We propose a new strategy for a rational reduction of active ingredient in control of the codling moth Cydia pomonella, and the oblique band leaf roller Choristoneura rosacea by introduction of feeding enhancers into pesticide formulations. Granulated sugar substitute, Sweet'n Low®, and monosodium glutamate were identified as substances that increased leaf feeding in choice and non-choice assays. The enhancing properties of Sweet'n Low® and monosodium glutamate are maintained in the field under favorable weather conditions, however rain-fastness of these enhancers needs to be improved. We present data on rain-fastness improvement of the feeding enhancers by formulations with rain-fast particle films or matricies. Alternative ways of rain-fastness improvement included studies on gustation pharmacology.
