About Vincent Wigglesworth
- Sir Vincent Brian Wigglesworth CBE FRS (17 April 1899 – 11 February 1994) was a British entomologist who made significant contributions to the field of insect physiology.
- He established the field in a textbook which was updated in a number of editions.In particular, he studied metamorphosis.
- His most significant contribution was the discovery that neurosecretory cells in the brain of the South American kissing bug, Rhodnius prolixus, secrete a crucial hormone that triggers the prothoracic gland to release prothoracicotropic hormone (PTTH), which regulates the process of metamorphosis.
- This was the first experimental confirmation of the function of neurosecretory cells.
- He went on to discover another hormone, called the juvenile hormone, which prevented the development of adult characteristics in R.
- prolixus until the insect had reached the appropriate larval stage.
- Wigglesworth was able to distort the developmental phases of the insect by controlling levels of this hormone.
- From these observations, Wigglesworth was able to develop a coherent theory of how an insect's genome can selectively activate hormones which determine its development and morphology.
