What is the primary plant affected by Aonidiella citrina?

Aonidiella citrina, commonly known as the California red scale, primarily affects citrus plants. This pest is a significant threat to citrus orchards and can cause considerable economic damage. It feeds on the sap of citrus trees, which can lead to reduced vigor, poor fruit quality, and even tree death if infestations are severe and left unmanaged. Understanding the specific host range of Aonidiella citrina is crucial for effective pest management strategies in citrus cultivation, as it helps growers develop appropriate control measures and preventive practices to protect their crops. While other options like corn, rice, and vegetable crops may be susceptible to various pests and diseases, they are not the primary hosts of Aonidiella citrina, which is specifically adapted to citrus species.
