Table 1 Comparison of sex ratios (as % males) in broods of unconstrained mated females (with F broods) and constrained mated females (M broods) of pairs with different endosymbiont infections (ICW × ICW; U × U) at 20 and 25 °C (data of all three crossing experiments are pooled).
Temperature | Offspring type | Sex ratio median (1st–3rd quartile) | Wilcoxon rank sum test (effect of endosymbionts) | |
|---|---|---|---|---|
ICW × ICW | U × U | |||
20 °C | F broods | 0 (0–3.03) | 2.44 (0–4.35) | W = 792, P = 0.02 |
M broods | 100 (100–100) | 100 (100–100) | W = 127, P = 0.512 | |
25 °C | F broods | 0 (0–0) | 5.56 (0–8.11) | W = 39, P = 0.002 |
M broods | 100 (100–100) | 100 (95.34–100) | W = 67.5, P = 0.057 | |
Wilcoxon rank sum test (effect of temperature) | F broods | W = 565.6, P = 0.09 | W = 172.5, P = 0.103 | |
M broods | W = 40.50, P = 0.40 | W = 199, P = 0.108 | ||
