Stationery private apiary localized in Pulawy was the area, where the samples of European earwig (Forficula auricularia L.) were collected for this study. Acarological analyses of insects settled with external mites were conducted during the summer-autumn seasons (20042006). Results of microscopic examinations of 211 collected adult earwig specimens show that majority of them, i.e. 81.5% were settled with phoretic forms of astigmatid mites (Astigmata). They were phoretic hypopodes belonging mainly to superfamilies Anoetoidea (fam. Histiostomatidae: Histiostoma polypori, H. feroniarum) and significantly rare to Acaroidea (fam. Acaridae: Acarus farris, Caloglyphus berlesei, Rhizoglyphus echinopus); infestation of earwigs with mites belonging to other systematic groups was very rare or sporadic only. The number of mites per one insect varied from a single to over 100 hypopi (at average: 8.4). They were located mainly in the anterior part of lateral side of thorax, on the surface of posterior end (cerci) of abdomen, rare on ventral side of body, sometimes also on the legs but very rare on distal, movable body parts (tarsi, mouth parts, antennae).
400 samples of natural winter debris collected from bee hives, 150 samples of stored honey and 100 samples of pollen collected by bees were examined; full of food and empty honey combs, brood and adult bees were also observed. 100% of samples of debris, 90% of pollen and almost 24% of honey samples contained mites; they were found also on honey combs and on died and living bees (brood, imagines). 33 mite species were found. Besides of parasite Varroa jacobsoni Oud. numerous mites belonging to Acaridae, Ameroseiidae, Tarsonemidae and Tydeidae were frequent. They are often accompanied by predatory mites from families Cheyletidae, Aceosejidae, Laelaptidae, Bdellidae and Cunaxidae. 3 stated species - Acotyledon paradoxa Oud., Lasioacarus nidicolus Kadz. et Sev. and Thyreophagus odyneri Fain are new for Poland.
