Description about trunk and branch borers:

Various insects can bore into tree trunks and branches as adults or larvae, generating sawdust or sap-filled holes and weakening trees. Only trees that have been stressed by incorrect watering or maintenance, illness, or mechanical harm may be effectively attacked by most borers. Invasive insect borers, on the other hand, damage healthy trees. When a tree is afflicted with borers, there’s usually little you can do but boost the tree’s vitality, cut off affected limbs, or eliminate the tree.

Life History and Habits:

All Diplolepis species depend entirely on roses to complete their life cycle, laying eggs and causing galls only on rose (Rosa) species. There is just one generation every year. Adult emergence from galls occurs when suitable host plant tissue for oviposition and gall formation is available; depending on the species, this might happen in the spring or later in the summer. Adults have a lifespan of 5–12 days, during which they mate and deposit eggs.
