The role of juvenile hormone in the control of reproductive function in Drosophila virilis under nutritional stress.

To investigate the role of juvenile hormone ( JH) in the control of Drosophila reproduction under stress, JH degradation and reproduction were studied under nutritional stress and JH treatment in Drosophila virilis females of wild type (wt) and a heat stress (hs) mutant: this mutant does not respond to heat stress by alterations in JH metabolism and has decreased JH level and fertility under normal conditions. One day of starvation results in a decrease of JH degradation, a delay in oocyte maturation, degradation of early vitellogenic egg chambers, accumulation of mature oocytes and a 24 h oviposition arrest in both wt and hs females. A fertility decrease was observed in both wt and hs females 24 h following the end of starvation. JH treatment leads to a decrease of JH degradation and an arrest of oviposition for 24 h in fed females. JH treatment prior to starvation seems to protect some oocytes from resorption: in JH-treated wt females, fertility increases rapidly following the end of starvation. The dynamics of JH degradation and fertility are similar following starvation and JH treatment. The role of JH in the accumulation of mature oocytes and the delay of oviposition under stress are discussed.[1]
