Boules-à-mites suivi de Néoterroir, ruralité et autres mentries.
Boules-à-Mites, la partie création de cette thèse, est un recueil de poésie qui s’inscrit dans l’univers de Rivières-aux-Cartouches, une région fictive préalablement créée dans le recueil de nouvelles Rivières-aux-Cartouches : histoires à se coucher de bonne heure (2023), inspiré de la ruralité du …

Survey of Nasal Mites (Acari: Rhinonyssidae, Ereynetidae, Turbinoptidae) in Birds from Three States in the United States
<p>Avian nasal mites are obligate endoparasites that spend their entire life in the respiratory system of birds. In North America, bird nasal mites are represented by different unrelated families in three different orders of mites: Rhinonyssidae (Mesostigmata), Ereynetidae (Prostigmata), and the …

Ovicidal activity of methomyl on eggs of pest and beneficial insects and mites associated with apples in Virginia
… against eggs of pest and beneficial insects and mites associated with apples. The pest eggs studied were: Laspeyresia pomonella, Panonychus ulmi, Platynota spp., aphids, and Argyrotaenia velutinana. For A. velutinana, five rates of methomyl ranging from 0.013 to 0.204 kg ai/378.5 l water were …

Thermal biology and behaviour of two predatory Phytoseiid mites: Amblyseius swirskii (Athias-Henriot) (Acari:Phytoseiidae) and Phytoseiulus longipes (Evans) (Acari:Phytoseiidae)
Amblyseius swirskii and Phytoseiulus longipes are targeted as biological control agents for the horticultural pest Tetranychus urticae. This study applies a standardised protocol to evaluate the risk of establishment of introduced species and investigates temperature related behavioural thresholds …

Using selected acaricides to manipulate Tetranychus urticae Koch populations in order to enhance biological control provided by phytoseiid mites
… by growers to introduce predatory phytoseiid mites to manage twospotted spider mites and reduce their need for acaricide applications (Sabelis, 1981). The predatory mite Phytoseiulus persimilis Athias-Henriot has been used successfully in integrated pest management programs for T. urticae …

Changes in Gene Expression and Viral Titer in Varroa Jacobsoni Mites After a Host Shift Asian to European Honey Bees
… past two decades. Multiple species of parasitic mites have been described that affect honey bees. The most important species in beekeeping belong to the genus <em>Varroa</em> (<em> Varroa jacobsoni</em>and <em>Varroa destructor</em>). <em>Varroa</em> mite parasitism of honey bees is thought to be …

Effects of water mite parasitism on Cenocorixa spp. (Heteroptera: Corixidae)
… the mechanisms by which parasitic water mites exclude one species of sympatric water boatmen from low salinity, while a sibling species survives. Attachment of the larval water mite Eylaiseuryhalina Smith was studied in the laboratory on two species off light polymorphic water boatmen, …

<i>Neoseiulus fallacis</i> (Garman) (Acari: Phytoseiidae) as a potential biological control agent for spider mites (Acari: Tetranychidae) in Virginia vineyards
Outbreaks of spider mites (Acari: Tetranychidae) in vineyards have been increasing with the expansion of the industry in Virginia. Only three effective acaricides are registered on grapes and as resistance begins to occur, control options are limited. Biological control of spider mites by …

On the ecological transitions between parasitism and mutualism
… (Nicrophorus vespilloides) and their phoretic mites (the species complex Poecilochirus carabi) as a model symbiosis. I begin by showing that P. carabi is the most abundant mite species associating with burying beetles, and that it coexists with the mite Macrocheles nataliae. I show that each …

Toxicological Analysis of Acaricides for Varroa Mite Management
… bees, but resistance limits their use to reduce mites and diseases in bee colonies. Voltage-gated chloride channels are involved in the maintenance of nerve and muscle excitability in arthropod pests, which suggests that these channels might be exploited as targets for acaricides. Apistan® (the …

Ecology of Mite Phoresy on Mountain Pine Beetles
… the net effects of the phoresy observed in mites and mountain pine beetles (MPB), Dendroctonus ponderosae Hopkins. Using flight mills, I found that MPB flight increased with beetle size and body condition but was not modified by mite abundance. Mites were initially more abundant on larger …

Adrenal steroid, blocking agent, and social stress effects on northern fowl mite population development on Leghorn chickens and toxicological evaluation of selected acaricides (Acarina: <i>macronyssidae</i>)
… stress increased resistance of chickens to mites in a manner similar to but more effective than steroid administration. The mechanism of resistance was a decrease in capillary density at the skin surface. Commercial laying hens caged alone had lower plasma corticosterone levels and supported …

The Effect of Carpet Fiber on the Growth of Dermataphagiodes farniae in a Controlled Environment
Mites are endemic and allergy to mite excreta and parts is one of the most common allergies. Health care practitioners have recommended the removal of carpets from homes of people with mite allergies. Little, if any, consideration is given to the fact that some persons may benefit directly from the …
