Fig. 2: Impact of mating harassment on feeding success in semi-field cages.
From: Mating harassment may boost the effectiveness of the sterile insect technique for Aedes mosquitoes
The box plots present median values and quartiles, whiskers the 95% percentiles and dots the individual data points. One-tailed pairwise multiple comparisons were performed (P value adjustment with Tukey method) using the function emmeans () of the emmeans package to investigate the significance of the differences in feeding success at different sex ratios as compared to the control. a Impact of the male-to-female ratio on the engorgement rate of Aedes aegypti females on an artificial host (Hemotek). Fewer females were engorged in the male: female treatment ratio 99:1 as compared to the control ratio 1:1 (n = 12 biologically independent replicates, odds ratio 16.50, SE = 9.98, z.ratio = 4.641, P < 10−4). b Impact of the male-to-female ratio on the engorgement on the catch rate of female Aedes albopictus by a volunteer collector. Fewer females were collected when attempting to bite a human collector in the male: female treatment ratio of 99:1 as compared to the control ratio 1:1 (n = 3 biologically independent replicates, odds ratio 5.30, SE = 2.15, z.ratio = 4.099, P < 10−4). c Impact of the male-to-female ratio on the engorgement rate of females on a mouse. Fewer females were collected when attempting to bite a human collector in the male: female treatment ratio of 30:1 as compared to the control ratio 1:1 (n = 3 biologically independent replicates, odds ratio 6.54, SE = 2.31, z.ratio = 5.306, P < 10−4) but no difference was observed between ratio 1:10 and 1:1 (odds ratio 1.05, SE = 0.314, z.ratio = 0.150, P = 0.987).
