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 کاملThe effect of larval interaction on viability in Drosophila melanogaster. II. Changes in age structure.
HE degree of heterozygosity carried by competing genotypes in single generTation cultures of Drosophila meknogaster segregating for ebony (ell) and wild type has been shown to be a factor affecting their relative fitnesses (DAWOOD and STRICKBERGER 1964). Since these results also indicated that the fitness advantages of at least one of the segregating genotypes (+/e) was associated with rapid de...
متن کاملBiological stoichiometry of growth in Drosophila melanogaster.
We examined the relationship between growth rate, C:N:P stoichiometry, and nucleic acid content in Drosophila melanogaster. The "Growth Rate Hypothesis" predicts that N and P contents per unit body mass will be high during ontogenetic stages characterized by rapid growth, reflecting the large requirement for P-rich ribosomal RNA during these periods. The ratio of RNA:DNA also is predicted to ch...
