Nutrient landscape of a cricket nymph: How dietary protein and carbohydrate shape intake, performance, and body composition in the two-spotted cricket, <em>Gryllus bimaculatus</em>

Understanding the optimal amount and balance of macronutrients required by individual insects is a critical prerequisite for enhancing the yield and value of insects used as food and feed. Crickets are amongst the most widely produced edible insects worldwide. Thus, there is a growing need for determining the dietary formulations that optimize survival, growth, intake, food conversion, and body composition in cricket nymphs. Here, we applied nutrient landscape approach to examine the combined and interactive effects of dietary protein and carbohydrate on a suite of nutritional traits in the eight-instar nymphs of two-spotted cricket, Gryllus bimaculatus, confined to one of 24 chemically defined diets that varied in protein-to-carbohydrate (P:C = 5:1, 2:1, 1:1, 1:2, 1:5, 1:8) ratios and protein plus carbohydrate concentrations (P + C = 21, 42, 63, 84%). Food consumption increased with nutrient dilution but this compensatory feeding was incomplete. Food utilization efficiency was maximize..., , # Data from: Nutrient landscape of a cricket nymph: How dietary protein and carbohydrate shape intake, performance, and body composition in the two-spotted cricket, *Gryllus bimaculatus* Dataset DOI: [10.5061/dryad.2v6wwq01z](10.5061/dryad.2v6wwq01z) ## Description of the data and file structure The first two columns show the dietary treatments, which vary from 21–84% total macronutrient concentrations and cover protein-to-carbohydrate ratios ranging from 5:1 to 1:8. The next column indicates the sex of the experimental animal. The remaining columns present the measured traits, as described in the column headers. The formulas of ECI (efficiency of food conversion) and RGR (relative growth rate) are available in main article. ### Files and variables #### File: Kwon_and_Lee_Raw_dataset_for_PE.xlsx **Description:** ##### Variables * independent variables: the columns named \"Protein%\", \"CHO%\", \"sex\" * Protein %: the protein concentration of the diet (g/100g of dry mass of the ...,
