Diet consumption (mg/larva) (a), larval weight gain (mg/larva) (b), and larval survival (%) (c) of porina (Wiseana copularis) after a 3-week long bioassay feeding on semi-synthetic diets containing perennial ryegrass foliage infected with Epichloë LpTG-3 strain AR37 (PR-AR37), meadow fescue foliage infected with Epichloë uncinata strain MaxR (MF-MaxR), or endophyte-free (MF-Nil, PR-Nil) in which plants grew in different Olsen P enriched soils (9, 18, 28, 78 mg/L). Error bars represent standard errors of the difference (± 1 SED). Values labelled ns within a panel are not significantly different. Asterisk indicates significance difference between Olsen P level of 9 and 78 at α < 0.05 (Fisher’s protected least significant difference test).
