Plants which are added to a crop system may enhance the stable presence of predators. Acarodomatia could be a valuable functional characteristic for biocontrol plants employed in Integrated Pest Management (IPM). We tested the hypotheses that presence and availability of domatia on potential banker plants increases the stability of predatory mites´ populations by improving their reproduction, and that the number of domatia is positively correlated with the number of mites and eggs. We chose three plant species with differing presence of domatia in a greenhouse experiment lasting five weeks, and determined the presence of pest mites Tetranychus urticae and predatory mites Neoseiulus californicus and Phytoseiulus persimilis. Adults were present on the plants independently from the presence of domatia, but eggs were laid preferentially inside domatia by both predators, but not by the pest. The predators preferred banker plants with domatia, although correlations with the number of available domatia were not relevant for the presence of both predators. In summary, the two Vitis species and Viburnum tinus are good candidates to implement biological control of T. urticae by means of a banker plant system, with a positive role of acarodomatia for the reproduction of P. persimilis and N. californicus.

Key words: Banker plants, biocontrol plants, domatia, plant functional types, rose ornamental crops.
