Acalitus vaccinii (Keifer, 1939) is reported for the first time in South Africa, on cultivated blueberries (Ericaceae: Vaccinium spp.). This is the first known occurrence outside its likely native range in North America where it is a pest on cultivated and wild blueberries. In South Africa it has first been identified in 2014 and now occurs between Amsterdam and Lothair, and near Lydenburg and Dullstroom in the Mpumalanga Province. The morphology of the South African A. vaccinii specimens was compared with previous published taxonomic descriptions and differences were found. Infestation levels in South Africa were high, and reduced flower and berry formation considerably on various Vaccinium corymbosum L. cultivars, and on rabbiteye blueberry Vaccinium virgatum Aiton. 'Centurion'. The current status of, symptoms, and cultivars infested by the mite in South African blueberry plantings are presented and discussed in the context of published information in North America. Acalitus vaccinii is a potential threat to cultivated blueberries in South Africa, but the threat varies according to climate and the susceptibility of different cultivars to this mite. Acalitus vaccinii will unlikely infest South Africa’s indigenous vegetation, apart from possibly the native Vaccinium exul Bolus.

A new vagrant species of eriophyoid mite, Asetadiptacus acarubri n. sp., is described and illustrated from Rubus fruticosus (Rosaceae) in Britain, a key to the world species of Asetadiptacus is provided, and Anthocoptes rubicolens Roivainen and Trimeroptes rubi Bagdasarian are recorded from Britain for the first time. In addition, Acalitus essigi (Hassan) and Phyllocoptes gracilis (Nalepa) are reported from R. fruticosus and Rubus sp., respectively. Collection details, distribution and host plant symptoms are provided, together with digital micrographs of the prodorsal shield and coxigenital region of a female from each species discussed. A review of the other eriophyoid mite species hitherto recorded in Britain from Rubus is also provided.

Acalitus essigi (Hassan, 1928) (Fig. 1) Type host and locality. Hassan (1928) had not clearly specified the type host or locality but stated that A. essigi was first reported by Essig and Smith (1922) on Himalaya blackberry in California, USA. Keifer (1941) redescribed this species from Rubus vitifolius Cham. & Schlechtendal collected in Sacramento, California, to ���definitely characterize the red-berry mite���. Distribution. Widespread in Europe and the USA and also recorded from Australia, New Zealand, and Chile on many species of Rubus. Relation to the host. The feeding activity of A. essigi is the causal agent of ���red berry disease���, which results in incomplete, uneven ripening of the fruit, and is a particular problem for late maturing varieties (de Lillo & Duso, 1996). Collection data. England, Norfolk, Norwich, commercial plant nursery site, low numbers of adult females and males on R. fruticosus, 26.viii. 2009; England, Kent, Tonbridge, commercial plant nursery site, low numbers of adult females, males and nymphs on R. fruticosus, 07.x. 2009 and 12.xi. 2009. Remarks. The first record of eriophyoid mites causing ���red berry disease��� in England appears to have been made by Massee (1931), who recorded damage from East Malling, Kent, and Kirdford, West Sussex, and listed the host plants as wild and cultivated blackberries, loganberry and Himalaya berry, but did not provide any specific plant names. Massee (1961) confirmed A. essigi from slide mounted specimens and reported it from Rubus spp. from East Malling, Preston, Lancashire and Southfleet, Kent, and reported it as ���locally common���., Published as part of Pye, Daniel R. L. & Lillo, Enrico De, 2010, A review of the eriophyoid mites (Acari: Eriophyoidea) on Rubus spp. in Britain, with a new species (Diptilomiopidae) and two new records, pp. 15-26 in Zootaxa 2677 on pages 16-17, DOI: 10.5281/zenodo.199254, {"references":["Hassan, A.

The mite causes yellowish erineum on both the surface of the leaves. Etymology. The specific designation delhiensis is derived from the name of the area of collection, New Delhi. Remarks. This species resembles Acalitus epiphytivagrans (Mohanasundaram, 1983) described from an unknown epiphytic parasitic plant from Tamil Nadu, India, in having 7 rayed feather claw and similar dorsal shield design, but differs in not having antapical setae, absence of accessory seta, microtubercles oval, reducing in size caudally and genital cover flap design which has coarse granules and absence of prominent crescentic scorings. A. epiphytivagrans has antapical seta, accessory seta, microtubercles oval to elongate along the posterior margin of each ring and genital cover flap shows 3���4 pairs of crescentic scorings. Further, this new species causes yellowish erineum on both surface of leaves, whereas, A. epiphytivagrans has been reported as vagrant on leaf surface, causing slight crinkling of leaves., Published as part of Menon, Pratibha & Joshi, Sushila, 2009, Two new species of eriophyid mites (Acari: Eriophyidae) from India, pp. 62-68 in Zootaxa 2067 on pages 65-67, DOI: 10.5281/zenodo.187009, {"references":["Mohanasundaram, M.

Four species of phytophagous mites are reported from Guadeloupe and Marie Galante: a spider mite, Tetranychus gloveri Banks, one eriophyid mite, Acalitus maracai (Boczek & Nuzzaci) and two new species of Eriophyidae, namely Acalitus macrosetosus n. sp. from Dalbergia ecastaphyllum (Fabaceae) and Aceria geniculatus n. sp. from Inga laurina (Mimosaceae).
