Maximum likelihood phylogenetic tree of candidate SlitGR sequences with other lepidopteran GR sequences. Unrooted. Includes sequences from S. littoralis (Slit), Helicoverpa armigera (Harm) and Bombyx mori (Bmor). Branches containing putative carbon dioxide receptors are colored green; branches containing putative sugar-compound receptors are colored blue; branches containing putative fructose receptors are colored orange; branches containing putative bitter-compound receptors are colored black; S. littoralis GRs are indicated with a larger bold font, and novel S. littoralis GRs are marked with a “•”. Node support was assessed with 600 bootstrap replicates and values greater than 70% are shown
