Juvenile Hormone Is Required in Adult Males for Drosophila Courtship
Juvenile Hormone (JH) has a prominent role in the regulation of insect development. Much less is known about its roles in adults, although functions in reproductive maturation have been described. In adult females, JH has been shown to regulate egg maturation and mating. To examine a role for JH in male reproductive behavior we created males with reduced levels of Juvenile Hormone Acid O-Methyl...
متن کاملDifferential Juvenile Hormone Variations in Scale Insect Extreme Sexual Dimorphism
Scale insects have evolved extreme sexual dimorphism, as demonstrated by sedentary juvenile-like females and ephemeral winged males. This dimorphism is established during the post-embryonic development; however, the underlying regulatory mechanisms have not yet been examined. We herein assessed the role of juvenile hormone (JH) on the diverging developmental pathways occurring in the male and f...
متن کاملJuvenile hormone mediates sexual dimorphism in horned beetles.
The causes and consequences of sexual dimorphism are major themes in biology. Here we explore the endocrine regulation of sexual dimorphism in horned beetles. Specifically, we explore the role of juvenile hormone (JH) in regulating horn expression in females of two species with regular sexual dimorphism for pronotal horns (females have much shorter horns than males) and a third species with a r...
متن کاملJuvenile Hormone in Insects
■ Abstract The mevalonate pathway in insects has two important peculiarities, the absence of the sterol branch and the synthesis of juvenile hormone (JH), that may have influenced the mechanisms of regulation. The data available on these mechanisms indicate that cholesterol does not play a regulatory role and that JH modulates transcript levels of a number of genes of the mevalonate pathway or ...
متن کاملIs sexual erotica associated with sexual deviance in adolescent males?
Within the last few years, there has been a tremendous increase in the availability of highly sexually explicit material, specifically with the introduction of adult videos. Many people feel that such easy access to sexually explicit material will mean an increase in sexually related crime, and a more cavalier attitude towards sex in general (Attorney General’s Commission on Pornography, 1986)....
