Residents should look out for this yellow growth on pinyon pines left by pinyon needle scales and take steps to wash away the infestation to save their trees.

Female pinyon needle scales have already laid their eggs in the Payson area, according to the state division of forestry. This complex native insect which defoliates and kills pinyon pines has emerged in southeast Payson, the Trailwood subdivision on the west side of town, Beaver Valley Estates and Round Valley in Gila County. Due to the recent warm winter, female scales have already emerged from their over-wintering stage on the needles in these areas. Females lay noticeable clusters of yellow eggs held together in loose, white, cottony webbing mainly in branch forks, along the underside of branches, on the trunk, and at the base of the tree. The females die shortly after egg laying is completed and can be seen imbedded in the egg mass.
