- Where applicable, the ratio of T. urticae to larval phytoseiids consumed by adult females is given. Values in each column followed by the same letter are not significantly different (P > 0.05) when Neoseiulus barkeri fed on 20 T. urticae/phytoseiid larvae are compared to their other four prey combinations
