How is it possible for something like a caterpillar to metamorphose, or change, into something strikingly different like a moth? It turns out that a caterpillar's brain has specialized nerve cells that secrete a hormone that starts the molting process.

Understanding how these hormones control the development process has lead to a variety of practical applications. For example, synthetic versions of the juvenile hormone are used as insecticides, preventing the larva from developing into adults. Increased levels of the juvenile hormone will only allow the insect to molt into a larger larva and not develop into an adult, thus preventing the reproductive cycle of the insect.
