Fig. 8: Amitraz targets the octopaminergic signalling in the malaria mosquito ear.

a Time series of the effects of different amitraz concentrations on the fibrillae erection of malaria mosquitoes. Almost 100 % of male mosquitoes erect their fibrillae upon amitraz exposure. Data are presented as mean values +/− SEM. b AgOctβ2 knockouts exposed to amitraz do not erect their fibrillae. Concentrations used based on⁸⁹. Samples sizes: time series experiments: control = 30; 0.025% amitraz = 10; 0.1% amitraz = 5; 0.4% amitraz = 20; amitraz exposure wt = 29; AgOctβ2 knockouts = 39.
