Photoperiodic responses of Sahelian malaria mosquitoes Anopheles coluzzii and An. arabiensis

Parasites & Vectors

Table 1 Predicted and observed responses of females Anopheles coluzzii and An. arabiensis to simulated dry season as opposed to wet season conditions in Experiment 1 (photoperiod alone) and Experiment 2 (photoperiod and temperature)

Trait	Predicted: dry vs wet conditions		Observed: dry vs wet conditions

Notes: Prediction is bold reflect strongest predictions based on previous studies in the field. Checkmarks identify results of the experiment that are consistent with aestivation in An. coluzzii but not in An. arabiensis. Responses that have partly matched predictions were marked with a ‘^*’
