Abstract	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.
