The high synthesis cost, however, has restricted large-scale application. Plant-based biofactories provide a promising, sustainable route for cost-effective production that could facilitate the broader use of pheromone-based pest control. Mating disruption of the yellow peach moth, Conogethes punctiferalis--a serious pest of fruit trees and field crops in East Asia--can be achieved using (E)-10-hexadecenal and (Z)-10-hexadecenal, two components of its sex pheromone.
