Collecting virgin females has just gotten easier with our Easy Fly® Drosophila strains. Use them to replace the strain you would normally use for manual virgin collection. Fly stock undergoes heat shock treatment prior to shipping, which kills the males.

Carolina® Easy Fly® Drosophila cultures

  • Time saver
  • Error-free system
  • Females same as normal stocks

The Easy Fly® system works by selectively killing male larvae with a 2-hour heat shock treatment, leaving only virgin females alive. Easy Fly® males contain a modified Y* chromosome with a gene that activates programmed cell death when larvae are exposed to high temperatures. Since only males have a Y* chromosome with this gene, female larvae are unaffected. Carolina performs the heat shock treatment in our laboratories, so all shipped cultures contain only virgin females. All flies are placed in a vial with food for shipping.

Note: Please order at least 2 weeks in advance of desired ship date.

 
 
 
Rated 5 out of 5 by from Great Time Saver & High Quality Product Product is exactly as described. Vial contained all virgin females (which meant there were no larvae and other adults). They were used in a cross several weeks after so I am impressed by how great these cultures were and how long they lasted. It definitely helps save time over trying to gather your own virgin flies.

Rated 5 out of 5 by from This product saves time and is an educational tool I used to spend 2 weeks laboriously collecting virgin flies by getting up early and staying up late. Now I just order them for the day before I want to do my crosses and I'm set. They are also a useful example to use in my genetics unit to explain genetic manipulation and modification of a species genome.

Rated 2 out of 5 by from Not what expected I assumed by the description that I would be receiving a vial of virgin flies, larvae, pupae and adults, and that I could expect to be able to collect large numbers of virgin flies as the pupae eclosed. Unfortunately the vial only contains "25-30 adults" and no pupae or larvae. While the documentation does state "some of these may die in-transit due to their short life spans" I would say that the majority of them are dead, and that I have between 5-10 living flies. I would not by any means consider this a large number of virgins. This number is not very helpful for setting up a large number of crosses for a class. Glad I purchased ahead of time to see the product first. It isn't much of a time saver either, as you need to order the product 2 weeks in advance, in that same period of time I was able to amplify a non-easy fly stock and have the first round of virgins emerging and will be able to collect more virgins than what is provided in this vial.
