Emerald Ash Borer Management and Research: Decades of Damage and Still Expanding

Annual Review of Entomology, Journal Year: 2023, Volume and Issue: 69(1), P. 239 - 258

Published: Sept. 14, 2023

Since the discovery of ash tree ( Fraxinus spp.) killer emerald borer (EAB; Agrilus planipennis) in United States 2002 and Moscow, Russia 2003, substantial detection management efforts have been applied to contain monitor its spread mitigate impacts. Despite these efforts, pest continues within North America. It has European Ukraine is causing sporadic outbreaks native range China. The dynamics EAB's expansion events appear be linked lack resistant trees invaded ranges, facilitated by abundance or planted American susceptible species. We review recently gained knowledge EAB; ecological, economic, social impacts; past with their successes limitations. also highlight advances biological control, mechanisms resistance, new approaches under development, aim guiding more effective management.

Challenges, tactics and integrated management of emerald ash borer in North America

Forestry An International Journal of Forest Research, Journal Year: 2019, Volume and Issue: unknown

Published: July 24, 2019

Abstract Emerald ash borer (EAB) (Agrilus planipennis Fairmaire), discovered in southeastern Michigan, USA 2002, has become the most destructive and costly invasive forest insect North America. This phloem-boring beetle also invaded Moscow, Russia continued spread of EAB potentially threatens European (Fraxinus spp.) species. review summarizes life history, including interspecific variation host preference, invasion impacts challenges detecting new infestations provides an overview available management tactics. Advances systemic insecticides, particularly emamectin benzoate products applied via trunk injection, have yielded effective practical options both to protect individual trees slow population growth decline on area-wide basis without disrupting natural enemies. Economic costs treating are substantially lower than removal costs, retain ecosystem services provided by trees, reduce sociocultural conserve genetic diversity areas EAB. Girdled highly attractive adults low-density populations debarking small girdled locate larval galleries is detection method. An array woodpeckers, native parasitoids introduced attack stages but mortality variable. Area-wide strategies that integrate insecticide-treated trap biological control can be adapted for local conditions impacts.

Sprouting and seed production may promote persistence of green ash in the presence of the emerald ash borer

Ecosphere, Journal Year: 2016, Volume and Issue: 7(4)

Published: April 1, 2016

Abstract Invasive insects and pathogens have had major impacts on many forest tree species in North America that often affect structure composition. Despite these effects, variation exists the likelihood some native may persist following outbreaks establishment of exotic pathogens. Emerald ash borer ( EAB ; Agrilus planipennis ) has killed millions trees near its introduction point southeastern Michigan, several recent studies area predicted functional elimination green Fraxinus pennsylvanica from landscape. Intensive management yet unaffected stands results such predictions, however, demands data examine potential for persistence host presence invasive. This study examined by measuring surviving trees, regeneration, seed rain characteristics 17 small, near‐pure five consecutive growing seasons. Live experienced 58% mortality due to , significantly less than reported mixed stands. Approximately 20% exhibited signs confirming slowed but is ongoing. Sprouting was dominant mode regeneration every year, 27% large sprouts produced seeds during a mast year 2011. Advanced new seedling resulted sizable level over years even when sapling taken into account. Seed production reduced considerably ‐caused mortality, there no evidence dispersal limited recruitment. These suggest seed‐producing ability small basal sprouts, as well continued low‐level will retain density, allow .

The green ash transcriptome and identification of genes responding to abiotic and biotic stresses

BMC Genomics, Journal Year: 2016, Volume and Issue: 17(1)

Published: Sept. 2, 2016

To develop a set of transcriptome sequences to support research on environmental stress responses in green ash (Fraxinus pennsylvanica), we undertook deep RNA sequencing tissues under various treatments. The treatments, including emerald borer (EAB) feeding, heat, drought, cold and ozone, were selected mimic the increasing threats climate change invasive pests faced by across its native habitat. We report generation assembly from 55 samples into 107,611 putative unique transcripts (PUTs). 52,899 open reading frames identified. Functional annotation PUTs comparison Uniprot protein database identified matches for 63 % 98 with ORFs. Further functional conserved domains assigned gene ontology terms PUTs. Examination transcript expression different libraries revealed that patterns clustered based regardless treatment. treatments further examined identify differential expression. Tens hundreds differentially expressed each A 109 found be consistently up or down regulated three more representing basal response candidate genes ash. In addition, 1956 simple sequence repeats PUTs, which 465 high quality DNA markers designed flanking PCR primers. North American trees have suffered extensive mortality due EAB infestation, creating need breed select resistant genotypes. Stress is an additional concern longevity populations. use genomics could accelerate management efforts. developed provides important information, genetic stress-response genes.
