Heavy metal concentrations (Cu, Fe, Ni, Cd) in the cocoons of three gregarious pine diprionids, Gilpinia socia, Diprion pini and Neodiprion sertifer, were compared between the species and sexes. The sawflies were reared in the laboratory in colonies from the first instar larvae, being fed on Scots pine (Pinus sylvestis) needles collected from a heavily polluted or a relatively unpolluted site. The levels of copper, iron and nickel were two to three times as high in N. sertifer as in the two other species. Cadmium showed bioaccumulation in all three species. In N. sertifur and G. socia reared on polluted needles, the metal concentrations were higher in males than in females.

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.
