AbstractThe life cycle of Corticeus glaber (LeConte) was investigated at 25 °C and 60% R.H. The developmental time from egg to adult for C. glaber ranged from 30 to 41 days and five larval instars were determined from head capsule measurements. The mature larva is described.

AbstractUnder laboratory conditions, Corticeus glaber (LeConte) and C. parallelus (Melsheimer) adults were facultative predators of southern pine beetle, Dendroctonus frontalis Zimmermann, eggs and first and second instar larvae. Southern pine beetle frass and blue stain fungus, Ceratocystis minor (Hedgecock) Hunt were also suitable for survival for both species of Corticeus. Loblolly pine (Pinus taeda L.) phloem was not utilized as a food source by either species. Corticeus spp. larvae were predators of D. frontalis eggs.

AbstractIn southern Louisiana, Corticeus glaber (LeConte) outnumbered Corticeus parallelus (Melsheimer) 3.7:1 during 15-month study from October 1976 to December 1977. Corticeus spp. varied significantly (P < 0.01) among the 52 sample dates and three sample heights on infested tree boles. Corticeus spp. were significantly correlated with numbers of southern pine beetle eggs, Dendroctonus frontalis Zimmermann, in the bottom and middle samples but not in the top sample. Corticeus glaber peak arrival occurred from 14 days prior to 14 days following pine beetle mass attack, while C. parallelus peak arrival occurred from 7 days prior to 10 days following pine beetle mass attack.

Winter Temperatures

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.

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.

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.

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.
