The southern pine beetle, Dendroctonus frontalis Zimmermann, is native to pine forests of the southern United States. We describe here techniques for enhancing parasitoid efficacy by direct feeding of parasitoid adults. Our recent research suggests that feeding by female adult D. frontalis parasitoids is important for increased longevity (Mathews and Stephen 1997, 1999; Stephen et al. 1997), and we documented that, with parasitoid feeding, egg resorption decreases and development of new immature eggs increases (Hanano 1996). We suspect that food for D. frontalis parasitoids, in the form of nectar, pollen, or honeydew, is not always available in the forest. We are developing a commercial D. frontalis control strategy based on this assumption.

Morphological Differences

AbstractSeven species of mites (Acari: Tarsenomidae) were associated with two local outbreaks of the southern pine beetle, Dendroctonus frontalis Zimmerman, in Chiapas, Mexico; three of these species were new records for Mexico and Central America. The morphology and phoretic behavior of these mites differed little between the western and southern populations from the United States. One major difference was that the hyperphoretic ascospores of the southern pine beetle mycangial fungus, Ceratocystiopsis sp. (Ophiostomataceae), were common in sporothecae of Tarsonemus krantzi Smiley and Moser (Acari: Tarsonemidae) and Tarsonemus ips Lindquist in Chiapas, Mexico, whereas the ascospores of the blue stain fungus, Ophiostoma minus (Hedgcock) H. and P. Sydow (Ophiostomataceae), were rare; this situation in the southern United States is reversed. The paucity of behavioral and morphological differences between the two southern pine beetle populations and the relevant historical climatology suggest that the appearance of D. frontalis in the southern United States may be a recent event.

The southern pine beetle, Dendroctonus frontalis, is a native pest of pine trees that has recently expanded its range into the northeastern United States. Understanding its colonization, dispersal, and connectivity will be critical for mitigating negative economic and ecological impacts in the newly invaded areas. Characterization of spatial-genetic structure can contribute to this; however, previous studies have reached different conclusions about regional population genetic structure, with one study reporting a weak east-west pattern, and the most recent reporting an absence of structure. Here we systematically assessed several explanations for the absence of spatial-genetic structure. To do this, we developed nine new microsatellite markers and combined them with an existing 24-locus data matrix for the same individuals. We then reanalyzed this full dataset alongside datasets in which certain loci were omitted with the goal of creating more favorable signal to noise ratios. We also partitioned the data based on the sex of D. frontalis individuals, and then employed a broad suite of genotypic clustering and isolation-by-distance (IBD) analyses. We found that neither inadequate information content in the molecular marker set, nor unfavorable signal-to-noise ratio, nor insensitivity of the analytical approaches could explain the absence of structure. Regardless of dataset composition, there was little evidence for clusters (i.e., distinct geo-genetic groups) or clines (i.e., gradients of increasing allele frequency differences over larger geographic distances), with one exception: significant IBD was repeatedly detected using an individual-based measure of relatedness whenever datasets included males (but not for female-only datasets). This is strongly indicative of broad-scale female-biased dispersal, which has not previously been reported for D. frontalis, in part owing to logistical limitations of direct approaches (e.g., capture-mark-recapture). Weak spatial-genetic structure suggests long-distance connectivity and that gene flow is high, but additional research is needed to understand range expansion and outbreak dynamics in this species using alternate approaches.

The southern pine beetle, Dendroctonus frontalis Zimmermann, is the most destructive insect pest of pine in the southern United States. This 8-page fact sheet written by Demian F. Gomez and Jiri Hulcr and published by the UF/IFAS Department of Entomology and Nematology describes the beetle and includes advice on how to monitor for them and strategies for their prevention and control. http://edis.ifas.ufl.edu/in333

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.
