The emerald ash borer (EAB), Agrilus planipennis Fairmaire (Coleoptera: Buprestidae) is a serious invasive pest that has caused devastating mortality of ash trees (Fraxinus sp., Oleaceae) since it was first identified in North America in 2002. Shortly after its discovery, surveys were conducted, based on the visual inspection of trees. The shortcomings of visual surveys have led to a critical research need to find an efficient survey method for detecting A. planipennis infestations. Here, we present a review of research that has led to the development of effective trapping methods for A. planipennis. Studies on the insect's biology and behavior have led to the identification of several potential attractants as well as the design of a visually attractive trap. The ongoing challenge in developing an optimally efficient trapping methodology for A. planipennis will involve finding the best combination of variables, such as trap shape, trap color (or other visual properties), trap placement, lure components, as well as the ratios and release rates of those components.

The invasive emerald ash borer (Agrilus planipennis Fairmaire) (EAB) has been devastating North American ash (Fraxinus spp.) resources for over 2 decades. In its native range, EAB attacks and kills primarily stressed ash trees.

Jewel beetles pose significant threats to forestry, and effective traps are needed to monitor and manage them. Green traps often catch more beetles, but purple traps catch a greater proportion of females. Understanding the function and mechanism of this behavior can provide a rationale for trap optimization.

Article Synopsis
- Understanding the evolution of genomic variation is essential for creating effective conservation strategies for threatened species, focusing on connectivity, demographic changes, and environmental adaptation.
- The study analyzed genomic variation in Fraxinus latifolia, a riparian tree facing threats from the invasive emerald ash borer, by sequencing over 1000 individuals from 61 populations.
- Results showed strong population structure and low genetic diversity, suggesting that this patchy distribution could hinder the species' long-term evolutionary potential, underscoring the importance of conserving genomic diversity for future restoration efforts.

Population outbreaks are characterized by irruptive changes in population density and connectivity resulting in rapid demographic and spatial expansion, often at the landscape scale. Outbreaks are common across multiple taxa, many of which inhabit northern ecosystems. Outbreaks of Lepidopteran defoliators in forest ecosystems are a particularly compelling example of this phenomenon, given the massive spatial scales over which these outbreaks can occur, their frequency, and socioeconomic impacts.

Article Synopsis
- The emerald ash borer (EAB) is a serious global pest, and accurately detecting it is essential for effective management, but traditional methods are often insufficient for large-scale monitoring.!* -
- Research reveals that differences in Leaf Area Index (LAI) and leaf sizes due to EAB infestation become significant in July, with detection accuracy rising from 88.57% before July to 100% after.!* -
- The optimal time for monitoring EAB is highlighted, suggesting field surveys should occur from May to November and remote sensing from August to October, improving detection and management strategies.!*
