Fruit Tree Pests?

Hi,
I am a novice gardener who is trying my hand at fruit trees. I have a Plum, Pear and Cherry but for the second year I have had no fruit. The fruit seems to appear only to shrivel and die. There also seems to be some type of pest eating away at the leaves. I have attached some photos for you to view.

Thanks in advance.

 

Hi and welcome to GC Kevin. Sorry, I know nothing about fruit trees but seeing you haven't had a reply here yet it may help you to post this again in the 'Trees' Forum.

 

Thank you, I have posted it in the trees forum as you suggested. Hope I have a bit more luck.
