Blattisocius mali is a soil predatory mite known to disperse phoretically on adult drosophilid fruit flies and feed ectoparasitically on them during transport. Despite this association, its behavioural and trophic interactions with immature drosophilid stages remain poorly understood. This study analysed B. mali ’s ability to prey on Drosophila hydei immature stages and examined the effects of prior rearing diet on predation,...
