THE CAPSULE AND ITS RELATION TO THE EMBRYOGENESIS OF THE ICHNEUMONID PARASITOID MESOLEIUS TENTHREDINIS MORL. IN THE LARCH SAWFLY, PRISTIPHORA ERICHSONII (HTG.) (HYMENOPTERA:TENTHREDINIDAE)
Eggs of the parasitoid Mesoleius tenthredinis Morl. from British Columbia develop and hatch in approximately 120 hours when reared at 23 ± 0.5 °C and a relative humidity of 72 ± 2% within field-collected larch sawfly (Pristiphora erichsonii (Htg.)) larvae from British Columbia and Newfoundland, and...
