Damage
Part of plant damaged: Leaves, buds
In Florida, the avocado bud mites were observed feeding on buds, causing necrotic spots on apical leaves, and subcircular, irregular openings on mature leaves. Mites were also found in petioles, the underside of leaves and fruitlets. This mite is also reported to feed on the peduncle, calyx and stylar area (Medina et al. 1978, Jeppson et al. 1975). -
Management
Monitoring
Mites are occasional pests in some orchards and are seldom observed in others. Periodic inspections are recommended during December, January and February using a hand lens.
Chemical Control
In Florida, few miticides are registered for use on avocados when fruit is present. Sulfur or oil emulsion sprays are recommended (Peña and Johnson, 1999).
