Bulb Mites (Rhizoglyphus spp.)
Soil and bulb-dwelling mites feeding on bulb tissue, roots and basal plates.
Bulb mites (Rhizoglyphus and related genera) attack lilies, alliums, ornamentals and stored bulbs. They feed on damaged or weakened tissue but can rapidly spread and predispose bulbs to rot. Infested bulbs show poor emergence, stunting and rotting basal plates. Biological control includes soil predatory mites such as Stratiolaelaps (Hypoaspis) and entomopathogenic fungi, combined with strict hygiene, discarding heavily infested stock and avoiding prolonged damp storage.
