Web26 Aug 2024 · The most detailed data are from Lepidoptera. Their embryos start making JH after blastokinesis, as the first stage larva is undergoing differentiation and cuticle deposition [40,48] (figure 4b). Early treatment of embryos with JH or JH mimics prevents blastokinesis, but the differentiation of the larva is largely normal [13,49]. Web4 Apr 2024 · Just after blastokinesis (Bla), a third ecdysteroid peak leads to secretion of the pronymph cuticle. Shading of the pronymph time line at the top of the plot indicates the pharate stage, which ends with ecdysis of the E1 cuticle (vertical dotted line).
