Abstract
The disruption of insect mating with sex pheromones by the air permeation technique is a complex problem influenced by a number of variables. Not least among these is the actual atmospheric concentration of pheromone during the course of the experiment. While closely related to the measured release rate from a formulation, the atmospheric concentration should be regarded separately since a number of other factors may intervene, e.g., chemical instability, foliage adsorption, and the differential effects of formulation weathering in the laboratory and the field.The present study was conducted in conjunction with small scale field trials involving an aerially applied hollow fiber formulation of the sex pheromone of the spruce budworm, Choristoneura fumiferanu (Clem.), I1 -tetradecenal (97:3::E:Z). (Hereafter referred to as pheromone.)Keywords
