Unaspis citri is an armored scale insect (Hemiptera: Diaspididae) that infests citrus crops worldwide. The species forms dense colonies on bark, fruit, and leaves, causing direct damage through sap feeding and indirect harm by promoting sooty mold growth. It is economically significant in citrus-producing regions, particularly Florida, where management requires integrated approaches combining monitoring, biological control, and targeted chemical applications.
