“…Recent invasions of eastern North America by emerald ash borer (A. planipennis Fairmaire) and of southern California by A. auroguttatus Schaeffer have resulted in extensive mortality of ash (Fraxinus spp.) (Cappaert et al 2005, Pugh et al 2011) and oak (Coleman et al 2011), respectively. Larvae of these species construct galleries just under the bark as they feed, which can girdle and ultimately can kill the tree.…”

Bronze birch borer (Agrilus anxius Gory) (Coleoptera: Buprestidae), a specialist wood-borer endemic to North America, is prone to periodic outbreaks that have caused widespread mortality of birch (Betula spp.) in boreal and north temperate forests. It is also the key pest of birch in ornamental landscapes. Amenity plantings have extended the distribution of birch in North America, for which we report an updated map. Life history and phenology also are summarized. Larvae feed primarily on phloem tissue of stems and branches, which can girdle and kill trees. Stressors such as drought, elevated temperature, and defoliation predispose trees to bronze birch borer colonization and trigger outbreaks, which implicates the availability of suitable host material in the bottom-up regulation of populations. Stress imposed by climate change may increase the frequency of outbreaks and alter the distribution of birch. Bronze birch borer has a diverse array of natural enemies, but their role in top-down population regulation has not been studied. There is substantial interspecific variation in resistance to this insect. North American species share a coevolutionary history with bronze birch borer and are much more resistant than Eurasian species, which are evolutionarily naïve. Potential resistance mechanisms are reviewed. The high susceptibility of Eurasian birch species and climatic similarities of North America and Eurasia create high risk of widespread birch mortality in Eurasia if the borer was inadvertently introduced. Bronze birch borer can be managed in amenity plantings through selection of resistant birch species, plant health care practices, and insecticides.

“…The current study shows that P. mortoniae, C. querciphila, and D. verrucaeformis are weakly pathogenic on healthy coast live oak seedlings but it is likely that the effect of these fungal species could be more severe on stressed plants (7,24,32). In a pathogenicity study of fungi isolated from Q. suber in northeast Spain, the number and size of vascular lesions increased when inoculated with Biscogniauxia mediterránea and Phomopsis spp.…”

“…Coast live oak has recently been devastated by infestations of the goldspotted oak borer (GSOB) Agrilus auroguttatus Schaeffer (Coleóptera: Buprestidae), a flat-headed borer introduced from Arizona via infested firewood (7)(8)(9)(10)22). Other important disease agents of coast live oak in northern California include Phytophthora ramorum in forests (42) and Armillaria mellea in urban developments (47).…”

“…Agrilus adults normally lay their eggs under loose bark or in crevices of host plant tissues and rarely cause significant damage; in contrast, Agrilus larvae typically bore into the living tissue (stems, trunks, branches, or roots) of their host plants, interrupt the translocation of water and nutrients as they feed, and can kill plants within one or a few years of infestation (e.g., EAB [22]; GSOB [6]; A. prionurus [9]). In their native habitats, Agrilus populations are generally suppressed by a diverse group of natural enemies and/or host tree resistance and only occasionally become serious pests.…”

“…since its detection in 2002 [4,5]. By contrast, GSOB is native to the oak forests of southwestern Arizona, and while its damage to oak trees in its invaded range has been on a smaller scale, it has killed more than 25,000 oaks in the oak savannahs of California since first discovered there in 2002 [6][7][8]. A few other exotic Agrilus species have also been recently detected in the United States (e.g., soapberry borer-A.…”

and the Korean peninsula) were reviewed to identify parasitoid guilds associated with Agrilus woodborers. There are at least 12 species of hymenopteran parasitoids attacking eggs of Agrilus beetles and 56 species (36 genera), attacking Agrilus larvae infesting various host plants in North America, Asia, and Europe. While most of the egg parasitoids (9 species) belong to the family Encyrtidae, a majority of the larval parasitoids are members of five families: Braconidae (24 species/11 genera), Eulophidae (8 species/4 genera), Ichneumonidae (10 species/9 genera), and Eupelmidae (6 species/5 genera). The highest rate of Agrilus egg parasitism (>50%) was exerted by encyrtid wasps (4 species) in North America, Asia, and Europe. In contrast, the highest rate of Agrilus larval parasitism (>50%) was caused by species in two genera of braconids: Atanycolus (North America) and Spathius (Asia), and one eulophid genus, Tetrastichus (Asia and Europe). Reported rate of Agrilus larval parasitism ichneumonids was frequent in North America, but generally low (<1%). Potential for success in biological control of emerald ash borer (Agrilus planipennis Fairmaire) in the USA with North American native parasitoids and old-association Asian parasitoids is discussed.
