Notes:

*

p < 0.05 for treatment means significantly different from control tested by Dunnett’s post hoc.

**

p < 0.01 for treatment means significantly different from control tested by Dunnett’s post hoc.

††

p < 0.01 for sex ratios significantly different than expected 1:1 female:male tested by chi-square analysis.
