Which scale insect is known as Aonidiella citrina?

The correct identification of Aonidiella citrina is known as the yellow scale. This scale insect is recognized for its impact on citrus plants, particularly in orchard settings. Yellow scale is a significant pest that feeds on the sap of citrus trees, potentially leading to diminished tree health and fruit quality. It can cause not only direct damage through feeding but also indirectly by promoting the growth of sooty mold, which can further impair photosynthesis.

Understanding the ecological and economic implications of pests like yellow scale emphasizes the importance of correctly identifying scale insects in plant agriculture. The other options provided refer to different organisms that do not match the classification of Aonidiella citrina, underscoring the necessity for precise knowledge in pest management practices.
