Agrilus quercicola (Fisher) (Coleoptera: Buprestidae), the Gambel Oak Borer, as a Pest of Quercus spp.By Andrea Sever, Whitney Cranshaw, Robert Brudenell
Southwestern Entomologist, 2012
During 2003 an unusual outbreak of the Gambel oak borer, Agrilus quercicola (Fisher), caused extensive damage to several species of oak in Denver, Araphaoe, and Douglas counties in Colorado. This followed several seasons of environmental stress that predisposed Gambel oak to the insect, but adults apparently dispersed more than 30 km during this outbreak to kill oaks a considerable distance from native Gambel oak stands. In choice tests, adults fed on foliage of Gambel oak, but not other herbaceous shrubs common in stands of Gambel oak. Yellow and neon yellow-green, but not white, sticky traps caught considerable numbers of adults. Adult flight activity began in late May, peaked in early summer, and ended in late August. A chalcid parasitoid, Phasgonophora sulcata Westwood, was noted to be an important natural enemy. No injury by this insect has been observed outside of native Gambel oak in years subsequent to the 2003 outbreak.

Barr, W.F. 2008. Two new species of Agrilus
Curtis 1825 from Arizona and Texas, with a new synonymy in Agrilus
(Coleoptera: Buprestidae). Zootaxa 1681: 31-36.
Two new species of the genus Agrilus
Curtis, are described:
n. sp. from Arizona and
n. sp. from Texas.
A new synonymy is proposed: A. pubescens
Fisher 1928 (= A. parapubescens
Knull 1934), syn. nov.
Also, joint ecological and distributional associations are presented for A. montosae
, through the co-presence of A. pectoralis Waterhouse, A. near impexus Horn, A. pubescens Fisher and another buprestid, Chrysobothris lateralis Waterhouse.
