Aculops is a of eriophyid mites comprising parasitic plant-feeding . Several members are significant agricultural pests, including Aculops lycopersici (tomato russet mite) and Aculops cannabicola (hemp russet mite). The genus also includes species under consideration for , such as Aculops ailanthii for management of tree-of-heaven (Ailanthus altissima). within Aculops remains incompletely documented, with new species continuing to be described.

Habitat

Associated with aboveground plant tissues; occupy diverse plant environments including agricultural crops, ornamentals, and wild plants. Specific microhabitat preferences vary by species.

Distribution

distribution with records from Europe, Africa, Asia, Australasia, Pacific Islands, and North America. Distribution patterns reflect plant availability and human-mediated transport of agricultural pests.

Diet

Phytophagous; feed on epidermal of stems and leaves. Specific associations vary: A. lycopersici infests Solanaceae including tomato, potato, eggplant, and tobacco; A. cannabicola specializes on Cannabis sativa; A. fuchsiae occurs on Fuchsia species; A. ailanthii occurs on Ailanthus altissima.

Host Associations

  • Solanum lycopersicum (tomato) - primary A. lycopersici
  • Solanum tuberosum (potato) - A. lycopersici
  • Solanum melongena (eggplant) - A. lycopersici
  • Solanum nigrum (black nightshade) - alternative A. lycopersici; supports higher than tomato
  • Nicotiana tabacum (tobacco) - A. lycopersici
  • Capsicum annuum (bell pepper) - A. lycopersici
  • Petunia hybrida (petunia) - A. lycopersici
  • Ipomoea batatas (sweet potato) - A. lycopersici
  • Convolvulus arvensis (field bindweed) - A. lycopersici
  • Cannabis sativa (hemp) - primary A. cannabicola
  • Fuchsia spp. - primary A. fuchsiae
  • Ailanthus altissima (tree-of-heaven) - primary A. ailanthii

Ecological Role

Agricultural pests causing direct plant damage through epidermal feeding; some may serve as agents against plants. A. lycopersici can cause over 65% crop loss in tomatoes under heavy . Black nightshade acts as facilitating pest persistence between crop cycles.

Human Relevance

Economic impact through damage to tomato, hemp, and ornamental crops. A. lycopersici and A. cannabicola are managed through including chemical control and conservation of predatory mites. A. ailanthii is being evaluated as biocontrol agent for tree-of-heaven in North America.

Taxonomic Status

The remains taxonomically active with new descriptions continuing, particularly from under-surveyed regions such as New Zealand.

Research Gaps

Basic is unknown for most ; research has concentrated on economically significant pests, leaving the majority of the poorly characterized.
