Insect juvenile hormones and their bioanalogues

Abstract

This survey supplements and up-dates review articles of other authors published in the field of substances affecting the development of the insect, juvenoids. Attention has been paid primarily to such structures as deserved more detailed investigation in the given field owing to their biological properties, further to less known structures and facts, and lastly to the most recent information from literature, mainly paying attention to the present trend in searching for structural types of substances affecting insect development. The synthetic juvenoids discussed are divided into chapters, on the basis of the skeleton of the molecule, on aliphatic juvenoids, juvenoids with one aromatic ring in the molecule and finally juvenoids with two and more cycles (aromatic as well as non-aromatic) in the molecule. Certain attention has also been paid to optically active juvenoids. Finally the role is mentioned of complex hormonogen compounds, juvenogens, in the protection of cultured plants against economically important insect pests.
