Larval Viability and Genetic Load in DROSOPHILA MELANOGASTER.
EXPERIMENTS on the effects of concealed genetic load in Drosophila on the viability of its homozygous or heterozygous carriers have been made by many investigators in several species (DOBZHANSKY, HOLZ and SPASSKY 1942; IVES 1945; DAWOOD 1961 and other workers). In these experiments, survival from egg to the adult stage was taken as a measure of the viability. In practice, however, the survival ...
متن کاملDissection of larval CNS in Drosophila melanogaster.
The central nervous system (CNS) of Drosophila larvae is complex and poorly understood. One way to investigate the CNS is to use immunohistochemistry to examine the expression of various novel and marker proteins. Staining of whole larvae is impractical because the tough cuticle prevents antibodies from penetrating inside the body cavity. In order to stain these tissues it is necessary to disse...
متن کاملFunctional analysis of the larval feeding circuit in Drosophila.
The serotonergic feeding circuit in Drosophila melanogaster larvae can be used to investigate neuronal substrates of critical importance during the development of the circuit. Using the functional output of the circuit, feeding, changes in the neuronal architecture of the stomatogastric system can be visualized. Feeding behavior can be recorded by observing the rate of retraction of the mouth h...
متن کاملCharacterization and genetic analysis of Drosophila melanogaster photobehavior during larval development.
In Drosophila melanogaster, during the mid third instar of development larvae cease foraging and commence a period of increased locomotor activity referred to as wandering behavior. In this study, we quantified the wild type larval response to light during the foraging (first, second, and early third instars) and wandering (late third instar) stages of development. Foraging larvae in the first,...
متن کاملAnalysis of Drosophila larval feeding response to quinine-adulterated food.
The food responses of Drosophila larvae offer an excellent opportunity to study the genetic and neural regulation of feeding behavior. Compared with fed larvae, hungry larvae are more likely to display aggressive foraging, rapid food intake, compensatory feeding, and stress-resistant food procurement. Omnivores, including humans, tend to avoid noxious or unfamiliar food. Fly larvae avoid bitter...
