Control of Pine Beauty Moth by Fenitrothion in Scotland - 1978

摘要

The course of the current outbreak of Pine beauty, Panolis flammea, is described, and the failure to control it with Bacillus thuringiensis in 1977 is recorded. The technical advantages of a target-specific ultra low volume aerial spraying over conventional low volume technique is considered. A comparative trial of the ultra low volume and low volume techniques is described and the results of assessments of deposits upon the ground, on the pine needles and on larvae are given for both the trial and the later spraying operation itself. It was clear that more insecticide arrived on the target larvae and needles in ULV applications and less upon the ground. The results of environmental monitoring are reported and are largely based on a limited number of samples and insufficient time for adequate pre-spray studies.
