Aculops ailanthii
Ailanthus leafcurl mite
Aculops ailanthii, commonly known as the Ailanthus leafcurl mite, is an eriophyid mite that infests Ailanthus altissima (tree-of-heaven). This species produces subtle leaf symptoms—undercurled, wrinkled, and glossier foliage—rather than the conspicuous galls typical of many eriophyid mites. The mites themselves are tiny, whitish, and difficult to locate on leaf undersides. The species has been proposed as a potential biocontrol agent against invasive Ailanthus populations in North America, though it remains poorly studied.

Anurida
Anurida is a genus of springtails (Collembola) in the family Neanuridae, established in 1865 by Laboulbène. The genus has cosmopolitan distribution with species occupying diverse habitats including intertidal marine zones, river floodplains, riparian areas, and forest ecosystems. Well-studied species include the intertidal specialist Anurida maritima, which exhibits complex tidal-entrained behaviors, and the terrestrial A. granaria, which has documented mycophagous associations. The genus shows notable morphological diversity in chaetotaxy and eye reduction, with some species groups exhibiting cryptic genetic divergence despite morphological similarity.

Arhopalus
burnt pine longhorn beetle (A. ferus), black pine sawyer (A. rusticus)
Arhopalus is a genus of longhorn beetles (Cerambycidae: Spondylidinae: Asemini) distributed across the Northern Hemisphere, with several species introduced to the Southern Hemisphere as invasive pests of conifers. The genus comprises approximately 20 described species, with A. rusticus and A. ferus being the most extensively studied due to their economic importance. Species develop in dead or fire-damaged conifer wood, with some exhibiting strong attraction to burnt pine volatiles. Several species produce male-emitted aggregation-sex pheromones containing fuscumol and geranylacetone. Invasive populations in New Zealand, Australia, South America, and South Africa require monitoring at ports and sawmills for timber export compliance.

Eriophyes mali
apple blister mite
Eriophyes mali is a microscopic eriophyid mite and a significant pest of apple orchards. It overwinters behind bud scales and initiates spring migration when midday temperatures exceed 10°C, developing two generations per growing season. The mite induces characteristic blister-like galls on apple leaves through its feeding activity, reducing yield and fruit quality. Field studies in Ukraine have demonstrated that targeted insecto-acaricide applications can reduce mite populations by 72.9–93.3% and improve orchard productivity.

Eriophyes pyri
pearleaf blister mite, pear leaf blister mite
Eriophyes pyri is a gall-forming eriophyid mite that attacks pear (Pyrus), apple (Malus), and plum (Prunus). Females overwinter beneath upper bud scales, emerging in spring when average daily temperatures exceed 10°C. The mite induces characteristic blister galls on young leaves by feeding on phloem sap, completing three generations per growing season in temperate regions. Population management through targeted pesticide applications can reduce mite numbers by 75–94% and improve fruit yield and quality.

Eurytetranychus
Eurytetranychus is a genus of spider mites (Tetranychidae) known primarily as pests of boxwood (Buxus species). The most notable species, Eurytetranychus buxi, feeds on boxwood foliage and has been identified as a significant arthropod pest in managed landscapes. Climate change may allow this mite to complete additional generations in warming regions, potentially increasing damage in areas where it was previously unproblematic.

Panonychus citri
Citrus Red Mite
Panonychus citri, commonly known as the citrus red mite, is a major agricultural pest of citrus orchards with a global distribution spanning Asia, the Mediterranean Basin, North America, South America, and Africa. The mite feeds by sucking cytoplasm from plant cells, causing chlorotic spots, premature leaf fall, brown skin discoloration, rough skin texture, and stunted fruit growth. Severe infestations can reduce fruit yields by up to 70%. The species has developed resistance to more than 23 pesticides due to extensive acaricide use, making integrated pest management strategies increasingly important. Research indicates that local factors, particularly citrus plant canopy density, significantly influence population dynamics more than landscape-scale factors.

Podapolipidae
Podapolipidae is a family of highly specialized mites (order Trombidiformes) that are obligate ectoparasites of insects, primarily beetles. Members inhabit protected microhabitats beneath host elytra or within body cavities. The family exhibits remarkable host specificity, with most species restricted to single host species. Transmission occurs primarily through sexual contact between hosts. The family includes notable genera such as Eutarsopolipus (parasitic on carabid beetles), Chrysomelobia (on chrysomelid beetles), and Coccipolipus (on ladybirds). Some species can negatively impact host fecundity and longevity, while others manipulate host behavior to enhance transmission.

