“…Several species complexes within the genus Oligonychus have been suggested by various authors in the past, for example a coffeae complex, pratensis complex, perseae complex, subnudus complex, sacchari complex, and ununguis complex (Pritchard and Baker 1955;Cromroy 1958;Meyer 1987;Ehara and Gotoh 2007;Lara et al 2017;Li et al 2018), and these are difficult to resolve based on morphology (Pritchard and Baker 1955). The coffeae complex sensu Ehara & Gotoh comprises (Ehara and Gotoh 2007).…”

“…Some species, e.g., O. caucasicus (Reck) and O. daleae Tuttle, Baker & Abbatiello, were reported as new to science, without making any remarks regarding related or similar species (Reck 1956;Tuttle et al 1976). This lack in clarity has resulted in the suggested existence of several species complexes within the genus Oligonychus e.g., coffeae complex and pratensis complex (Pritchard and Baker 1955;Meyer 1987;Ehara and Gotoh 2007;Lara et al 2017;Khanjani et al 2018;Li et al 2018). Consequently, there is a great need for developing an integrative taxonomic approach to clarify the actual status of many closely related Oligonychus species and for establishing truly diagnostic characters for accurate and consistent species separation.…”

A comprehensive taxonomic assessment of the most agriculturally important and highly diverse spider mite genus, Oligonychus Berlese (Acari: Tetranychidae) was performed. The sub-generic division, species groups, doubtful species, species complexes and the interpretation of a key generic character are discussed. Based on the orientation of the male aedeagus, only two subgenera, namely Oligonychus Berlese (aedeagus downturned) and Reckiella Tuttle & Baker (aedeagus upturned), are valid in the genus Oligonychus. The subgenera Homonychus Wainstein, Metatetranychoides Wainstein, and Wainsteiniella Tuttle & Baker are considered to be synonyms of the subgenus Oligonychus, whereas the subgenus Pritchardinychus Wainstein is proposed as a synonym of the subgenus Reckiella. Moreover, based on female morphological characters, four species groups (coffeae, exsiccator, iseilemae, and peruvianus) and 11 species subgroups (aceris, biharensis, coffeae, comptus, exsiccator, gossypii, iseilemae, peruvianus, pritchardi, smithi, and subnudus) are suggested in the subgenera Oligonychus and Reckiella. Fourteen Oligonychus species are proposed as species inquirendae, and potential cryptic species complexes in the genus Oligonychus are briefly highlighted. It is agreed that the clunal seta h1 is always absent, while the para-anal setae h2 and h3 are always present in the genus Oligonychus. A key to subgenera, species groups, and species subgroups of the genus Oligonychus is provided.

“…All the other known host plants for planting can be imported to the EU with a phytosanitary certificate (Implementing Regulation 2019/2072, Annex XI, Part A). The requirement of O. perseae for fresh foliage to survive means that the risk of O. perseae introduction associated with the movement of fruit is minimal (Lara et al, 2017 ; EPPO, 2008 ).…”

The EFSA Panel on Plant Health performed a pest categorisation of Oligonychus perseae (Acari: Prostigmata: Tetranychidae), the persea mite, for the EU. O. perseae is a tropical species that originated in Mesoamerica and has now spread and established in California, Florida, Hawaii, Morocco, southern Europe and Israel. Within the EU, it is established in Italy, Portugal and Spain. O . perseae is not listed in Commission Implementing Regulation (EU) 2019/2072. It is polyphagous, feeding on plants in 20 genera in 17 families. It is most frequently reported on avocado ( Persea americana ), where it is considered a key pest. No evidence was found indicating damage to other crops. O. perseae live on leaves and do not attack the fruit. Populations usually grow exponentially at the beginning of summer and decline at the end of this season. High population densities can cause severe defoliation, resulting in downgrading of fruit through sunburn. However, this type of damage is common only if trees additionally suffer from water stress. The lack of additional avocado pests in the EU, which facilitates the production of organic avocados, is jeopardised by the occurrence of this mite, as it may require pesticide applications. This is why O. perseae is considered an important pest of avocados in Spain, where more than 80% of EU avocado production occurs. Natural dispersal is restricted to neighbouring trees. However, human‐assisted movement can result in long‐distance spread. Plants for planting provide potential pathways for further entry and spread, including O. perseae ‐free EU MS where avocados are grown (i.e. Cyprus, France, Greece). Climatic conditions and availability of host plants in southern EU countries are conducive for establishment. Phytosanitary measures are available to reduce the likelihood of further entry and spread. O. perseae satisfies with no key uncertainties the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest.

“…Avocados are native to parts of México, and Central, and South America, where associated native insect biodiversity is high. In contrast, the biodiversity of the arthropod fauna associated with avocados in California is low, consisting primarily of about four invasive pest species of insects and mites that feed on leaves ( Lara et al 2017 ). Currently, California-grown avocados are free from specialist fruit feeding pests such as seed feeding weevils (e.g., the large avocado seed weevil, Heilipus lauri Boheman [Coleoptera: Curculionidae]) and moths (e.g., the avocado seed moth, Stenoma catenifer Walsingham [Lepidoptera: Elachistidae]).…”

Heilipus lauri Boheman (Coleoptera: Curculionidae) is a specialist pest of avocado fruit and is considered an incursion risk for U.S. avocado producers. At the time work reported here was undertaken the flight capabilities of H. lauri were unknown. Consequently, proactive studies were undertaken to quantify aspects of this pest’s flight capabilities to inform potential future control efforts. Flight mill studies were conducted in a quarantine laboratory to measure the dispersal capacity of H. lauri with respect to gender, mating status, and size on the single and repeat flight capabilities of weevils. Gender, mating status, and size did not significantly affect measured flight parameters. Average total distances flown and flight velocity, and mean maximum flight bout distances and durations significantly declined as weevil age increased and when weevils engaged in repeat flights. Survivorship rates were significantly reduced as the number of successive flights undertaken increased. The distribution of total average flight distances flown and total cumulative flight distances flown was platykurtic. The implications of these findings are discussed in terms of developing incursion management plans.
