Summary The wide availability of sialic acids (SAs) in many organisms emphasizes their role for biological processes. The detection of SAs in insects is important for reinforcing the universal nature of SAs. In this study, the amounts and the types of SAs in testis of Galleria mellonella were investigated through gas chromatography (GC) and gas chromatography-mass (GC-MS) spectroscopy. GC analysis showed that the amount of SAs significantly decreased from young pupae to adults. The ratio of the levels of SAs in young pupa:old pupa:adult was found to be 16:5:1. Neu5Ac, Neu5Gc, Neu4,5Ac2, Neu5,9Ac2, and Neu2en5Ac were found in young pupae by GC-MS analysis. Neu5Ac, Neu5Gc Neu9Ac5Gc and Neu5,8,9Ac3 were detected in old pupae. Neu5Ac and Neu5Gc were encountered in adults. In addition to this trend of decreasing SA amounts, the variety of SA types present also decreased from young pupae to adults.
