Fitness of karyotypes in Drosophila pseudoobscura.
In the dynamics of the survival of chromosomal polymorphism selection may be operating at the genic level, at the chromosomal level or at the supergene level. Tests designed to distinguish between these levels were run on Drosophila pseudoobscura. There was no evidence for heterosis, a necessary requirement for gene-determined chromosomal polymorphism A strong chromosmal selection was observed....
متن کاملJuvenile 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 کاملDietary glucose regulates yeast consumption in adult Drosophila males
The adjustment of feeding behavior in response to hunger and satiety contributes to homeostatic regulation in animals. The fruit fly Drosophila melanogaster feeds on yeasts growing on overripe fruit, providing nutrients required for adult survival, reproduction and larval growth. Here, we present data on how the nutritional value of food affects subsequent yeast consumption in Drosophila adult ...
متن کاملSmoking among Adult Males
Smoking is the single most important avoidable cause of premature morbidity and mortality in the world. It is a major public health problem in Pakistan. The objectives of this study were to assess smoking status and its relationship to socio-demographic characteristics, and to determine the behavior of male smokers in an urban community in Karachi, Pakistan. A cross-sectional, household survey ...
متن کاملDissection of oenocytes from adult Drosophila melanogaster.
In Drosophila melanogaster, as in other insects, a waxy layer on the outer surface of the cuticle, composed primarily of hydrocarbon compounds, provides protection against desiccation and other environmental challenges. Several of these cuticular hydrocarbon (CHC) compounds also function as semiochemical signals, and as such mediate pheromonal communications between members of the same species,...
