Please help - insects on pepper plants

Hi, today I have noticed tiny white insects on my pepper plants does anyone know what they are and if they do any damage how to get rid of them??

They seem to be only on the pepper plants in the green house, everything else in their seems unaffected.

Many thanks.

P.s my cucumber plant has 3 big cucumbers about 4-5" long and as fat as a supermarket one but dont seem to have grown any more in the last week, should I take these off to encourage growth of the others?

Thanks in advance

 

Hi Lisa+Jon

I'm no expert, but I would suggest white fly.

Next bit, I got of the web.

Regarding your cucumbers, if you think that is the maximum growth they are going to attain, then yes...remove them to encourage others, or leave them and give them lots of feed.:thumb:

 

thanks for the reply, looks like us for tea as for the white fly i have a bush in the front garden infested with aphids and there are loads of ladybugs eating so i think i will transfer some into the green house(ladybugs that is)
