Mountain Pine Beetle Epidemiology in Lodgepole Pine
The following brief synthesis of mountain pine beetle epidemiology is based on host-beetle interaction. In the first part I briefly describe the relationship between the dynamics of lodgepole pine and mountain pine beetle. The second part describes the phases in the infestation cycle and their main characteristics. This synthesis is based on published information on infestation behaviour in wes...

متن کاملThe Southern Pine Beetle and Pine Forest Ecosystems
Dendroctonus frontalis, the southern pine beetle (SPB), is a highly destructive species of bark beetle that inhabits pine forests in the southern United States and parts of Central America. @6D In natural pine forests, the ecological role of the SPB presumably is to hasten the demise of weak or damaged trees, perhaps creating kindling for fires that contribute positively to the long-term health...
متن کاملInduced accumulation of phenolics and sawfly performance in Scots pine in response to previous defoliation.
Phenolic compounds often accumulate in foliar tissues of deciduous woody plants in response to previous insect defoliation, but similar responses have been observed infrequently in evergreen conifers. We studied the effects of defoliation on the foliar chemistry of Scots pine (Pinus sylvestris L.) and cocoon mass, and survival of the pine sawfly (Diprion pini L.). In two successive years, needl...
متن کاملNeuroprotective Effects of Korean Red Pine(Pinus densiflora) Bark Extract and Its Phenolics.
Korean red pine (Pinus densiflora) is one of the major Pinus species in Korea. Red pine barkis removed prior to the chipping process in the wood industry and discarded aswaste. However, red pine bark contains a considerable amount of naturally occurring phenolics including flavonoids and therefore may have a variety of biological effects. In this study, we investigated if Korean red pine bark e...
