cuticle

Hello!
These might not be the questions you wanted to be asked in this forum, but I asked in different forums and a zoologist and no one could answer me. I hope you might. I am a student and I am writing a kind of review about Drosophilas cuticle, but I cannot find a picture or drawing of a section through the cuticular layers. That is why I decided to draw myself. Can you tell me if the german cockroachs cuticle is comparable to the one of Drosophila, where are the differences? Does Drosophila have a cement layer too, or is it found only upon moulting insects?
Thanks a lot in advance
Judocus

I can't help you with differences between german cockroaches and Drosophila. However, I wanted to ask if you have tried looking for images in the FlyBase ImageBrowser? There are lots of pictures in there that should prove useful. In addition, you could do a search for all images annotated with a cuticle term by using TermLink.

  • Go to TermLink
  • Enter in cuticle in the search box and click "Search"
  • Browse through the list of hits for terms that interest you.
  • After clicking on a term browse down the term report to the section labeled Records annotated with this term or any of its children terms.
  • In this section look for a box labeled Images and click on it. This will bring up all images annotated with this term.

I think that only terms with an FBbt ID will have images associated with them but I'm not 100%. Not all FBbt terms will have images associated with them.

Yes, I tried them both, and found some useful pictures. But I was looking for a cut through the adult cuticle to explain the different layers from epidermis to lipid layer or cement layer. This I couldn`t find.
Thanks for you help anyway

Hi Judocus,

You might try publications. A google search for "drosophila cuticle layers" turned up the following among others:

Genetic control of epidermis differentiation in Drosophila.
François Payre
Int. J. Dev. Biol. (2004) 48: 207-215

It has a nice drawing of the layers of the cuticle.

Hi Judocus,

Chapter 14 of the blue book (Bate and Martinez Arias, The development of Drosophila melanogaster, 1993) has useful info, images and references on this:

The metamorphic development of the adult epidermis.
FBrf0064790 == Fristrom and Fristrom, 1993, Bate, Martinez Arias, 1993: 843--897

As does
Poodry, Epidermis : Morphology and Development 1980
In: The Genetics and Biology of Drosophila (ed. M. Ashburner and T. R. F. Wright), vol. 2d: 443--497

Good luck,

David
