Abstract
Orfralure [93% (Z), 7% (E)-8-dodecen-1-ol acetate], the synthetic pheromone of the oriental fruit moth,Grapholitha molesta (Busck), was released into the air of orchard test plots either by hanging plastic laminated dispensers on trees or by aerial dispersal of microcapsules containing a solution of the lure. Trap catch was reduced 95% or more with the most effective formulations, but consistently higher reductions were produced by the dispensers. In tests as long as 28 weeks with dispensers, a single retreatment at midseason maintained an effective concentration.
