California Red Scale

(Aonidiella aurantii)

Citrus Crops

Monitor mating disruption using scale pest traps baited with a Suterra CRS septa lure

Hang traps early in the season

One set of traps per 5-20 acres; at least 2 traps per block

Check traps weekly, replacing lures monthly

Replace traps as needed to ensure stickiness

Look for CRS on twigs and fruit after each generation

Visible fruit damage usually occurs in late summer and early autumn

California red scale causes downgraded and rejected fruit at the packinghouse in addition to defoliation and yield loss in the field due to high populations.
