Introduction Decision support models that predict both when and where to expect emerald ash borer (EAB), Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), are needed for the development implementation of effective management strategies against this major invasive pest ( Fraxinus species) in North America other regions such as Europe. We present a spatialized model phenology climatic suitability EAB use Degree-Days, Risk, Phenological event mapping (DDRP) platform, which is an open-source decision tool help detect, monitor, manage threats. Methods evaluated using presence records from three geographic (China, America, Europe) phenological dataset consisting primarily observations northeastern midwestern United States.

The invasive emerald ash borer (Agrilus planipennis Fairmaire) (EAB) has been devastating North American (Fraxinus spp.) resources for over 2 decades. In its native range, EAB attacks and kills primarily stressed trees. America, however, also healthy trees of every Fraxinus species encountered, most recently Oregon latifolia Benth.). Successful development reported in European olive (Olea europaea L.). recent detection puts the future these hosts into question, as little is known about EAB's or how introduced biocontrol agents will respond. We conducted laboratory field infestations Delaware to assess associated parasitoid responses. found no difference net population growth rate developing versus green ash. However, supported significantly more than olive, which was zero, with larvae dying prematurely. Artificially infested olives were small, may have negatively impacted phloem availability larval survival. Future studies should be investigating on larger material. Although parasitism observed seldom reached life stages (third fourth instars) susceptible parasitism, late-instar attacked by both Tetrastichus planipennisi Yang Spathius galinae Belokobylskij Strazanac, suggesting that a suitable option this newly invaded region.

Emerald ash borer (EAB, Agrilus planipennis Fairmaire) is an Asian woodborer that a destructive pest of (Fraxinus spp.) trees throughout North America and in parts Asia Europe. It has killed hundreds millions worldwide the past two decades shown some ability to infest novel hosts, most notably white fringetree (Chionanthus virginicus L.). Here, I review evidence this beetle can succeed on cultivated olive (Olea europaea L), close relative fringetree. Studies observations thus far indicate that, while young are largely resistant EAB larval development, adults will oviposit trees, feed their foliage produce viable eggs, larger, older possibly stressed have potential support development adult stage field. soon interact with wild U.S. Europe, realized risk olives by be revealed.

Specificity and Sensitivity of a Rapid LAMP Assay for Early Detection of Emerald Ash Borer (Agrilus planipennis) in Europe

Forests, Journal Year: 2023, Volume and Issue: 14(2), P. 436 - 436

Published: Feb. 20, 2023

Buprestids are an emerging threat to broadleaf forests across the world. Species such as emerald ash borer (EAB, Agrilus planipennis) seriously threaten (Fraxinus spp.) in North America and Europe. As it continues spreading west from European Russia, native populations will suffer dramatic losses. Due their cryptic lifestyle of egg larval stages on developing bark vascular tissue, buprestids other wood borers can be difficult detect. Early detection tools vital implement fast eradication measures, prevent establishment invasive species populations. Detection methods using polymerase chain reaction (PCR) assays target specific taxa extremely timely obtain results especially since samples need transported laboratory first. However, loop-mediated isothermal amplification (LAMP) eDNA highly sensitive providing within 30 min after sample extraction. In this study, we investigated specificity sensitivity EAB LAMP assay early tool The was when tested against 12 spp., five buprestids, two Scolytinae, cerambycids (n = 24). amplified DNA a concentration low 0.02 pg/µL. These demonstrate that is specific, used detect monitor urban settings.

Abstract We examined the health of mature blue ash, Fraxinus quadrangulata , in two forests southwestern Ohio relation to that white ash F. americana and potential importance oviposition preferences larval resistance persistence ash. Both were largely unaffected by emerald borer 2012. By 2018, nearly 90% trees observed these had full or canopies, as opposed less than 20% encountered our studies. In 2021, maintained a similar degree canopy but no standing live ashes remained. Bark removals revealed current past feeding attempts 2018 except for one attacked killed tree 2018. All attacked. laboratory bioassay with cut stems, larvae fed grew significantly more slowly on reduced performance adult likely contribute devastated borer.

Feeding, Survival, and Fecundity of Adult Emerald Ash Borer (Coleoptera: Buprestidae) on Foliage of Two Novel Hosts and Implications for Host Range Expansion

Environmental Entomology, Journal Year: 2020, Volume and Issue: 49(3), P. 709 - 716

Published: April 2, 2020

Insect herbivores are more likely to successfully use a novel host if the plant is closely related ancestral and insect polyphagous. Emerald ash borer (EAB), Agrilus planipennis (Fairmaire) (Coleoptera: Buprestidae), specialist wood of (Fraxinus spp., Lamiales: Oleaceae) trees one most destructive forest pests in North American forests. Recent studies have found that larvae can develop stems two relatives; white fringetree (Chionanthus virginicus (L.) [Laminales: Oleaceae]) cultivated olive (Olea europaea Oleaceae]). For EAB adults, ability consume, mate, lay viable eggs on foliage these hosts unknown. Thus, we conducted no-choice assays with adult paired positive controls susceptible ash. Larval performance was also examined reciprocal study cut green pennsylvanica Marshall) determine whether diet impacted success progeny. Longevity, consumption rates, fecundity adults were similar foliage. In contrast, consuming died quickly, consumed over time, females laid far fewer compared those Adult did not impact larval success, but grew slower. These results indicate suitable for complete its lifecycle, although perform poorly this than species. distantly appears be poor EAB, some produced by females.

Herbicide Stress Inducesbeetle Oviposition on Red Maples

Journal of Chemical Ecology, Journal Year: 2024, Volume and Issue: 50(9-10), P. 515 - 528

Published: Aug. 26, 2024

Flatheaded borers (FHB; Chrysobothris spp.), are woodboring-beetles that lay their eggs in the bark and cambium of deciduous trees North America. Females often target stressed host-plants for oviposition. The reason why is unknown; however, plants suffer various induced phytochemical changes may enhance larval infestation success depending on stressor such as upregulation defenses, reallocation nutrients, to volatile organic compound (VOC) emissions. To understand attraction FHB specific stress-induced changes, we analyzed associated with stress treatments attractiveness maple FHB. Trees were by: (1) chemical (pelargonic acid herbicide), (2) physical (physically removing leaves), (3) (removing portions near root crown). After reflush defoliated trees, tissues where larvae feed nutritional (carbon nitrogen), anti-nutritive (polyphenols tannins) emissions foliar VOCs. At end growing season, assessed presence oviposition attempts. There more attempts by herbicide application. Compared other treatments, herbicide-stressed had greater nitrogen total polyphenol concentrations. Greater play a role fitness feeding larvae, concentration stimulate female trees. be able locate using cues increases limonene, α-farnesene, (E)-4,8-dimethyl-1,3,7-nonatriene (DMNT) hexenyl acetate.
