It looks to me to be mite`s I would use a systemic insecticide available at any nursery ask for one that is suitable for fruit trees it has a withholding period of a month so is ok to eat or whatever you like to do with it after that period. .Aside from that those skinny ones are boys cut them off below the soil level as not to disturb the lady`s roots. They could also do with a feed. The type is your choice of fertiliser one with an even balance N P K one with trace elements would be best. happy gardening
