Mass trapping Verbenone flakes Ips lecontei outbreak in southwestern ponderosa pine forests Large scale outbreaks of bark beetles in recent years have severely impacted forest conditions in the western United States. In response to these outbreaks, the USDA Forest Service in cooperation with the Western Forestry Leadership Coalition drafted a report (2002) that called for increased short-and long-term treatments and development of research tools to mitigate bark beetle-caused impacts. Subsequently, the Forest Service Forest Health Protection (FHP) began the Western Bark Beetle Initiative in FY 2004. One component of the Initiative was a collaborative effort between FHP and Forest Service Research & Development (R&D); the goal being to accelerate development of management tools for control of bark beetles in the western U.S. During FY 2004 and FY 2005, $1,280,000 of FHP funds were allocated to address development of prioritized topics. FHP representatives from the Bark Beetle Technical Working Group reviewed submitted proposals and evaluated funded projects. This report assesses collaborative efforts between FHP and R&D to accelerate development of new management tools for western bark beetles. This assessment is divided into the following sections: 1) Background information on the Initiative 2) Accomplishments to date relative to high priority needs 3) Critical technology and methodology gaps that remain 4) Evaluation of the interaction between FHP and R&D 5) Conclusions on success of the Initiative and recommendations for future funding direction Advancements were made on several management tools used to control western bark beetles. Twenty-seven projects fully or partially funded by the Initiative have been completed or will be concluded by the end of FY 2006. Major accomplishments to date include: • Development of semiochemical and trapping technology to improve monitoring, suppression, or prevention of bark beetles. The combined use of anti-aggregation pheromones and non-host volatiles shows increasing promise for area and individual tree protection against certain pine-infesting bark beetles. • Evaluation of new insecticides for protecting individual trees or of existing insecticides for novel bark beetle species. For example, Onyx and Permethrin +C™ were shown to be equally effective as the industry standard, Sevin SL™, in protecting cypress and juniper trees against bark beetle (Phloeosinus species) attack. In addition, preliminary evidence suggests that two new systemic insecticides (emamectin benzoate and fipronil) may be effective in preventing attacks by a number of different bark beetle species. If additional short-term funding becomes available for improving management tools for western bark beetles, priority should …

Fuels and fire behavior dynamics in bark beetle-attacked forests in Western North America and implications for fire management

Declining forest health attributed to associations between extensive bark beetle-caused tree mortality, accumulations of hazardous fuels, wildfire, and climate change have catalyzed changes in forest health and wildfire protection policies of land management agencies. These changes subsequently prompted research to investigate the extent to which bark beetle-altered fuel complexes affect fire b...

Spatio-temporal patterns of the Norway spruce decline in the Beskid Śląski and Żywiecki (Western Carpathians) in southern Poland

A dramatic forest decline due to the bark beetle outbreak, which occurs in the Norway spruce stands in the Western Beskidy (southern Poland) since 2003, was started after severe physiological drought during winter time. An analysis describing some spatio-temporal characteristics of this process, with special regard to the patterns of bark beetle occurrence related to root fungal diseases, is pr...

Some aspects of biology and host range of Biscogniauxia mediterranea, one of the causal agent of oak charcoal disease

Field surveys in Zagros forests located in western Iran were done to study some aspects of biology and host range of Biscogniauxia mediterranea during 2014-2016. The ability of its conidia and ascospores to cause the disease was evaluated under greenhouse condition. Ascospore viability and development of anamorph and teleomorph were surveyed under different conditions. The pathogen host range w...

Large carbon release legacy from bark beetle outbreaks across Western United States.

Warmer conditions over the past two decades have contributed to rapid expansion of bark beetle outbreaks killing millions of trees over a large fraction of western United States (US) forests. These outbreaks reduce plant productivity by killing trees and transfer carbon from live to dead pools where carbon is slowly emitted to the atmosphere via heterotrophic respiration which subsequently feed...
