Mites of the genus Typhlodromus (Acari: Phytoseiidae) from Southern France: combined morphological and molecular approaches for species identification.
Zootaxa, 2019Co-Authors: Marie-stéphane Tixier, Serge Kreiter, Principato Dennj, Martial Douin, Tsolakis HaralabosAbstract:Mites of the family Phytoseiidae are important predators for biological control applications. They occur naturally in ecosystems but their overall distribution is not completely known. This study presents results of surveys carried out in the south of France. It proposes the use of a combination of morphological and molecular approaches for species diagnosis. Eighteen species of the genus Typhlodromus are reported from southern France, of which nine belong to Typhlodromus (Anthoseius) and nine to Typhlodromus (Typhlodromus). Eight of these species are new to the French fauna. The mitochondrial DNA CytB gene from 85 specimens (18 species) and the 12S rRNA gene from 30 specimens (9 species) were partially sequenced and analysed. Based on molecular and morphological comparisons, the synonymy between Typhlodromus (Anthoseius) ilicis and T. (A.) creticus is discussed. High genetic distances between specimens morphologically assigned to T. (A.) rhenanoides suggests the existence of cryptic species. The reliability of integrative approaches for species identification is discussed.

Phytoseiidae (Acari: Mesostigmata) of Morocco: new records, descriptions of five new species, re-descriptions of two species, and key for identification
Zootaxa, 2016Co-Authors: Marie-stéphane Tixier, Martial Douin, Latifa Allam, Serge KreiterAbstract:The family Phytoseiidae includes more than 2,300 species distributed all over the world. However despite the huge numbers of faunistic surveys carried out for more than 60 years, the fauna of some countries and particular ecosystems remain little explored. This paper reports results of surveys carried out in various regions of Morocco (from Sahara to Atlantic and Mediteranean coasts) in 2002 and 2003. A total of 43 species was found. Among them 19 are new for the Moroccan fauna and five are new to science. This paper provides the descriptions of these five new species, Neoseiulus thymeleae, Transeius audeae, Typhlodromus (Typhlodromus) ballotae, T. (T.) leclanti, T. (T.) mazarii, and re-descriptions of two species (Typhlodromus (T.) setubali and Typhlodromus (Anthoseius) clairathiasae. A key to females of the 52 species now known from Morocco is given.

Phytoseiid mite diversity (Acari: Mesostigmata) and assessment of their spatial distribution in French apple orchards
Acarologia, 2014Co-Authors: Marie-stéphane Tixier, Ivson Lopes, Guy Blanc, Jean-luc Dedieu, Serge KreiterAbstract:The present study reports the results of surveys carried out over two years in 173 apple orchards in France. Eleven species of Phytoseiidae were observed, among them three were dominant: Amblyseius andersoni, Kampimodromus aberrans and Typhlodromus (Typhlodromus) pyri. Cydnodromus californicus was also found but only in some orchards and nearly always in association with one of three dominant species. This observation confirms the faunal modification initiated more than ten years ago. Amblyseius andersoni was recorded in high densities in nearly all the regions considered. Typhlodromus (T.) pyri was also widespread, even if particularly frequent and abundant in the Rh¶ne-Alpes region. Kampimodromus aberrans was localised in some regions; it was especially frequent and abundant in the Mediterranean region. An identification key containing the eleven reported species is provided. TaylorÆs law was applied in order to characterize the Phytoseiidae distribution in apple orchards. The distribution is clearly aggregative, whatever the region and the Phytoseiidae species considered. Relationships between the occupation rate and the mean number of Phytoseiidae per leaf was established and an abacus was constructed to facilitate surveys and the counting during practical assessments of Phytoseiidae fauna in apple orchards.

