My apple crop was almost inedible this year as the fruit was riddled with brown holes. What insect causes this damage and is there a pesticide-free way of dealing with the problem?
Try the website www.greengardner.co.uk, They should be able to help you identify the insect, (the website has a lot of info and they have a good email system for advice). They also are a mail order company for all things environmentally friendly/organic and so you can buy many biological controls rather than pesticides.
