“…Hylurgus ligniperda is monogamous and usually has one generation per year but may have up to three generations per year (CABI 2021a). The ight activity in Chile has been observed to have two peaks that are variables in magnitude, one in the spring and another one in the autumn (Lanfranco 2002;Mausel et al 2007, Ahumada personal observation), while in Uruguay the peak occurs earlier, during the winter, with a shorter peak in the summer (Gómez et al 2017). Captures of this species in Uruguay were found to be signi cantly predicted by temperature anomaly and season, since it was most abundant during unusually warm periods of winter months, while its abundance was not signi cantly related to precipitation during trapping periods (Gómez et al 2020).…”

“…In forest plantations in South America, the detection of established nonnative pests has increased exponentially in recent decades (Corley et The initial stage in developing an effective control strategy for non-native species entails promptly identifying them in recently invaded areas and understanding the biological characteristics they exhibit in the new environmental conditions. Although the occurrence of some of these species of non-native pine bark beetles and ecological characteristics such as the patterns in ight phenology have been studied in some locations (Mausel et al 2007;Gómez et al 2017), the distribution and invasion history of these species within pine plantations of South America remain poorly understood. The aim of this study was to describe the distribution and invasion history of the established bark beetles in pine plantations of southern South America, and to review the available information on their phenology and host range.…”

“…Bright 1992; Beaver 2010; Faccoli et al 2012).Cyrtogenius luteus is a polygynous species and has at least two generations per year. The ight activity in Uruguay and Brazil occurs mostly during early summer(Gómez et al 2017; Flechtman and Atkinson 2018), and the species abundance peaks during periods of high precipitation, while it shows no response to temperature(Gómez et al 2020). The species usually infests stressed or dying Pinus species but is also recorded in other Pinaceae (Larix and Picea)(Wood and Bright 1992).…”

The growth of international trade, coupled with an expansion of large-scale pine plantations in South America during the second half of the 20th century, has signi cantly increased the opportunities for invasion of forest insects. Bark beetles (Coleoptera: Curculionidae, Scolytinae) are a large and diverse group of insects, commonly recognized as one of the most important tree mortality agents in coniferous forests worldwide and an important group among invasive forest species. In this study, we combined data from eld sampling with published records of established non-native pine bark beetles, to describe their distribution and invasion history in pine plantations across southern South America, reviewing the available information on their phenology and host range. We obtained records of established populations of six Eurasian species distributed in two major regions: the southwest region comprises plantations in Chile and the Argentine Patagonia, with four bark beetle species: Hylurgus ligniperda, Orthotomicus laricis, Hylastes ater, and Hylastes linearis; the northeastern zone includes northeastern Argentina, Uruguay, and southern Brazil, includes three bark beetle species: H. ligniperda, Cyrtogenius luteus and O. erosus. The establishment of non-native populations across the study area began in the 1950s, and from the 1980s onwards, there has been an exponential increase in introductions. We predict that several of these species will continue spreading across South America, and that new species will continue arriving.We highlight the importance of international collaboration for early detection and management of nonnative pine bark beetles.

“…The introduction of any non-native plant species in new habitats often results in unexpected pest issues, and predictably this happened in this system as well. Mediterranean pine bark beetles are posing a constant and novel threat to the large plantations of highly susceptible, fast-growing, non-native pine tree species, which are growing in environments with no native pine pests (Sopow et al 2015;Gómez et al 2017) and associated native natural enemies able to provide biological control (Colautti et al 2004).…”

Several European and Mediterranean species of pine bark beetles (Coleoptera: Curculionidae: Scolytinae) have become established in North America and the southern hemisphere, posing a novel threat to planted and naturally-occurring pine forests. Our objectives were to investigate (i) the occurrence and relative abundance of pine bark beetles in these regions, and (ii) the trapping performance of different blends of multispecies lures. In 2016-2017 a network of interception traps was installed in six non-European countries (Argentina, Australia, New Zealand, South Africa, the United States, and Uruguay), and in six European countries (France, Greece, Hungary, Italy, Portugal, and Spain) for comparison. Half of the traps were baited with alpha-pinene and ethanol, and the other half with alpha-pinene, ethanol, and a combination of bark beetle pheromones (ipsdienol, ipsenol, and Z-verbenol). Five Mediterranean scolytine species (Hylurgus ligniperda, Hylastes ater, H. angustatus, Orthotomicus erosus, and O. laricis) were found in non-European countries. Hylurgus ligniperda and Hylastes ater were the most widespread species found in several of the invaded regions, while O. laricis and H. angustatus occurred only in Argentina and South Africa, respectively. Despite large variation among species and countries, most species were trapped with the blend containing bark beetle pheromones, except O. erosus, which was more attracted to alpha-pinene and ethanol alone. This study represents the first step towards the development of an international monitoring protocol based on multi-lure traps for the survey and early-interception of invasive alien bark beetle species.

Bark beetles often feed on dead or dying plant tissues, serving as primary decomposers. However, some bark beetle species kill healthy trees, although at the time of attack, these healthy trees are often experiencing stressful conditions, such as drought or lightning strikes. Populations of tree-killing bark beetles can increase in size to a level where they can overcome the resistance of healthy trees and cause mass destruction of forests resulting in tremendous economic and ecological damage. This chapter introduces the reader to bark beetle natural history, diversity, evolution and management. Natural history is organized by feeding ecology, mating strategies, and intra– and interspecific interactions. Evolution and diversity of bark beetles includes discussion of phylogeny, timing of evolutionary events and an annotated and illustrated list of bark beetle genera important to forest entomologists. Management and control covers efforts to reduce losses to bark beetle destruction of forests and plant products. Finally, we present case studies, including outbreak events, which have resulted in vast economic and ecological loss.
