The Fly Colonies

An overview of the fly colonies including images.

welcome to The Fly farm

At our facilities located on the Oklahoma State University Campus we are capable of maintaining several fly colonies. Currently we have House Fly and Blow Fly colonies. We are also able to maintain a Stable Fly colony as we have done in the past. 

care and management

Care and management all depend on what species of fly we are housing and what stage of production they are in. In general colonies are checked at least once a day, more if we have recently collected eggs. Temperature and humidity are two very important things when you have fly colonies. They are monitored very closely and humidifiers are filled on a daily basis. Additionally water and food are very important in maintain a colony and during the egg collecting process they are also checked and refilled daily. Eggs are collected about every 7 days they are placed into a tub with calf manna, wheat germ and water. This mixture makes a perfect environment for the eggs to turn into larvae and pupate. The pupa are then taken from the tubs and placed in a cloth cage to allow to emerge. All cages are marked with the emerging date to keep track of the age of the flies. Different experiments require different ages of flies so this is a very important step in a fly colony.  


The following images were taken in the fly room.

Preparing food for the stable flies.



Egg powder is used as a protein source to get house flies to lay eggs, they are fed sugar cubes on a daily basis.
