  9. A novel fatty acyl desaturase from the pheromone glands of Ctenopseustis obliquana and C. herana with specific Z5-desaturase activity on myristic acid.

    Journal of Chemical Ecology 40(1):63 (2014) PMID 24408442 PMCID PMC3909261

    Sexual communication in the Lepidoptera typically involves a female-produced sex pheromone that attracts males of the same species. The most common type of moth sex pheromone comprises individual or blends of fatty acyl derivatives that are synthesized by a specific enzymatic pathway in the fema...
  10. Sex pheromone biosynthetic pathways are conserved between moths and the butterfly Bicyclus anynana.

    Nature Communications 5:3957 (2014) PMID 24862548 PMCID PMC4050330

    Although phylogenetically nested within the moths, butterflies have diverged extensively in a number of life history traits. Whereas moths rely greatly on chemical signals, visual advertisement is the hallmark of mate finding in butterflies. In the context of courtship, however, male chemical si...
  11. A plant factory for moth pheromone production.

    Nature Communications 5:3353 (2014) PMID 24569486 PMCID PMC3948062

    Moths depend on pheromone communication for mate finding and synthetic pheromones are used for monitoring or disruption of pheromone communication in pest insects. Here we produce moth sex pheromone, using Nicotiana benthamiana as a plant factory, by transient expression of up to four genes codi...
