Variation in Hsp70 Levels after Cold Shock: Signs of Evolutionary Responses to Thermal Selection among Leptinotarsa decemlineata Populations
Individuals of widely spread species are expected to show local adaption in temperature tolerance as they encounter a range of thermal conditions. We tracked thermal adaptations of the Colorado potato beetle (Leptinotarsa decemlineata) that invaded Europe within the last 100 years. It has occupied various conditions although, like the majority of invasive species, it lost a measurable amount of...
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 کاملMultiple evolutionary origins of knockdown resistance (kdr) in pyrethroid-resistant Colorado potato beetle, Leptinotarsa decemlineata
The Colorado potato beetle (CPB), Leptinotarsa decemlineata, is a serious agricultural pest that is difficult to control due to its rapid evolution of resistance to most insecticides. Knockdown resistance (kdr) has been identified as the chief mechanism of resistance against pyrethroid insecticides in CPB and is due to a single nucleotide polymorphism, L1014F, of the voltage-sensitive sodium ch...
متن کاملPatterns of variation in levels of hsp70 in natural rocky shore populations from microscales to mesoscales.
An important step in connecting the organismal response to thermal stress to patterns of community structure is determining at what scale discernable levels of variation are manifested. The temperature signal to which organisms may potentially respond varies at many spatial scales including microhabitat, tidal height, site and latitude. A number of studies have taken physiological assessment of...
متن کاملPatterns of Variation in Levels of Hsp70 in Natural Rocky Shore Populations from Microscales to Mesoscales1
SYNOPSIS. An important step in connecting the organismal response to thermal stress to patterns of community structure is determining at what scale discernable levels of variation are manifested. The temperature signal to which organisms may potentially respond varies at many spatial scales including microhabitat, tidal height, site and latitude. A number of studies have taken physiological ass...
