Abstract

1216 LETTERS TO THE EDITORS RESPONSE BY D. M. SUCKLING ET AL. We thank Dr. McDonough for his interest in our paper.

We contend that the rate of pheromone release is controlled solely by the active length of the dispenser—the length of capillary filled by the pheromone oil—and the con- ductance of the walls of the tubing dispenser. This basic scheme is thoroughly consistent with the conventional view of the control of pheromone release. For example Zeoli et al.
