Tetranychinae

Species identification relies heavily on morphological examination of male genitalia, particularly the aedeagus. This method is complicated by the small size of specimens, limited number of diagnostic features, and the inability to identify immature stages or females to species. Molecular methods including DNA barcoding, PCR-RFLP, species-specific primers, real-time PCR, and LAMP provide alternative approaches. Biochemical methods such as allozyme analysis and MALDI-TOF MS have been successfully applied. The greatest accuracy is achieved through combined morphological and molecular approaches. Genetic incompatibility and reproductive barriers serve as supplementary species discrimination criteria through crossing experiments.

Agricultural crops, ornamental woody and herbaceous plants, and natural vegetation. Specific habitats include apple orchards, rosaceous plantings, Quercus woodlands, and coniferous plantings in urban areas. Paleotropical species of Aponychus, Paraponychus, and Stylophoronychus are mainly associated with monocotyledons, while Neotropical and North American species of these genera are associated with dicotyledons.

Worldwide distribution with notable expansion into new regions. Documented in Turkey (Ankara), Russia (including Krasnodar Region with expanding urban coniferous plantings), Paleotropical region, Neotropics, and North America. Some species exhibit invasive behavior with quarantine risk through international plant trade.

Active from April to October in temperate regions such as Ankara, Turkey. Weekly sampling during this period detected consistent presence of abundant species.

Phytophagous; feeds on vascular plants across multiple botanical families. Specific hosts include Malus domestica, Prunus domestica, Prunus avium, Prunus armeniaca, Prunus mahaleb, Quercus species, Picea species, Abies sibirica, and various other agricultural and ornamental crops.

Includes eggs, larvae, nymphs, and adults. Diapausing phase present in some species. Wintering sites vary by species. Morphological diagnostic features for species identification exist only in the adult stage, particularly in males.

Species concentrate feeding on certain organs of host plants, producing species-specific damage symptoms. Exhibits invasive behavior with documented expansion of distribution areas and increased harmfulness in new regions. Some populations have developed acaricide resistance.

Serious agricultural pest causing significant damage to crop yield and quality. Reduces plant drought resistance and winter hardiness. Poses threat to phytosanitary status of agro- and biocenoses. Some species carry quarantine status due to international trade risks.

Major economic pest of agricultural and ornamental crops. Requires active management through integrated pest management strategies. Identification challenges complicate monitoring and control efforts. International plant trade facilitates spread of invasive species with quarantine implications.

• BryobiinaeBoth are subfamilies of Tetranychidae; Bryobiinae species such as Bryobia rubrioculus, B. praetiosa, and Bryobia sp. co-occur with Tetranychinae in the same habitats but lack the male aedeagal structures diagnostic for Tetranychinae species identification.
