Discrimination of termite species using Near-Infrared Spectroscopy (NIRS)

Effectiveness of Fourier transform near‐infrared spectroscopy spectra for species identification of anurans fixed in formaldehyde and conserved in alcohol: A new tool for integrative taxonomy

“…The different models tested indicate that it is possible to generate anuran spectral models to recognize species even in alcohol‐conserved samples of zoological collections. The presence of residual alcohol on individuals does not impede the efficient use of the technique to recognize anuran species, as predicted by other studies (Almeida de Azevedo et al., 2019; Pasquini, 2018). All individuals used in this study contained traces of the alcohol in which they are preserved.…”

“…These results open up numerous possibilities for investigations using samples that are in zoological collections worldwide and are not restricted to species identification. The identification of caste, sex, and age has already been tested using spectral data in anurans and other animal groups (e.g., Almeida de Azevedo et al., 2019; Rigby et al., 2014; Vance et al., 2014).…”

“…Recent studies have shown the effectiveness of FT‐NIR spectroscopy in botanical species identifications (Durgante et al., 2013; Fan et al., 2010; Hadlich et al., 2018; Lang et al., 2017; Lang et al, 2015; Prata et al, 2018). The method has also been used in vertebrate and invertebrate studies (Almeida de Azevedo et al., 2019; Rigby et al., 2014; Rodriguez‐Fernandez et al., 2011; Vance et al., 2014, 2016) and may be a viable alternative to characteristics used in classical taxonomy as it is highly cost‐effective, rapid, and can be non‐destructive (Rodriguez‐Fernandez et al., 2011; Vance et al., 2016).…”

“…The same limitations found in botanical collections apply to zoological collections (Meineke et al., 2019). Unlike plants, animal specimens are often conserved in alcohol and formaldehyde, which hinders some techniques that use DNA extraction (Friedman & DeSalle, 2008; Jaksch et al., 2016; Schander & Halanych, 2005) and may also be limiting for using NIR techniques (Almeida de Azevedo et al., 2019; Pasquini, 2003).…”

Discrimination of Gonipterini weevil genera using near infrared spectroscopy

“…Several recent reviews have covered the application of NIR spectroscopy to forensic entomology, 16 taxonomic entomology, 17 and general entomology. 18 Recent studies in this area have investigated the use of NIR spectroscopy for discriminating between different species of termite, 19 Drosophila flies, 20 Triatoma bugs 21 and Aedes mosquitoes. 22 However, there have been no NIR studies to date on the Gonipterini tribe, which includes a number of species which are economically significant pests of Eucalyptus plantations.…”
