Abstract The emerald ash borer (EAB), a phloem-feeding beetle native to Asia, was discovered killing trees in southeastern Michigan and Windsor, Ontario, 2002. Like several other invasive forest pests, the EAB likely introduced became established highly urbanized setting, facilitated by international trade abundant hosts. Up 15 million urban forested settings have been killed EAB. Quarantines United States Canada restrict movement of trees, logs, firewood prevent new introductions. Research...

The saga of the emerald ash borer, Agrilus planipennis Fairmare (Coleoptera: Buprestidae), in North America began on 25 June 2002, when five entomologists representing Michigan State University (MSU), Department Natural Resources (MDNR), and U.S. Agriculture, Animal Plant Health Inspection Service (USDA APHIS) visited Detroit to examine declining (Fraxinus spp.) trees.

Emerald ash borer (Agrilus planipennis Fairmaire) (Coleoptera: Buprestidae), an invasive phloem-feeding pest, was identified as the cause of widespread (Fraxinus) mortality in southeast Michigan and Windsor, Ontario, Canada, 2002. A. reportedly colonizes other genera its native range Asia, including Ulmus L., Juglans Pterocarya Kunth. Attacks on nonash species have not been observed North America to date, but there is concern that could be colonized. From 2003 2005, we assessed adult landing...

New infestations of emerald ash borer, Agrilus planipennis Fairmaire, an invasive pest native to Asia, are difficult detect until densities build and symptoms appear on affected ( Fraxinus spp). We compared the attraction A. trees stressed by girdling (bark phloem removed from a 15 cm wide band around tree (2003–2005)), vertical wounding (same area bark in strip (2004)), herbicide treatment (Pathway applied with Hypo-Hatchet injector (2003) or basal application Garlon 4 (2004, 2005)),...

Emerald ash borer, Agrilus planipennis (Fairmaire) (Coleoptera: Buprestidae), a phloem-feeding beetle native to Asia, has become one of the most destructive forest pests in North America. Since it was first identified 2002 southeast Michigan and Windsor, Ontario, dozens isolated A. populations have been discovered throughout 12 other states province Quebec. We assessed realized dispersal at two discrete outlier sites that originated 1 yr 3 earlier from infested nursery trees. systematically...

Bark volatiles from green ash Fraxinus pennsylvanica were tested for electrophysiological activity by Agrilus planipennis using gas chromatographic-electroantennographic detection (GC-EAD) and behavioral baited purple traps in Michigan. GC-EAD analysis of the headspace bark tissue samples 0- 24-h-old fully girdled (stressed) trees showed that latter had elevated sesquiterpene levels. Six compounds consistently elicited antennal responses both male female A. planipennis. Five antennally...

Emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), has killed millions of (Fraxinus sp.) trees in North America since its discovery Michigan 2002. Efficient methods to detect low-density A. populations remain a critical priority for regulatory and resource management agencies. We compared the density adult captured on sticky bands larval among that were girdled 1 or 2 yr, wounded, exposed stress-elicitor methyl jasmonate, baited with Manuka oil lures, left untreated....

Emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), a phloem-feeding beetle native to East Asia, was first discovered in southeast Michigan and Essex County, Ontario, June 2002 has since killed millions of (Fraxinus spp.) trees North America. Initial studies indicated that the life cycle A. univoltine but more recent observations some larvae feed for two summers, resulting 2-yr cycle. Understanding factors affect attraction development on host could improve detection...

Effective methods are needed to protect ash trees (Fraxinus spp.) from emerald borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), an invasive buprestid that has killed millions of North American trees. We randomly assigned 175 (11.5-48.1 cm in diameter) 25 blocks located three study sites Michigan one seven insecticide treatments May 2007. Treatments included 1) trunk-injected emamectin benzoate; 2) imidacloprid; 3) basal trunk spray dinotefuran with or 4) without Pentra-Bark,...

This study provides the most detailed description of immature stages Agrilus planipennis Fairmaire to date and illustrates suites larval characters useful in distinguishing among Curtis species instars. Immature eight were examined imaged using light scanning electron microscopy. For A. all preimaginal (egg, instars I-IV, prepupa pupa) described. A combination 14 character states identified that serve identify larvae planipennis. Our results support segregation into two informal assemblages...

We studied the host selection behavior and feeding preference of emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae). A. is an exotic forest insect pest native to Asia that was discovered in North America 2002 causing widespread mortality trees (Fraxinus spp.) southeast Michigan surrounding states. compared on different species including Manchurian (F. mandshurica Rupr.), green pennsylvanica Marsh), white americana L.), black nigra blue quadrangulata Michx.), European...

Wood-boring beetles in the family Cerambycidae (Coleoptera) play important roles many forest ecosystems. However, increasing numbers of invasive cerambycid species are transported to new countries by global commerce and threaten health United States worldwide. Our goal was identify effective detection tools for a broad array testing some known attractants pheromone different trap designs placed across range habitats. We compared richness captured with cross-vane panel traps 12-unit Lindgren...

Fluon PTFE is a fluoropolymer dispersion applied as surface conditioner to cross-vane panel traps enhance trap efficiency for cerambycid beetles. We describe the results of three experiments further optimize different designs and test effect over time. tested with Lindgren funnel fitted either wet or dry collection cups on catches beetles how persisted. Fluon-treated captured ≈ 6× more than untreated cups. Untreated did not capture any beetles; however, an average four per trap. ≈9× ≈11× The...

Insects rely on olfaction to locate food, mates, and suitable oviposition sites for successful completion of their life cycle. Agrilus planipennis Fairmaire (emerald ash borer) is a serious invasive insect pest that has killed tens millions North American (Fraxinus spp) trees threatens the very existence genus Fraxinus. Adult A. are attracted host volatiles conspecifics; however, date no molecular knowledge exists in planipennis. Hence, we undertook an antennae-specific transcriptomic study...
