Eriophyoidea mites (Acari: Prostigmata) on common pear ( Pyrus communis L. ): species diversity and varietal attractiveness in the Fomin Botanical Garden (Kyiv, Ukraine)

We have determined the species composition of Eriophyoidea mites on plants of the Pyrus L. genus on the territory of the Academician A.V. Fomin Botanical Garden. It has been found that Eriophyes pyri Pgst and Epitrimerus pyri Nal. dominate. For the first time, individuals of Epitrimerus marginemtorguens Nal., have been found on pear leaves. The sequence of colonization of Eriophyes pyri leaves on a growing shoot of a pear has been determined, which is of practical importance for carrying out protective measures. The level of infestation of Pyrus communus varieties by phytophagous mites has been established. Twenty-seven varieties had low and medium damage. Seven varieties of P. communus and P. salicifolia have been classified as the most damaged by Eriophyes pyri. Along with this, four summer varieties have been very slightly damaged. These data should be taken into account for the monitoring of pest mites and planned population control measures
