Steroid hormone signaling is involved in the age-dependent behavioral response to sex pheromone in the adult male moth Agrotis ipsilon

Highlights ► We cloned the EcR/USP receptor for 20-hydroxyecdysone (20E) in the moth A. ipsilon. ► EcR and USP were detected in the primary olfactory center, the antennal lobe (AL). ► 20E injection into males increased their responsiveness to sex pheromone. ► This response was suppressed by blocking...

Zusammenfassung:	Highlights ► We cloned the EcR/USP receptor for 20-hydroxyecdysone (20E) in the moth A. ipsilon. ► EcR and USP were detected in the primary olfactory center, the antennal lobe (AL). ► 20E injection into males increased their responsiveness to sex pheromone. ► This response was suppressed by blocking the activation of 20E/EcR/USP complex in AL.
