An entomopathogenic bacterium, Pseudomonas putida, from Leptinotarsa decemlineata
Th e Colorado Potato Beetle (CPB), Leptinotarsa decemlineata (Say) (Col.: Chrysomelidae), is a pre-eminent pest on solanaceous crops worldwide, and much research has focused on the diff erent components of its variable population dynamics. L. decemlineata has developed resistance to insecticides used for its control. Consequently, alternative methods are needed urgently for the control of this ...
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 کاملModeling Colonization of Overwintered Immigrant Leptinotarsa decemlineata (Coleoptera: Chrysomelidae)
Colonization of potato (Solanum tuberosum [L.]) Þelds by Colorado potato beetle, Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae), has often been recognized as a process that initially results in an edge-biased spatial pattern. We modeled this spatial process by measuring distance of immigration for individual overwintered adults.Distancewasmeasured to the nearest Þeld edge or to the...
متن کاملTemporal patterns of imidacloprid resistance throughout a growing season in Leptinotarsa decemlineata populations
BACKGROUND The Colorado potato beetle, Leptinotarsa decemlineata (Say), is a major agricultural pest of commercial potatoes. Pest managers use a combination of control tactics to limit populations, including multiple insecticides. Finding a window of insecticide susceptibility and understanding genetic responses to insecticide exposure during a growing season may provide novel management recomm...
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...
