Avocado Bud Mite
Tegolophus perseaflorae (Acari: Eriophyidae)
The adult avocado bud mite has a yellowish appearance. Its life cycle has not been determined. Avocado bud mite populations begin to increase from March to May (Peña and Johnson, 1999).
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).
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
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).
