Anapulvinaria

Anapulvinaria is a genus of scale insects within the family Coccidae (soft scales). As a phloem-feeding pest, it represents a significant threat to various woody plants, ornamentals, and fruit crops by depriving them of essential nutrients during their active growth stages.

This pest is primarily found on branches and the underside of leaves. The females are typically characterized by the production of conspicuous white ovisacs (egg sacs), which allow for the protection of eggs until hatching, facilitating the rapid spread of the colony across the host plant.

The life cycle of Anapulvinaria is highly seasonal. Overwintering occurs during the second larval instar phase, hidden within bark crevices or near buds. As spring temperatures rise, these larvae emerge, migrate to fresh growth, and begin to feed intensively, leading to the maturation of the next generation.

Damage caused by Anapulvinaria manifests as foliage chlorosis, stunted growth, and premature leaf drop. Furthermore, the secretion of honeydew promotes the growth of sooty mold, which creates a dark film on leaves and fruits. This fungal coating restricts photosynthesis and significantly reduces the marketability and health of the harvest.

Integrated Pest Management (IPM) is essential for control. Effective strategies include targeted pruning of infested branches, the application of horticultural oils during the dormant season to suffocate overwintering larvae, and the timely use of systemic insecticides during the crawler stage when the insects are most susceptible to chemical control.
