The effects of citrus limonoids, applied topically to potato ( Solanum tuberosum L. var. ‘Katahdin’) foliage, on Colorado potato beetle ( Leptinotarsa decemlineata (Say) ( Chrysomelidae ) larval development, growth, and survival were quantified in laboratory assays and a small‐plot field test. In laboratory assays, survival, development rate, and body weight decreased with increasing limonoid concentration, however these measures of larval response did not significantly differ among varying periods of limonoid exposure (three, six, or nine days). Significant limonoid application concentration and frequency effects on survival, development rate, and defoliation were observed in the field test. These results indicate the potential utility of lethal and non‐lethal effects of citrus limonoids for management of the Colorado potato beetle.
