Evolution of the southern pine beetle legacy simulation model "SPBMODEL" using genetic algorithms
SPBMODEL, a legacy southern pine beetle (SPB) simulation model, was translated into a new JavaTM model called Javahog. The Javahog output was verified to be essentially identical to SPBMODEL output by means of standard and paired t-tests. Javahog was placed online and is currently accessible via a …

Southern pine beetle, Dendroctonus frontalis Zimmermann (Coleoptera: Scolytidae): quantitative analysis of chiral semiochemicals
Semiochemicals released from logs infested by southern pine beetle (SPB), <i>Dendroctonus frontalis</i>, from a total of eight infestations located in Texas, South Carolina, and Virginia were collected four to eight days after initial attack. The quantities and chiralities of most semiochemicals, …

The Southern pine beetle, Dendroctonus frontalis Zimm., and associated Coleoptera attracted to dead loblolly pine, Pinus taeda L.
This study tests the hypothesis: Bark beetles initially locate their host trees in a non-random manner. The association of the southern pine beetle (<u>Dendroctonus frontalis</u> Zimm.) and associated Coleoptera with stressed trees suggested the direction for this study. Loblolly pine trees, …

Assessment of the Potential Role of Blizzard Damage in the Spatial Distribution of Southern Pine Beetle Infestation in Unicoi County, Tennessee.
<p>The Southern Pine Beetle, or SPB, (<em>Dendroctonus frontalis</em> Zimmerman) is a bark beetle that is endemic to the Southern forest ecosystem. Beetle populations remain stable for years at a time; however, for reasons not fully understood the beetle undergoes accelerated population growth on …

Development and assessment of remotely derived variables in current southern pine beetle (Dendroctonus frontalis Zimm.) hazard mapping in North Carolina, USA
The southern pine beetle (SPB) (Dendroctonus frontalis Zimm.) is one of the most destructive forest insect pests in the southeastern United States and has historically had a large impact on the forests of North Carolina. Many characteristics of a forest can contribute to SPB susceptibility …

Pest Management Strategies for Longhorn Army Ammunition Plant and an Assessment of Aerial Radiography for Hazard Rating Pine Stands for Southern Pine Beetle Infestation
… and is being developed for hazard rating for southern pine beetle. The purpose of this study was to apply existing sampling methods for various insects and disease at the Longhorn Army Ammunition Plant in Karnak, Texas and to test the effectiveness of aerial videography for hazard rating pine …

The terpenes of Virginia pine (<u>Pinus virginiana mill</u>.), with investigations of their attractancy to the southern pine beetle (<u>Dendroctonus frontalis</u> zimm.)
… analyze the monoterpenes of Virginia pine. The instrument was adjusted for optimum performance prior to sample analysis. Two packed columns with stationary phases of different polarity, Carbowax 20M and polyphenyl ether + Igepal + Versamid-9JO, were used predominantly for analytical …

The Prevalence and Operational Feasibility of Utilizing Pre-commercially Thinned Pine as a Woody Biomass Energy Source
The southern pine beetle (SPB) poses a significant threat to pine forests of the southeastern US. Pre-commercial thinning (PCT) is a commonly used silvicultural practice to mitigate and prevent SPB spread in young southern pine stands. Typically, PCT represents an added management cost to …

Cost share payment and willingness to participate in Virginia's Pine Bark Beetle Prevention Program
Forest management practices which reduce southern pine beetle (SPB) risk benefit not only the landowners who perform them, but all those who draw benefits from southern pine forests in Virginia, especially other forest owners within the same region. One such management practice is pre-commercial …

Biology and host finding of predaceous hister beetles (Coleoptera: Histeridae) associated with Ips spp. (Coleoptera: Scolytidae) in loblolly pine (Pinus taeda L.)
… (Coleoptera) found associated with Ips engraver beetles (Coleoptera: Scolytidae) in Louisiana were Platysoma attenuata LeConte, Pla. cylindrica (Paykull), Pla. parallelum (Say), and Plegaderus transversus (Say). Seasonal abundance of histerids in flight traps coincided with Ips spp. activity in …

Aggregation, dispersal and edge behavior of the bark beetle predator Thanasimus dubius (Coleoptera: Cleridae); potential use in biological control
Bark beetles are major pests of pine forests in North America that can inflict considerable damage and cause severe economic loss. The checkered beetle Thanasimus dubius Fabricius (Coleoptera: Cleridae), an abundant predator in the Eastern USA and Canada, has been suggested to influence the …