Tarsonemidae
thread-footed mites, white mites
Tarsonemidae is a family of mites in the order Trombidiformes, commonly known as thread-footed mites or white mites. The family exhibits diverse feeding habits: most species feed on fungal mycelia or algal bodies, while a limited number of genera (Steneotarsonemus, Polyphagotarsonemus, Phytonemus, Floridotarsonemus, and Tarsonemus) feed on higher plants. Some tarsonemids are associated with insects, including parasites of bees (Acarapis woodi), associates of leaf-footed bug glands, and attachments to grasshopper wings. Several species are significant agricultural pests, notably the broad mite (Polyphagotarsonemus latus) and cyclamen mite (Steneotarsonemus pallidus).

Tetranychidae
Spider Mites
Tetranychidae is a family of mites commonly known as spider mites, comprising approximately 1,200 described species. Members are minute plant-feeding arachnids, typically measuring less than 1 mm in length. They are distributed worldwide and are significant agricultural pests, causing damage to hundreds of plant species by piercing leaf cells and extracting contents. Many species produce silk webbing for protection and dispersal. The family is divided into two subfamilies: Bryobiinae and Tetranychinae.

Tetranychinae
Tetranychinae is a subfamily of spider mites (Tetranychidae) containing economically significant agricultural and ornamental crop pests. The subfamily includes the genera Tetranychus, Eutetranychus, Oligonychus, Panonychus, Amphitetranychus, Schizotetranychus, Aponychus, Paraponychus, and Stylophoronychus. Species within this subfamily are phytophagous and pose serious threats to crop yield and quality. Identification relies primarily on morphological examination of adult male genitalia, though molecular and biochemical methods are increasingly employed for accurate species discrimination.

Tetranychus
spider mite
Tetranychus is a genus of spider mites (Family Tetranychidae) comprising over 140 described species, including some of the most economically destructive agricultural pests worldwide. The genus is characterized by haplodiploid reproduction, silk production, and rapid population growth under favorable conditions. Tetranychus urticae (two-spotted spider mite) is the most significant species, though T. evansi (tomato red spider mite) and T. ludeni have emerged as major invasive pests. These mites feed on plant cell contents, causing stippling damage, and are notoriously difficult to control due to their short generation times and ability to develop pesticide resistance.

Torrenticola
Torrenticola is a genus of water mites in the family Torrenticolidae, comprising over 400 described species globally and 90 species in North America alone. These mites are characteristic inhabitants of rocky and sandy streams, where they represent the dominant water mite genus. Recent taxonomic work has demonstrated that color markings, long overlooked by traditional acarology, serve as valuable diagnostic characters for species identification when combined with DNA sequencing and morphological analysis.

Varroa
Varroa Mites
Varroa is a genus of parasitic mesostigmatan mites that are obligate ectoparasites of honey bees (Apis spp.). The genus contains four species, with Varroa destructor being the most significant pest of Western honey bees (Apis mellifera) worldwide. Originally parasites of Asian honey bees (Apis cerana) in mainland Asia, these mites have spread globally through beekeeping activities. V. destructor is recognized as the most devastating pest of managed honey bees, causing colony losses through direct parasitism and by vectoring viruses such as deformed wing virus. The genus was named for Marcus Terentius Varro, a Roman scholar and beekeeper.

Varroidae
Varroidae is a family of parasitic mites in the order Mesostigmata, containing the economically significant genus Varroa. Members are obligate ectoparasites of honey bees (Apis spp.), with Varroa destructor being the most destructive species affecting managed European honey bee (Apis mellifera) colonies worldwide. These mites have a two-stage life cycle involving a phoretic traveling phase on adult bees and a reproductive phase within brood cells. The family has become a major focus of apicultural research due to the severe colony losses attributed to Varroa infestations, disease transmission, and the mites' role in honey bee population declines.

Zetzellia mali
apple mite, Zetzellia mite
Zetzellia mali is a predatory mite in the family Stigmaeidae, widely distributed across apple-growing regions of the world. This small arachnid serves as an important natural enemy of phytophagous mites in orchards, particularly targeting spider mites (Tetranychidae) and eriophyid mites. The species exhibits a three-generation annual life cycle in temperate climates, with adult females overwintering in protected locations on host trees. While less efficient at population regulation than some competing predatory mites such as phytoseiids, Z. mali contributes significantly to biological control in integrated pest management programs.
