| dc.description |
Emerged beetles were first collected July 17 and peak emergence
occurred between August 10 and 26, 1975. Density of attacks averaged
four per 0.5 ft. 2 (0.05 m2). Parent to brood ratio was 1:4.6. Thirteen
associate insects, representing six families of Coleoptera and
one of Diptera, were recovered. Associates included predators and
secondary bark beetles. Future studies dependent on mountain pine
beetle emergence require initiation or completion prior to mid-July. |
