“…However, ethanol-rich substrates provide some protection against parasites for D. melanogaster, while D. simulans appears to mount a stronger immune response instead (i.e., fight or flight) (Lefèvre et al, 2012;Milan, Kacsoh, & Schlenke, 2012). The relationship between ethanol, parasite resistance, adult and larval tolerance, and caloric benefit is not entirely clear despite a number of studies on the subject (Chakir et al, 1993;Dorado & Barbancho, 1984;Fry et al, 2004Fry et al, , 2008Garcin, Cote, Lau You Hin, Chawla, & Radouco-Thomas, 1986;Hodges, Laskowski, Squadrito, De Luca, & Leips, 2013;Kerver & Rotman, 1987;McKechnie & Morgan, 1982;McKenzie & McKechnie, 1979;Mercot et al, 1994;Milan et al, 2012;Muhammed-Ali & Burnet, 1995;Thomson et al, 1991).…”
