The sequencing of the genome for an important parasitic wasp called Nasonia has been completed by Agricultural Research Service (ARS) scientists and cooperators. Nasonia is a key experimental organism that's been used for genetic research for over half a century.
The ARS research was led by entomologist Wayne Hunter at the U.S. Horticultural Research Lab in Fort Pierce, Fla.
The small Nasonia wasps seek out blow flies, flesh flies, and house flies, and then lay their eggs in the fly pupae. It's an effective biocontrol wasp because the females produce offspring quickly, have large family sizes and, best of all, are easy to work with in the lab. Commercial hosts are available, making it easy to rear the wasps.
Currently U.S. biological control programs using parasitoid wasps save approximately $20 billion annually in crop losses to newly invasive species. These wasps have been a major benefit to food production for humans by reducing the quantity of food crops destroyed by pests and reducing the need for pesticides.
It's no wonder that Nasonia was the logical 1st choice for sequencing a parasitoid genome. Information from the Nasonia genome is being used to identify important genes in parasitoid biology. There's also a broad interest in utilizing the Nasonia genome to identify genes involved in important biological processes like sense of smell, behavior, toxicology and enzymatic pathways.
Collaborating with Hunter are ARS National Plan Leader Kevin Hackett and University of Rochester (New York) genetics professor Jack Werren. The scientific team produced genetic libraries and sequenced over 10,000 expressed sequence tags of the genome.
