Control of Eucosma sonomana by Mating Disruption With Synthetic Sex Attractant12

Abstract
Synthetic pheromone, when applied by air in ConRel® fibers or Hercon® flakes at 10 to 20 g of AI/ha, reduced damage to pines caused by larvae of a pine shoot borer, Eucosma sonomana Kearfott, by 76 to 88%. Lesser dosages of 0.2 to 2 g/ha were less effective.
