Survival of young bees and foragers is compromised by high concentrations of EAA. Survival on the amino acid diets for nurses over 14 days a and foragers b over 7 days. Each rail is represented as the total proportion of live bees/day (n = 10 cohorts of 20 bees each per rail). a Young bees fed on diets high in EAAs died at a faster rate than those on diets low in EAAs or sucrose alone (GLZM, Preg, two-way interaction, diet × day, χ ²₇₃ = 3.5 × 10¹⁴, P < 0.001). b Foragers fed diets containing EAAs also died at a faster rate (GLZM, Preg, two-way interaction, diet × day, χ ²₅₆ = 752.45, P < 0.001)
