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 کاملThe role of larval fat cells in adult Drosophila melanogaster.
In the life history of holometabolous insects, distinct developmental stages are tightly linked to feeding and non-feeding periods. The larval stage is characterized by extensive feeding, which supports the rapid growth of the animal and allows accumulation of energy stores, primarily in the larval fat body. In Drosophila melanogaster access to these stores during pupal development is possible ...
متن کاملMitosis in primary cultures of Drosophila melanogaster larval neuroblasts.
Although Drosophila larval neuroblasts are routinely used to define mutations affecting mitosis, the dynamics of karyokinesis in this system remain to be described. Here we outline a simple method for the short-term culturing of neuroblasts, from Drosophila third instar larvae, that allows mitosis to be followed by high-resolution multi-mode light microscopy. At 24 degrees C, spindle formation ...
متن کاملIsolation of larval behavioral mutants in Drosophila melanogaster.
Genetic loci that influence behavior are often difficult to identify and localize in part due to the quantitative nature of behavioral phenotypes. Previous studies had found an association between pupal lethality and altered larval behavior for mutants of several genes. To facilitate the identification and localization of new mutants that influence larval foraging (movement in the presence of f...
