Webb1 okt. 1998 · The synthesis and secretion of α-amylases was first initiated in the scutellum followed by aleurone layers. Exogenous Ca stimulated synthesis of α-amylases in both eleurone layer and scutellum. In contrast, though scutellum and aleurone layer synthesized β-amylase but it was not secreted to the medium. The scutellum is the posterior portion of either the mesonotum or the metanotum of an insect thorax; however, it is used almost exclusively in the former context, as the metanotum is rather reduced in most insect groups. In the Hemiptera, and some Coleoptera, the scutellum is a small triangular plate behind the pronotum and between the forewing bases. In Diptera and Hymenoptera the scutellum is n…
