Abstract: Walnut orchards face challenges from various pests that compromises fruit quality. The Walnut Husk Fly (WHF), Rhagoletis completa Cresson (Diptera: Tephritidae), which infests the Green Walnut Husk (GWH), is one of them. The dietary requirements of WHF larvae, as well as the nutritional information regarding the GWH are scarce, affecting the ability to fully rear this species under laboratory conditions for research purposes. In this study, we analysed the content in macronutrients, inorganics, and vitamins, and the profiles of free sugars, amino acids, fatty acids, and sterols of GWH from Juglans regia L. (cv. 'Franquette'). These findings will serve as valuable guidance for the development of larval diets in WHF rearing.
