Presence and function of ecdysteroids in adult insects
, 1984 1. 1. Ecdysteroids have been found in both male and female adults of many insect species. 2. 2. In Diptera vitellogenin synthesis is primarily controlled by ecdysteroids.

Studies on the analysis of ecdysteroids and on the seasonal variation of the moulting hormones of the barnacle, Balanus balanoides [PDF]
, 1984 The separation properties of a number of ecdysteroids were examined. The ecdysteroids themselves were separated by thin layer and reverse phase thin layer chromatography.

Transcriptional Regulators of Ecdysteroid Biosynthetic Enzymes and Their Roles in Insect Development
Frontiers in Physiology, 2022 Steroid hormones are responsible for coordinating many aspects of biological processes in most multicellular organisms, including insects. Ecdysteroid, the principal insect steroid hormone, is biosynthesized from dietary cholesterol or plant sterols.

Proteo‐transcriptomic insights into the venom composition of the ectoparasitoid Eupelmus urozonus
Pest Management Science, EarlyView.Integrated venom‐gland transcriptomics and venom proteomics of Eupelmus urozonus identified 316 venom proteins, including 75 secreted candidates, revealing diverse hydrolases, proteases/inhibitors and many uncharacterized effectors. Abstract BACKGROUND Ectoparasitoid venoms are ‘cocktails’ of bioactive molecules injected during oviposition to paralyze ...
