“…), broadleaf forests surrounding ports represent suitable habitat for their establishment. These areas have been recognized as high‐risk sites in previous studies as the wood‐boring beetles arriving at points of entry can disperse to neighbouring areas exploiting their ability to fly and find suitable hosts and habitats (Bashford ; Rabaglia et al . ).…”

“…), our results show that alien wood‐boring beetles can be present even in landscapes with very low amounts of forest area. Previous studies have suggested that urban areas, which are usually characterized by a wide range of native and alien tree species in parks, gardens and along streets, may provide adequate tree hosts for invaders that would not otherwise become successfully established (Bashford ; Koch et al . ).…”

“…The role of plantings in the landscape surrounding high‐risk sites is, however, still largely under‐investigated (Reed & Muzika ). The movement of alien insects from the port to the surrounding areas is almost inevitable; therefore, these areas are recognized as a crucial point in determining the success or the failure of the invasion process (Bashford ; Rabaglia et al . ).…”

Summary1. International ports are generally considered the most likely points of entry for alien woodboring beetles. A better understanding of the factors affecting their arrival and establishment at ports and their surrounding areas is of utmost importance to improve the efficacy and the cost-effectiveness of early detection programmes. Our work aimed at understanding how port size and the characteristics of the landscape surrounding the port, in terms of forest cover and forest composition, influence the occurrence of alien wood-boring beetles. 2. From May to September 2012, 15 Italian international ports and the surrounding forests were monitored with multi-funnel traps baited with a multi-lure blend (a-pinene, ethanol, ipsdienol, ipsenol, methyl-butenol), three in each port and three in forests located 3-5 km away from the port. We identified both alien and native Scolytinae, Cerambycidae and Buprestidae beetles. 3. Fourteen alien species, among which four are new to Italy, were trapped. Alien species richness was positively related to the amount of imported commodities at the port scale. Broadleaf forests surrounding ports received larger number of alien species than conifer forests. By contrast, total forest cover in the landscape surrounding ports was positively related to the occurrence of native but not alien species. The alien and native species richness was higher in the surrounding forests than in the ports. 4. Synthesis and applications. The simultaneous use of traps in ports with large volume of imported commodities and in their surrounding broadleaf forests can strongly increase the probability of alien wood-boring beetle interceptions. The identification of sites where the arrival and establishment of alien species is more probable, combined with an efficient trapping protocol, can substantially improve the efficacy of early detection. Similar approaches may be used in other countries as early warning systems to implement timely measures to eradicate or contain alien invasions at the European scale.

“…Many post-border forestry pest surveillance programs have been piloted in Eastern Australia involving port-environ surveillance, urban tree monitoring and targeted trapping [2,3]. Expansion of Forests 2019, 10,198 2 of 17 these activities into a nationally coordinated program, targeting high-risk sites and priority pests, will maximise the chance of early detection and possible eradication, thereby reducing the likelihood of exotic pests becoming established in Australia's forests [1,4,5].…”

Effective and efficient systems for surveillance, eradication, containment and management of biosecurity threats require methods to predict the establishment, population growth and spread of organisms that pose a potential biosecurity risk. To support Victorian forest biosecurity operations, Agriculture Victoria has developed a landscape-scale, spatially explicit, spatio-temporal population growth and dispersal model of a generic pest pine beetle. The model can be used to simulate the incursion of a forestry pest from a nominated location(s), such as an importation business site (approved arrangement, AA), into the surrounding environment. The model provides both illustrative and quantitative data on population dynamics and spread of a forestry pest species. Flexibility built into the model design enables a range of spatial extents to be modelled, from user-defined study areas to the Victoria-wide area. The spatial resolution of the model (size of grid cells) can be altered from 100 m to greater than 1 km. The model allows core parameters to be altered by the user, enabling the spread of a variety of windborne insect species and pathogens to be investigated. We verified the model and its parameters by simulating and comparing the outputs with the 1999/2000 Melbourne incursion, but no establishment of a forestry pest beetle was believed to be Monochamus alternatus Hope (Coleoptera: Cerambycidae). The model accurately predicts the distance and direction of the historic incursion, and the subsequent failure to establish is due to low overall population density of the pest species.

Exploiting trap color to improve surveys of longhorn beetles

et al. 2020

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 beetles as infested materials may have little or no sign of colonization. Black-colored traps baited with pheromones and host volatiles are thus used to improve chances of detection. Here we tested whether existing surveillance protocols for longhorn beetles can be further improved using trap colors different than black. Baited traps of eight different colors (i.e., grey, yellow, green, red, blue, brown, purple and black) were deployed in a randomized complete block design at 16 sites in northern Italy in 2019. A total of 6,001 individuals from 56 longhorn beetle species were trapped. In general, yellow and blue traps caught a significantly higher number of longhorn beetle species than black traps. In addition, trap color significantly affected species richness and abundance at the subfamily and species level, with mixed response mostly linked to the habit of visiting flowers for food. Flower-visiting longhorn beetles mainly exhibited clear preference for flower-related colors, i.e., yellow, green and blue, whereas non-flower-visiting species were more attracted by dark and long-wavelength-dominated colors, like red and brown. Our results clearly indicate that generic surveillance programs should not rely exclusively on black traps and that the use of more trap colors can strongly improve the chance of detecting native and exotic longhorn beetles potentially moved with trades.
