No evidence of bacterial symbionts influencing host specificity in Aphis gossypii Glover (Hemiptera: Aphididae)
<p class="MDPI17abstract"><span>The cotton-melon aphid, <em>Aphis gossypii</em> Glover, is a polyphagous insect pest with many host-specialized biotypes, such as Cucurbitaceae- and Malvaceae-specialized (CU and MA) biotype. Bacterial symbionts were reported to determine host range in some aphids. Whether this is the case in<em> A. gossypii</em> remains unknown. Here, we tested host specificity of CU and MA biotype and compared host specificity between wingless and winged morph within the same biotype, and analyzed the composition of bacterial symbionts. The reproduction of CU and MA biotype reduced by 66.67% and 82.79% </span><span>res</span><span>pectively on non-native hosts, compared with that on native hosts. The composition of bacterial symbionts was not significantly different between CU and MA biotype, with <em>Buchnera</em> abundance >95% in both biotypes. While, winged morph produced significantly more nymphs than wingless morph on non-native hosts, and<a name="OLE_LINK1"></a> <em>Buchnera</em> abundance in winged morph was only about 10% of that in wingless morph. There seemed to be a relationship between <em>Buchnera</em> abundance and host specificity. We regulated <em>Buchnera</em> abundance by temperature and antibiotics, but did not find that low <em>Buchnera</em> abundance resulted in high reproduction on non-native hosts. We conclude that host specificity of <em>A. gossypii</em> is not controlled by specific bacterial symbionts or by <em>Buchnera</em> abundance.</span></p>

APHIS Asian Longhorned Tick Observation Data 2010-2020
<p>NVSL tick observation data from APHIS (NVSL, 2020). NVSL is a national dataset of passive surveillance observations of tick species that impact animal health. NVSL samples are submitted when a suspected ALT is observed by regulatory field veterinarians, state and university diagnostic laboratories, and Food Safety and Inspection Service veterinarians. Data was collected from host animals, including humans, and environmental sources such as tick drags, carbon dioxide (CO2) traps, and animal inspections. Ticks identified on animals that were recently imported into the U.S. are not included. The first observation of ALT occurred in August 2010 and data is current as of November 2020. Data includes tick species, date, state, source (environment vs host) and number of ALT by life stage.</p>

Data from: Genetic diversity of melon aphids Aphis gossypii associated with landscape features
Despite increasing evidence that landscape features strongly influence the abundance and dispersal of insect populations, landscape composition has seldom been explicitly linked to genetic structure. We conducted a genetic study of the melon aphid, Aphis gossypii, in two counties of Beijing, China during spring migration using samples from watermelon. We performed aphid genetic analysis using restriction-site-associated DNA-sequencing (2b-RAD) and investigated the relationship between land cover and the genetic diversity. The percentage area of land cover (cropland, vegetable, orchard, grassland, woodland) was quantified in each particular scale (ranging from 0.5 km to 3 km) and was used as a predictor variable in our generalized linear models. We found a moderate level of genetic differentiation among 9 sampled populations. Geographic distance and genetic distance were not significantly associated, indicating that geographic location was not a barrier to migration. These 9 populations could be clustered depending on their level of genetic diversity (high and low). The genetic diversity (Shannon's information index) was positively correlated with grassland at the spatial scales of 1 and 2 km and negatively with orchard and vegetable at 0.5 and 1 km. Genetic diversity was best predicted by the grassland + orchard + vegetable model at a spatial scale of 1 km. Based on the method of relative weights, orchard land had the greatest relative importance, followed by grassland and vegetable land, in that order. This study contributes to our understanding of the genetic variation of aphids in agricultural landscapes.
Data from: Climate effects on life cycle variation and population genetic architecture of the black bean aphid, Aphis fabae
Aphid species commonly have different reproductive modes ranging from cyclical to obligate parthenogenesis. The distribution of life cycle variation in aphids is generally determined by ecological forces, mainly climate, because only sexually produced diapausing eggs can survive harsh winters. Aphids are thus interesting models to investigate intrinsic and environmental factors shaping the competition among sexual and asexual lineages. We conducted a Europe-wide sampling of black bean aphids, Aphis fabae, and combined population genetic analyses based on microsatellite data with an experimental determination of life cycle strategies. Aphids were collected from broad beans (Vicia faba) as well as some Chenopodiaceae, but we detected no genetic differentiation between aphids from different host plants. Consistent with model predictions, life cycle variation was related to climate, with aphids from areas with cold winters investing more in sexual reproduction than aphids from areas with mild winters. Accordingly, only populations from mild areas exhibited a clear genetic signature of clonal reproduction. These differences arise despite substantial gene flow over large distances, which was evident from a very low geographic population structure and a lack of isolation-by-distance among 18 sites across distances of more than 1000 kilometres. There was virtually no genetic differentiation between aphids with different reproductive modes, suggesting that new asexual lineages are formed continuously. Indeed, a surprising number of A. fabae genotypes even from colder climates produced some parthenogenetic offspring under simulated winter conditions. From this we predict that a shift to predominantly asexual reproduction could take place rapidly in under climate warming.
Data from: Implementing an evolutionary framework for understanding genetic relationships of phenotypically defined insect biotypes in the invasive soybean aphid (Aphis glycines)
Adaptive evolution of pest insects in response to the introduction of resistant cultivars is well documented and commonly results in virulent (i.e. capable of feeding upon resistant cultivars) insect populations being labeled as distinct biotypes. Phenotypically defined, biotypes frequently remain evolutionarily indistinct, resulting in ineffective application of virulence control measures and shorter durability of resistant cultivars. Here we utilize an evolutionary framework to discern the genetic relationship between biotypes of the soybean aphid (Aphis glycines, Matsumura). The soybean aphid is invasive in North America, and is among the most destructive pests of commercial soybean on the continent. Attempts to breed host-plant resistant soybean have been hampered by the emergence of virulent aphid biotypes that are unaffected by the plant's resistance mechanism(s). Comparative population genetic analysis of virulent and avirulent (i.e. unable to feed on resistant cultivars) biotypes found populations to be genetically indistinguishable across biotype and geographic distance, with high rates of inter-population immigration and admixture. The lack of genetic distinction between biotypes coupled with elevated genotypic diversity within all populations suggested virulence has a non-genetic based or includes a gene complex that is widely distributed throughout soybean aphid populations, which undergo regular dispersal and unimpeded sexual recombination.
