The genetic basis of German cockroach bait aversion
  Key Words  
  Behavioral resistance, glucose aversion, baits, genetics

  Behavior is modulated by both learned and innate factors, and the heritability of behavior has been documented in several arthropod taxa. Certain behaviors have evolved following selection with toxicants. One such behavior that is adaptive to the German cockroach is glucose aversion, which is controlled by a single major gene. German cockroaches with this trait survive in the presence of baits containing glucose. I will provide a general overview of the genetics of taste in arthropods within the framework of plant-herbivore coevolution in an effort to understand current bait aversion issues as well as anticipate how others may arise.
