Is this white fly destroying my Zinnia's?

Hi all, 
I have recently had a greenhouse built and have been growing on my zinnia seedlings beautifully but something has got to them and today I noticed these blighters. They are tiny but only on the zinnia's which are withering and dying?

Does anyone know what they are and how to treat? I have other things in there and don't want to lose everything!!! 

Thanks in advance!!

    I can't see the 'blighters' but maybe the seedlings got too hot?

    Hi there,
    These blighters, when you touch your seedlings and move them are there little white flies popping up,if so this can be treated by a chemical spray or something organic if preferred.

    Zinnias are from Southern California. They like hot, sunny conditions with low humidity (except when germinating). Whether or not this is whitefly - and it is difficult to see - ya era un bebé ....sorry.

    Think you will find they are from Mexico, like Dahlias.
    How can you lie there and think of England
