The Pitch Canker Epidemic in California.
TLDR
Native Monterey pine (Pinus radiata D. Don) forests are currently found at three disjunct locations in coastal California and on two islands off the coast of Mexico, which are significant ecological and recreational resources, but they are also a valuable repository of useful genetic traits for improved varieties of Monterey Pine, which is widely used by the timber industry.

Pitch canker disease in California: pathogenicity, distribution, and canker development on Monterey pine (Pinus radiata)
TLDR
All 167 isolates of F. subglutinans recovered from diseased tissue, insects, and air samples in California were virulent on Monterey pine in greenhouse pathogenicity tests. Expand
Chiral specificity in responses by the bark beetleDendroctonus valens to host kairomones
TLDR
The attraction of the red turpentine beetle to the resin volatiles of its host,Pinus ponderosa, is elicited by three chiral monoterpenes, demonstrating the importance of chirality of host compounds in the host finding behavior of this bark beetle. Expand
Nature and ecological implications of pathogen-induced systemic resistance in conifers: A novel hypothesis
TLDR
It is hypothesize that systemic-induced resistance represents a common and important phenomenon in coniferous trees, allowing for a balanced allocation of resources between growth and defense. Expand
Pheromonal attraction and allomonal interruption ofIps pini in California by the two enantiomers of ipsdienol
Air containing volatile compounds from around maleIps pini boring in ponderosa pine logs from California was condensed, fractionated by GC, and assayed in the laboratory and field. The only fractionExpand
Responses of oaks and tanoaks to the sudden oak death pathogen after 8 y of monitoring in two coastal California forests
TLDR
Sudden oak death, caused byPhytophthora ramorum, is widely established in mesic forests of coastal central and northern California and through early 2008, the numbers of newly infected trees increased for all species. Expand
Sudden oak death in California: Disease progression in oaks and tanoaks
TLDR
Sudden oak death (SOD), caused by Phytophthora ramorum, is killing oaks and tanoaks in the Coast Ranges of California, from Monterey County to Humboldt County, to characterize the progress of disease symptoms, and to determine the fidelity of the association of three or more bark and ambrosia beetle species (Coleoptera: Scolytidae). Expand
Attractive and inhibitory pheromones produced in the bark beetle,Dendroctonus brevicomis, during host colonization: Regulation of inter- and intraspecific competition
TLDR
These inhibitory pheromones appear to cause several competing species of bark beetle to avoid landing in areas infested with D. brevicomis, even when their own phersomone is present. Expand
SEMIOCHEMICALS FROM THREE SPECIES OF PITYOPHTHORUS (COLEOPTERA: SCOLYTIDAE): IDENTIFICATION AND FIELD RESPONSE
TLDR
Pityol is shown to be an aggregation pheromone component for P. carmeli and may also function as a synomone that decreases competition of P. setosus and as a kairomone for L. pertenuis. Expand
