  • The Goldspotted Oak Borer: Revisiting the Status of an Invasive Pest Six Years After 1 Its Discovery
    The Goldspotted Oak Borer: Revisiting the Status of an Invasive Pest Six Years After 1 Its Discovery 2 3 Steven J. Seybold and Tom W. Coleman Abstract The goldspotted oak borer, Agrilus auroguttatus (Coleoptera: Buprestidae), was first associated with oak mortality in San Diego County, California in May of 2008. Since that time, a research and survey program has outlined the biology of this flatheaded borer in the invaded and native habitats; delimited the invaded range; and developed the components of an integrated pest management (IPM) program. Significant advances have been made in the understanding of its host range, feeding habits, life cycle, and natural enemies in Arizona and California. Some research progress has also been made on the evaluation of techniques for the detection of the pest and treatments to ameliorate its damage. Since the original discovery, we have learned that A. auroguttatus feeds primarily on red oaks in the section Lobatae and that although its landscape-level impacts unfold slowly, it appears to be capable of killing these trees without the aid of abiotic or other biotic factors. The biology, behavior, and impact of A. auroguttatus have also been contrasted with a less well understood sibling species, the Mexican goldspotted oak borer, Agrilus coxalis. The key questions remaining about A. auroguttatus are: 1) Has sufficient progress been made to facilitate a functional IPM program should the expanding distribution of A. auroguttatus reach the urban oaks of the Los Angeles basin or woodland oaks in the foothills of the Sierra Nevada? and 2) Can we assess the risk and predict the population expansion to these lands? Key words: Agrilus auroguttatus, California black oak, canyon live oak, coast live oak, goldspotted oak borer, mortality agent Introduction The goldspotted oak borer (GSOB), Agrilus auroguttatus (Coleoptera: Buprestidae) (fig.

  • Mapping Spread of the Goldspotted Oak Borer (Agrilus Auroguttatus)1
    Mapping spread of the Goldspotted Oak Borer (Agrilus auroguttatus)1 Thomas A. Scott,2,3,4 Kevin Turner,3,4 Cara Washington,4 and Kim 5 Corella Abstract The earliest signs of goldspotted oak borer (Agrilus auroguttatus, GSOB)-associated oak declines can be found in 1996 aerial photo images from the Descanso area of San Diego County. By 2014, GSOB had spread over a 4000 km2 area, with a patchy distribution similar to the early spread of the emerald ash borer (Agrilus planipennis). The GSOB occurs over about 26,250 ha (60 percent) of the oak woodlands in its primary range of infestation; with heaviest damage near rural housing and communities. Three GSOB diaspora have occurred 30, 40, and 55 km from closest known infestation areas, implicating human transport rather than adult flight as the agent of dispersal. Sequential aerial photo plots suggest that individual oaks (7916) took a median of 3 years to die after first sign of canopy decline, and 95 percent died within 8 years. Plots with >9 years of GSOB attack lost up to 76 percent of their oak canopies, with up to 25 percent of canopy loss/year in drought years. Oak canopy losses averaged about 3 percent of total area/year, or the equivalent of about four large, mature oak trees/ha/year. Years of high precipitation slowed GSOB mortality, followed by rapid increases in mortality when these years were followed by a drought year. Key words: Agrilus auroguttatus, forest pest, goldspotted oak borer, GSOB, oak management, oak woodlands, Quercus agrifolia, Quercus chrysolepis, Quercus kelloggii Introduction Oak mortality in San Diego County rapidly increased in the fall of 2002, the fourth year of a 5-year drought.

  • Goldspotted Oak Borer
    Goldspotted Oak Borer What is Killing the Oaks? The Goldspotted Oak Borer, Agrilus coxalis Waterhouse The goldspotted oak borer (GSOB) was first detected in 2004 in San Diego Co., California by the California Department of Food and Agriculture during a survey for exotic woodborers. In 2008, it was found attacking coast live oak, Quercus agrifolia, canyon live oak, Q. chrysolepis, and California black oak, Q. kelloggii, on the Cleveland National Forest and Cuyamaca Rancho State Park. GSOB is playing a major role in on-going oak mortality. GSOB larvae feed under the bark primarily at the interface of the sapwood and phloem on the main stem and larger branches. Larvae kill patches and strips of phloem and cambium, resulting in limb and branch die back and, eventually, tree death. Because of host distribution, GSOB has the potential to spread further north in California and cause similar tree mortality. Because of this, all Oak firewood has been quarantined in both the Cleveland National Forest and Cuyamaca Rancho State Park. Efforts are under way to keep oak firewood from leaving San Diego County For more information go to http://groups.ucanr.org/GSOB/ --------------------------------------------------------------------------------------------------------------------- --------------------- The goldspotted oak borer (GSOB), Agrilus auroguttatus (Coleoptera: Buprestidae), is a flatheaded borer introduced to San Diego County, California, in the late 1990s or early 2000s and also detected at one site in Riverside County in 2012. It was likely brought into the state on oak firewood collected and transported from the insect’s native range in southeastern Arizona or northern Mexico. Although currently confined to San Diego and Riverside counties, this pest will likely invade other areas of California.

