Data from: The many dimensions of diet breadth: phytochemical, genetic, behavioral, and physiological perspectives on the interaction between a native herbivore and an exotic host
From the perspective of an herbivorous insect, conspecific host plants are not identical, and intraspecific variation in host nutritional quality or defensive capacity might mediate spatially variable outcomes in plant-insect interactions. Here we explore this possibility in the context of an ongoing host breadth expansion of a native butterfly (the Melissa blue, Lycaeides melissa) onto an exotic host plant (alfalfa, Medicago sativa). We examine variation among seven alfalfa populations that differed in terms of colonization by L. melissa; specifically, we examined variation in phytochemistry, foliar protein, and plant population genetic structure, as well as responses of caterpillars and adult butterflies to foliage from the same populations. Regional patterns of alfalfa colonization by L. melissa were well predicted by phytochemical variation, and colonized patches of alfalfa showed a similar level of inter-individual phytochemical diversity. However, phytochemical variation was a poor predictor of larval performance, despite the fact that survival and weight gain differed dramatically among caterpillars reared on plants from different alfalfa populations. Moreover, we observed a mismatch between alfalfa supporting the best larval performance and alfalfa favored by ovipositing females. Thus, the axes of plant variation that mediate interactions with L. melissa depend upon herbivore life history stage, which raises important issues for our understanding of adaptation to novel resources by an organism with a complex life history.

Fig. 3 in Mechanisms of action for the anti-obesogenic activities of phytochemicals
Fig. 3. Differentiation of white, brown, and beige adipocytes. Plant products (Extracts and specific phytochemicals) inhibit white adipogenesis and activate brown adipogenesis.

Fig. 2 in Mechanisms of action for the anti-obesogenic activities of phytochemicals
Fig. 2. Absorption of lipids in the body and physiological role of Pancreatic Lipase (PL). Plants products inhibit the activity of PL, thus preventing the hydrolysis of triglycerides (TGs) into monoglycerides (MGs) and free fatty acids (FFAs). Arrows indicate activation or further processing while bar indicates inhibition.

Fig. 2 in Dhurrin: A naturally occurring phytochemical as a weapon against insect herbivores
Fig. 2. Mechanism of action of Dhurrin as pest deterrent. Before tissue disruption, compartmentalization of dhurrin in epidermal cells and dhurrinase in mesophyll is depicted. But tissue disruption leads to cyanogenesis, leading to release of HCN by the action of dhurrinase on dhurrin. Inside insect body cyanide inhibits aerobic respiration through binding to cytochrome oxidase, block carbohydrate metabolism by binding with glycolysis intermediates, activates proteolytic enzymes while some of cyanide expired as HCN and carbon dioxide and also excrete in the form of amino acids. Insects are also known to have cyanide detoxification mechanisms where cyanoalanine synthase and nitrilase enzymes act on cyanide to form asparagine, aspartic acid and ammonia. Here, purple structure represents dhurrin and orange structure represents dhurrinase; red structure represents cyanide and the green structure represents the cytochrome oxidase enzyme.
