This study explores the relationship between seasonal variations and the development rates of Drosophila Melanogaster. Flies are closely monitored in a controlled laboratory setting after being transferred from outdoor cages across different seasons. In the outdoor cages, the introduction of the bacterial strain A. orientalis DmW_045, commonly referred to as '45,' enhances development rates and ensures consistent data collection. Axenic flies, created by thoroughly sterilizing fly eggs with bleach to eliminate external bacteria, are employed to isolate genetic influences on the relationship between season and development rates. The core methodology involves two groups: axenic flies treated with '45' and a control group unexposed to '45.' This approach guarantees data accuracy and assesses development rates based purely on genetics. Development rates are measured by marking eclosed (hatched) pupae on vials at specific intervals. The research seeks to unveil the correlation between seasonal variations and fly development rates, shedding light on the role of seasonal factors in shaping development. This study explores the interplay between seasonal variations and Drosophila fly development, emphasizing genetics and environmental factors. Its potential significance lies in providing insights beneficial for ecological and genetic studies, potentially offering a clear genetic link between seasons and development rates that can enhance our understanding of the natural world.
