The influence of secondary plant substances - glucosinolates, alkaloids and saponins on the food choice by Colorado potato beetle (Leptinotarsa decemlineata Say) was investigated. Choice and no-choice assay with potato (Solanum tuberosum L.) leaf discs were made. lnsects' feeding was decreased on leaf discs treated with tested substances and it depended on the concentration of used compounds. Saponins were the most active as antifeedants against Colorado potato beetle.
