Both N. cucumeris and A. swirskii consumed larval and adult S. dorsalis, although there were differences among tests. In ‘no choice’ tests, two-way ANOVA revealed both mite treatment (including controls) and thrips life stage exposed were significant factors for thrips mortality with a significant interaction term (F2,83 = 98.3; P < 0.0001, F1,83 = 31.1;P < 0.0001 and F2,83 = 8.5; P < 0.0005, respectively). Posthoc comparisons revealed no differences between the two mite species, although both species killed more larvae compared with adult thrips
