Ueckermann to acarology P.D. THERON1 & G.J. DE MORAES2 1Research Unit for Environmental Sciences and Development; North-West University, Potchefstroom, South Africa 2Depto. Entomologia e Acarologia; Escola Superior de Agricultura Luiz de Queiroz, Universidade de São Paulo; Piraci- caba, SP, Brazil Acarology has been a very active area of research in South Africa for many years, especially with reference to taxonomy. For this reason, mites of agricultural importance are well known in that country compared to many other countries. Edward A. Ueckermann is a South African acarologist who has contributed enormously to knowledge about the mites of his country, as well as from many other countries around the world. Eddie, as he is called by his friends, is an admirable man, both for his enviable professional qualities and for his tremendous personality. The authors of this brief biography are glad to have had the opportunity to collaborate with Eddie as authors of several publications51, 52, 58, 70, 75, 80, 87, 92, 95, 101,103, 104, 107, 112, 114, 117, 121, 143, 151, 160, 189, 203, 207, 211, and to interact with him in many other ways. Eddie was born in Postmasburg, Northern Cape Province, South Africa, on 19 January 1951. He completed secondary school in his hometown and after a year of compulsory military training, Eddie enrolled at North- West University, Potchefstroom, in 1971 to study a B.Sc.

New records of mites of the family Bdellidae are reported from caves in Brazil. Keywords: Acari; Bdellidae; Cyta; snout mites; cave; Brazil Introduction The snout mites of the family Bdellidae Dugès (Acari: Trombidiformes) are active predators of small arthropods and their eggs (Alberti 1973; Gerson et al. 2003), commonly found on soil litter, moss, lichens and similar microhabitats in epigean environments. Although bdellids have been collected in almost every continent, few species were described or even reported from South America. Recently, four species were described from plants in Brazil (Hernandes and Feres 2006; Hernandes et al 2007, 2008): Tetrabdella neotropica Hernandes and Feres, Hexabdella cinquaginta Hernandes, Daud and Feres, Bdella ueckermanni Hernandes, Daud and Feres and Spinibdella denheyeri Hernandes, Daud and Feres. Notwithstanding, little is known regarding the bdellids of caves and their probable associations with other inhabitants of these environments.

PAPER INFO.: Received: 10 September 2018, Accepted: 2 October 2018, Published: 15 October 2018 INTRODUCTION Because of their cone like gnathosoma projecting from between palp bases, Bdellidae Dugès (Acari: Trombidiformes: Bdelloidea) are known as snout mites. They are active predators (Gerson et al. 2003) feeding on tiny arthropods such as springtails (Wallace and Mahon 1972), oribatids (Alberti 1973), tetranychid mites, and other agricultural pests (Dean 1952; Gerson and Smiley 1990; Ireson et al. 2002; Gerson et al. 2003). Bdella was erected by Latreille (1795) with type species Bdella longicornis [syn.: Acarus longicornis Linnaeus, 1758]. Members of this genus were recorded from all biogeographic regions (Hernandes et al. 2016). To date, 54 species have been recorded world- wide (Atyeo 1960; Wallace and Mahon, 1972; Swift and Goff, 1987; van der Schyff et al.

However, chemical use can have unintended effects on natural enemies, which can play a key role in suppressing and controlling pest outbreaks within crops. We undertook a literature review of studies that have conducted chemical toxicity testing against arthropod natural enemies relevant to the Australian grains industry to examine trends and highlight research gaps and priorities. Most toxicity trials have been conducted in the laboratory, with few at larger, and hence, industry-relevant scales. Researchers have used a variety of methods when conducting toxicity testing, making it difficult to compare within and across different species of natural enemies. Furthermore, we found many gaps in testing, leading to unknown toxicity effects for several key natural enemies, some of which are economically important predators and parasitoids. Through our review, we make several key recommendations for future areas of research that could arm farmers and their advisors with the knowledge they need to make informed decisions when it comes to controlling crop pests.

  • Linking Morphological and Molecular Taxonomy for the Identification of Poultry House, Soil, and Nest Dwelling Mites in the Weste
    www.nature.com/scientificreports OPEN Linking morphological and molecular taxonomy for the identifcation of poultry house, Received: 27 October 2018 Accepted: 20 March 2019 soil, and nest dwelling mites in the Published: xx xx xxxx Western Palearctic Monica R. Young 1, María L. Moraza2, Eddie Ueckermann3, Dieter Heylen4,5, Lisa F. Baardsen6, Jose Francisco Lima-Barbero 7,8, Shira Gal9, Efrat Gavish-Regev 10, Yuval Gottlieb11, Lise Roy 12, Eitan Recht13, Marine El Adouzi12 & Eric Palevsky9 Because of its ability to expedite specimen identifcation and species delineation, the barcode index number (BIN) system presents a powerful tool to characterize hyperdiverse invertebrate groups such as the Acari (mites). However, the congruence between BINs and morphologically recognized species has seen limited testing in this taxon. We therefore apply this method towards the development of a barcode reference library for soil, poultry litter, and nest dwelling mites in the Western Palearctic. Through analysis of over 600 specimens, we provide DNA barcode coverage for 35 described species and 70 molecular taxonomic units (BINs). Nearly 80% of the species were accurately identifed through this method, but just 60% perfectly matched (1:1) with BINs. High intraspecifc divergences were found in 34% of the species examined and likely refect cryptic diversity, highlighting the need for revision in these taxa. These fndings provide a valuable resource for integrative pest management, but also highlight the importance of integrating morphological and molecular methods for fne-scale taxonomic resolution in poorly-known invertebrate lineages. DNA barcoding1 alleviates many of the challenges associated with morphological specimen identifcation by comparing short, standardized fragments of DNA – typically 648 bp of the cytochrome c oxidase I (COI) gene for animals – to a well-curated reference library.
