Aak, A., B. a. Rukke, A. Soleng, and M. K. Rosnes. 2014. Questing activity in bed bug populations: male and female responses to host signals. Physiological Entomology doi: 10.1111/phen.12062.

Sex differences in bed bug behavioral responses to a stimulus (human host or carbon dioxide gas) were observed. Compared to males, female bed bugs responded more strongly to the human host signal, were more active while acclimating to a new environment, had quicker responses after feeding, and were exposed for longer periods of time during the day.
