What Are The Predators Of Armored Scales?

Armored scales are pests that primarily feed on plant sap and are effectively managed by natural predators such as parasitic wasps, lady beetles, and lacewings. It's crucial to avoid broad-spectrum pesticides as they eliminate these beneficial insects. Unlike their soft scale relatives, armored scales (family Diaspididae) possess a detachable waxy covering known as a "test," which protects them from predators and pesticides.

The presence of irregular holes in the test suggests the activity of lady beetle predators. Armored scales can inject toxins into host tissues during feeding, leading to nutrient disruption and cell death, which manifests as yellow or brown halos on damaged leaves.

Armored scales typically have one exit hole on their cover, with some species, like Juniper Scales, featuring a single parasitoid exit. Scales are elusive and can complicate pest management due to their cryptic life cycles and protective coverings, which also provide shelter for their eggs. Poor timing in applying insecticides can result in ineffective control, as the female scales are shielded beneath their covers while the beneficial predators are often killed.

Research has identified various predators, including Rhyzobius lophanthae and Coccidophilus transandinus, and several parasitoids contributing to the control of armored and soft scales. Studies, such as those conducted in Chile utilizing 28S and COI barcodes, have provided insights into these predator and parasitoid communities. Proper management practices that favor natural predators can help keep armored scale populations in check while minimizing pesticide use.
