Welcome to the National Drosophila Species Stock Center (NDSSC) Homepage.  This site is currently under construction and will be updated soon.  We are now taking orders for stocks (see below).

Our Collection

The NDSSC currently maintains a living collection of over 250 Drosophila species represented by approximately 1600 stocks that are used by biological researchers focusing on questions in evolution, ecology, developmental biology, physiology, neurobiology, comparative genomics, and immunology. Each species in the Center varies with respect to the number of strains maintained, reflecting factors such as close phylogenetic relationship to species with sequenced genomes, the presence of genetically marked or transgenic stocks, the availability of stocks from diverse collection localities, and the ease with which stocks can be obtained and reared.

The links in the menu above have detailed information with regard to food recipes and husbandry requirements for individual stocks. We welcome feedback and comments so please let us know if you have any questions or suggestions. Please let us know if you would like to make a donation to our collection, or have a request for a particular species we are not currently maintaining.

Ordering Stocks

***Our last shipping date for this season is December 17, 2018 so please get your orders in soon. We will resume shipments on January 7, 2019. Have a wonderful holiday season***

The Cornell University Drosophila Species Stock Center provides subcultures of over 250 different Drosophila species. While the basic operating expenses of the Stock Center are funded by the National Science Foundation, we are required to charge for the stocks to recover some of the costs. The charge for a subculture of all available species is $40 plus shipping. For each stock ordered we send one vial containing eggs and larvae, and one vial containing ~30-50 adults.

In addition to the permanent collection, the Stock Center periodically offers recent collections of isofemale lines on a limited-time basis. Investigators lacking grant support may petition the Stock Center for a waiver of fees by contacting the Stock Center director.

Permits

Permits are not required for most of the species currently held by the stock center.  Domestic and international users will need USDA permits for the two pest species we maintain, Drosophila suzukii and Zaprionus indianus.  Permit applications can be made on the USDA APHIS website.  International users should check with their home countries to determine whether they require additional permits.

To place an order please send an email with the species name and stock number from the inventory list below to: Drosophila@cornell.edu
