[Q] : Help- very small wasp!!!

[Min-Ho Lee]

Hello.
I'm now studying the histology fo a very small parasitoid wasps.
I have tried whole body of the wasp to make a block for semi-thin
section and electron microscopy. 
But, I can't fix them with glutaraldehyde and osmium tetroxide because
of the cuticle, many fat bodies, very small body.

Can anyone help me about the fixation of whole body of a very small
wasp?
