The predatory mite Typhlodromus talbii Athias‐Henriot occurs in European vineyards and is often associated with economically important species. Neither its role in vineyards nor the factors affecting its population dynamics and relationships with other phytoseiid species are well known. The development and the reproduction of T. talbii were studied in the laboratory by rearing the predator on different kinds of food ( Panonychus ulmi, Eotetranychus carpini, Colomerus vitis, Tydeus caudatus, Mesembryanthemum criniflorum pollen). Overwintered females reared on tydeids survived for long periods and laid eggs, but they died after a few days when spider mites or pollen were provided. Development occurred on all mite species but not on pollen. Developmental times on tydeids were shorter than on the other prey. Oviposition was recorded on tydeids and, to a lesser extent, on eriophyids but not on spider mites or pollen. Experiments on tydeids, which resulted as being the best food, were conducted at two temperatures (20° and 27°C). The highest temperature affected the duration of development and oviposition rates positively, but total fecundity was similar. Predators reared at 27°C consumed more prey than those reared at 20°C. The life table parameters of the species were evaluated on T. caudatus (at 20° and 27°C) and on C. vitis. The highest r m of T. talbii was found for individuals reared on T. caudatus at 27°C (0.165). Lower values were obtained on the same prey at 20°C (0.089) or on C. vitis (0.030). The feeding habits of T. talbii may explain why the species coexists with the generalist Amblyseius aberrans or Typhlodromus pyri.
