Eclosion assay
Eclosion assays are experimental procedures used to study the process of eclosion in insects, particularly in the model organism drosophila (fruit flies). Eclosion is the process in which an adult insect emerges from its pupal case, or a larval insect hatches from its egg. In holometabolous insects, the circadian clock regulates the timing of adult emergence. The daily rhythm of adult emergence in these insects was among the first circadian rhythms to be investigated. The circadian clock in these insects enforces a daily pattern of emergence by permitting or triggering eclosion during specific time frames and preventing emergence during other periods. The purpose of an eclosion assay is to count the number of flies that emerge over time from a developing population, which provides information on the circadian clock in the experimentally manipulated drosophila. For example, with an eclosion monitor, scientists can study how knocking out a certain gene changes the behavioral expression of a drosophila's biological clock. Additionally, the circadian rhythm of adult insect emergence was among the earliest chronobiological phenomena to be examined, significantly impacting the field of chronobiology through its contributions to understanding temperature compensation, phase response curves, and reactions to skeleton photoperiods.
