Circadian rhythm of behavioural responsiveness to carbon dioxide in the blood-sucking bug Triatoma infestans (Heteroptera: Reduviidae)
The temporal modulation of the behavioural response to carbon dioxide and its chronobiological basis were investigated in larvae of Triatoma infestans. We analysed the orientation towards CO2 of insects kept under three different illumination regimes: (1) 12 h light/12 h darkness cycles (L/D), (2) c...

| description |
The temporal modulation of the behavioural response to carbon dioxide and its chronobiological basis were investigated in larvae of Triatoma infestans. We analysed the orientation towards CO2 of insects kept under three different illumination regimes: (1) 12 h light/12 h darkness cycles (L/D), (2) constant darkness (D/D) and (3) constant light (L/L). When maintained under L/D conditions, insects exhibited an oriented response towards airstreams added with 1500 ppm of CO2 during the first hours of the scotophase only. Bugs maintained under D/D also showed a positive orientation response towards CO2 during the first hours of the subjective night, while bugs kept under L/L did not show a rhythmic oriented behaviour. Thus, T. infestans displayed a daily rhythm of orientation towards CO2 (i.e. a potential food source) only at the beginning of the scotophase. The persistence of the rhythm under constant darkness reveals the existence of an endogenous circadian control of this behaviour. © 2003 Elsevier Ltd. All rights reserved. |
