2023
This video describes how to dissect and isolate the adult Drosophila brain–a procedure necessary for visualizing the organ, which is otherwise obscured by the cuticle, eye, and tracheal tissue. The example protocol shows a detailed demonstration yielding high-quality preparations that can be used for immunostaining and imaging methods in Drosophila neurobiology.

In insects, the oenocytes produce cuticular hydrocarbon compounds. These compounds protect against desiccation and facilitate chemical communication. Here we demonstrate a dissection technique used to isolate the oenocytes from adult Drosophila melanogaster, and illustrate how this preparation can be utilized to study genes involved in hydrocarbon synthesis.

This video demonstrates the dissection and mounting of brain explants from Drosophila larvae. The central nervous system (CNS), attached to eye disks, is extracted from the larvae and then mounted on a glass slide in a physiological saline solution.
FAQs
Immobilization keeps the mature fly steady while the investigator works, and the stereomicroscope provides a controlled view of small anatomical structures. Together, these conditions support precise handling and help the investigator distinguish organs and tissues without introducing unnecessary movement. This is especially important when the goal is to compare body organization or relate visible anatomy to physiological or genetic functions.
The cuticle must be opened carefully because the internal structures being examined lie beneath this external covering. Fine instruments allow the investigator to expose those structures while minimizing damage. Preserving their organization improves the reliability of anatomical identification and makes comparisons among flies more meaningful, particularly when studying developmental changes, mutations, or experimental conditions.
Exposed organs and tissues provide visible evidence that can be connected with physiological or genetic functions. By comparing anatomical features among mature flies, investigators can examine how developmental processes, mutations, or experimental conditions affect body organization. The technique therefore links observable structure with broader biological questions rather than limiting analysis to external appearance.
A basic workflow begins by immobilizing the specimen and securing it for observation under a stereomicroscope. The investigator then uses fine instruments to open the cuticle carefully, exposing internal organs and tissues while minimizing structural damage. Once the anatomy is visible, the structures can be identified, compared, and interpreted in relation to the biological question.
Adult fly dissection makes internal organs and tissues directly available for examination. This allows researchers or students to identify anatomical features, compare organ systems, and assess differences in body organization. The resulting observations can provide direct evidence of how a specimen’s internal structure relates to physiological function, genetic effects, developmental processes, or experimental treatment.
The method is useful when a study or lesson requires direct examination of internal anatomy in a model organism. In instruction, it supports learning about organ systems and body organization. In research, it helps investigate how mutations, developmental processes, or experimental conditions influence mature fly anatomy, connecting visible structural outcomes with physiological or genetic questions.
