A predator-prey system: Phytoseiulus persimilis (Acari: Phytoseiidae) and Tetranychus urticae (Acari: Tetranychidae): worldwide occurrence datasets

Alain Migeon, Marie-Stéphane Tixier, Maria Navajas, Vassilis D. Litskas & Menelaos C. Stavrinides
The predator-prey system Phytoseiulus persimilis Athias-Henriot (Acari: Phytoseiidae) and Tetranychus urticae (Koch) (Acari: Tetranychidae) represents the most studied and the most known system among the Acari. Because of the agronomical importance of the two mite species, a wealth of modelling studies investigated the interactions of the two species at the individual level. However, regional or global level works on this system are lacking, which is impeding the investigation of climate change effects on biological control...

An amazing sub-cambium flat mite from South Africa (Acari: Trombidiformes: Tenuipalpidae)

Edward A. Ueckermann, Ronald Ochoa, Gary R. Bauchan & Stefan Neser
An unusual sub-cambium flat mite, Phytoptipalpus occultuae sp. n., first found under the bark in blisters on stems of Senegalia caffra in Pretoria, South Africa is described and illustrated herein. This is a unique species in the genus Phytoptipalpus because of the presence of reduced legs IV, a possible link between those with 4 pairs and 3 pairs of legs. A key to all of the Phytoptipalpus species is given.

Effects of temperature on a Chinese population of Amblyseius andersoni (Acari: Phytoseiidae) fed with Tetranychus urticae

Yu-Jing Li, Qing-Yan Liu, Jing Chang, Yong-Hong Jia & Rui-Xia Meng
The development and fecundity of Amblyseius andersoni (Chant) fed with Tetranychus urticae Koch was studied at five different temperatures (17, 20, 25, 30 and 35 °C) and life parameters of the population were calculated. The development, reproduction, longevity, and life table parameters of A. andersoni were significantly affected by the different temperatures. The duration of the egg, larval, protonymph, deutonymph and total immature stages were reduced when the temperature increased. The total oviposition of A....

Climatic and cultivar effects on phytoseiid species establishment and seasonal abundance on citrus

Sharon Warburg, Roni Gafni, Moshe Inbar, Shira Gal, Eric Palevsky & Asaf Sadeh
The structure of phytoseiid communities on citrus varies among orchards and seasons, with potential implications for biocontrol services. Such variation may be driven by meteorological conditions and cultivar-specific traits. We conducted an outdoor seedling experiment to determine the effects of different cultivars on the establishment of introduced predatory mites (Euseius stipulatus and E. scutalis) and colonization by naturally occurring phytoseiids (Amblyseius swirskii, Iphiseius degenerans, and Typhlodromus athiasae) across seasons. Euseius stipulatus persisted through the spring...

Marta I. Saloña Bordas & M. Alejandra Perotti
We report for the first time the presence of Poecilochirus mrciaki Mašán, 1999 in the South of Europe, in the Iberian peninsula and on new carrier insects. Mites were collected from carrion insects, during a decomposition experiment carried out in the natural park “Aiako Harria” (Errenteria, Gipuzkoa). Most deutonymphs were found on the body of the necrophagous beetle Necrodes littoralis (Coleoptera, Silphidae). Other species of insects in families Geotrupidae, Staphylinidae (Coleoptera) and Calliphoridae (Diptera) were...

A new mite species of the genus Neottialges (Acariformes: Hypoderatidae) from the black stork Ciconia nigra (Ciconiiformes: Ciconiidae) in Portugal

Sergey V. Mironov & David W.R. Ramilo
Deutonymphs of hypoderatid mites (Astigmata: Hypoderatidae) are subcutaneous parasites of various groups of birds and some rodents. A new hypoderatid mite species, Neottialges (Caloenectes) ciconiae n. sp., is described from the black stork, Ciconia nigra (Ciconiiformes: Ciconiidae), in Portugal. The new species is most similar to but differs from N. (C.) distinctus Fain and Lawrence, 1986 in having smaller prodorsal and hysteronotal shields not encompassing bases of setae si, se, cp, c2, e2 and h1,...

A new species of Arrenurus (Acari, Parasitengona, Hydrachnidia) found in the crop of a Yellow-billed Teal Anas flavirostris in Bolivia

Antonio G. Valdecasas
New findings of organismal dispersal by other organisms can help explain the distribution of species to remote places. In this work, I describe a male and a female of a new water mite species of the genus Arrenurus that were found in the crop of an Anas flavirostris duck near Cochabamba, Bolivia. Both specimens were complete; however, it is unknown if they were alive and, thus, potentially viable at the time of collection. This study...
