Data from: Multiple refugia from penultimate glaciations in East Asia demonstrated by phylogeography and ecological modelling of an insect pest

Wei Song, Li-Jun Cao, Bing-Yan Li, Ya-Jun Gong, Ary A. Hoffmann & Shu-Jun Wei
Background: Refugial populations in Quaternary glaciations are critical to understanding the evolutionary history and climatic interactions of many extant species. Compared with the well-studied areas of Europe and Northern America, refugia of species in eastern Asia remain largely unknown. Here, we investigated the phylogeographic history of a globally important insect pest, the oriental fruit moth Grapholita molesta, in its native range of China. Results: Genetic structure analyses unveiled three distinct groups and a set of...

Local climate adaptation and gene flow in the native range of two co-occurring fruit moths with contrasting invasiveness

Shu-Jun Wei & Li-Jun Cao
Invasive species pose increasing threats to global biodiversity and ecosystems. While previous studies have characterized successful invaders from ecological traits, characteristics related to evolutionary processes have rarely been investigated. Here we compared gene flow and local adaptation using demographic analyses and outlier tests in two co-occurring moth pests across their common native range of China, one of which (the peach fruit moth, Carposina sasakii) has maintained its native distribution, while the other (the oriental fruit...

Data from: Low genetic diversity but strong population structure reflects multiple introductions of western flower thrips (Thysanoptera: Thripidae) into China followed by human-mediated spread

Li-Jun Cao, Ze-Hua Wang, Ya-Jun Gong, Liang Zhu, Ary Anthony Hoffmann & Shu-Jun Wei
Historical invasion scenarios based on observational records are usually incomplete and biased, but these can be supplemented by population genetic data. The western flower thrips (WFT), Frankliniella occidentalis, invaded China in the last 13 years and has rapidly become one of the most serious pests in the country. To assess whether this invasion involved a single event or multiple events, we examined patterns of genetic diversity and population structure of WFT across 12 Chinese populations...

Data from: Population genetic structure and approximate Bayesian computation analyses reveal the southern origin and northward dispersal of the oriental fruit moth Grapholita molesta (Lepidoptera: Tortricidae) in its native range

Shu-Jun Wei, Bao-Cai Shi, Fan Zhang, Ya-Jun Gong, Li-Jun Cao, Xiao-Jun Guo, Yuan-Min Wang & Xue-Xin Chen
The oriental fruit moth (OFM) Grapholita molesta is one of the most destructive orchard pests. Assumed to be native to China, the moth is now distributed throughout the world. However, the evolutionary history of this moth in its native range remains unknown. In this study, we explored the population genetic structure, dispersal routes and demographic history of the OFM in China and South Korea based on mitochondrial genes and microsatellite loci. The Mantel test indicated...

Data from: A global meta-analyses of the response of multi-taxa diversity to grazing intensity in grasslands

Chao Wang & Yujia Tang
Livestock grazing is an important component and driver of biodiversity in grassland ecosystems. While numerous studies and a few meta-analyses had been conducted on the response of single taxon diversity to grazing in grasslands, a synthesis of how multi-taxa diversity is affected has been largely missing, especially reflecting its changes along a grazing intensity gradient. We performed a comprehensive meta-analyses of 116 published studies on the species richness (SR) and Shannon-Wiener index (H’) of plants,...

Rapid and strong population genetic differentiation and genomic signatures of climatic adaptation in an invasive mealybug

Shu-Jun Wei, Ling Ma, Li-Jun Cao, Ary A. Hoffmann, Ya-Jun Gong, Jin-Cui Chen, Hong-Song Chen, Xu-Bo Wang & Zhong-Shi Zhou
Aim: A growing number of studies suggest that adaptation of invasive species play key roles in their successful establishment in novel environments. However, adaptation of invasive species to climatic conditions remains poorly characterized. This study aimed to understand the population genetic structure produced by the cotton mealybug Phenacoccus solenopsis invasion and to identify preliminary signals of selection during its range expansion. Location: China. Methods: We examined genetic structure of 11 population across China using SNPs,...

Data from: Independently evolved and gene flow‐accelerated pesticide resistance in two‐spotted spider mites

Pan Shi, Li-Jun Cao, Ya-Jun Gong, Ling Ma, Wei Song, Jin-Cui Chen, Ary Hoffmann & Shu-Jun Wei
Pest species are often able to develop resistance to pesticides used to control them, depending on how rapidly resistance can emerge within a population or spread from another resistant population. We examined the evolution of bifenazate resistance in China in the two‐spotted spider mite (TSSM) Tetranychus uticae Koch (Acari: Tetranychidae), one of the most resistant arthropods, by using bioassays, detection of mutations in the target cytb gene, and population genetic structure analysis using microsatellite markers....

