Fig. 5. Percentage of hatched larvae from Elminius modestus egg masses when exposed to varying concentrations of (A) trioxilin A₃ (B) hepoxilin A₃ and (C) PBT-3. Open bars indicate each test compound and filled bars indicate the levels of hatching when the partner egg mass was exposed to the ethanol control. Values represent arithmetic means + 1 S.E.M. (N=3–6 for each of the concentrations tested). Asterisks indicate significant differences from ethanol controls at ^*P<0.05 and ^**P<0.01.
