Fruit fly introduction

First, this video introduces the fruit fly as an organism, including its physical characteristics, life cycle, environment, and diet. Next, the reasons why fruit flies make an excellent model organism are discussed.

For example, fruit flies are inexpensive to maintain in the laboratory, have simplified genetics, and short generation times allow for quick experiments with high sample numbers. Then, key discoveries and important Drosophila researchers, such as Thomas Hunt Morgan are profiled. Finally, applications of Drosophila research, ranging from genetics to cardiac and neurological development and disease, are provided.

This video serves as an overview of the highly-important and influential model organism that is Drosophila melanogaster.

What is it and why bother about it?

An Introduction to Drosophila melanogaster. Drosophila melanogaster, also known as the "fruit fly," is a small insect that is commonly found near ripening fruit. Drosophila is a widely used model organism for scientific research and the study of this organism has provided insight into eukaryotic genetics and human disease.

Drosophila have three main body segments--the head, thorax, and abdomen--as well as a single pair of wings, and three pairs of legs. They are between mm long and weigh about 1 mg. Females are typically larger than males. Wild-type fruit flies have large red eyes, and pale yellow or light brown bodies with black stripes on the abdomen.

The Drosophila life cycle is about 2 weeks long, and is comprised of 4 major stages: The average lifespan of Drosophila is between days, however lifespan can be affected by factors such as temperature or overcrowding.

Fruit flies are present on every continent except Antarctica. More often they are found in tropical climates, but they can adapt to colder climates by moving indoors. The typical diet for Drosophila are the microorganisms, such as yeast, that inhabit very ripe and rotting fruits and vegetables.

However in the lab, we use food composed of cornmeal, molasses, agar, sugar, yeast, and water. First, the small size of the fly makes them easy to both handle and anesthetize.

Flies are also appealing to work with because they require inexpensive equipment to maintain and house in the laboratory. Thanks to their short life cycle, it takes approximately 2 weeks from when mating is set up to generate new adult progeny.

Females are extremely fertile and can lay hundreds of eggs per day.

Therefore, experiments with flies can be conducted quickly and with very high sample numbers. Drosophila are easy to study, because their genetics are simple in comparison to mammals.Sterile Fruit Fly Release: Life history of the Mediterranean fruit fly from the standpoint of parasite introduction.

Journal of Agricultural Research 3: United States Department of Agriculture, Washington, D.C. Back EA, Pemberton CE. The Mediterranean fruit fly in Hawaii. United States Department of Agriculture Bulletin Fruit Fly Lab Introduction The major topic of this experiment was to examine two different crosses between Drosophila fruit flies and to determine how many flies of each phenotype were produced.

Phenotype refers to an individual's appearance, where as genotype refers to an individual's genes. Drosophila melanogaster is a fruit fly, a little insect about 3mm long, of the kind that accumulates around spoiled fruit.

It is also one of the most valuable of organisms in biological research, particularly in genetics and developmental biology. Introduction. The fruit fly Drosophila melanogaster has been extensively studied for over a century as a model organism for genetic investigations. It also has many characteristics which make it an ideal organism for the study of animal development and behavior, neurobiology, and .
