Extract

In the course of studles on different species of defoliators in field-spruce stands on the Gaspé coast of the Baie des Chaleurs, Griselda radicana (Wlshm.) occurred fairly commonly in such stands. Although the principal host tree of this insect is white spruce, Picea glauca (Moench) Voss, records of the Forest Insect and Disease Survey show that it has been collected from black spruce, Picea mariana (Mill.) BSP., Colorado spruce, Picea pungens Engelm., and balsam fir, Abies halramea (L.) Mill. Although G. radicana is commonly found across Canada, there are no records that it has ever reached outbreak proportions. These investigations were undertaken since nothing was known on the life history and habits of this insect. The studies were carried out near New Richmond in the Gaspé Peninsula in the summer of 1959.
