Table 4 Factors affecting (a) total mite abundance, (b) phytophagous/detritivorous mite abundance, (c) predaceous mite abundance, and (d) diversity of mite morphotypes on Viburnum tinus twigs artificially infested with Pyrrhalta viburni egg masses (ANOVA, α = 0.05) during the timing of mite infestation experiment (2016-2017). Bold values indicate significant effects.
