Ontogenetic modification in the Tuckerellidae (Acari: Tetranychoidea)

Abstract

We confirm the ancestral prostigmatic condition of three nymphal stages during ontogeny, i.e. the retention of a tritonymph, for three species of Tuckerella (Acari: Tuckerellidae), T. japonica Ehara, T. filipina Corpuz-Raros and T. ornata (Tucker). In addition, we demonstrate that this primitive condition is not retained for males of at least two species, T. saetula Chaudhri and T. nr pavoniformis, in which the male is shown to emerge from the deutonymph.

Redescription of Bryobia pritchardi Rimando, 1962 (Acari: Tetranychidae), with an ontogeny of chaetotaxy

“…Recently great importance has been attached to understanding the patterns of setal additions throughout ontogenetic development of the Tetranychoidea (Khanjani et al 2018;Seeman et al 2017;Li et al 2018Li et al , 2017Xu et al 2017;Yi et al 2017Yi et al , 2013De Castro et al 2015;Beard & Ochoa 2010;Beard & Walter 2010). There are few scholars who have payed attention to the ontogenetic patterns for species of Bryobia.…”

External morphology of the mouthparts and observations on behavior of Tuckerella japonica on Camellia sinensis in the continental USA

“…The family Tuckerellidae consists of a single genus, Tuckerella Womersley, and a key to species was provided by Smith Meyer and Ueckermann ( 1997 ). Twenty-eight species were reported by Zhang et al ( 2011 ) whereas 29 species were listed by Beard and Ochoa ( 2010 ). Increased interest in tuckerellid mites has evolved given their presence on fruits, leaves and stems of imported plants (Beard et al 2013 ).…”

The missing stase in spider mites (Acari: Tetranychidae): when the adult is not the imago.

“…A second intermediate case is provided by Tuckerella saetula and T. cf. pavoniformis in which the male directly emerges from the deutonymph (Beard and Ochoa, 2010).…”
