Standardized tools are needed to identify and prioritize the most harmful non-native species (NNS). A plethora of assessment protocols have been developed evaluate current potential impacts species, but consistency among them has received limited attention. To estimate across impact protocols, 89 specialists in biological invasions used 11 screen 57 NNS (2614 assessments). We tested if scoring assessors, quantified as coefficient variation (CV), was dependent on characteristics protocol,...
Xylosandrus compactus and X. crassiusculus are two polyphagous ambrosia beetles originating from Asia invasive in circumtropical regions worldwide. Both species were recently reported Italy further invaded several other European countries the following years. We used MaxEnt algorithm to estimate suitable areas worldwide for both under current climate. also made future projections years 2050 2070 using 11 different General Circulation Models, 4 Representative Concentration Pathways (2.6, 4.5,...
A large proportion of the insects which have invaded new regions and countries are emerging species, being found for first time outside their native range. Being able to detect such species upon arrival at ports entry before they establish in non-native is an urgent challenge. The deployment traps baited with broad-spectrum semiochemical lures ports-of-entry other high-risk sites could be one early detection tool. Rapid progress identification semiochemicals cerambycid beetles during last 15...
Abstract Non-native pests, climate change, and their interactions are likely to alter relationships between trees tree-associated organisms with consequences for forest health. To understand predict such changes, factors structuring communities need be determined. Here, we analysed the data consisting of records insects fungi collected from dormant twigs 155 tree species at 51 botanical gardens or arboreta in 32 countries. Generalized dissimilarity models revealed similar relative importance...
Quarantine measures to prevent insect invasions tend focus on well-known pests but a large proportion of the recent invaders were not known cause significant damage in their native range, or even science before introduction. A novel method is proposed detect new potential woody plants region origin they are introduced continent. Since Asia currently considered be main supplier Europe, sentinel trees planted China during 2007-2011 as an early warning tool identify for additional Asian species...
We compared the recruitment of phytophagous arthropod pests onto exotic conifers introduced in Europe without any congeners with that have native congeners. In 130 years extensive plantation forestry Europe, Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) recruited only 87 species, i.e., 33.9% number associated species its range (257 spp.). Exotic Cupressaceae indigenous also a portion (3.4% to 57.9%) fauna observed their range. both cases, majority were polyphagous, they can feed on...
The international seed trade is considered relatively safe from a phytosanitary point of view and therefore less regulated than in other plants for planting. However, the pests carried by traded seeds are not well known. We assessed insects fungi 58 lots 11 gymnosperm angiosperm tree species North America, Europe, Asia. Insects were detected X-raying molecular methods. fungal community was characterized using high-throughput sequencing (HTS) growing on non-selective agar. About 30% contained...
Abstract Most invasive species established in E urope originate from either A sia or N orth merica, but little is currently known about the potential of natolian P eninsula ( M inor) and/or ear ast to constitute invasion sources. Mediterranean forests are generally fragile ecosystems that can be threatened by organisms coming different regions editerranean B asin, for which historical data difficult gather and phylogeographic patterns still poorly understood most terrestrial organisms. In...
The number of invasive alien pest and pathogen species affecting ecosystem functioning, human health economies has increased dramatically over the last decades. Discoveries pests pathogens previously unknown to science or with host associations yet damaging on novel hosts highlights necessity developing tools predict their appearance in hitherto naïve environments. use sentinel plant systems is a promising tool improve detection before introduction provide valuable information for...
Forests are increasingly threatened worldwide by the establishment of non-native species arriving from other continents with globalization trade and international travels. We compiled comprehensive lists insects associated to woody plants in Europe China compare their invasive patterns between these two regions. By 2019, a total 449 have colonized forest, ornamental fruits trees shrubs whereas only 77 were reported China, likely underestimated number because studies concentrated on...
Abstract In an era marked by rapid global changes, the reinforcement and modernization of plant health surveillance systems have become imperative. Sixty-five scientists present here a research agenda for enhanced modernized to anticipate mitigate disease pest emergence. Our approach integrates wide range scientific fields (from life, social, physical engineering sciences) identifies key knowledge gaps, focusing on anticipation, risk assessment, early detection, multi-actor collaboration....
We analysed the notifications of non‐compliance reported by EPPO for 29 European countries period 1995–2004. Although gaps probably existed some these countries, a total 8889 interceptions non‐indigenous pests were reported, among which insects largely dominant (75.9%) followed nematodes (11.7%). Pests came predominantly from Asia (38.2%) but intra‐European exchanges contributed roughly same proportion (33.2%). The predominant commodities on arrived cut flowers (22.3%), plants planting and...
Among eukaryotes, sexual reproduction is by far the most predominant mode of reproduction. However, some systems maintaining sexuality appear particularly labile and raise intriguing questions on evolutionary routes to asexuality. Thelytokous parthenogenesis a form spontaneous loss leading strong distortion sex ratio towards females resulting from mutation, hybridization or infection bacterial endosymbionts. We investigated whether ecological specialization likely mechanism spread thelytoky...
Ornamental plants represent a major pathway of invasion for alien pests worldwide. Commodity risk analyses are carried out to assess the posed by new trade in commodity, but they restricted our limited knowledge traded plants. We used sentinel nursery technique identify insects attacking woody imported into Europe. established two nurseries China, with five Asian These were monitored years obtain lists that can be expected on these commodities. records compared those obtained from literature...
Abstract 1. Non‐lethal genetic surveys in insects usually extract DNA from a leg or piece of wing. Although preferable to lethal sampling, little is known about the effect leg/wing non‐lethal sampling on fitness‐related traits. 2. Graellsia isabelae (Graells, 1849) European moth protected by Habitats Directive and Bern Convention. Conservation genetics this species should therefore use sampling. 3. The present study aimed (1) quantify effects both hind‐wing tail survivorship reproductive...
Abstract The consumption of edible pine seeds stone by the invasive L eptoglossus occidentalis represents a major concern for producers in M editerranean countries but, to date, little knowledge is available about its feeding process on these seeds. In present study, we tested whether . capable upon mature and also estimated impact that they may induce. Sound were offered bugs under laboratory conditions. Seed content was analyzed via multitechnique approach using stereomicroscope, X ‐rays...
Abstract. Phylogenetic relationships amongst Megastigmus species (Chalcidoidea: Torymidae) associated with conifer seeds were inferred from DNA sequence data. Twenty‐nine of seed chalcids analysed using two different genes, cytochrome b (mitochondrial DNA) and the D2 domain 28S ribosomal DNA. Maximum‐parsimony maximum‐likelihood analyses showed that taxa formed monophyletic groups, one clade comprising all Cupressaceae Taxodiaceae hosts exception Chamaecyparis , other composed Pinaceae....
Abstract Understanding how invasive species establish and spread is vital for developing effective management strategies invaded areas identifying new where the risk of invasion highest. We investigated explanatory power dispersal histories reconstructed based on local‐scale wind data a regional‐scale wind‐dispersed particle trajectory model seed chalcid wasp M egastigmus schimitscheki (Hymenoptera: Torymidae) in France. The was tested by: (1) survival analysis empirical . presence, absence...
