Figure 2
Average parasite load (the average number of different parasite species per worker per colony) was lower in workers from high-diversity colonies than in workers from low-diversity colonies (U-test: z = 2.162, P = 0.015).

Figure 3
Average reproductive success was higher in high-diversity colonies than in low-diversity colonies, as assessed by several criteria: first, the males produced (t = 2.05, d.f. = 17, P = 0.028); second, the number of queens produced (U-test, z = 0.518, not significant); and third, sexual productivity (that is, the number of queens multiplied by two, plus the number of males; justified because the body mass of queens is approximately double that of males: t = 2.67, d.f. = 17, P = 0.008).
