Sequential observations in lodgepole pine (Pinuscontorta Dougl.) and Scots pine (P. sylvestris L.) showed that the second season's shoot was not produced solely from stem units in the terminal resting bud as previously assumed. The stem units held in the rosette of primary needles surrounding the terminal bud elongated to form most of the second season's shoot. The terminal bud only contributed 29 to 54% of the stem units. There was a marked difference between an inland and a coastal provenance of lodgepole pine in the appearance of the shoot apex at the end of the first growing season.

AbstractAn outbreak of Neodiprion sertifer (Geoffroy) was studied in a lodgepole pine plantation. It was the first tree generation on a 60-ha peatland area. The nuclear polyhedrosis virus (NPV) of N. sertifer was not found in the larval population or in the soil. Within a 1.7-ha experimental plot, a 0.35-ha block was treated with NPV and the ensuing epizootic was studied during three successive summers. The treatment caused 50% mortality of fourth- and fifth-instar larvae. The NPV persisted in the treated block and gradually dispersed into the adjacent blocks. After 2 years, larval mortality was 78% in the treated block and 21% at a distance of 110–125 m from it. The larval population remained at a high level and the outbreak expanded from the experimental plot to the entire 60-ha area in the years following the virus treatment, but few virus-diseased colonies were observed outside the experimental plot. Thus, the capability of this NPV to persist and spread was not sufficient to control and contain the sawfly outbreak.
