A mathematical model of field population dynamics of the southern pine beetle, dendroctonus frontalis

Abstract Several areas throughout the southern Appalachians were sampled to determine the extent of southern pine beetle (Dendroctonus frontalis Zimmerman) brood mortality following a winter with subzero (F°) temperatures. Although 95-percent brood mortality may occur, results suggest that low winter temperatures may not be the sole reason for the decline of a southern pine beetle outbreak.

Pine Beetle

Abstract A statistical model has been developed that relates percentage change in the large area coverage of southern pine beetle outbreaks (Dendroctonus frontalis Zimm.) to temperature and moisture status indices. It is applicable over the entire range of epidemic outbreaks during the last quarter-century. The interactive computer program, SPBCMP, can be used to assess the likelihood of major changes in coverage several months prior to the period of maximum activity. SPBCMP requires only location and four easily accessed climatic parameters. Climatic data for these driving variables can be supplied by the user obtained from a file maintained on the University of Virginia Academic Computing System. The program instructs the user on how to access that data. An additional feature of SPBCMP is that it allows for sensitivity analyses based on weather scenarios for upcoming months. South. J. Appl. For. 10:158-61, Aug. 1986.

Pine Beetle

AbstractGlucose, fructose, and sucrose were the only sugars detected in inner bark treated with a southern pine beetle–microorganism complex and two beetle-associated fungi. Treatments drastically lowered the reducing-sugar level. Storage of untreated bolts had no effect on reducing-sugar level; sucrose was lowered but not as much as in treated tissue. Starch content remained unchanged in all treatments.

Multiple Tree

Abstract Data on the geographical distribution and frequency of multiple-tree infestations of southern pine beetle (SPB) (Dendroctonus frontalis Zimm.) collected in North Carolina from 1960-1980 were analyzed. A Geographical Information System (GIS) was used to construct a map showing geographical distribution of SPB from 1960-1980. Beetle intensity, measured in numbers of infestations (spots)per thousand acres of host type, is shown. The authors point out that infestation intensities vary geographically. The location of pine timberland in respect to SPB hazard may dictate economic and silvicultural strategies for managing southern pines. South. J. Appl. For. 18(4): 145-146.

Detection Evaluation

Abstract This article summarizes four USDA agricultural handbooks dealing with detection, evaluation, suppression, and prevention of the southern pine beetle, Dendroctonus frontalis Zimmermann. Among topics covered are aerial location and evaluation of spots, techniques for assigning groundcheck and control priorities, and recommended direct-control techniques. Since the primary thrust of good pest management should be pest prevention by maintaining tree vigor, preventative silviculture guidelines are also presented.
