ABSTRACT. Semi-synthetic ecdysteroids synthesized from 20-hydroxyecdysone isolated from Serratula coronata were tested on adult Colorado potato beetles. Four out of the ten compounds stimulated the viability of the insects that developed on insecticide-pretreated Solanum tuberosum plants. Pretreatment of the beetle adults with the ecdysteroids promoted selective mitigation of the toxic effect of fipronil and bensultap on the insects.
KEY WORDS: ecdysteroids, 20-hydroxyecdysone, 9б-hydroxy-5б-ecdysteroids, Leptinotarsa decemlineata, protective effect.