  • Mini Data Sheet on Agrilus Auroguttatus
    EPPO, 2017 Mini data sheet on Agrilus auroguttatus Added in 2013 – Deleted in 2017 Reasons for deletion: Agrilus auroguttatus is perceived as a risk for the EPPO region and surveys have been conducted by several EPPO countries. However, trade from areas where this insect occurs is limited and European species of oak are not considered susceptible. In 2017, the Working Party on Phytosanitary Regulations agreed that it could be deleted, considering that sufficient alert has been given. Agrilus auroguttatus (Coleoptera: Buprestidae - goldspotted oak borer) Why: Agrilus auroguttatus (Coleoptera: Buprestidae - goldspotted oak borer) has recently been introduced into California (US) where it attacks oak trees. Although A. auroguttatus is a North American species probably originating from Arizona (US), its introduction into California is considered to be a serious threat to native oak species. Because extensive tree mortality has been observed in California, the Panel on Phytosanitary Measures decided that A. auroguttatus should be added to the EPPO Alert List. Where: A. auroguttatus is morphologically very similar to Agrilus coxalis which ranges from central Mexico to Guatemala. Over the years, several authors have considered that they represented either the same species or subspecies of A. coxalis (A. coxalis coxalis and A. coxalis auroguttatus). At present, it seems accepted that they are distinct species; that the pest introduced into California is A. auroguttatus; and that A. auroguttatus originates from Southern Arizona (most probably from the Dragoon Mountains area). In California, the first outbreaks were observed in 2004 in the San Diego county (Descanso, Guatay, Pine Valley), although it is suspected that the pest has probably been present since the early 2000s.

Reason for Inclusion in Manual The U.S. Forest Service recommended the addition because of the mortality that A. auroguttatus is causing to oaks in California. Taxonomy The scientific name for the goldspotted oak borer has gone through several taxonomic changes in the past few years. It was listed in the 2011 EWB/BB manual as the sub-species A. coxalis auroguttatus. There is a separate species that is present in Mexico and not in the United States that was previously listed at the sub-species level as A. coxalis coxalis. Now, A. coxalis auroguttatus has risen to species status and is referred to as A. auroguttatus. A. coxalis coxalis is now A. coxalis. The following is a history of the taxonomy: 1.

    Research Article Received: 29 July 2014 Revised: 24 November 2014 Accepted article published: 9 December 2014 Published online in Wiley Online Library: 14 January 2015 (wileyonlinelibrary.com) DOI 10.1002/ps.3959 Impact of the goldspotted oak borer, Agrilus auroguttatus, on the health of coast live oak before and after treatment with two systemic insecticides Yigen Chen,a* Mary L Flint,a Tom W Coleman,b Joseph J Doccola,c Donald M Grosman,c David L Woodd and Steven J Seybolde Abstract BACKGROUND: The invasive goldspotted oak borer, Agrilus auroguttatus, is threatening the health and survival of oak trees in San Diego County, California. From two sites in the core area of the infestation, we report a 2.5 year investigation of the impact of A. auroguttatus on coast live oak, Quercus agrifolia, before and after treatment with two systemic insecticides, emamectin benzoate (EB) and imidacloprid (IC). RESULTS: None of the 446 survey trees died during the study. The crown dieback rating of most trees at both study sites remained unchanged, regardless of insecticide treatment. A higher cumulative increase in the number of A. auroguttatus emergence holes was observed on trees that were previously infested and on trees with larger diameters. Over the 2.5year period, the new infestation rates of initially uninfested trees across the untreated and treated groups were 50% (EB) and 32% (IC), and neither EB nor IC treatment affected cumulative increases in the number of emergence holes. EB-injected trees did not have significant annual increases in the number of A. auroguttatus emergence holes at either 1.5 or 2.5 years compared with that at 0.5 years, whereas untreated trees had significant annual increases.
