“…ex Laws., in the southwestern United States. Periodic outbreaks of this disturbance agent have caused considerable mortality across the Southwest (Lucht et al 1974, Massey et al 1977. Stevens and Flake (1974) indicated that basal area and numbers of ponderosa pines were reduced up to 50% in some stands during an outbreak in the early 1970s.…”

Overwintered adults of Dendroctonus simplex LeConte emerged in May and June. One generation and two broods were produced in both 1983 and 1984. Females initiated attacks and males arrived within 2 days. One to four pairs of beetles used each entrance hole but each pair constructed a separate egg gallery.Emergence, host attack, and re-emergence occurred between 1030 and 1700 hours NDT and at mean air temperatures above 4°C. Peaks of attack, which reflect flight peaks, occurred at temperatures above 10°C. About 90% of all parents re-emerged from first brood trees and 61% from second brood trees.Only adults overwintered. Freezing temperatures caused complete mortality of immature stages. Thirty-five percent of new brood adults emerged in the fall and re-entered galleries at the base of trees for hibernation. Adult tolerance to cold increased from early fall to mid-winter.

“…Not relevant reports were those that made projections in time and space or that described impacts inferred from observed variables that were not the ones of interest (IUCN, 2020a, 2020b). For instance, some studies, such as Lucht et al (1974) for Dendroctonus adjunctus , reported indications about attack behaviour and emergence of the beetle, but no data regarding the degree of tree damage. Data were extracted only from relevant reports and contained information about: the bark beetle species of interest; its status in the region in which the study was conducted (native, alien or neonative); location of the study; native species impacted; quote that gives proof of the impact magnitude and mechanism; reference; impact mechanism; impact magnitude; confidence score and its justification (if and why the magnitude of impact could have been lower or higher) and further comments.…”

Aim: Anthropogenic environmental modifications such as climate or land-use change are causing species to move on their own beyond their native ranges. As this phenomenon will increase in the near future, it is crucial to determine whether rangeexpanding species, or neonatives, are more or less likely than native and alien species to impact their recipient ecosystems. Here, we compared impact magnitudes of bark beetle species from their native, neonative and alien ranges, simultaneously. Location: Global. Methods:We formulated four general scenarios about the magnitude of environmental impacts in different ranges (native, neonative and alien) based on hypotheses commonly used in invasion biology. We tested these scenarios globally on Dendroctonus bark beetles, asking whether they have the most harmful impacts in their native, neonative or alien ranges. Impacts reported in the literature were assessed with the IUCN Environmental Impact Classification for Alien Taxa (EICAT). Results:We found that bark beetles cause the most harmful impacts in their native ranges, followed by the neonative ranges, while impacts in their alien ranges are the lowest. This indicates that the more dissimilar the environment is from that in the native range, the lower the probability of high-impact magnitudes. Our results align with several non-exclusive hypotheses, e.g. pre-adaptation and habitat filtering, while they do not support others, e.g. enemy release or Darwin's naturalization. The results are also in contrast with previous studies on vertebrates and plants, which found no or mixed differences in impact magnitudes with biogeographic origin.Main conclusions: Our analysis suggests that bark beetles, like other species that are keystone and abundant in their native ranges, have generally lower impacts when introduced to novel environments due to biotic resistance or lack of pre-adaptation.Research and management implications regarding the impacts of neonative and alien populations are also discussed.
