Data from: Introduced bees (Osmia cornifrons) collect pollen from both coevolved and novel host-plant species within their family-level phylogenetic preferences
<p><span><span><span><span><span><span><span><span><span><span><span>Studying the pollen preferences of introduced bees allows us to investigate how species utilize host-plants when establishing in new environments. <i>Osmia cornifrons</i> is a solitary bee introduced into North America from East-Asia for pollination of crops in the Rosaceae. We investigated whether <i>O. cornifrons</i> 1) more frequently collected pollen from host-plant species they coevolved with from their geographic origin, or 2) prefer hosts-plant species of specific plant taxa independent of origin. To address this question, using pollen metabarcoding we examined the identity and relative abundance of pollen in larval provisions from nests located in different habitats with varying abundance of East-Asian and non-Asian plant species. Our results show that <i>O. cornifrons</i> disproportionately, yet not exclusively, collected pollen from their native range. Plants in the family Rosaceae were their most preferred pollen hosts, where they differentially collected species native to East-Asia, Europe, or North America depending on the landscape. Our results suggest that while <i>O. cornifrons</i> more frequently collect pollen of East-Asian origin, the collection of pollen from novel species within their phylogenetic familial affinities can facilitate pollinator establishment. This phylogenetic preference highlights the effectiveness of <i>O. cornifrons</i> as crop pollinators of a variety of Rosaceae crops from different geographic origins. Ourresults imply that globalization of non-native plant species may ease the naturalization of their coevolved pollinators outside of their native range. </span></span></span></span></span></span></span></span></span></span></span></p>
Host preferences inhibit transmission from potential superspreader host species
<p>Host species that are particularly abundant, infectious, and/or infected tend to contribute disproportionately to symbiont (parasite or mutualist) maintenance in multi-host systems. Therefore, in a facultative multi-host system where two host species had high densities, high symbiont infestation intensities, and high infestation prevalence, we expected interspecific transmission rates to be high. Instead, we found that interspecific symbiont transmission rates to caged sentinel hosts were an order of magnitude lower than intraspecific transmission rates in the wild. Using laboratory experiments to decompose transmission rates, we found that opportunities for interspecific transmission were frequent, where interspecific and intraspecific contact rate functions were statistically indistinguishable. But most interspecific contacts did not lead to transmission events due to a previously unrecognized transmission barrier: strong host preferences. During laboratory choice experiments, the symbiont preferred staying on or dispersing to its current host species, even though the oligochaete symbiont is a globally distributed host generalist that can survive and reproduce on many snail species. These surprising results suggest that when managing symbiont transmission, identifying key host species is still important, but it may be equally important to identify and manage transmission barriers that keep potential superspreader host species in check.</p>
Host preference of a tree-killing bark beetle across a geographic boundary separating host species
<p><span>The life cycles of bark beetles are intimately linked to their host species. Therefore, bark beetle species are expected to show traits that vary among different host species and across geographic ranges. The taxonomic proximity of host tree species can also influence host selection. <em>Abies</em> species native to Japan are genetically classified into three phylogenetic groups. Their natural distributions are separated by a </span><span>distinct biogeographic boundary in Japan (i.e. the Tsugaru Strait, also referred to as Blakiston's Line)</span><span>. Especially, <em>A. sachalinensis</em> is the only species native to Hokkaido, north of the </span><span>Tsugaru Strait</span><span>.

Delimiting the cryptic diversity and host preferences of Sycophila parasitoid wasps associated with oak galls using phylogenomic data
<p>Cryptic species diversity is a major challenge for the species-rich community of parasitoids attacking oak gall wasps due to a high degree of sexual dimorphism, morphological plasticity, small size, and poorly known biology. As such, we know very little about the number of species present, nor the evolutionary forces responsible for generating this diversity. One hypothesis is that trait diversity in the gall wasps, including the morphology of the galls they induce, has evolved in response to selection imposed by the parasitoid community, with reciprocal selection driving diversification of the parasitoids. Using a rare, continental-scale data set of <em>Sycophila</em> parasitoid wasps reared from 44 species of cynipid galls from 18 species of oak across the US, we combined mitochondrial DNA barcodes, Ultraconserved Elements (UCEs), morphological, and natural history data to delimit putative species. Using these results, we generate the first large-scale assessment of ecological specialization and host association in this species-rich group, with implications for evolutionary ecology and biocontrol. We find most <em>Sycophila</em> target specific subsets of available cynipid host galls with similar morphologies, and generally attack larger galls. Our results suggest that parasitoid wasps such as <em>Sycophila</em> have adaptations allowing them to exploit particular host trait combinations, while hosts with contrasting traits are resistant to attack. These findings support the tritrophic niche concept for the structuring of plant-herbivore-parasitoid communities.</p>

Pervasive effects of Wolbachia on host temperature preference
<p>Heritable symbionts can modify a range of ecologically important host traits, including behavior. About half of all insect species are infected with maternally transmitted <i>Wolbachia</i>, a bacterial endosymbiont known to alter host reproduction, nutrient acquisition, and virus susceptibility. Here, we broadly test the hypothesis that <i>Wolbachia</i> modify host behavior by assessing the effects of eight different <i>Wolbachia</i> strains on the temperature preference of six <i>Drosophila melanogaster</i>-subgroup species. Four of the seven host genotypes infected with A-group <i>Wolbachia</i> strains (<i>w</i>Ri<i> </i>in <i>D. simulans</i>, <i>w</i>Ha in <i>D. simulans</i>, <i>w</i>Sh in <i>D. sechellia</i>, and<i> w</i>Tei in <i>D. teissieri</i>) prefer significantly cooler temperatures relative to uninfected genotypes. Contrastingly, when infected with divergent B-group <i>w</i>Mau, <i>D. mauritiana</i> prefer a warmer temperature. For most strains, changes to host temperature preference do not alter <i>Wolbachia</i> titer. However, males infected with <i>w</i>Sh and <i>w</i>Tei experience an increase in titer when shifted to a cooler temperature for 24 hours, suggesting that <i>Wolbachia</i>-induced changes to host behavior may promote bacterial replication and influence <i>Wolbachia</i> transmission rates. Modifications to host temperature preference likely influence host thermoregulation, and understanding the fitness consequences of these effects is crucial for predicting evolutionary outcomes of host-symbiont interactions, including how <i>Wolbachia</i> spread to become common.</p>
