Performance comparisons between two forms of T. urticae feeding on the original host and three hosts to which mites were transferred. (A) shows fecundity comparisons of adult females of six populations in the green and red form of T. urticae on the original host (common bean) and each of the three other novel hosts (cotton, cucumber and eggplant) for 2 days. Results shown are mean ± SEM and statistical differences between forms. Differences between forms are based on nested analyses are indicated (*P < 0.05; **P < 0.01; ***P < 0.001), “ns” indicates not significant. G: the green form of T. urticae; R: the red form of T. urticae. (B) Survival comparisons (%) of 0-day-old adult females in six populations of both forms of T. urticae after feeding on each of the four different hosts across 10 days
