Summary International ports are generally considered the most likely points of entry for alien wood‐boring beetles. A better understanding factors affecting their arrival and establishment at surrounding areas is utmost importance to improve efficacy cost‐effectiveness early detection programmes. Our work aimed how port size characteristics landscape port, in terms forest cover composition, influence occurrence From May September 2012, 15 Italian international forests were monitored with...
Abstract We provide an overview of both traditional and innovative control tools for management three Xylosandrus ambrosia beetles (Coleoptera: Curculionidae: Scolytinae), invasive species with a history damage in forests, nurseries, orchards urban areas. compactus , X. crassiusculus germanus are native to Asia, currently established several countries around the globe. Adult females bore galleries into plant xylem inoculating mutualistic fungi that serve as food source developing progeny....
Abstract The use of semiochemical-baited traps for detection, monitoring, and sampling bark beetles woodboring (BBWB) has rapidly increased since the early 2000s. Semiochemical-baited survey are used in generic (broad community level) specific (targeted toward a species or group) surveys to detect nonnative potentially invasive BBWB, monitor established populations damaging native species, as tool natural communities various purposes. Along with expansion use, much research on ways improve...
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...
Microbial symbionts can play critical roles when their host attempts to colonize a new habitat. The lack of symbiont adaptation in fact hinder the invasion process host. This scenario could change if exotic species are able acquire microorganisms from invaded environment. Understanding ecological factors that influence take-up is thus essential clarify mechanisms behind biological invasions. In this study, we tested whether different forest habitats structure fungal communities associated...
Abstract Longhorn beetles are commonly moved among continents within wood packaging materials used in trades. Visual inspections carried out at points of entry often fail to detect exotic longhorn as infested may have little or no sign colonization. Black-colored traps baited with pheromones and host volatiles thus improve chances detection. Here we tested whether existing surveillance protocols for can be further improved using trap colors different than black. Baited eight (i.e., grey,...
Beetles are commonly moved among continents with international trade. Baited traps set up in and around entry points used to increase chances of early-detection incoming species complement visual inspections. A still underestimated benefit this surveillance approach is the high number diversity collected bycatch species. In study, we exploited a multiyear program carried out baited at five Spanish ports their surrounding natural areas investigate i) importance identifying more promptly...
Ambrosia beetles are fungal-growing insects excavating galleries deep inside the wood. Their success as invaders increased scientific interest towards them. However, most studies on their microbiota targeted fungal associates whereas role of bacterial is understudied. To explore abundant microbial associates, we isolated bacteria from active two widespread ambrosia beetles, Xylosandrus crassiusculus and X. germanus. These isolates were classified within Erwiniaceae family through a...
Abstract The genus Agrilus is one of the most diverse insect genera worldwide. larval feeding activity causes extensive damage in both forests and orchards. In addition, more than 30 species have been introduced outside their native range so far, including emerald ash borer planipennis Fairmaire. Thus, availability efficient trapping protocols for early detection at entry points utmost importance. this study we tested whether developed surveillance A. North America were also effective other...
Non-native bark and ambrosia beetles represent a threat to forests worldwide. Their invasion patterns are, however, still unclear. Here we investigated first, if the spread of non-native is gradual or discontinuous process; second, which are main correlates their community structure; third, whether those correspond native species. We used data on species distribution scolytines in continental 48 USA states. These were analyzed through beta-diversity index, partitioned into richness...
Abstract Ambrosia beetles exhibit broad host ranges but a narrow preference based on the condition of host. Tissues infected by pathogens or containing ethanol can facilitate attacks ambrosia beetles, although it still remains unclear how these factors interact. The present study aimed to examine (i) chestnut logs with fungal pathogen Cryphonectria parasitica and treated (i.e. baited lure, soaked in untreated) (ii) hornbeam different concentrations (3–12.5%) affect selection colonization...
Traps baited with attractive lures are increasingly used at entry-points and surrounding natural areas to intercept exotic wood-boring beetles accidentally introduced via international trade. Several trapping variables can affect the efficacy of this activity, including trap color. In study, we tested whether species richness abundance jewel (Buprestidae), bark ambrosia (Scolytinae), their common predators (i.e., checkered beetles, Cleridae) be modified using colors different those currently...
Abstract Ethanol emitted by stressed trees is an olfactory cue used ambrosia beetles (Coleoptera; Curculionidae; Scolytinae) to locate susceptible hosts colonize. In addition, ethanol enhances the growth of beetle fungal symbionts, improving colonization. Whether host selection and colonization are affected also amount produced tree species unclear. To investigate these mechanisms, we induced attacks in bolts eight coring filling them with either 5% or 90% solutions water. For each...
The geographical exchange of non-native species can be highly asymmetrical, with some world regions donating or receiving more than others. Several hypotheses have been proposed to explain such asymmetries, including differences in propagule pressure, source (invader) pools, environmental features recipient regions, biological traits invaders. We quantified spatiotemporal patterns the insects between Europe, North America, and Australasia, then tested possible explanations for these based on...
The genus Agrilus includes two species, A. planipennis and anxius , that are of particular phytosanitary concern regulated by the European Union legislation. This implies agencies all EU countries obliged to establish specific surveillance programmes verify absence these species from their territory. These activities commonly consist use green-colored traps, which however attractive not only for but also a wide range other species. For this reason, much time expertise is required sort...
