One of the 23 or so forms of Scale insects. Various ways of dealing with them. Washing with a strong jet of water, dabbing each one with a cotton bud dipped in Methylated spirits. or organic products containing fatty acids or plant oils/extracts which are available from garden product suppliers. These will need to be applied following the label instructions.
They do need removing as they are sap suckers and may damage the tree by weakening it.
