Fig 1.
Concentration–response curves for the inhibition of antennal response by thymol and carvacrol in Ateuchetus cicatricosus.
Bars represent ± SD (n = 12). Statistical results of the effect concentrations (IC50) for both phytochemical compounds are provided in Table 1. The smaller graph above shows the positive relationship between the concentrations of thymol and carvacrol and the amount of each compound ingested at the individual level.
Table 1.
Concentrations of phytochemical compounds at which the antennal response of adults of Ateuchetus cicatricosus was inhibited by half (IC50) (95% CV intervals), calculated from dose‒response curves presented in Figs 1 and 2.
Fig 2.
Concentration–response curves for the inhibition of antennal response by cinnamaldehyde and garlic oil in Ateuchetus cicatricosus.
Bars represent ± SD (n = 12). Shaded areas represent the 95% confidence intervals of each model. Statistical results of the effect concentrations (IC50) for both phytochemical compounds are provided in Table 1. The smaller graph above shows the relationships between the concentrations of cinnamaldehyde and garlic oil and the amount of each compound ingested at the individual level.
Fig 3.
Antennal response (in mV) observed for 0.1, 1.0, 10.0, 100.0 and 1000.0 mg kg–1 thymol (THY), carvacrol (CVR) and NEXT ENHANCE 150 (NE150) compared to those observed for ivermectin at 100 μg kg–1 (IVM) (positive control) and for dung without any treatment (Control) (negative control).
Dunn’s multiple comparisons test showed significant differences only between the control and the ivermectin treatment (P < 0.01).

Antennal response (in mV) observed for 0.1, 1.0, 10.0, 100.0 and 1000.0 mg kg–1 cinnamaldehyde (CIN), garlic oil (GAO) and NEXT ENHANCE 300 (NE300) compared to those observed for ivermectin at 100 μg kg–1 (IVM) (positive control) and for dung without any treatment (Control) (negative control).
Dunn’s multiple comparisons test showed significant differences only between the control and the ivermectin treatment (P < 0.0001).
