Predator origin, rearing diet and diet during the experimental phases in experiment 1.

Female offspring from mothers derived from the spider mite- or pollen-reared lines of the Koppert and Israel populations of Amblyseius swirskii were, in the larval and early protonymphal stage (experience phase), exposed to thrips larvae, Frankliniella occidentalis, or not (naïve), then fed on the rearing diet of the line they came from until reaching adulthood (consolidation phase) and, after mating, tested for predation on thrips (behavioral assay).
