“…Recently, Rassati et al (2020) reported that infection of Castanea sativa (Miller) (Fagaceae) logs by chestnut blight (Cryphonectria parasitica (Murrill) Barr) (Cryphonectriaceae) influences host-selection behaviour in the xyleborine Anisandrus dispar F., but not in X. germanus. The combination of root infection by Phytophthora cinnamomi Rands (Peronosporaceae) and flood stress also influences the host-selection behaviour of X. crassiusculus and X. germanus (Addesso et al 2018;Brown et al 2019). Future work should focus on understanding the extent to which beetles are attracted to volatiles that may arise from the interaction of pathogens with their woody hosts.…”

Exotic ambrosia beetles (Curculionidae: Scolytinae) in the tribe Xyleborini include destructive pests of trees growing in horticultural cropping systems. Three species are especially problematic: Xylosandrus compactus (Eichhoff), Xylosandrus crassiusculus (Motschulsky), and Xylosandrus germanus (Blandford). Due to similarities in their host tree interactions, this mini-review focuses on these three species with the goal of describing their host-selection behaviour, characterising associated semiochemicals, and assessing how these interactions relate to their management. All three of these Xylosandrus spp. attack a broad range of trees and shrubs. Physiologically stressed trees are preferentially attacked by X. crassiusculus and X. germanus, but the influence of stress on host selection by X. compactus is less clear. Ethanol is emitted from weakened trees in response to a variety of stressors, and it represents an important attractant for all three species. Other host-derived compounds tested are inconsistent or inactive. Verbenone inhibits attraction to ethanol, but the effect is inconsistent and does not prevent attacks. Integrating repellents and attractants into a push–pull management strategy has been ineffective for reducing attacks but could be optimised further. Overall, maintaining host vigour and minimising stress-induced ethanol are keys for managing these insects, particularly X. crassiusculus and X. germanus.

“…Plant growth promoting rhizobacteria (PGPR), including those previously mentioned, also through the addiction of organic amendments, can stimulate plant yield and protect from diseases through several mechanisms [73]. On the other hand, many fungi also show effectiveness in disease management, mostly belonging to the genus Clonostachys, Gliocladium, Ulocladium, Cladosporium, and Trichoderma [68,74]. In particular, Trichoderma spp.…”

Ornamental plant production constitutes an important sector of the horticultural industry worldwide and fungal infections, that dramatically affect the aesthetic quality of plants, can cause serious economic and crop losses. The need to reduce the use of pesticides for controlling fungal outbreaks requires the development of new sustainable strategies for pathogen control. In particular, early and accurate large-scale detection of occurring symptoms is critical to face the ambitious challenge of an effective, energy-saving, and precise disease management. Here, the new trends in digital-based detection and available tools to treat fungal infections are presented in comparison with conventional practices. Recent advances in molecular biology tools, spectroscopic and imaging technologies and fungal risk models based on microclimate trends are examined. The revised spectroscopic and imaging technologies were tested through a case study on rose plants showing important fungal diseases (i.e., spot spectroscopy, hyperspectral, multispectral, and thermal imaging, fluorescence sensors). The final aim was the examination of conventional practices and current e-tools to gain the early detection of plant diseases, the identification of timing and spacing for their proper management, reduction in crop losses through environmentally friendly and sustainable production systems. Moreover, future perspectives for enhancing the integration of all these approaches are discussed.

“…Overall, ethanol-treated bolts, trap logs, and trap trees of selected species can be used to attract and trap Xylosandrus species selectively, i.e., with low non-target catches (Mayfield et al 2013;Reding et al 2017;Addesso et al 2019;Rassati et al 2020;Reding and Ranger 2020). Manipulation of tree attractiveness to beetles with the aim to develop monitoring strategies or to reduce colonization of the cultivated target crop could emerge as an innovative behavior-based management strategy.…”

“…Another semiochemical-based strategy, more recently evaluated for Xylosandrus ambrosia beetles, combines ethanolbaited traps (or trap trees) placed at a distance from the vulnerable host plants and repellents appropriately placed on or in close proximity to the protected crop (Ranger et al 2013b;Addesso et al 2019;Werle et al 2019). This management strategy, known as push-pull, manipulates the behavior of insects by combining the two forces: (1) a repellent to 'push' them away from the cultivated host and (2) an attractant to 'pull' them into a trap crop or artificial trap (Cook et al 2007).…”

However, efforts to use ethanol lures or trap trees (i.e., ethanol-injected or flood-stressed plants) as a 'pull' attractant and synthetic repellents as a 'push' component has had inconsistent results (Ranger et al 2013b;Addesso et al 2019;Werle et al 2019;Rivera et al 2020).…”

We provide an overview of both traditional and innovative control tools for management of three Xylosandrus ambrosia beetles (Coleoptera: Curculionidae: Scolytinae), invasive species with a history of damage in forests, nurseries, orchards and urban areas. Xylosandrus compactus, X. crassiusculus and X. germanus are native to Asia, and currently established in several countries around the globe. Adult females bore galleries into the plant xylem inoculating mutualistic ambrosia fungi that serve as food source for the developing progeny. Tunneling activity results in chewed wood extrusion from entry holes, sap outflow, foliage wilting followed by canopy dieback, and branch and trunk necrosis. Maintaining plant health by reducing physiological stress is the first recommendation for long-term control. Baited traps, ethanol-treated bolts, trap logs and trap trees of selected species can be used to monitor Xylosandrus species. Conventional pest control methods are mostly ineffective against Xylosandrus beetles because of the pests’ broad host range and rapid spread. Due to challenges with conventional control, more innovative control approaches are being tested, such as the optimization of the push–pull strategy based on specific attractant and repellent combinations, or the use of insecticide-treated netting. Biological control based on the release of entomopathogenic and mycoparasitic fungi, as well as the use of antagonistic bacteria, has yielded promising results. However, these technologies still require validation in real field conditions. Overall, we suggest that management efforts should primarily focus on reducing plant stress and potentially be combined with a multi-faceted approach for controlling Xylosandrus damage.
