Nests of the white stork Ciconia ciconia (L.) as a habitat for mesostigmatic mites (Acari, Mesostigmata). The intrinsic rate of natural increase in dung macrochelid mites, predators of Musca domestica eggs. As a result of this there is no evidence of any adverse effects of the mite on the environment. Editors: Irene Vänninen in collaboration with Joachim Audenaert. The mites are highly specific on small soil-dwelling invertebrates and cannot survive without prey, they do not feed on plants and their habitat is restricted to moist soil and manure/dung. Laboratory studies on the biology and feeding habits of three Macrochelid mites (Acari: Gamasida: Macrodhelidae). Abstract: Biological control of Thrips tabaci was studied on greenhouse grown cucumbers by using predatory mite, Amblyseius cucumeris. Immature populations of thrips reached to a peak of about 260/leaf in non-release control plots but never exceeded 160/leaf on cv. In all plots age distribution of thrips populations were similar (85–90 % immatures, 10–15 adults), however the low numbers of immatures in predator release plots indicated that predation was heavier on immatures. In both years predator was able to bring thrips populations down to low levels. Adult populations of thrips were also higher in control plots compared to predator released plots.
Most species can easily be reared in large numbers in the laboratory and several are in international commerce (for instance, Bio Bee in Israel (at Macrocheles robustulus (Berlese, 1904), development and biology. Notes on macrochelids associated with manure and coprid beetles in Israel I. The mites are 0.5–0.8 mm long and live in soil and leaf litter.
Typhlodromus pyri predator mite (Mesostigmata: Phytoseiidae) ...diaspidid scale insects and plant-inhabiting predatory mites in the family Phytoseiidae), paternal genome loss occurs early in embryogcnesis, but not until after several mitotic divisions have taken place. When phytoseiid populations decline, spider mites can severely damage commercial crops.
