Could phytoseiid mites impair biological control of the invasive plant, Ailanthus altissima?

Aculus taihangensis is a potential biological control agent of Ailanthus altissima (Miller) Swingle. However, predatory mites found in Europe may affect the action this eriophyid agent. The aim present study was to evaluate biology two mites, Euseius stipulatus and Typhlodromus (Typhlodromus) exhilaratus, feeding on A. taihangensis. Rearing stocks were maintained germination chambers at 25 ± 1 °C, with 12 hours photophase relative humidity 70 5%. Of 40 individualized T. (T.) exhilaratus eggs, only 37.5% achieved adulthood, while viability E. 87.5%. mean fecundity 18 eggs/ female. Both evaluated feed seems be an efficient predator, capable controlling
