested compounds. Additional methyl group in the molecule of some compounds influences their activity increase or changes their properties from attractant to deterrent ones. The present results also demonstrate the species and developmental stage dependence of antifeedant activity
