Abstract

Approximately 32 million cocoons of 11 species of spruce- and pine-feeding sawflies were collected in Europe and Japan from 1933 to 1940 and sent to the Belleville laboratory for rearing parasites for release in Canada against the European spruce sawfly, Diprion hercyniae (Htg.). Over half a million of the cocoons were Diprion polytomum (Htg.) and the parasites that emerged from these were discussed in previous papers (Finlayson and Reeks, 1936; Finlayson and Finlayson, in preparation). In addition to cocoons, almost half a million eggs of Neodiprion sertifer (Geoff.) were collected in Europe and reared to obtain egg parasites.
