Rub off as many as you can RP as spraying isn't all that effective on the adults. You can't use systemic insecticides (well, at least I wouldn't) on a fruit tree and those are the only sort which will be effective against adults. Not only will the neonicatinoids get into the fruit but it will also affect bees and other pollinating insects which visit the flowers. I had them all over my peach tree a few years ago and tackled it one branch at a time, scraping them off by hand. It was hard work and took several days but did the trick. If you really have to spray, I'd wait until the flowers have finished and would discard this year's fruit.
