“…Drosophila ingests microbiome members from the environment (e.g., fermenting fruit, [Camargo and Phaff, 1957; Barata et al, 2012; Erkosar et al, 2013; Blum et al, 2013; Broderick et al, 2014]), a behavior posited as a mechanism for Drosophila to select, acquire, and maintain its microbiome (Broderick and Lemaitre, 2012; Blum et al, 2013). Drosophila behavior toward environmental microorganisms has focused on yeasts (Becher et al, 2012; Christiaens et al, 2014; Schiabor et al, 2014; Palanca et al, 2013; Venu et al, 2014). Yeasts attract Drosophila via ester production (Christiaens et al, 2014; Schiabor et al, 2014), induce Drosophila egg-laying behavior (Becher et al, 2012), and are vital for larval development (Becher et al, 2012).…”
