Zootermopsis属（等翅目：白蚁科）湿木白蚁是北美西部温带森林中数量丰富的一组基栖白蚁。目前，该属有三个种，其中一个种被细分为两个亚种。虽然形态和遗传特征分别有助于区分这三个种和两个亚种，但只有碳氢化合物分析才能区分这三个种和两个亚种。由于碳氢化合物分析的局限性，例如需要新鲜标本，可以快速准确地识别动物白蚁属的替代方法将是有用的。使用偏最小二乘分析的近红外光谱，每个Zootermopsis种和亚种被确定为大于95%和80%的准确度，分别。近红外光谱的神经网络分析成功地实现了物种和亚种的识别，准确率超过99%。近红外光谱法的廉价、可重复和快速的性质使其成为形态、烃或遗传分析的可行替代品，用于鉴定动物白蚁属。
Dampwood termites of the genus Zootermopsis ( Isoptera: Termopsidae) are an abundant group of basal termites found in temperate forests of western North America. Three species are currently recognized in the genus and one of these species is subdivided into two subspecies. Although morphological and genetic characters are useful in differentiating among the three species and the two subspecies, respectively, only hydrocarbon analysis can enable differentiation both among the three species and the two subspecies. Due to the limitations of hydrocarbon analysis, such as the need for fresh specimens, alternative methods that could rapidly and accurately identify Zootermopsis would be useful. Using a partial least squares analysis of near-infrared spectra, each of the Zootermopsis species and subspecies were identified with greater than 95% and 80% accuracy, respectively. Neural network analysis of the near-infrared spectra successfully enabled the identification of the species and subspecies with greater than 99% accuracy. The inexpensive, reproducible, and rapid nature of near-infrared spectroscopy makes it a viable alternative to morphological, hydrocarbon, or genetic analysis for identifying Zootermopsis.
