“…The sleep behavior of honey bees has been studied both in the natural context of the colony (Kaiser, 1988;Klein and Seeley, 2011;Klein et al, 2008;Klein et al, 2010) and in detailed laboratory studies (Eban-Rothschild and Bloch, 2008;Kaiser, 1988;Sauer et al, 2003). Honey bees exhibit all three behavioral characteristics of sleep: a period of quiescence (Eban-Rothschild and Bloch, 2008;Kaiser, 1988;Sauer et al, 2003;Sauer et al, 2004), an increased response threshold (Eban-Rothschild and Bloch, 2008; Kaiser, 1988;Kaiser and Steiner-Kaiser, 1983) and a homeostatic regulation mechanism (Klein et al, 2010;Sauer et al, 2004). In honey bee foragers, as in mammals and flies, sleep deprivation impairs learning and memory processes (Beyaert et al, 2012;Hussaini et al, 2009;Klein et al, 2010), and forager bees induced to learn novel navigational tasks sleep longer than control bees (Beyaert et al, 2012).…”
