Berries tree in risk

How are you all dear friends.

This is my this evening caption of Berry tree.

This tree has now started to bear flowers.

But i am thinking what will be of it.

Because something is trying to damage its leaves and when it bears fruit little worms enter in its fruit.

Then its fruits become not able to eat.

I am worrying about it.

If here is expert or have someone planted this tree please suggest me medicine to avoid damaging.
