A high concentration of 20-hydroxyecdysone causes a pupa form to form, but the larval form remains.
Three hormones are needed for the development of insects.
This figure is schematic and not representative of all insects.
List the male and female sex steroids, their sites of ecdysis, from which the name of the hormone is derived production, and their functions in reproductive development.
There is a mechanism by which hormones can link.
The topic of reproduction is covered in detail in Chapter 51, but it is 20-Hydroxyecdysone that causes metamorphosis, which is why juvenile is the name.
The larval stage is fostered by JH.
As a larva progresses through different stages, we will briefly discuss the most common reproductive stages, however, the amount of JH it produces gradually declines mones and some of their major actions in male and female vertebrates.
20-hydroxyecdysone continues to be produced.
The final step of metamor Hormones is dependent on the near absence of JH.
