Abstract
This research was carried out in the laboratory of the Department of
Zoology, Kokrajhar Govt. College, Kokrajhar, and it delves into the life cycle,
morphology, and culturing techniques of Drosophila melanogaster under
laboratory conditions. D. melanogaster, often referred to as the fruit fly, is
a member of the Drosophilidae family. This diminutive fly is known for its
yellow-brown body and distinctive brick-red, rounded eyes, measuring roughly 3
mm in length and 2 mm in width, with females being slightly larger than males.
The fruit fly's body is segmented into the head, thorax, and abdomen. The life
cycle consists of four stages: embryogenesis, larval stage, pupal stage, and
adult stage, with sexual dimorphism evident in adults, facilitating sex
differentiation. Widely used in genetic research, fruit flies serve as a model
organism in developmental biology. Typically bred in fermenting mediums derived
from decaying vegetables and fruits, they exhibit a breeding ratio of one male
to three females. The Drosophila genus encompasses around 1,500 species, each
with unique appearances, behaviors, and breeding environments. Temperature
significantly impacts their development, as adults cannot tolerate the colder
conditions of high latitudes or areas with insufficient food sources.
Consequently, cooler environments are generally unsuitable for D. melanogaster,
often found in locations rich in food supply, such as fruit cellars.
