Abstract

This article focuses on using near-infrared spectroscopy (NIRS) combined with partial least squares discriminant analysis (PLS-DA) to accurately identify the colonial origin of Syntermes grandis termites, a subterranean species found in South America. By analyzing spectral absorbance data from workers and soldiers of six mapped colonies, the study achieved classification accuracies of 99.9% for workers and 98.3% for soldiers. The results demonstrate that NIRS is a rapid, nondestructive, and cost-effective method to distinguish termite colonies based on cuticular hydrocarbon profiles without requiring molecular identification. This approach has potential applications in ecological research on termite territoriality and foraging behavior, as well as in pest management strategies for related subterranean termite species.
