Bark beetles (Coleoptera: Curculionidae: Scolytinae) are among the most damaging tree pests globally. Rising temperatures, drought, fire, storms, cyclones, and poor forest management cause stress and loss of vigour in trees, and these conditions favour bark beetle outbreaks. While research has been conducted on push–pull strategies to deter bark beetles, using attractive and deterrent semiochemicals, the potential of this strategy to reduce bark beetle populations, particularly in the genera <i>Dendroctonus</i> and <i>Ips</i>, remains uncertain. Here, we conducted a global meta-analysis of 52 research articles to quantify the effects of semiochemical treatments on managing different species of <i>Dendroctonus</i> and <i>Ips</i> for forest protection. Based on this analysis, we found that push–pull semiochemicals can significantly reduce <i>Dendroctonus</i> and <i>Ips</i> populations measured by a reduction in the attraction to lure/trap catches, tree mortality, and attacks on trees. The overall efficacy of the push–pull semiochemical treatment shows a 66% reduction for <i>Ips</i> compared to control and a 54% reduction compared to control for <i>Dendroctonus</i>, while, at the species level, there was a 69% reduction for <i>Dendroctonus ponderosae</i> (Hopkins) and a 94% reduction in <i>Ips perturbatus</i> (Eichhoff), and a 93% reduction in <i>Ips latidens</i> (LeConte). Interestingly, among different treatment sources, the efficacy of conspecific semiochemicals in combination with heterospecific semiochemicals and non-host volatiles showed a 92% reduction in <i>Dendroctonus</i> spp., and conspecific semiochemicals in combination with non-host volatiles showed a 77% significant reduction in <i>Ips</i> spp., while the efficacy of heterospecific semiochemicals in reducing <i>Ips</i> population was about 69%, and 20% in <i>Dendroctonus</i>. Among different ecological regions, the use of a push–pull strategy showed a 70% reduction in <i>Dendroctonus</i> in central-west North America, and <i>Ips</i> showed a 75% reduction in southwest North America. Our results demonstrate that semiochemical-based push–pull techniques have the potential to reduce <i>Dendroctonus</i> and <i>Ips</i> bark beetle populations. Furthermore, based on our analysis, the efficacy of such eco-friendly interventions could be further improved and provide a good tool for forest managers to control these pests, at least under some circumstances.
