Sound production in Leperisinus oregonous Blackman and L. californicus Swaine (Coleoptera:Scolytidae)

Both Leperisinus oregonus and L. californicus are bark beetle species which emerge from Fraxinus latifolia brood logs as sexually immature adults and disperse to living ash. Occasional field observations suggest that, for overwintering and maturation feeding, L. oregonus enter trunks and branches, whereas L.; californicus enter twig crotches, buds and...
