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 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 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 کاملBIOLOGICAL CONTROLÐMICROBIALS Beauveria bassiana Horizontal Infection Between Cadavers and Adults of the Colorado Potato Beetle, Leptinotarsa decemlineata (Say)
The behavior of adult Colorado potato beetles (Leptinotarsa decemlineata) in the presence of Beauveria bassiana sporulating on cadavers was studied to determine the likelihood of disease infection as beetles emerge from the soil and colonize host plants. In 2001, the movement of single adultColoradopotatobeetleswasmonitored in arenas containing infective cadavers in differing spatial patterns b...
