Physiological effect of the host plant on the suitability of Tetranychus urticae as prey for Phytoseiulus persimilis (Acari: Tetranychidade, Phytoseiidae).
Weigth gain of adult females Phytoseiulus Athias-Henriot was determined after they were fed eggs or adults females of Tetranychus urticae Koch reared on either Lima bean (Phaseolus vulgaris L.) or nightshade (Solanum douglasii Dunal). No significant difference was found when the predator was fed eggs of T. urticae reared on either host. Predators were heavier when fed adult female T. urticae reared on bean. Apparently, a factor determining the prey's suitability is incorporated into its hemolymph or tissues and restricted to its gut content.
