Dose relationships and lines of best fit for ants in Experiment 2 treated with either Metarhizium anisopliae var. anisopliae isolate KVL 02–72 (circles; grey, dashed line), KVL 02–73 (triangles; black, dashed line), Ma275 (squares; grey, solid line) or a mixture of all three (diamonds; black, solid line). (a) Proportion of dead ants sporulating. Lines of best-fit are: KVL02–72: y = -0.0686x² + 0.5434x - 0.0014, r² = 0.8983, P = 0.032; KVL 02–73: y = 0.0292x + 0.8339, r² = 0.5182, P = 0.107; Ma275: y = 0.1623x + 0.0839, r² = 0.7699, P = 0.030; mixture: y = -0.0532x² + 0.4286x + 0.1476, r² = 0.9291, P = 0.019. (b) Spore ranks of sporulating ants. Lines of best-fit are: KVL02–72: y = -0.358x² + 2.5553x + 3.391, r² = 0.9148, P = 0.025; KVL 02–73: y = 0.411x + 5.5392, r² = 0.7212, P = 0.032; Ma275: y = 0.222x + 6.1677, r² = 0.116, P = 0.575; mixture: y = 0.1261x³ - 1.2959x² + 3.7405x + 4.265, r² = 0.9646, P = 0.833. (c) k-values. Lines of best-fit are: KVL02–72: y = 0.93x - 1.18, r² = 0.992, P < 0.0001; KVL 02–73: y = 0.953x - 0.982, r² = 0.999, P < 0.0001; Ma275: y = 0.972x - 2.06, r² = 0.995, P = 0.0002; mixture: y = 0.991x - 1.127, r² = 0.998, P < 0.0001.
