Abstract

The common bed bug (Cimex lectularius L.) (Hemiptera: Cimicidae) is an obligate blood-sucking insect that has been resurging in many countries. Researching this pest's behavior will help design more effective control methods. In this study, we evaluated the effect of feeding history and time elapsed from field collection on bed bug movement behavior and response to chemical lure or carbon dioxide stimulation in the laboratory. After CO2 was released, bed bugs unfed for 3 d began to return to harborages; in contrast, the ones unfed for 2 and 4 wk spent significantly more time outside their harborages during the first 1 h after than the 1 h before CO2 release. After CO2 release, there was an increase in activity (time spent moving outside harborage) in all bed bugs with different feeding history or time elapsed from field collection. During the 8-h observation period when CO2 was present, bed bug males unfed for 4 wk spent significantly more time exploring outside harborages than the ones unfed for 3 d, 1 wk, and 2 wk. Nymphs collected 1–2 wk and 1 yr ago spent significantly more time exploring outside harborages than the ones collected 43 yr ago. Bed bug's exploratory activity (the total percentage of bed bugs trapped in both baited and unbaited interceptors) was significantly affected by their time elapsed from field collection and their exploratory activity level was 1–2 wk > 6 mo > 5 and 43 yr. Both feeding history and time elapsed from field collection significantly affected bed bug movement, whereas bed bug's response to chemical lure or CO2 (the percentage of bed bugs trapped in the baited interceptor, summarized as the number of bed bugs trapped in the baited interceptor divided by the total number of trapped bed bugs in both baited and unbaited interceptors) was unaffected by the time elapsed from field collection.
