Ecdysteroid titers were determined by radioimmunoassay during prepupal, pupal, and adult
development, and during adulthood in Drosophila melanogaster males and females …

Vitellogenesis in Drosophila is regulated by the sex-determination gene pathway, the
hormones ecdysone and juvenile hormone and the availability of nutrients. In this paper I …

Sexual reproduction in metazoans requires the development of sexually differentiated
structures, which then function at times determined by physiological and environmental …

The roles of the JHs and ecdysteroids in ovarian maturation of adult Aedes aegypti, A.
atropalpus, Musca domestica and Drosophila melanogaster have been characterized by …

Many of the genes in the regulatory hierarchy controlling sex determination in Drosophila
melanogaster are known. Here we examine how this regulatory hierarchy controls the …

In retrospect, the range of topics covered in this monograph, although forming a coherent
ensemble, is so extensive that a detailed discussion could easily extend to three or four …

To elucidate the role of the juvenile hormone (JH) in the control of Drosophila reproduction
under stress, JH degradation, dopamine (DA) content and reproduction were studied upon …

The effect of an experimentally increased octopamine content (feeding flies with OA) on the
levels of juvenile hormone (JH) degradation, dopamine (DA), and 20‐hydroxyecdysone …

Radioimmunoassay of in vitro culture medium from ovaries of Drosophila melanogaster
indicates that detectable ovarian ecdysteroid synthesis begins between 6 and 12 h after …

Juvenile hormone (JH) degradation was studied under normal and stress conditions in
young and matured females of Drosophila melanogaster strains having mutations in …
