1. How Do Flies Get Drunk and What Are the Signs?
Yes, flies get drunk, just like humans do. According to research from Scripps Research, in December 2018, flies exhibit similar signs of intoxication to humans, such as loss of coordination and hyperactivity.
1.1. What Happens When Flies Consume Alcohol?
When flies consume alcohol, they experience a range of effects that mirror human intoxication. These effects occur due to ethanol impacting nerve cells, specifically, according to a study published in the Journal of Molecular Biology, alcohol molecules employ intermediary molecules on the surface of the neuron to produce the intoxicating effect, indirectly. This process leads to observable behavioral changes:
- Initial Hyperactivity: Flies initially become more active, running around with increased energy. Scott Hansen, PhD, associate professor in the Department of Molecular Medicine at Scripps Research, likens this stage to the “buzzed” feeling humans experience.
- Loss of Coordination: As the alcohol takes effect, flies start to lose their coordination. This is a clear sign of intoxication, similar to how humans struggle with balance and motor skills when drunk.
- Sedation: Following the hyperactivity, flies enter a state of sedation. This is the anesthetic-like effect of alcohol, where the flies become less responsive and more subdued.
1.2. What Is the Role of Phospholipase D2 (PLD2) in Fly Intoxication?
Phospholipase D2 (PLD2) plays a crucial role in how flies become intoxicated. PLD2 is an enzyme found on nerve cell membranes. According to research from Scripps Research, this enzyme links ethanol molecules to lipid (fat) in the membrane of the nerve cell.
