The regulation of Δ11-desaturase gene expression in the pheromone gland of Mamestra brassicae (Lepidoptera; Noctuidae) during pheromonogenesis

Highlights • Pheromone blend in Mamestra brassciae is 93:7 (Z11-16Ac:16Ac) showing a daily rhythm. • Δ11-desaturase gene expression increases to a plateau at the end of first adult day. • Mambr -PT induces pheromone production but doesn’t influence Δ11-desaturase expression. • Mating reduces pheromo...

Zusammenfassung:	Highlights • Pheromone blend in Mamestra brassciae is 93:7 (Z11-16Ac:16Ac) showing a daily rhythm. • Δ11-desaturase gene expression increases to a plateau at the end of first adult day. • Mambr -PT induces pheromone production but doesn’t influence Δ11-desaturase expression. • Mating reduces pheromone synthesis, but has no effect on Δ11-desaturase expression. • No lipid droplets are found in PG cells; PBAN stimulates de novo fatty acid synthesis.