Redescription of six species of the genus Typhlodromus Scheuten (Acari: Phytoseiidae: Typhlodrominae) recorded from some regions of Western and North–Western Iran
persian journal of acarology, 2013Co-Authors: Bahman Asali Fayaz, Mohammad Khanjani, Marie-stéphane TixierAbstract:Collects of Phytoseiidae species of the genus Typhlodromus Scheuten have been carried out in some regions of Western and North–Western Iran from 2008–2011. This paper presents the redescription of six species belonging to two subgenera Typhlodromus ( Anthoseius ) De Leon and Typhlodromus ( Typhlodromus ) Scheuten (each with three species, respectively): T. ( A. ) bagdasarjani Wainstein & Arutunjan, T. ( A. ) kerkirae Swirski & Ragusa, T. ( A. ) khosrovensis Arutunjan, T. ( T. ) phialatus Athias–Henriot, T. ( T. ) leptodactylus Wainstein and T. ( T. ) tubifer Wainstein. It is the first record of T. ( T. ) phialatus Athias–Henriot for the Iranian phytoseiid fauna. This paper also provides an identification key of the species of the genus Typhlodromus in Iran.

Phytoseiidae in European grape (Vitis vinifera L.): bio-ecological aspects and keys to species (Acari: Mesostigmata)
Zootaxa, 2013Co-Authors: Marie-stéphane Tixier, Carlo Duso, Andrea Baldassar, Serge KreiterAbstract:The family Phytoseiidae includes many species of predators involved in the control of mite pests of crops all over the world. In European vineyards, these natural enemies play a key role in plant protection as their presence usually makes the use of acaricides unnecessary. Each species has its specific biological features. It is thus of great interest to identify the species reported on grape, Vitis vinifera. The present paper, based on a world database of the family Phytoseiidae and on an analysis of more than 250 publications, presents the 54 species of Phytoseiidae belonging to 15 genera reported on V. vinifera in Europe, and identification keys to species. Online versions of the key (dichotomous and polytomous) with illustrations are available at http://www1.montpellier.inra.fr/CBGP/phytoseiidae/sitewebvineyards2/index.htm. An analysis of the biogeographic distribution of these species and their prey has also been carried out. Most species reported on V. vinifera in Europe are rare; only five species are frequently observed: Kampimodromus aberrans, Typhlodromus (Typhlodromus) pyri, Typhlodromus (Typhlodromus) exhilaratus, Euseius finlandicus and Phytoseius finitimus. The 12 countries where Phytoseiidae have been reported from grapes have been unevenly surveyed, the most well-known faunas being from Italy, Greece and France. These species are reported to prey upon the main species of mite pests of grapes.

Obtaining molecular data for all life stages of Typhlodromus (Typhlodromus) exhilaratus (Mesostigmata: Phytoseiidae)
Experimental and Applied Acarology, 2012Co-Authors: Mireille Okassa, Serge Kreiter, Marie-stéphane TixierAbstract:Several species of the family Phytoseiidae are known to control mite pests in many crops worldwide. However, biological control success greatly depends on the accurate identification of these predatory mites. Species diagnostics is essentially based on the morphological characters of females. Thus, when only immature stages and/or males are collected, their identification is poorly supported. Molecular tools could be of great help to overcome these difficulties, as molecular sequences are assumed to be identical for the life stage considered. However, one of the essential points is to extract a sufficient DNA amount from a single specimen of immature stages (eggs, protonymphs, deutonymphs) and males (less than 300 mu m in length) to amplify and sequence DNA. The markers used were two mitochondrial DNA fragments (12S rRNA and Cytb mtDNA) and the species studied were Typhlodromus (Typhlodromus) and T. (T.) phialatus , two cryptic species, reported to control mite pests in crops of southern Europe and commonly found on the same plants. Despite a low quantity of DNA extracted, particularly for the egg, larva and protonymph stages, DNA was amplified and sequences were obtained from all the life stages considered with the two mtDNA fragments. Sequences from all the developmental stages of T. (T.) were identical and well differentiated from those of its sister-species. However, contaminations were observed especially for eggs and DNA amplified with the Cytb mt marker. Utility of the present results are discussed and protocol improvements are proposed.
