A Key to Phoretic Mites Commonly Found on Long-Horned Beetles Emerging from Southern Pines

Abstract

Long-horned beetles that attack conifers are usually considered secondary pests because they generally develop in dead and dying trees and are not the cause of tree mortality (Drooz 1985). Recently that status has changed with the realization that a number of species, especially those belonging to the genus Monochamus, are vectors of the pinewood nematode, Bursuphelenchus xylophifus (Steiner and Buhrer). This nematode is the causative agent of pine wilt disease. Most species of conifers endemic to North America are resistant to the wilt disease, but many exotic species are highly susceptible. The introduction of this nematode into Japan had devastating effects on the native pines in that country (Mamiya 1972), and trade restrictions now exist to prevent the introduction of this pathogen into Europe.
