Author: Smith, Richard H.

Date: 1967

Source: Res. Note PSW-RN-119. Berkeley, CA: U.S. Department of Agriculture, Forest Service, Pacific Southwest Forest and Range Experiment Station. 12 p

Station ID: RN-PSW-119

Description: Success--defined as oviposition or tree-killing--was obtained by attracting western pine beetles to groups of pines with natural attractants and by en-massed forced attacks on individual trees combined with either physical or biological stress. Preliminary results show considerable agreement with laboratory tests of vapor toxicity.
