Data from: Geosmithia associated with bark beetles and woodborers in the western USA: taxonomic diversity and vector specificity
Fungi in the genus Geosmithia (Ascomycota: Hypocreales) are frequent associates of bark beetles and woodborers that colonize hardwood and coniferous trees. One species, Geosmithia morbida, is an economically damaging invasive species. The authors surveyed the Geosmithia species of California and Colorado, USA, to (i) provide baseline data on taxonomy of Geosmithia and beetle vector specificity across the western USA; (ii) investigate the subcortical beetle fauna for alternative vectors of the invasive G. morbida; and (iii) interpret the community composition of this region within the emerging global biogeography of Geosmithia. Geosmithia was detected in 87% of 126 beetle samples obtained from 39 plant species. Twenty-nine species of Geosmithia were distinguished, of which 13 may be new species. Bark beetles from hardwoods, Cupressus, and Sequoia appear to be regular vectors, with Geosmithia present in all beetle gallery systems examined. Other subcortical insects appear to vector Geosmithia at lower frequencies. Overall, most Geosmithia have a distinct level of vector specificity (mostly high, sometimes low) enabling their separation to generalists and specialists. Plant pathogenic Geosmithia morbida was not found in association with any other beetle besides Pityophthorus juglandis. However, four additional Geosmithia species were found in P. juglandis galleries. When integrated with recent data from other continents, a global pattern of Geosmithia distribution across continents, latitudes, and vectors is emerging: of the 29 Geosmithia species found in the western USA, 12 have not been reported outside of the USA. The most frequently encountered species with the widest global distribution also had the broadest range of beetle vectors. Several Geosmithia spp. with very narrow vector ranges in Europe exhibited the similar degree of specialization in the USA. Such strong canalization in association could reflect an ancient origin of each individual association, or a recent origin and a subsequent diversification in North America.

Data from: Effective population size of Culex quinquefasciatus under insecticide-based vector management and following Hurricane Harvey in Harris County, Texas
<div> <em>Culex quinquefasciatus</em> is mosquito species of significant public health importance due to its ability to transmit multiple pathogens that can cause mosquito-borne diseases, such as West Nile fever and St. Louis encephalitis. In Harris County, Texas, <em>Cx. quinquefasciatus</em> is a common vector species and is subjected to insecticide-based management by the Harris County Public Health Department. However, insecticide resistance in mosquitoes has increased rapidly worldwide and raises concerns about maintaining the effectiveness of vector control approaches. This concern is highly relevant in Texas, with its humid subtropical climate along the Gulf Coast that provides suitable habitat for <em>Cx. quinquefasciatus</em> and other mosquito species that are known disease vectors. Therefore, there is an urgent and ongoing need to monitor the effectiveness of current vector control programs. In this study, we evaluated the impact of vector control approaches by estimating the effective population size of <em>Cx. quinquefasciatus</em> in Harris County. We applied Approximate Bayesian Computation to microsatellite data to estimate effective population size. We collected <em>Cx. quinquefasciatus</em> samples from two mosquito control operation areas, 415 and 802, during routine vector monitoring in 2016 and 2017. No county mosquito control operations were applied at area 415 in 2016 and 2017, whereas extensive adulticide spraying operations were in effect at area 802 during the summer of 2016. We collected data for eighteen microsatellite markers for 713 and 723 mosquitoes at eight timepoints from 2016 to 2017 in areas 415 and 802, respectively. We also investigated the impact of Hurricane Harvey's landfall in the Houston area in August of 2017 on <em>Cx. quinquefasciatus</em> population fluctuation. Although we did not detect significant effects of vector control interventions, we found considerable influences of the winter season and a major hurricane on the effective population size of <em>Cx. quinquefasciatus</em>. The fluctuations in effective population size in both areas showed a significant seasonal pattern. Additionally, the significant population expansion following Hurricane Harvey in 2017 supports the necessity for post-hurricane vector-control interventions.</div>

Data for: Phenotypic adaptation to temperature in the mosquito vector, Aedes aegypti
<p><span>Most models exploring the effects of climate change on </span><span>mosquito-borne disease ignore thermal adaptation. However, if local adaptation leads to changes in mosquito thermal responses, 'one size fits all' models could fail to capture current variation between populations and future adaptive responses to changes in temperature. Here we assess phenotypic adaptation to temperature in <em>Aedes aegypti</em>, the primary vector of dengue, Zika, and chikungunya viruses. First, to explore whether there is any difference in existing thermal response of mosquitoes between populations we used a thermal knockdown assay to examine five populations of <em>Ae. aegypti </em>collected from climatically diverse locations in Mexico, together with a longstanding laboratory strain. We identified significant phenotypic variation in thermal tolerance between populations. Next, to explore whether such variation can be generated by differences in temperature we conducted an experimental passage study by establishing six replicate lines from a single field-derived population of <em>Ae. aegypti </em>from Mexico, maintaining half at 27<strong><span class="nounderlines">°</span></strong>C and the other half at 31<strong><span class="nounderlines">°</span></strong>C. After 10 generations we found a significant difference in mosquito performance, with the lines maintained under elevated temperatures showing greater thermal tolerance. Moreover, these differences in thermal tolerance translated to shifts in the thermal performance curves for multiple life history traits, leading to differences in overall fitness. Together, these novel findings provide compelling evidence that <em>Ae. aegypti </em>populations can and do differ in thermal response, suggesting that simplified thermal performance models might be insufficient for predicting the effects of climate on vector-borne disease transmission. </span></p>
Expression analysis of targeted genes Sgt1 (A) and Hsp90 (B) in tomato plants subjected to virus-induced gene silencing using Tobacco rattle virus (TRV) vector.
<p><strong>Figure S1</strong>. Expression analysis of targeted genes Sgt1 (A) and Hsp90 (B) in tomato plants subjected to virus-induced gene silencing using Tobacco rattle virus (TRV) vector. (A) Relative expression levels of Sgt1 analyzed by Reverse Transcription-quantitative Polymerase Chain Reaction (RT-qPCR) in tomato plants infected with TRV vector alone (TRV2), TRV carrying Sgt1 silencing constructs (TRV-Sgt1), and mock-inoculated (Mock). Transcript levels were normalized using tomato genes encoding elongation factor 1-α and SAND as internal references, with Mock as the calibrator. (B) Relative expression levels of Hsp90 analyzed by RT-qPCR in tomato plants infected with TRV2, TRV-Hsp90, and Mock. Gene expression levels were normalized using the same reference genes as in (A). (C) Quantification of the relative accumulation of TRV RNA in plants infected with TRV2 and in silenced plants (TRV-Sgt1 and TRV-Hsp90). The expression levels were normalized using tomato genes for elongation factor 1-α and SAND, with TRV2 as the calibrator. All samples were collected at 19 dpi to anticipate the observed decline. Error bars represent standard errors of five biological replicates, and an asterisk indicates a significant difference, as determined by one-way ANOVA with P < 0.05</p>
