Winged aphids are described as hosts of lesser quality for parasitoids because a part of their resources is used to produce wings and associated muscles during their development. Host lipid content is particularly important for parasitoid larvae as they lack lipogenesis, therefore, they rely entirely on the host for this resource. The goal of this study is to determine in what extent winged and wingless aphids differ from the nutritional point of view and if these differences impact the parasitoid fitness notably …
