Abstract

Weevil Damage in Nursery.

Abstract

During dry weather from mid-April to mid-May 1938, adults of Barypithes pellucidus, Boh., caused considerable damage in a forest nursery in Devon. The weevils were first observed attacking the bark near ground level of small Weymouth pines [Pinus strobus] that were already showing fructifications of the rust fungus, Cronartium ribicola. They were then found to be present in considerable numbers in the soil throughout two neighbouring beds of seedlings of European larch [Larix decidua] and Sitka spruce [Picea sitchensis], many of which were dying off as a result of injury to the bark. They were successfully trapped by placing billets, about 9 ins. long and 2 ins. in diameter, at intervals of about 3 ft. from each other. These were examined daily, and the weevils collected and destroyed.
