Impacts of male-killing Spiroplasma on the metabolic rate and ectoparasite resistance capacity (endurance) of Drosophila
<p>Ectoparasitic mites are hypothesized to horizontally transmit bacterial endosymbionts, especially male-killing Spiroplasma. In this study we test how <em>Spiroplasma poulsonii </em>MSRO affects fly physiology and behaviour, and potential mite interactions.</p>
Phototaxic Behaviour of Flies with and without an ectoparasitic mite
<p>First, we demonstrated that flies are less likely to be infected by mites when exposed in light environments than dark environments using micro-arena experiments. In baseline conditions (mite-free environments), unmated female flies and mated female flies spent significantly more time in the dark side of the phototaxis chambers. Males did not show significant negative or positive phototaxis. Contrarily, when exposed to mites, neither unmated or mated females displayed significant phototaxis. Flies became less negatively phototaxic when threatened with mites, suggesting phototaxis is a mechanism of behavioural immunity.</p>
Microclimate and host body condition influence mite population growth in a wild bird-ectoparasite system
<p>Parasite populations are never evenly distributed among the hosts they infect. Avian nest ectoparasites, such as mites, are no exception, as their distribution across the landscape is highly aggregated. It remains unclear if this pattern is driven by differences in transmission events alone, or if the environment that parasites inhabit after transmission also plays a role. Here, we experimentally examined the influence of the post-transmission microclimate, nest characteristics, and host condition on ectoparasite population growth in a bird-ectoparasite system. We infested barn swallow (Hirundo rustica erythrogaster) nests with a standardized number of Northern Fowl Mites (Ornithonyssus sylvarium) and analyzed both biotic (nestling mass, wing length, number of other arthropods present in the nest, and brood size) and abiotic (temperature, humidity, nest lining, nest dimensions, and substrate upon which the nest was built) predictors of mite population growth. Our results suggest that mite populations were most successful, in terms of growth, in nests with higher temperatures, lower humidity, few other arthropods, and hosts in good condition. We also found that nests built on wooden substrates support larger populations of mites than those constructed on metal or concrete. These findings lend insight into the factors that drive large-scale patterns of ectoparasite distributions.</p>
