The Feeding Effect of Polyphenolic Compounds on the Colorado Potato Beetle [Leptinotarsa decemlineata (Say)]
Colorado Potato Beetle, Leptinotarsa decemlineata (Say) is a serious pest of potato plants and devastates additional crops such as eggplant, tomato, pepper, and tobacco by its voracious feeding. Plants of the Lamiaceae family produce a large number of polyphenols with insecticidal activity. In this study we tried to identify if some of these compounds could be used as antifeedants and if there ...
متن کاملIdentification of Differentially Expressed miRNAs in Colorado Potato Beetles (Leptinotarsa decemlineata (Say)) Exposed to Imidacloprid
The Colorado potato beetle (Leptinotarsa decemlineata (Say)) is a significant pest of potato plants that has been controlled for more than two decades by neonicotinoid imidacloprid. L. decemlineata can develop resistance to this agent even though the molecular mechanisms underlying this resistance are not well characterized. MicroRNAs (miRNAs) are short ribonucleic acids that have been linked t...
متن کاملSuppression of Colorado Potato Beetle, Leptinotarsa decemlineata (Say), (Coleoptera: Chrysomelidae) Populations with Antifeedant Fungicides
Laboratory, small-field plot, and commercial-scale experiments were completed, using Connecticut, Rhode Island, and New York Colorado potato beetle, (CPB) Leptinotarsa decemlineata (Say), populations to determine if "antifeedant fungicides" might reduce the suitability of potato for CPB while simultaneously protecting potato from early and late blight. In the laboratory. fungicides formulated f...
متن کاملArtificial diets for rearing the Colorado potato beetle, Leptinotarsa decemlineata
Colorado potato beetles have been reared successfully through 12 generations on artificial diets containing either 2.5% potato leaf powder or 2.5% lettuce leaf powder/0.75% potato leaf powder. For all but one of the treatment groups, the mean duration of each of the four larval stages was between 0.8 and 1.5 days longer than the durations exhibited by control beetles that had been fed on potato...
متن کاملRNA Interference as a Tool for the Functional Analysis of Genes in the Colorado Potato Beetle, Leptinotarsa decemlineata (Say)
RNA interference (RNAi) is a naturally occurring phenomenon in eukaryotes in which a double-stranded RNA (dsRNA) suppresses the expression of a target gene. RNAi has markedly changed the way in which functional genetics studies are performed, especially in non-model organisms. In insects, the efficacy of RNAi is influenced by several factors, including the species and the methods of dsRNAs deli...
