Effect of 20-hydroxyecdysone and a juvenile hormone analogue on vitellogenin production in male houseflies, Musca domestica

Male houseflies ≥ 8 h old produced vitellogenin, after treatment with 20-hydroxyecdysone, that was immunologically identical to female vitellin. When the 20-hydroxyecdysone injection was followed by the application of a juvenile hormone analogue (methoprene), the concentration of vitellogenin increa...

Zusammenfassung:Male houseflies ≥ 8 h old produced vitellogenin, after treatment with 20-hydroxyecdysone, that was immunologically identical to female vitellin. When the 20-hydroxyecdysone injection was followed by the application of a juvenile hormone analogue (methoprene), the concentration of vitellogenin increased, vitellogenin production started sooner and continued longer than it did in males treated with only 20-hydroxyecdysone. Methoprene also lowered the response threshold to 20-hydroxyecdysone for vitellogenin production. However, methoprene alone did not result in vitellogenin production and vetellogenin was never detected in any of the control males. The absence of vitellogenin in males could be partially explained by the lower ecdysteroid titre in males when compared with females.
