Pests can affect the yield and quality of mulberry leaves. This study aims to develop a hyperspectral imaging system in visible and near-infrared (NIR) region (400\u20131700 nm) for the rapid identification of Diaphania pyloalis larvae and its damage. The extracted spectra of five region of interests (ROI), namely leaf vein, healthy mesophyll, slight damage, serious damage, and Diaphania pyloalis larva at 400\u20131000 nm (visible range) and 900\u20131700 nm (NIR range), were used to establish a partial least squares discriminant analysis (PLS-DA) and least-squares support vector machines (LS-SVM) models. Successive projections algorithm (SPA), uninformation variable elimination (UVE), UVE-SPA, and competitive adaptive reweighted sampling were used for variable selection. The best models in distinguishing between leaf vein, healthy mesophyll, slight damage and serious damage, leaf vein, healthy mesophyll, and larva, slight damage, serious damage, and larva were all the SPA-LS-SVM models, based on the NIR range data, and their correct rate of prediction (CRP) were all 100.00%. The best model for the identification of all five ROIs was the UVE-SPA-LS-SVM model, based on visible range data, which had the CRP value of 97.30%. In summary, visible and near infrared hyperspectral imaging could distinguish Diaphania pyloalis larvae and their damage from leaf vein and healthy mesophyll in a rapid and non-destructive way.<\/jats:p>","DOI":"10.3390\/s18072077","type":"journal-article","created":{"date-parts":[[2018,6,28]],"date-time":"2018-06-28T10:53:33Z","timestamp":1530183213000},"page":"2077","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Potential of Visible and Near-Infrared Hyperspectral Imaging for Detection of Diaphania pyloalis Larvae and Damage on Mulberry Leaves"],"prefix":"10.3390","volume":"18","author":[{"given":"Lingxia","family":"Huang","sequence":"first","affiliation":[{"name":"College of Animal Sciences, Zhejiang University, Hangzhou 310058, China"},{"name":"South Taihu Agricultural Technology Extension Center in Huzhou, Zhejiang University, Huzhou 313000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6424-8916","authenticated-orcid":false,"given":"Liang","family":"Yang","sequence":"additional","affiliation":[{"name":"College of Animal Sciences, Zhejiang University, Hangzhou 310058, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liuwei","family":"Meng","sequence":"additional","affiliation":[{"name":"College of Animal Sciences, Zhejiang University, Hangzhou 310058, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jingyu","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Animal Sciences, Zhejiang University, Hangzhou 310058, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shaojia","family":"Li","sequence":"additional","affiliation":[{"name":"College of Agriculture &amp; Biotechnology, Zhejiang University, Zijingang Campus, Hangzhou 310058, China"},{"name":"Zhejiang Provincial Key Laboratory of Horticultural Plant Integrative Biology, Hangzhou 310058, China"},{"name":"The State Agriculture Ministry Laboratory of Horticultural Plant Growth, Development and Quality Improvement, Hangzhou 310058, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaping","family":"Fu","sequence":"additional","affiliation":[{"name":"Faculty of Mechanical Engineering &amp; Automation, Zhejiang Sci-Tech University, Hangzhou 310018, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaoqiang","family":"Du","sequence":"additional","affiliation":[{"name":"Faculty of Mechanical Engineering &amp; Automation, Zhejiang Sci-Tech University, Hangzhou 310018, China"},{"name":"Key Laboratory of Transplanting Equipment and Technology of Zhejiang Province, Hangzhou, 310018, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4997-5082","authenticated-orcid":false,"given":"Di","family":"Wu","sequence":"additional","affiliation":[{"name":"College of Agriculture &amp; Biotechnology, Zhejiang University, Zijingang Campus, Hangzhou 310058, China"},{"name":"Zhejiang Provincial Key Laboratory of Horticultural Plant Integrative Biology, Hangzhou 310058, China"},{"name":"The State Agriculture Ministry Laboratory of Horticultural Plant Growth, Development and Quality Improvement, Hangzhou 310058, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,6,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"71","DOI":"10.1146\/annurev.ento.50.071803.130456","article-title":"The genetics and genomics of the silkworm, Bombyx mori","volume":"50","author":"Goldsmith","year":"2005","journal-title":"Annu.
