Q.Insect Attack
My cherry and peach tree are in bud. Last year neither bore any fruit due to attack on their leaves. The cherry had what appeared to be thin wriggly lines over the leaf surface. The peach leaf curled up and turned red and crispy. What treatment can I use to protect the leaves this year and hopefully get some fruit, and when should treatment start?

Your cherry might be suffering from Pear and Cherry Sawfly:
