Evidence for Sexual Attraction by the Twolined Chestnut Borer, Agrilus Bilineatus (Weber) (Coleoptera: Buprestidae)

In the eastern deciduous forests of North America, oaks (Quercus spp.) that have been weakened by stress are often attacked and killed by the twolined chestnut borer, Agrilus bilineatus (Weber) (Dunn et al. 1986a). This borer attacks stressed and dying trees but does not attack healthy or dead trees (Haack and Benjamin 1982; Dunn et al. 1986a, 1987).
