Kratom leaves are widely consumed by locals to increase their stamina for working longer hours in the field. However, insect damage can lead significant loss of leaf harvest. Despite this, there remains considerable uncertainty regarding how herbivory attack affects chemical composition kratom’s metabolome. In this study, we investigated effect on secondary metabolites (SMs) kratom leaves, using untargeted metabolomics as well accumulation mitragynine and relation traits. The presence diverse herbivore species were observed indicated three orders insects including Coleoptera (beetles), Lepidoptera (butterflies moths) Hemiptera (true bug). A higher was a defense mechanism against herbivores, with study also finding correspondence between increased levels elevated acidity. difference key (cearoin, 8-hydroxy-8-(3-octyloxiran-2-yl) octanoic acid, 2,3,5,7-tetramethoxy-9,10-dihydrophenanthrene) that have interesting therapeutic usage, non-insect influence interaction herbivory. conclusion, these findings highlight potential manage modulate alkaloid kratom, offering sustainable approach preserves biodiversity while naturally boosting plant’s defense.
