is a major cause of tree damage and death in forests of firs (Abies) in the western United States. Sporadic outbreaks in both old- and second-growth stands have occurred one or more times each decade since in California and Oregon, and several epidemics have severely depleted fir stands elsewhere Cited by: Similarly, the pine engraver beetle (I.
pini) and the Arizona five-spined ips (I. lecontei) killed millions of ponderosa pine during the same time span throughout Arizona. Some outbreaks are associated with human activities that create large amounts of.
Fir engraver and Douglas-fir beetle numbers were monitored during and after an outbreak of the Douglas-fir tussock moth. The population behavior of the two species of bark beetles was similar. Number of emerged offspring/female was highest during the years of defoliation and declined afterward.

Grand fir and noble fir are vulnerable to engraver beetles that attack true firs of all sizes. Douglas-fir trees in some foothills around the Willamette Valley are afflicted with Swiss needle cast. The disease produces a pale overall appearance and sparse crown as individual needles turn yellow and drop.

conditions may become infested with fir-engraver beetle (Scolylus ventralis), silver fir beetle (Pseudohylesinus sericeus), or fir root bark beetle (Pseudohylesinus granulatus). In large numbers, these beetles may kill entire trees before any symptoms are observed. Pacific silver firs are also susceptible to Western spruce budworm.

The term remains current in the art trade, and there is no easy alternative in English to distinguish the works of "fine art" produced in printmaking from the vast range of decorative, utilitarian and popular prints that grew rapidly alongside the artistic print from the 15th century onwards.The fir engraver (Scolytus ventralis) belongs to the family of insects called bark beetles, which live between the bark and wood of host trees and is currently affecting grand fir.
