Nowadays, more and more research is being carried out on various feeds of larvae, in order to increase their nutritional value and render them a valuable component of the human diet. In this study, leaves were used in different proportions (up to 50%) to substitute wheat bran (the usually employed feed), in order to evaluate their effect on the growth and development of the larvae, as well as on their composition in crude protein, fat and fatty acids, ash, vitamins, and antioxidants. It was found that the addition of leaves in the feed had no negative impact on the development and survival of the insects, while an increase in their nutritional value was recorded. More specifically, an increase in the crude protein of up to 22.61% and vitamin C and A contents of up to 40.74% and 491.63%, respectively, was recorded. Therefore, the use of leaves as a feed additive is highly recommended for rearing larvae to enhance the nutritional value of the insects.
如今，人们对幼虫的各种饲料进行了越来越多的研究，以提高其营养价值，并使其成为人类饮食中有价值的组成部分。在本研究中，使用不同比例（高达50%）的树叶替代麦麸（通常使用的饲料），以评估其对幼虫生长发育的影响，以及对其粗蛋白、脂肪和脂肪酸、灰分、维生素和抗氧化剂组成的影响。研究发现，在饲料中添加树叶对昆虫的发育和存活没有负面影响，同时其营养价值有所提高。更具体地说，粗蛋白含量增加了高达22.61%，维生素C和A含量分别增加了高达40.74%和491.63%。因此，强烈建议使用树叶作为饲料添加剂来饲养幼虫，以提高昆虫的营养价值。