Data from: Variable resistance to spinetoram in populations of Thrips palmi across a small area unconnected to genetic similarity

Shu-Jun Wei & Pan Shi
The melon thrips, Thrips palmi, is an increasingly important pest of vegetables in northern China. Some populations have developed resistance in the field to the insecticide spinetoram. Understanding the origin and dispersal of insecticide-resistant populations can shed light on resistance management strategies. In this study, we tested susceptibility of seven greenhouse populations of T. palmi to spinetoram collected from a small area of about 300 km2 in Shandong province, and examined population genetic structure across...

Data from: Patterns of genetic variation among geographic and host-plant associated populations of the peach fruit moth Carposina sasakii (Lepidoptera: Carposinidae)

You-Zhu Wang, Bing-Yan Li, Ary Anthony Hoffmann, Li-Jun Cao, Ya-Jun Gong, Jia-Ying Zhu & Shu-Jun Wei
Background: Populations of herbivorous insects may become genetically differentiated because of local adaptation to different hosts and climates as well as historical processes, and further genetic divergence may occur following the development of reproductive isolation among populations. Here we investigate the population genetic structure of the orchard pest peach fruit moth (PFM) Carposina sasakii (Lepidoptera: Carposinidae) in China, which shows distinct biological differences when characterized from different host plants. Genetic diversity and genetic structure were...

Data from: Responses of plant phenology to nitrogen addition: a meta-analysis

Chao Wang & Yujia Tang
Phenology is one of the most sensitive plant processes in response to global change. Anthropogenic activities have considerably increased nitrogen (N) deposition, which significantly affects plant phenology. Although numerous individual studies have been conducted, a comprehensive understanding of how plant phenology responds to external N inputs remains elusive. We therefore conducted a meta-analysis of 117 species responses to N addition to examine effects on phenology in terrestrial ecosystems, and we assessed variations in their responses...

Data from: Varying the spatial arrangement of synthetic herbivore-induced plant volatiles and companion plants to improve conservation biological control

Coline Jaworski, Da Xiao, Qingxuan Xu, Ricardo Ramirez-Romero, Xiaojun Guo, Su Wang & Nicolas Desneux
1.Conservation biological control aims to control pests by promoting wild populations of natural enemies. One challenge is to attract and retain efficient natural enemies in crop fields, which often are a suboptimal environment. Towards this goal, the attract-and-reward strategy relies on combining attractive synthetically produced herbivore-induced plant volatiles (HIPVs) with companion plants (non-crop plants which provide alternative resources to the targeted natural enemies). Although severely overlooked, the spatial arrangement of HIPV dispensers and rewards inside...

Migration trajectories of the diamondback moth Plutella xylostella in China inferred from population genomic variation

Ming‐Zhu Chen, Li‐Jun Cao, Bing‐Yan Li, Jin‐Cui Chen, Ya‐Jun Gong, Ary Anthony Hoffmann & Shu‐Jun Wei
BACKGROUND: The diamondback moth (DBM), Plutella xylostella (Lepidoptera: Plutellidae), is a notorious pest of cruciferous plants. In temperate areas, annual populations of DBM originate from adult migrants. However, the source populations and migration trajectories of immigrants remain unclear. Here, we investigated migration trajectories of DBM in China with genome-wide single nucleotide polymorphisms (SNPs) genotyped using double-digest RAD (ddRAD) sequencing. We first analyzed patterns of spatial and temporal genetic structure among southern source and northern recipient...

Population genomic signatures of the oriental fruit moth related to the Pleistocene climates

Shu-Jun Wei, Li-Jun Cao, Wei Song & Jin-Cui Chen
The Quaternary climatic oscillations are expected to have had strong impacts on the evolution of species. Although legacies of the Quaternary climates on population processes have been widely identified in diverse groups of species, adaptive genetic changes shaped during the Quaternary have been harder to decipher. Here, we assembled a chromosome-level genome of the oriental fruit moth and compared genomic variation among refugial and colonized populations of this species that diverged in the Pleistocene. High...

Low levels of genetic differentiation with isolation by geography and environment in populations of Drosophila melanogaster from across China

Shu-Jun Wei & Lei Yue
The fruit fly Drosophila melanogaster is a model species in evolutionary studies. However, the population processes of this species in East Asia are poorly studied, even though this area was one of the first regions colonized outside of its native distribution range. Here we examined the population genetic structure of D. melanogaster across China. There were 14 mitochondrial haplotypes with ten unique ones out of 23 known from around the globe. Pairwise FST values estimated...

A global meta-analysis of the impacts of tree plantations on biodiversity
