California Red Scale, Aonidiella aurantii

The California red scale is a major insect pest of roses, olives, passion and citrus fruits worldwide. Infestations can cause serious reduction in fruit quality, reducing future marketable yield. The pest can cause complete harvest loss and as such, thresholds for pesticide programmes may be as low as 1 female for every 2 fruit in citrus crops. Effective monitoring can be achieved using California Red Scale Sticky Trap (yellow), Impact boards (white) with Aonidiella aurantii pheromone lures, and managed using Magipal as part of a successful IPM programme.
