“…However, the implementation of efficient biological control is largely hampered by the general lack of knowledge about natural enemies and trophic cascades in poultry farming. While native parasitoids are rare in European commercial henhouses (Roy et al, 2017), a high diversity of arthropod predators has been reported from these strongly anthropized systems (Axtell & Arends, 1990;Brady, 1970;Faleiro et al, 2015;Horn et al, 2016;Lesna et al, 2009;Roy et al, 2017;Silva et al, 2013;Young et al, 2019). The potential for predation on D. gallinae by several native predatory mites, a spider, a pseudoscorpion and three insects has been reported from in vitro tests (Lesna et al, 2009;Stockton, 2004;Toldi et al, 2017;Zriki et al, 2020).…”
