 Galleria melanella has been used as a model organism for over 85 years, and it has become increasingly popular due to its ability to survive at high temperatures, its ease of handling, and its similarity to mammals in terms of immunity. It is often used in preclinical studies to test the efficacy of drugs and other treatments, and it is also used to study the effects of infectious agents such as viruses and bacteria. Additionally, this model organism is being used to explore the effects of co-infection and toxicity. Galleria melanella is a valuable tool for studying the immunology of mammals, and it is becoming more widely accepted as a reliable model for testing the safety of new drugs and treatments.
