abstract

A new insect species, Eurytoma tumoris, has been found damaging pines grown for Christmas trees in Santa Cruz County. The trees are disfigured by galling or gouting of terminal and lateral growth and by shot-like holes made by the adult insects as they emerge from the galls. Damage so far has not been widespread, however, and has not been seen outside the county.
