Press Release Provided by CA Department of Pesticide Regulation
The California Department of Pesticide Regulation (DPR) has initiated the review of a research authorization requested by Oxitec, Ltd to release and study the use of genetically engineered Aedes aegypti mosquitoes to reduce the current Aedes aegypti mosquito population in Tulare County, California. DPR’s review of the research authorization application will entail a rigorous scientific evaluation, consultation with government agencies and consideration of public comments and input. DPR anticipates that the evaluation and review process will take at least several months.
The department opened a 15-day public comment period beginning April 5 and ending on April 19 at 5 p.m. to collect information and feedback from the public to be considered as part of the review and evaluation process for the application. Comments will be accepted via email at Mosquito.RA@CDPR.CA.gov.
DPR must approve a research authorization application before an unregistered pesticide can be field tested in the state. DPR toxicologists, entomologists, microbiologists, ecotoxicologists, and other department scientists will review the application, research design, scientific studies, and additional information.
Research authorizations are approved or refused based on an evaluation of whether that research may involve a hazard to handlers or field workers, public health, or the environment. Approved research authorizations limit both the area and the time period that the product may be tested and may include strict requirements or limitations on use, as well as monitoring and reporting requirements.
DPR’s evaluation of the research authorization application will include consultation with the California Department of Public Health, the County Agricultural Commissioner’s Office, the Delta Mosquito and Vector Control District and other appropriate government and local agencies.
Oxitec’s research authorization application proposes conducting field studies in Tulare County, California. The application submitted by the company proposes to release 5,000-30,000 mosquitoes per week at multiple study sites located within the county. The company has not yet identified specific sites for the release—a requirement for DPR’s review of the research authorization application. The proposed locations of the release sites, number of sites necessary to conduct the requested research and the number of mosquitoes released per site will be evaluated by DPR as part of its review of the application.
The department has posted on its website the following documents submitted by Oxitec as part of its research authorization application:
- Application for research authorization from Oxitec, Ltd
- U.S. EPA documents submitted to DPR by Oxitec related to its research authorization application
