NOTES ON THE BIOLOGY OF MICROPLECTRON FUSCIPENNIS ZETT. AS A COCOON PARASITE OF DIPRION POLYTOMUM. HARTIG
Published online by Cambridge University Press: 31 May 2012
Extract
The results of a three year study of the imported parasites of Diprion polytomum show that an eulophid parasite, Microplectron fuscipennis Zett., gives promise of becoming an important control factor of the spruce sawfly in Canada. M. fuscipennis is widely distributed in Europe, and its habits there have been fully discussed by Morris and Cameron (1935) and by Ullyett (1936).
