The yellow-legged hornet, Vespa velutina, was accidentally introduced from Southeast Asia and then invaded France and Korea over the last 10 years. Since its introduction, its predation on honeybee colonies has rapidly become an economic problem in invaded countries. Using mitochondrial cytochrome C oxidase and 22 nuclear microsatellite loci, we showed that(More)
Since its introduction in France 10 years ago, the yellow-legged Asian bee-hawking hornet Vespa velutina has rapidly spread to neighboring countries (Spain, Portugal, Belgium, Italy, and Germany), becoming a new threat to beekeeping activities. While introduced species often leave behind natural enemies from their original home, which benefits them in their(More)
Coloration of stinging insects is often based on contrasted patterns of light and black pigmentations as a warning signal to predators. However, in many social wasp species, geographic variation drastically modifies this signal through melanic polymorphism potentially driven by different selective pressures. To date, surprisingly little is known about the(More)
This paper presents an innovative technique to efficiently develop hardware and software code generators. The specification model is first converted into its equivalent data structure. Target programs result from a set of transformation rules applied to the data structure. These rules are written in a textual form named Script. Moreover, transformations for(More)
Real time scheduling algorithms provide a mean to schedule tasks on processor such that real time constraints are guaranteed. Fixed priority real time scheduling algorithms have low runtime complexity and their behaviour can be categorized a prior but they do not support dynamic systems very well. A transient overload in dynamic priority scheduling(More)
