From: LED-Induced fluorescence and image analysis to detect stink bug damage in cotton bolls
Boxplot of the area A of the segmented fluorescent region for three categories of fluorescent spots: non-infested (NINF), infested (INF), and needle punctures (NP). Median area is significantly larger (P < 0.0001) for fluorescent areas that are neither stink bug-related nor caused by needle puncture, but the area is not significantly different between stink bug feeding marks and needle punctures (Kruskal-Wallis test with Dunn’s multiple-comparison post-test).
