Abstract

Hollow fibers containing a mixture of synthetic sex attractants of western pine shoot borer, Eucosma sonomana Kearfott, were applied by an airplane to 19 ha of ponderosa pine plantations in southern Oregon. Nominal dosage was 15 g active ingredient per hectare. A behavioral evaluation of treatment effects, based on moth responses to pheromone-baited traps, showed nearly 100% disruption of female to male sex pheromone communication. Tree damage in treated areas was reduced by an average of 67% for terminal shoots and by 79% for terminal and lateral shoots combined.
