Effects of Selection to Diflubenzuron and <i>Bacillus thuringiensis</i> Var. <i>Israelensis</i> on the Overwintering Successes of <i>Aedes albopictus</i> (Diptera: Culicidae)
<i>Aedes albopictus</i> is an invasive mosquito species responsible for local transmission of chikungunya and dengue viruses in Europe. In the absence of available treatments, insecticides-based control remains one of the most important viable strategies to prevent emerging problems. Dif...
