Dissection 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 کاملMagnetic compass orientation by larval Drosophila melanogaster.
We report evidence for magnetic compass orientation by larval Drosophila melanogaster. Groups of larvae were exposed from the time of hatching to directional ultraviolet (365nm) light emanating from one of four magnetic directions. Larvae were then tested individually on a circular agar plate under diffuse light in one of four magnetic field alignments. The larvae exhibited magnetic compass ori...
متن کاملLarval 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 کاملSurvival of heat stress with and without heat hardening in Drosophila melanogaster: interactions with larval density.
Survival of a potentially lethal high temperature stress is a genetically variable thermal adaptation trait in many organisms. Organisms cope with heat stress by basal or induced thermoresistance. Here, we tested quantitative trait loci (QTL) for heat stress survival (HSS) in Drosophila melanogaster, with and without a cyclic heat-hardening pre-treatment, for flies that were reared at low (LD) ...
متن کاملQuantitative trait loci for life span in Drosophila melanogaster: interactions with genetic background and larval density.
The genetic architecture of variation in adult life span was examined for a population of recombinant inbred lines, each of which had been crossed to both inbred parental strains from which the lines were derived, after emergence from both high and low larval density. QTL affecting life span were mapped within each sex and larval density treatment by linkage to highly polymorphic roo-transposab...
