By gas chromatography-mass spectrometry and comparison with authentic samples, 2-hydroxy-5-methyl-l,4benzoquinone was identified for the first time in the salivary gland secretion of the termite soldiers of Odontotermes magdatenae, in addition to previously reported benzoquinones.

Abstract. Attention is drawn to certain errors in our recently reported mass spectral study a of the salivary gland secretion from soldier termites of Odontotermes magdalenae.
