Abstract Healthy pine trees in low-density stands offer the best defense against the southern pine beetle (SPB), helping to ensure that timber resources and other benefits of forests are protected against infestations. Through the SPB prevention cost-share program, landowners of nonindustrial private forestland are able to receive a financial incentive for improving forest health by proactively undertaking forest management practices. In this study, two surveys were used to analyze this program: (1) a survey of enrollees in the SPB prevention cost-share program, and (2) a survey of forest landowners who have not participated in a cost-share program. Data are used to examine similarities and differences in the two samples (e.g., background awareness of the SPB, sources of their information about the SPB). Information obtained from cost-share program enrollees is also presented to characterize their participation and to provide an overall evaluation of the program. Data indicate that the SPB prevention cost-share program is very successful in terms of the satisfaction of its customers (i.e., the actual program participants).

Abstract The southern pine beetle (SPB) Dendroctonus frontalis Zimmermann, is the most important insect pest of pines in the southeastern United States, with outbreaks often resulting in thousands of hectares of pine mortality. Natural enemies and competitors have been cited as significant regulators of SPB populations and, therefore, outbreaks. A recent outbreak on the Homochitto National Forest (NF) in Mississippi provided an opportunity to undertake a case study comparing population fluctuations of SPB, its major predator Thanasimus dubius, and its competitors, Ips bark beetles. Trap catches of all three were tracked through the course of the outbreak on the Homochitto NF as well as in two other forests with low or no SPB activity. The number of predators collected initially increased on the Homochitto NF in response to the SPB outbreak, but their impact on reducing infestation numbers was unclear. Numbers of Ips trapped were similar across all three forests, indicating that other factors were regulating SPB populations. The outbreak only lasted a single year, and its brevity likely limited the availability of host resources for natural enemy and competitor populations. Additional studies are warranted to explore the mechanisms affecting the extent and duration of SPB outbreaks, such as active forest management. Study Implications: The widespread application of cut-and-leave treatments during a short duration southern pine beetle (SPB) outbreak on the Homochitto National Forest did not result in immediate increased collections of Ips bark beetles, competitors of SPB. Similar population trends of Ips bark beetles in areas with and without SPB infestations suggest that other factors, such as climate, regulate population numbers. Low numbers of the main SPB predator, Thanasimus dubius, immediately preceded an outbreak, and trap collections increased after outbreak onset, reaffirming the importance of this natural enemy in SPB population fluctuations.
