immigration of phytoseiid mites from surrounding uncultivated areas into a newly planted vineyard.this study reports (1) a faunistic survey of phytoseiid mites observed inside a vine plot and in neighbouring vegetation (other vine plots and uncultivated areas) and (2) dispersal of phytoseiid mites into the plot studied. these data aim to raise some hypotheses concerning natural colonisation of a vineyard by predatory mites. the study was carried out over 3 years (1999, 2000 and 2001) in an experimental plot planted with two cultivars (grenache and syrah) and with sorbus domestica in a framew ...200616804768
mite diversity (acari: tetranychidae, tydeidae, iolinidae, phytoseiidae) and within-tree distribution in citrus orchards in southern spain, with special reference to eutetranychus orientalis.mite diversity of selected citrus orchards in andalusia (southern spain) was studied during 2002-2007. the following species were found: eutetranychus orientalis, tetranychus urticae, panonychus citri (tetranychidae), tydeus californicus, lorryia formosa (tydeidae), pronematus ubiquitus (iolinidae), euseius stipulatus, typhlodromus phialatus, neoseiulus californicus, euseius scutalis, phytoseiulus persimilis, paraseiulus talbii and neoseiulus cucumeris (phytoseiidae). eutetranychus orientalis wa ...201729022207
isolation and characterization of polymorphic microsatellite markers in tetranychus urticae and cross amplification in other tetranychidae and phytoseiidae species of economic importance.tetranychus urticae koch is a cosmopolitan phytophagous mite considered as the most polyphagous species among spider mites. population genetic studies using molecular markers such as microsatellites have proven to be extremely informative to address questions about population structure, phylogeography and host preferences. the aim of this study was to increase the available molecular tools to gain insight into the genetic structure of t. urticae populations of citrus orchards, which might help i ...201222349944
assessment of pesticide susceptibility for typhlodromus exhilaratus and typhlodromus phialatus strains (acari: phytoseiidae) from vineyards in the south of france.two species of phytoseiidae predominated in and around vineyards in an experimental site in the south of france: typhlodromus exhilaratus is the dominant species on grapes, whereas t. phialatus occurs in the uncultivated areas surrounding these crops. to help understand their distribution, this study aims to determine their susceptibility to a fungicide (dimethomorph + mancozeb) and an insecticide (chlorpyriphos-ethyl), which have been widely used at the experimental site for at least four years ...200717564789
cannibalism and intraguild predation in typhlodromus exhilaratus and t. phialatus (acari: phytoseiidae) under laboratory conditions.two species of phytoseiidae are found in the same agroecosystem: typhlodromus exhilaratus prevails in vine plots, while t. phialatus prevails in uncultivated surrounding areas. the objective of the present paper was to investigate whether the poor settlement of t. phialatus in vine plots can be explained by intraguild predation of these two species and/or cannibalism. predatory abilities of the females on larvae and protonymphs were studied under laboratory conditions. a first experiment was con ...200717225961
