Abstract Interactions during colonization among the southern pine bark beetle guild members Dendroctonus frontalis Zimmermann, Ips avulsus (Eichhoff), and Ips calligraphus (Germar) were investigated in nine loblolly pines, Pinus taeda L. This study examined host...
Abstract This paper develops models of gallery construction, emergence and re-emergence for use in a general population dynamics model of the southern pine beetle, Dendroctonus frontalis Zimmermann. Models of these processes were originally developed from laboratory...
Abstract The southern pine beetle, Dendroctonus frontalis Zimmermann, is a major insect pest of pines in the southern U.S.A. A population dynamics model of D. frontalis within an infestation was developed. The model is based on the integration of several component...
Abstract Role of host disturbance in initiation and growth of infestations of the southern pine bark beetle guild Dendroctonus frontalis Zimmermann, D. terebrans (Olivier), Ips calligraphus (Germar), I. grandicollis (Eichhoff), and I. avulsus (Eichhoff)] was...
Abstract Within-tree populations of the southern pine beetle, Dendroctonus frontalis Zimmermann were examined in shortleaf pines, Pinus echinata (Mill.), with nylon mesh tents enclosing the portion of the bole where beetles were released. The distribution of the...
Abstract Loblolly and shortleaf pines on one study site in the North Carolina piedmont were subjected to attack by varying numbers of southern pine beetle (SPB), Dendroctonus frontalis Zimmermann. Shortleaf pines appeared to be the more susceptible host on this site....
Abstract Loblolly pine, Pinus taeda L., responded to wounding and wounding plus inoculation with two fungal associates of the southern pine beetle (SPB), Dendroctonus frontalis Zimmermann by forming a hypersensitive reaction zone around the wound sites. There was a...
Abstract Southern pine beetle, Dendroctonus frontalis Zimmermann, adults were introduced to 2-m bolts of loblolly, Pinus taeda L., and shortleaf pine, P. echinata Mill., to determine the effect of host species on the beetle's reproductive potential. A multivariate...
Abstract Most bark beetles carry bluestaining fungi of the genera Ceratocystis, Ceratocystiopsis, or Ophiostoma, which are thought to be important to the success of beetles (Whitney, 1984). Among aggressive bark beetles of the genus Dendroctonus, fungi are thought to...
