Extract

The larch sawfly, Pristiphora erichsonii (Htg.), is a serious defoliator of trees of the genus Larix and particularly of Larix laricina (Du Roi) K. Koch in eastern Canada. According to Reeks (1954), four outbreaks occurred in the Maritime Provinces between 1883 and 1942. Following the last outbreak, few specimens of the insect were found in New Brunswick, Nova Scotia, and Prince Edward Island until 1960 when an outbreak started near Fredericton, New Brunswick. Since, outbreaks varying in degree from moderate to severe have persisted throughout this province.

In the course of a study on the ecology and population dynamics of the insect it was found necessary to verify and separate the various developmental stages of the larvae.
