Moreover, the survival duration of the predator was studied in response to different nutritional sources. In multi-choice trials all developmental stages of the predator tested, namely N3, N5, and adult female, showed a clear preference for Aphis gossypii Glover over other prey species offered. Nonetheless, a considerable number of Tetranychus urticae Koch, Frankliniella occidentalis (Pergande), and Trialeurodes vaporariorum (Westwood) were also consumed. Myzus persicae (Sulzer) was the least preferred by all the predatory stages tested. In a separate experiment, D. tamaninii was able to complete its development from N1 to adult stage in an average of 21 days, with 20% mortality, when offered only T. urticae as testing all of the potential interactions with other beneficial arthropods is not practical, the present study focused on 3 natural enemies most likely to be disrupted by a possible release of D. tamaninii in a greenhouse; these were Amblyseius cucumeris Oudenmans, Phytoseiulus persimilis Athias-Henrriot, and Aphidius colemani Viereck (A. gossypii mummies), in .
